15 -AsyncKit provides harness for `parallel` and `serial` iterators over list of items represented by arrays or objects.  
16 -Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.  
17 -  
18 -It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

27 -## Install  
28 -  
29 -```sh  
30 -$ npm install --save asynckit  
31 -```  
32 -  
33 -## Examples  
34 -  
35 -### Parallel Jobs  
36 -  
37 -Runs iterator over provided array in parallel. Stores output in the `result` array,  
38 -on the matching positions. In unlikely event of an error from one of the jobs,  
39 -will terminate rest of the active jobs (if abort function is provided)  
40 -and return error along with salvaged data to the main callback function.  
41 -  
42 -#### Input Array  
43 -  
44 -```javascript  
45 -var parallel = require('asynckit').parallel  
46 - , assert = require('assert')  
47 - ;  
48 -  
49 -var source = [ 1, 1, 4, 16, 64, 32, 8, 2 ]  
50 - , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]  
51 - , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]  
52 - , target = []  
53 - ;  
54 -  
55 -parallel(source, asyncJob, function(err, result)  
56 -{  
57 - assert.deepEqual(result, expectedResult);  
58 - assert.deepEqual(target, expectedTarget);  
59 -});  
60 -  
61 -// async job accepts one element from the array  
62 -// and a callback function  
63 -function asyncJob(item, cb)  
64 -{  
65 - // different delays (in ms) per item  
66 - var delay = item * 25;  
67 -  
68 - // pretend different jobs take different time to finish  
69 - // and not in consequential order  
70 - var timeoutId = setTimeout(function() {  
71 - target.push(item);  
72 - cb(null, item * 2);  
73 - }, delay);  
74 -  
75 - // allow to cancel "leftover" jobs upon error  
76 - // return function, invoking of which will abort this job  
77 - return clearTimeout.bind(null, timeoutId);  
78 -}  
79 -```  
80 -  
81 -More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).  
82 -  
83 -#### Input Object  
84 -  
85 -Also it supports named jobs, listed via object.

129 -### Serial Jobs  
130 -  
131 -Runs iterator over provided array sequentially. Stores output in the `result` array,  
132 -on the matching positions. In unlikely event of an error from one of the jobs,  
133 -will not proceed to the rest of the items in the list  
134 -and return error along with salvaged data to the main callback function.

211 -_Note: Since _object_ is an _unordered_ collection of properties,  
212 -it may produce unexpected results with sequential iterations.  
213 -Whenever order of the jobs' execution is important please use `serialOrdered` method._  
214 -  
215 -### Ordered Serial Iterations

97 -## Installing  
98 -  
99 -### Package manager  
100 -  
101 -Using npm:  
102 -  
103 -```bash  
104 -$ npm install axios  
105 -```  
106 -  
107 -Using bower:  
108 -  
109 -```bash  
110 -$ bower install axios  
111 -```  
112 -  
113 -Using yarn:  
114 -  
115 -```bash  
116 -$ yarn add axios  
117 -```  
118 -  
119 -Using pnpm:  
120 -  
121 -```bash  
122 -$ pnpm add axios  
123 -```  
124 -  
125 -Once the package is installed, you can import the library using `import` or `require` approach:  
126 -  
127 -```js  
128 -import axios, {isCancel, AxiosError} from 'axios';  
129 -```  
130 -  
131 -You can also use the default export, since the named export is just a re-export from the Axios factory:  
132 -  
133 -```js  
134 -import axios from 'axios';  
135 -  
136 -console.log(axios.isCancel('something'));  
137 -````  
138 -  
139 -If you use `require` for importing, **only default export is available**:  
140 -  
141 -```js  
142 -const axios = require('axios');  
143 -  
144 -console.log(axios.isCancel('something'));  
145 -```  
146 -  
147 -For cases where something went wrong when trying to import a module into a custom or legacy environment,  
148 -you can try importing the module package directly:  
149 -  
150 -```js  
151 -const axios = require('axios/dist/browser/axios.cjs'); // browser commonJS bundle (ES2017)  
152 -// const axios = require('axios/dist/node/axios.cjs'); // node commonJS bundle (ES2017)  
153 -```  
154 -  
155 -### CDN  
156 -  
157 -Using jsDelivr CDN (ES5 UMD browser module):  
158 -  
159 -```html  
160 -<script src="https://cdn.jsdelivr.net/npm/axios@1.1.2/dist/axios.min.js"></script>  
161 -```  
162 -  
163 -Using unpkg CDN:  
164 -  
165 -```html  
166 -<script src="https://unpkg.com/axios@1.1.2/dist/axios.min.js"></script>  
167 -```  
168 -  
169 -## Example  
170 -  
171 -> **Note**: CommonJS usage  
172 -> In order to gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with `require()`, use the following approach:  
173 -  
174 -```js  
175 -import axios from 'axios';  
176 -//const axios = require('axios'); // legacy way  
177 -  
178 -// Make a request for a user with a given ID  
179 -axios.get('/user?ID=12345')  
180 - .then(function (response) {  
181 - // handle success  
182 - console.log(response);  
183 - })  
184 - .catch(function (error) {  
185 - // handle error  
186 - console.log(error);  
187 - })  
188 - .finally(function () {  
189 - // always executed  
190 - });  
191 -  
192 -// Optionally the request above could also be done as  
193 -axios.get('/user', {  
194 - params: {  
195 - ID: 12345  
196 - }  
197 - })  
198 - .then(function (response) {  
199 - console.log(response);  
200 - })  
201 - .catch(function (error) {  
202 - console.log(error);  
203 - })  
204 - .finally(function () {  
205 - // always executed  
206 - });  
207 -  
208 -// Want to use async/await? Add the `async` keyword to your outer function/method.  
209 -async function getUser() {  
210 - try {  
211 - const response = await axios.get('/user?ID=12345');  
212 - console.log(response);  
213 - } catch (error) {  
214 - console.error(error);  
215 - }  
216 -}  
217 -```  
218 -  
219 -> **Note**: `async/await` is part of ECMAScript 2017 and is not supported in Internet  
220 -> Explorer and older browsers, so use with caution.  
221 -  
222 -Performing a `POST` request  
223 -  
224 -```js  
225 -axios.post('/user', {  
226 - firstName: 'Fred',  
227 - lastName: 'Flintstone'  
228 - })  
229 - .then(function (response) {  
230 - console.log(response);  
231 - })  
232 - .catch(function (error) {  
233 - console.log(error);  
234 - });  
235 -```  
236 -  
237 -Performing multiple concurrent requests  
238 -  
239 -```js  
240 -function getUserAccount() {  
241 - return axios.get('/user/12345');  
242 -}  
243 -  
244 -function getUserPermissions() {  
245 - return axios.get('/user/12345/permissions');  
246 -}  
247 -  
248 -Promise.all([getUserAccount(), getUserPermissions()])  
249 - .then(function (results) {  
250 - const acct = results[0];  
251 - const perm = results[1];  
252 - });  
253 -```  
254 -  
255 -## axios API  
256 -  
257 -Requests can be made by passing the relevant config to `axios`.  
258 -  
259 -##### axios(config)  
260 -  
261 -```js  
262 -// Send a POST request  
263 -axios({  
264 - method: 'post',  
265 - url: '/user/12345',  
266 - data: {  
267 - firstName: 'Fred',  
268 - lastName: 'Flintstone'  
269 - }  
270 -});  
271 -```  
272 -  
273 -```js  
274 -// GET request for remote image in node.js  
275 -axios({  
276 - method: 'get',  
277 - url: 'https://bit.ly/2mTM3nY',  
278 - responseType: 'stream'  
279 -})  
280 - .then(function (response) {  
281 - response.data.pipe(fs.createWriteStream('ada_lovelace.jpg'))  
282 - });  
283 -```  
284 -  
285 -##### axios(url[, config])  
286 -  
287 -```js  
288 -// Send a GET request (default method)  
289 -axios('/user/12345');  
290 -```  
291 -  
292 -### Request method aliases  
293 -  
294 -For convenience, aliases have been provided for all common request methods.  
295 -  
296 -##### axios.request(config)  
297 -##### axios.get(url[, config])  
298 -##### axios.delete(url[, config])  
299 -##### axios.head(url[, config])  
300 -##### axios.options(url[, config])  
301 -##### axios.post(url[, data[, config]])  
302 -##### axios.put(url[, data[, config]])  
303 -##### axios.patch(url[, data[, config]])  
304 -  
305 -###### NOTE  
306 -When using the alias methods `url`, `method`, and `data` properties don't need to be specified in config.  
307 -  
308 -### Concurrency (Deprecated)  
309 -Please use `Promise.all` to replace the below functions.  
310 -  
311 -Helper functions for dealing with concurrent requests.  
312 -  
313 -axios.all(iterable)  
314 -axios.spread(callback)  
315 -  
316 -### Creating an instance  
317 -  
318 -You can create a new instance of axios with a custom config.  
319 -  
320 -##### axios.create([config])  
321 -  
322 -```js  
323 -const instance = axios.create({  
324 - baseURL: 'https://some-domain.com/api/',  
325 - timeout: 1000,  
326 - headers: {'X-Custom-Header': 'foobar'}  
327 -});  
328 -```  
329 -  
330 -### Instance methods  
331 -  
332 -The available instance methods are listed below. The specified config will be merged with the instance config.  
333 -  
334 -##### axios#request(config)  
335 -##### axios#get(url[, config])  
336 -##### axios#delete(url[, config])  
337 -##### axios#head(url[, config])  
338 -##### axios#options(url[, config])  
339 -##### axios#post(url[, data[, config]])  
340 -##### axios#put(url[, data[, config]])  
341 -##### axios#patch(url[, data[, config]])  
342 -##### axios#getUri([config])  
343 -  
344 -## Request Config  
345 -  
346 -These are the available config options for making requests. Only the `url` is required. Requests will default to `GET` if `method` is not specified.  
347 -  
348 -```js  
349 -{  
350 - // `url` is the server URL that will be used for the request  
351 - url: '/user',  
352 -  
353 - // `method` is the request method to be used when making the request  
354 - method: 'get', // default  
355 -  
356 - // `baseURL` will be prepended to `url` unless `url` is absolute.

358 - // to methods of that instance.  
359 - baseURL: 'https://some-domain.com/api/',  
360 -  
361 - // `transformRequest` allows changes to the request data before it is sent to the server

590 -}  
591 -```  
592 -  
593 -## Response Schema  
594 -  
595 -The response for a request contains the following information.  
596 -  
597 -```js  
598 -{  
599 - // `data` is the response that was provided by the server  
600 - data: {},  
601 -  
602 - // `status` is the HTTP status code from the server response  
603 - status: 200,  
604 -  
605 - // `statusText` is the HTTP status message from the server response  
606 - statusText: 'OK',  
607 -  
608 - // `headers` the HTTP headers that the server responded with  
609 - // All header names are lowercase and can be accessed using the bracket notation.  
610 - // Example: `response.headers['content-type']`  
611 - headers: {},  
612 -  
613 - // `config` is the config that was provided to `axios` for the request  
614 - config: {},  
615 -  
616 - // `request` is the request that generated this response  
617 - // It is the last ClientRequest instance in node.js (in redirects)  
618 - // and an XMLHttpRequest instance in the browser  
619 - request: {}  
620 -}  
621 -```  
622 -  
623 -When using `then`, you will receive the response as follows:  
624 -  
625 -```js  
626 -axios.get('/user/12345')  
627 - .then(function (response) {  
628 - console.log(response.data);  
629 - console.log(response.status);  
630 - console.log(response.statusText);  
631 - console.log(response.headers);  
632 - console.log(response.config);  
633 - });  
634 -```  
635 -  
636 -When using `catch`, or passing a [rejection callback](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then) as second parameter of `then`, the response will be available through the `error` object as explained in the [Handling Errors](#handling-errors) section.  
637 -  
638 -## Config Defaults  
639 -  
640 -You can specify config defaults that will be applied to every request.  
641 -  
642 -### Global axios defaults  
643 -  
644 -```js  
645 -axios.defaults.baseURL = 'https://api.example.com';  
646 -  
647 -// Important: If axios is used with multiple domains, the AUTH_TOKEN will be sent to all of them.  
648 -// See below for an example using Custom instance defaults instead.  
649 -axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;  
650 -  
651 -axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';  
652 -```  
653 -  
654 -### Custom instance defaults  
655 -  
656 -```js  
657 -// Set config defaults when creating the instance  
658 -const instance = axios.create({  
659 - baseURL: 'https://api.example.com'  
660 -});  
661 -  
662 -// Alter defaults after instance has been created  
663 -instance.defaults.headers.common['Authorization'] = AUTH_TOKEN;  
664 -```  
665 -  
666 -### Config order of precedence  
667 -  
668 -Config will be merged with an order of precedence. The order is library defaults found in [lib/defaults.js](https://github.com/axios/axios/blob/master/lib/defaults/index.js#L28), then `defaults` property of the instance, and finally `config` argument for the request. The latter will take precedence over the former. Here's an example.  
669 -  
670 -```js  
671 -// Create an instance using the config defaults provided by the library  
672 -// At this point the timeout config value is `0` as is the default for the library  
673 -const instance = axios.create();  
674 -  
675 -// Override timeout default for the library  
676 -// Now all requests using this instance will wait 2.5 seconds before timing out  
677 -instance.defaults.timeout = 2500;  
678 -  
679 -// Override timeout for this request as it's known to take a long time  
680 -instance.get('/longRequest', {  
681 - timeout: 5000  
682 -});  
683 -```  
684 -  
685 -## Interceptors  
686 -  
687 -You can intercept requests or responses before they are handled by `then` or `catch`.  
688 -  
689 -```js  
690 -// Add a request interceptor  
691 -axios.interceptors.request.use(function (config) {  
692 - // Do something before request is sent  
693 - return config;  
694 - }, function (error) {  
695 - // Do something with request error  
696 - return Promise.reject(error);  
697 - });  
698 -  
699 -// Add a response interceptor  
700 -axios.interceptors.response.use(function (response) {  
701 - // Any status code that lie within the range of 2xx cause this function to trigger  
702 - // Do something with response data  
703 - return response;  
704 - }, function (error) {  
705 - // Any status codes that falls outside the range of 2xx cause this function to trigger  
706 - // Do something with response error  
707 - return Promise.reject(error);  
708 - });  
709 -```  
710 -  
711 -If you need to remove an interceptor later you can.  
712 -  
713 -```js  
714 -const myInterceptor = axios.interceptors.request.use(function () {/*...*/});  
715 -axios.interceptors.request.eject(myInterceptor);  
716 -```  
717 -  
718 -You can also clear all interceptors for requests or responses.  
719 -```js  
720 -const instance = axios.create();  
721 -instance.interceptors.request.use(function () {/*...*/});  
722 -instance.interceptors.request.clear(); // Removes interceptors from requests  
723 -instance.interceptors.response.use(function () {/*...*/});  
724 -instance.interceptors.response.clear(); // Removes interceptors from responses  
725 -```  
726 -  
727 -You can add interceptors to a custom instance of axios.  
728 -  
729 -```js  
730 -const instance = axios.create();  
731 -instance.interceptors.request.use(function () {/*...*/});  
732 -```  
733 -  
734 -When you add request interceptors, they are presumed to be asynchronous by default. This can cause a delay  
735 -in the execution of your axios request when the main thread is blocked (a promise is created under the hood for  
736 -the interceptor and your request gets put on the bottom of the call stack). If your request interceptors are synchronous you can add a flag  
737 -to the options object that will tell axios to run the code synchronously and avoid any delays in request execution.  
738 -  
739 -```js  
740 -axios.interceptors.request.use(function (config) {  
741 - config.headers.test = 'I am only a header!';  
742 - return config;  
743 -}, null, { synchronous: true });  
744 -```  
745 -  
746 -If you want to execute a particular interceptor based on a runtime check,  
747 -you can add a `runWhen` function to the options object. The interceptor will not be executed **if and only if** the return  
748 -of `runWhen` is `false`. The function will be called with the config  
749 -object (don't forget that you can bind your own arguments to it as well.) This can be handy when you have an  
750 -asynchronous request interceptor that only needs to run at certain times.  
751 -  
752 -```js  
753 -function onGetCall(config) {  
754 - return config.method === 'get';  
755 -}  
756 -axios.interceptors.request.use(function (config) {  
757 - config.headers.test = 'special get headers';  
758 - return config;  
759 -}, null, { runWhen: onGetCall });  
760 -```  
761 -  
762 -### Multiple Interceptors  
763 -  
764 -Given you add multiple response interceptors  
765 -and when the response was fulfilled  
766 -- then each interceptor is executed  
767 -- then they are executed in the order they were added  
768 -- then only the last interceptor's result is returned  
769 -- then every interceptor receives the result of its predecessor  
770 -- and when the fulfillment-interceptor throws  
771 - - then the following fulfillment-interceptor is not called  
772 - - then the following rejection-interceptor is called  
773 - - once caught, another following fulfill-interceptor is called again (just like in a promise chain).  
774 -  
775 -Read [the interceptor tests](./test/specs/interceptors.spec.js) for seeing all this in code.  
776 -  
777 -## Error Types  
778 -  
779 -There are many different axios error messages that can appear that can provide basic information about the specifics of the error and where opportunities may lie in debugging.  
780 -  
781 -The general structure of axios errors is as follows:  
782 -| Property | Definition |  
783 -| -------- | ---------- |  
784 -| message | A quick summary of the error message and the status it failed with. |  
785 -| name | This defines where the error originated from. For axios, it will always be an 'AxiosError'. |  
786 -| stack | Provides the stack trace of the error. |  
787 -| config | An axios config object with specific instance configurations defined by the user from when the request was made |  
788 -| code | Represents an axios identified error. The table below lists out specific definitions for internal axios error. |  
789 -| status | HTTP response status code. See [here](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes) for common HTTP response status code meanings.  
790 -  
791 -Below is a list of potential axios identified error  
792 -| Code | Definition |  
793 -| -------- | ---------- |  
794 -| ERR_BAD_OPTION_VALUE | Invalid or unsupported value provided in axios configuration. |  
795 -| ERR_BAD_OPTION | Invalid option provided in axios configuration. |  
796 -| ECONNABORTED | Request timed out due to exceeding timeout specified in axios configuration. |  
797 -| ETIMEDOUT | Request timed out due to exceeding default axios timelimit. |  
798 -| ERR_NETWORK | Network-related issue.  
799 -| ERR_FR_TOO_MANY_REDIRECTS | Request is redirected too many times; exceeds max redirects specified in axios configuration.  
800 -| ERR_DEPRECATED | Deprecated feature or method used in axios.  
801 -| ERR_BAD_RESPONSE | Response cannot be parsed properly or is in an unexpected format.  
802 -| ERR_BAD_REQUEST | Requested has unexpected format or missing required parameters. |  
803 -| ERR_CANCELED | Feature or method is canceled explicitly by the user.  
804 -| ERR_NOT_SUPPORT | Feature or method not supported in the current axios environment.  
805 -| ERR_INVALID_URL | Invalid URL provided for axios request.  
806 -  
807 -## Handling Errors  
808 -  
809 -the default behavior is to reject every response that returns with a status code that falls out of the range of 2xx and treat it as an error.  
810 -  
811 -```js  
812 -axios.get('/user/12345')  
813 - .catch(function (error) {  
814 - if (error.response) {  
815 - // The request was made and the server responded with a status code  
816 - // that falls out of the range of 2xx  
817 - console.log(error.response.data);  
818 - console.log(error.response.status);  
819 - console.log(error.response.headers);  
820 - } else if (error.request) {  
821 - // The request was made but no response was received  
822 - // `error.request` is an instance of XMLHttpRequest in the browser and an instance of  
823 - // http.ClientRequest in node.js  
824 - console.log(error.request);  
825 - } else {  
826 - // Something happened in setting up the request that triggered an Error  
827 - console.log('Error', error.message);  
828 - }  
829 - console.log(error.config);  
830 - });  
831 -```  
832 -  
833 -Using the `validateStatus` config option, you can override the default condition (status >= 200 && status < 300) and define HTTP code(s) that should throw an error.  
834 -  
835 -```js  
836 -axios.get('/user/12345', {  
837 - validateStatus: function (status) {  
838 - return status < 500; // Resolve only if the status code is less than 500  
839 - }  
840 -})  
841 -```  
842 -  
843 -Using `toJSON` you get an object with more information about the HTTP error.  
844 -  
845 -```js  
846 -axios.get('/user/12345')  
847 - .catch(function (error) {  
848 - console.log(error.toJSON());  
849 - });  
850 -```  
851 -  
852 -## Cancellation  
853 -  
854 -### AbortController  
855 -  
856 -Starting from `v0.22.0` Axios supports AbortController to cancel requests in fetch API way:  
857 -  
858 -```js  
859 -const controller = new AbortController();  
860 -  
861 -axios.get('/foo/bar', {  
862 - signal: controller.signal  
863 -}).then(function(response) {  
864 - //...  
865 -});  
866 -// cancel the request  
867 -controller.abort()  
868 -```  
869 -  
870 -### CancelToken `👎deprecated`  
871 -  
872 -You can also cancel a request using a *CancelToken*.  
873 -  
874 -> The axios cancel token API is based on the withdrawn [cancellable promises proposal](https://github.com/tc39/proposal-cancelable-promises).  
875 -  
876 -> This API is deprecated since v0.22.0 and shouldn't be used in new projects  
877 -  
878 -You can create a cancel token using the `CancelToken.source` factory as shown below:  
879 -  
880 -```js  
881 -const CancelToken = axios.CancelToken;  
882 -const source = CancelToken.source();  
883 -  
884 -axios.get('/user/12345', {  
885 - cancelToken: source.token  
886 -}).catch(function (thrown) {  
887 - if (axios.isCancel(thrown)) {  
888 - console.log('Request canceled', thrown.message);  
889 - } else {  
890 - // handle error  
891 - }  
892 -});  
893 -  
894 -axios.post('/user/12345', {  
895 - name: 'new name'  
896 -}, {  
897 - cancelToken: source.token  
898 -})  
899 -  
900 -// cancel the request (the message parameter is optional)  
901 -source.cancel('Operation canceled by the user.');  
902 -```  
903 -  
904 -You can also create a cancel token by passing an executor function to the `CancelToken` constructor:  
905 -  
906 -```js  
907 -const CancelToken = axios.CancelToken;  
908 -let cancel;  
909 -  
910 -axios.get('/user/12345', {  
911 - cancelToken: new CancelToken(function executor(c) {  
912 - // An executor function receives a cancel function as a parameter  
913 - cancel = c;  
914 - })  
915 -});  
916 -  
917 -// cancel the request  
918 -cancel();  
919 -```  
920 -  
921 -> **Note:** you can cancel several requests with the same cancel token/abort controller.  
922 -> If a cancellation token is already cancelled at the moment of starting an Axios request, then the request is cancelled immediately, without any attempts to make a real request.  
923 -  
924 -> During the transition period, you can use both cancellation APIs, even for the same request:  
925 -  
926 -## Using `application/x-www-form-urlencoded` format  
927 -  
928 -### URLSearchParams  
929 -  
930 -By default, axios serializes JavaScript objects to `JSON`. To send data in the [`application/x-www-form-urlencoded` format](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST) instead, you can use the [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) API, which is [supported](http://www.caniuse.com/#feat=urlsearchparams) in the vast majority of browsers,and [ Node](https://nodejs.org/api/url.html#url_class_urlsearchparams) starting with v10 (released in 2018).  
931 -  
932 -```js  
933 -const params = new URLSearchParams({ foo: 'bar' });  
934 -params.append('extraparam', 'value');  
935 -axios.post('/foo', params);  
936 -```  
937 -  
938 -### Query string (Older browsers)  
939 -  
940 -For compatibility with very old browsers, there is a [polyfill](https://github.com/WebReflection/url-search-params) available (make sure to polyfill the global environment).  
941 -  
942 -Alternatively, you can encode data using the [`qs`](https://github.com/ljharb/qs) library:  
943 -  
944 -```js  
945 -const qs = require('qs');  
946 -axios.post('/foo', qs.stringify({ 'bar': 123 }));  
947 -```  
948 -  
949 -Or in another way (ES6),  
950 -  
951 -```js  
952 -import qs from 'qs';  
953 -const data = { 'bar': 123 };  
954 -const options = {  
955 - method: 'POST',  
956 - headers: { 'content-type': 'application/x-www-form-urlencoded' },  
957 - data: qs.stringify(data),  
958 - url,  
959 -};  
960 -axios(options);  
961 -```  
962 -  
963 -### Older Node.js versions  
964 -  
965 -For older Node.js engines, you can use the [`querystring`](https://nodejs.org/api/querystring.html) module as follows:  
966 -  
967 -```js  
968 -const querystring = require('querystring');  
969 -axios.post('https://something.com/', querystring.stringify({ foo: 'bar' }));  
970 -```  
971 -  
972 -You can also use the [`qs`](https://github.com/ljharb/qs) library.  
973 -  
974 -> **Note**: The `qs` library is preferable if you need to stringify nested objects, as the `querystring` method has [known issues](https://github.com/nodejs/node-v0.x-archive/issues/1665) with that use case.  
975 -  
976 -### 🆕 Automatic serialization to URLSearchParams  
977 -  
978 -Axios will automatically serialize the data object to urlencoded format if the content-type header is set to "application/x-www-form-urlencoded".  
979 -  
980 -```js  
981 -const data = {  
982 - x: 1,  
983 - arr: [1, 2, 3],  
984 - arr2: [1, [2], 3],  
985 - users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}],  
986 -};  
987 -  
988 -await axios.postForm('https://postman-echo.com/post', data,  
989 - {headers: {'content-type': 'application/x-www-form-urlencoded'}}  
990 -);  
991 -```  
992 -  
993 -The server will handle it as:  
994 -  
995 -```js  
996 - {  
997 - x: '1',  
998 - 'arr[]': [ '1', '2', '3' ],  
999 - 'arr2[0]': '1',  
1000 - 'arr2[1][0]': '2',  
1001 - 'arr2[2]': '3',  
1002 - 'arr3[]': [ '1', '2', '3' ],  
1003 - 'users[0][name]': 'Peter',  
1004 - 'users[0][surname]': 'griffin',  
1005 - 'users[1][name]': 'Thomas',  
1006 - 'users[1][surname]': 'Anderson'  
1007 - }  
1008 -````  
1009 -  
1010 -If your backend body-parser (like `body-parser` of `express.js`) supports nested objects decoding, you will get the same object on the server-side automatically  
1011 -  
1012 -```js  
1013 - var app = express();  
1014 -  
1015 - app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies  
1016 -  
1017 - app.post('/', function (req, res, next) {  
1018 - // echo body as JSON  
1019 - res.send(JSON.stringify(req.body));  
1020 - });  
1021 -  
1022 - server = app.listen(3000);  
1023 -```  
1024 -  
1025 -## Using `multipart/form-data` format  
1026 -  
1027 -### FormData  
1028 -  
1029 -To send the data as a `multipart/formdata` you need to pass a formData instance as a payload.  
1030 -Setting the `Content-Type` header is not required as Axios guesses it based on the payload type.  
1031 -  
1032 -```js  
1033 -const formData = new FormData();  
1034 -formData.append('foo', 'bar');  
1035 -  
1036 -axios.post('https://httpbin.org/post', formData);  
1037 -```  
1038 -  
1039 -In node.js, you can use the [`form-data`](https://github.com/form-data/form-data) library as follows:  
1040 -  
1041 -```js  
1042 -const FormData = require('form-data');  
1043 -  
1044 -const form = new FormData();  
1045 -form.append('my_field', 'my value');  
1046 -form.append('my_buffer', new Buffer(10));  
1047 -form.append('my_file', fs.createReadStream('/foo/bar.jpg'));  
1048 -  
1049 -axios.post('https://example.com', form)  
1050 -```  
1051 -  
1052 -### 🆕 Automatic serialization to FormData  
1053 -  
1054 -Starting from `v0.27.0`, Axios supports automatic object serialization to a FormData object if the request `Content-Type`  
1055 -header is set to `multipart/form-data`.  
1056 -  
1057 -The following request will submit the data in a FormData format (Browser & Node.js):  
1058 -  
1059 -```js  
1060 -import axios from 'axios';  
1061 -  
1062 -axios.post('https://httpbin.org/post', {x: 1}, {  
1063 - headers: {  
1064 - 'Content-Type': 'multipart/form-data'  
1065 - }  
1066 -}).then(({data}) => console.log(data));  
1067 -```  
1068 -  
1069 -In the `node.js` build, the ([`form-data`](https://github.com/form-data/form-data)) polyfill is used by default.  
1070 -  
1071 -You can overload the FormData class by setting the `env.FormData` config variable,  
1072 -but you probably won't need it in most cases:  
1073 -  
1074 -```js  
1075 -const axios = require('axios');  
1076 -var FormData = require('form-data');  
1077 -  
1078 -axios.post('https://httpbin.org/post', {x: 1, buf: new Buffer(10)}, {  
1079 - headers: {  
1080 - 'Content-Type': 'multipart/form-data'  
1081 - }  
1082 -}).then(({data}) => console.log(data));  
1083 -```  
1084 -  
1085 -Axios FormData serializer supports some special endings to perform the following operations:  
1086 -  
1087 -- `{}` - serialize the value with JSON.stringify  
1088 -- `[]` - unwrap the array-like object as separate fields with the same key  
1089 -  
1090 -> **Note**: unwrap/expand operation will be used by default on arrays and FileList objects  
1091 -  
1092 -FormData serializer supports additional options via `config.formSerializer: object` property to handle rare cases:  
1093 -  
1094 -- `visitor: Function` - user-defined visitor function that will be called recursively to serialize the data object  
1095 -to a `FormData` object by following custom rules.  
1096 -  
1097 -- `dots: boolean = false` - use dot notation instead of brackets to serialize arrays and objects;  
1098 -  
1099 -- `metaTokens: boolean = true` - add the special ending (e.g `user{}: '{"name": "John"}'`) in the FormData key.  
1100 -The back-end body-parser could potentially use this meta-information to automatically parse the value as JSON.  
1101 -  
1102 -- `indexes: null|false|true = false` - controls how indexes will be added to unwrapped keys of `flat` array-like objects  
1103 -  
1104 - - `null` - don't add brackets (`arr: 1`, `arr: 2`, `arr: 3`)  
1105 - - `false`(default) - add empty brackets (`arr[]: 1`, `arr[]: 2`, `arr[]: 3`)  
1106 - - `true` - add brackets with indexes (`arr[0]: 1`, `arr[1]: 2`, `arr[2]: 3`)  
1107 -  
1108 -Let's say we have an object like this one:  
1109 -  
1110 -```js  
1111 -const obj = {  
1112 - x: 1,  
1113 - arr: [1, 2, 3],  
1114 - arr2: [1, [2], 3],  
1115 - users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}],  
1116 - 'obj2{}': [{x:1}]  
1117 -};  
1118 -```  
1119 -  
1120 -The following steps will be executed by the Axios serializer internally:  
1121 -  
1122 -```js  
1123 -const formData = new FormData();  
1124 -formData.append('x', '1');  
1125 -formData.append('arr[]', '1');  
1126 -formData.append('arr[]', '2');  
1127 -formData.append('arr[]', '3');  
1128 -formData.append('arr2[0]', '1');  
1129 -formData.append('arr2[1][0]', '2');  
1130 -formData.append('arr2[2]', '3');  
1131 -formData.append('users[0][name]', 'Peter');  
1132 -formData.append('users[0][surname]', 'Griffin');  
1133 -formData.append('users[1][name]', 'Thomas');  
1134 -formData.append('users[1][surname]', 'Anderson');  
1135 -formData.append('obj2{}', '[{"x":1}]');  
1136 -```  
1137 -  
1138 -Axios supports the following shortcut methods: `postForm`, `putForm`, `patchForm`  
1139 -which are just the corresponding http methods with the `Content-Type` header preset to `multipart/form-data`.  
1140 -  
1141 -## Files Posting  
1142 -  
1143 -You can easily submit a single file:  
1144 -  
1145 -```js  
1146 -await axios.postForm('https://httpbin.org/post', {  
1147 - 'myVar' : 'foo',  
1148 - 'file': document.querySelector('#fileInput').files[0]  
1149 -});  
1150 -```  
1151 -  
1152 -or multiple files as `multipart/form-data`:  
1153 -  
1154 -```js  
1155 -await axios.postForm('https://httpbin.org/post', {  
1156 - 'files[]': document.querySelector('#fileInput').files  
1157 -});  
1158 -```  
1159 -  
1160 -`FileList` object can be passed directly:  
1161 -  
1162 -```js  
1163 -await axios.postForm('https://httpbin.org/post', document.querySelector('#fileInput').files)  
1164 -```  
1165 -  
1166 -All files will be sent with the same field names: `files[]`.  
1167 -  
1168 -## 🆕 HTML Form Posting (browser)  
1169 -  
1170 -Pass HTML Form element as a payload to submit it as `multipart/form-data` content.  
1171 -  
1172 -```js  
1173 -await axios.postForm('https://httpbin.org/post', document.querySelector('#htmlForm'));  
1174 -```  
1175 -  
1176 -`FormData` and `HTMLForm` objects can also be posted as `JSON` by explicitly setting the `Content-Type` header to `application/json`:  
1177 -  
1178 -```js  
1179 -await axios.post('https://httpbin.org/post', document.querySelector('#htmlForm'), {  
1180 - headers: {  
1181 - 'Content-Type': 'application/json'  
1182 - }  
1183 -})  
1184 -```  
1185 -  
1186 -For example, the Form  
1187 -  
1188 -```html  
1189 -<form id="form">  
1190 - <input type="text" name="foo" value="1">  
1191 - <input type="text" name="deep.prop" value="2">  
1192 - <input type="text" name="deep prop spaced" value="3">  
1193 - <input type="text" name="baz" value="4">  
1194 - <input type="text" name="baz" value="5">  
1195 -  
1196 - <select name="user.age">  
1197 - <option value="value1">Value 1</option>  
1198 - <option value="value2" selected>Value 2</option>  
1199 - <option value="value3">Value 3</option>  
1200 - </select>  
1201 -  
1202 - <input type="submit" value="Save">  
1203 -</form>  
1204 -```  
1205 -  
1206 -will be submitted as the following JSON object:  
1207 -  
1208 -```js  
1209 -{  
1210 - "foo": "1",  
1211 - "deep": {  
1212 - "prop": {  
1213 - "spaced": "3"  
1214 - }  
1215 - },  
1216 - "baz": [  
1217 - "4",  
1218 - "5"  
1219 - ],  
1220 - "user": {  
1221 - "age": "value2"  
1222 - }  
1223 -}  
1224 -````  
1225 -  
1226 -Sending `Blobs`/`Files` as JSON (`base64`) is not currently supported.  
1227 -  
1228 -## 🆕 Progress capturing  
1229 -  
1230 -Axios supports both browser and node environments to capture request upload/download progress.  
1231 -  
1232 -```js  
1233 -await axios.post(url, data, {  
1234 - onUploadProgress: function (axiosProgressEvent) {  
1235 - /*{  
1236 - loaded: number;  
1237 - total?: number;  
1238 - progress?: number; // in range [0..1]  
1239 - bytes: number; // how many bytes have been transferred since the last trigger (delta)  
1240 - estimated?: number; // estimated time in seconds  
1241 - rate?: number; // upload speed in bytes  
1242 - upload: true; // upload sign  
1243 - }*/  
1244 - },  
1245 -  
1246 - onDownloadProgress: function (axiosProgressEvent) {  
1247 - /*{  
1248 - loaded: number;  
1249 - total?: number;  
1250 - progress?: number;  
1251 - bytes: number;  
1252 - estimated?: number;  
1253 - rate?: number; // download speed in bytes  
1254 - download: true; // download sign  
1255 - }*/  
1256 - }  
1257 -});  
1258 -```  
1259 -  
1260 -You can also track stream upload/download progress in node.js:  
1261 -  
1262 -```js  
1263 -const {data} = await axios.post(SERVER_URL, readableStream, {  
1264 - onUploadProgress: ({progress}) => {  
1265 - console.log((progress * 100).toFixed(2));  
1266 - },  
1267 -  
1268 - headers: {  
1269 - 'Content-Length': contentLength  
1270 - },  
1271 -  
1272 - maxRedirects: 0 // avoid buffering the entire stream  
1273 -});  
1274 -````  
1275 -  
1276 -> **Note:**  
1277 -> Capturing FormData upload progress is not currently supported in node.js environments.  
1278 -  
1279 -> **⚠️ Warning**  
1280 -> It is recommended to disable redirects by setting maxRedirects: 0 to upload the stream in the **node.js** environment,  
1281 -> as follow-redirects package will buffer the entire stream in RAM without following the "backpressure" algorithm.  
1282 -  
1283 -  
1284 -## 🆕 Rate limiting  
1285 -  
1286 -Download and upload rate limits can only be set for the http adapter (node.js):  
1287 -  
1288 -```js  
1289 -const {data} = await axios.post(LOCAL_SERVER_URL, myBuffer, {  
1290 - onUploadProgress: ({progress, rate}) => {  
1291 - console.log(`Upload [${(progress*100).toFixed(2)}%]: ${(rate / 1024).toFixed(2)}KB/s`)  
1292 - },  
1293 -  
1294 - maxRate: [100 * 1024], // 100KB/s limit  
1295 -});  
1296 -```  
1297 -  
1298 -## 🆕 AxiosHeaders  
1299 -  
1300 -Axios has its own `AxiosHeaders` class to manipulate headers using a Map-like API that guarantees caseless work.  
1301 -Although HTTP is case-insensitive in headers, Axios will retain the case of the original header for stylistic reasons  
1302 -and for a workaround when servers mistakenly consider the header's case.  
1303 -The old approach of directly manipulating headers object is still available, but deprecated and not recommended for future usage.  
1304 -  
1305 -### Working with headers  
1306 -  
1307 -An AxiosHeaders object instance can contain different types of internal values. that control setting and merging logic.  
1308 -The final headers object with string values is obtained by Axios by calling the `toJSON` method.  
1309 -  
1310 -> Note: By JSON here we mean an object consisting only of string values intended to be sent over the network.  
1311 -  
1312 -The header value can be one of the following types:  
1313 -- `string` - normal string value that will be sent to the server  
1314 -- `null` - skip header when rendering to JSON  
1315 -- `false` - skip header when rendering to JSON, additionally indicates that `set` method must be called with `rewrite` option set to `true`  
1316 - to overwrite this value (Axios uses this internally to allow users to opt out of installing certain headers like `User-Agent` or `Content-Type`)  
1317 -- `undefined` - value is not set  
1318 -  
1319 -> Note: The header value is considered set if it is not equal to undefined.  
1320 -  
1321 -The headers object is always initialized inside interceptors and transformers:  
1322 -  
1323 -```ts  
1324 - axios.interceptors.request.use((request: InternalAxiosRequestConfig) => {  
1325 - request.headers.set('My-header', 'value');  
1326 -  
1327 - request.headers.set({  
1328 - "My-set-header1": "my-set-value1",  
1329 - "My-set-header2": "my-set-value2"  
1330 - });  
1331 -  
1332 - request.headers.set('User-Agent', false); // disable subsequent setting the header by Axios  
1333 -  
1334 - request.headers.setContentType('text/plain');  
1335 -  
1336 - request.headers['My-set-header2'] = 'newValue' // direct access is deprecated  
1337 -  
1338 - return request;  
1339 - }  
1340 - );  
1341 -````  
1342 -  
1343 -You can iterate over an `AxiosHeaders` instance using a `for...of` statement:  
1344 -  
1345 -````js  
1346 -const headers = new AxiosHeaders({  
1347 - foo: '1',  
1348 - bar: '2',  
1349 - baz: '3'  
1350 -});  
1351 -  
1352 -for(const [header, value] of headers) {  
1353 - console.log(header, value);  
1354 -}  
1355 -  
1356 -// foo 1  
1357 -// bar 2  
1358 -// baz 3  
1359 -````  
1360 -  
1361 -### new AxiosHeaders(headers?)  
1362 -  
1363 -Constructs a new `AxiosHeaders` instance.  
1364 -  
1365 -```  
1366 -constructor(headers?: RawAxiosHeaders | AxiosHeaders | string);  
1367 -```  
1368 -  
1369 -If the headers object is a string, it will be parsed as RAW HTTP headers.  
1370 -  
1371 -````js  
1372 -const headers = new AxiosHeaders(`  
1373 -Host: www.bing.com  
1374 -User-Agent: curl/7.54.0  
1375 -Accept: */*`);  
1376 -  
1377 -console.log(headers);  
1378 -  
1379 -// Object [AxiosHeaders] {  
1380 -// host: 'www.bing.com',  
1381 -// 'user-agent': 'curl/7.54.0',  
1382 -// accept: '*/*'  
1383 -// }  
1384 -````  
1385 -  
1386 -### AxiosHeaders#set  
1387 -  
1388 -```ts  
1389 -set(headerName, value: Axios, rewrite?: boolean);  
1390 -set(headerName, value, rewrite?: (this: AxiosHeaders, value: string, name: string, headers: RawAxiosHeaders) => boolean);  
1391 -set(headers?: RawAxiosHeaders | AxiosHeaders | string, rewrite?: boolean);  
1392 -```  
1393 -  
1394 -The `rewrite` argument controls the overwriting behavior:  
1395 -- `false` - do not overwrite if header's value is set (is not `undefined`)  
1396 -- `undefined` (default) - overwrite the header unless its value is set to `false`  
1397 -- `true` - rewrite anyway  
1398 -  
1399 -The option can also accept a user-defined function that determines whether the value should be overwritten or not.  
1400 -  
1401 -Returns `this`.  
1402 -  
1403 -### AxiosHeaders#get(header)  
1404 -  
1405 -```  
1406 - get(headerName: string, matcher?: true | AxiosHeaderMatcher): AxiosHeaderValue;  
1407 - get(headerName: string, parser: RegExp): RegExpExecArray | null;  
1408 -````  
1409 -  
1410 -Returns the internal value of the header. It can take an extra argument to parse the header's value with `RegExp.exec`,  
1411 -matcher function or internal key-value parser.  
1412 -  
1413 -```ts  
1414 -const headers = new AxiosHeaders({

1437 -  
1438 -Returns the value of the header.  
1439 -  
1440 -### AxiosHeaders#has(header, matcher?)  
1441 -  
1442 -```  
1443 -has(header: string, matcher?: AxiosHeaderMatcher): boolean;  
1444 -```  
1445 -  
1446 -Returns `true` if the header is set (has no `undefined` value).  
1447 -  
1448 -### AxiosHeaders#delete(header, matcher?)  
1449 -  
1450 -```  
1451 -delete(header: string | string[], matcher?: AxiosHeaderMatcher): boolean;  
1452 -```  
1453 -  
1454 -Returns `true` if at least one header has been removed.  
1455 -  
1456 -### AxiosHeaders#clear(matcher?)  
1457 -  
1458 -```  
1459 -clear(matcher?: AxiosHeaderMatcher): boolean;  
1460 -```  
1461 -  
1462 -Removes all headers.  
1463 -Unlike the `delete` method matcher, this optional matcher will be used to match against the header name rather than the value.  
1464 -  
1465 -```ts  
1466 -const headers = new AxiosHeaders({  
1467 - 'foo': '1',  
1468 - 'x-foo': '2',  
1469 - 'x-bar': '3',  
1470 -});  
1471 -  
1472 -console.log(headers.clear(/^x-/)); // true  
1473 -  
1474 -console.log(headers.toJSON()); // [Object: null prototype] { foo: '1' }  
1475 -```  
1476 -  
1477 -Returns `true` if at least one header has been cleared.  
1478 -  
1479 -### AxiosHeaders#normalize(format);  
1480 -  
1481 -If the headers object was changed directly, it can have duplicates with the same name but in different cases.  
1482 -This method normalizes the headers object by combining duplicate keys into one.  
1483 -Axios uses this method internally after calling each interceptor.  
1484 -Set `format` to true for converting headers name to lowercase and capitalize the initial letters (`cOntEnt-type` => `Content-Type`)  
1485 -  
1486 -```js  
1487 -const headers = new AxiosHeaders({  
1488 - 'foo': '1',  
1489 -});  
1490 -  
1491 -headers.Foo = '2';  
1492 -headers.FOO = '3';  
1493 -  
1494 -console.log(headers.toJSON()); // [Object: null prototype] { foo: '1', Foo: '2', FOO: '3' }  
1495 -console.log(headers.normalize().toJSON()); // [Object: null prototype] { foo: '3' }  
1496 -console.log(headers.normalize(true).toJSON()); // [Object: null prototype] { Foo: '3' }  
1497 -```  
1498 -  
1499 -Returns `this`.  
1500 -  
1501 -### AxiosHeaders#concat(...targets)  
1502 -  
1503 -```  
1504 -concat(...targets: Array<AxiosHeaders | RawAxiosHeaders | string | undefined | null>): AxiosHeaders;  
1505 -```  
1506 -  
1507 -Merges the instance with targets into a new `AxiosHeaders` instance. If the target is a string, it will be parsed as RAW HTTP headers.  
1508 -  
1509 -Returns a new `AxiosHeaders` instance.  
1510 -  
1511 -### AxiosHeaders#toJSON(asStrings?)  
1512 -  
1513 -````  
1514 -toJSON(asStrings?: boolean): RawAxiosHeaders;  
1515 -````  
1516 -  
1517 -Resolve all internal headers values into a new null prototype object.  
1518 -Set `asStrings` to true to resolve arrays as a string containing all elements, separated by commas.  
1519 -  
1520 -### AxiosHeaders.from(thing?)  
1521 -  
1522 -````  
1523 -from(thing?: AxiosHeaders | RawAxiosHeaders | string): AxiosHeaders;  
1524 -````  
1525 -  
1526 -Returns a new `AxiosHeaders` instance created from the raw headers passed in,  
1527 -or simply returns the given headers object if it's an `AxiosHeaders` instance.  
1528 -  
1529 -### AxiosHeaders.concat(...targets)  
1530 -  
1531 -````  
1532 -concat(...targets: Array<AxiosHeaders | RawAxiosHeaders | string | undefined | null>): AxiosHeaders;  
1533 -````  
1534 -  
1535 -Returns a new `AxiosHeaders` instance created by merging the target objects.  
1536 -  
1537 -### Shortcuts

1552 -## Semver  
1553 -  
1554 -Until axios reaches a `1.0` release, breaking changes will be released with a new minor version. For example `0.5.1`, and `0.5.4` will have the same API, but `0.6.0` will have breaking changes.  
1555 -  
1556 -## Promises  
1557 -  
1558 -axios depends on a native ES6 Promise implementation to be [supported](https://caniuse.com/promises).  
1559 -If your environment doesn't support ES6 Promises, you can [polyfill](https://github.com/jakearchibald/es6-promise).  
1560 -  
1561 -## TypeScript  
1562 -  
1563 -axios includes [TypeScript](https://typescriptlang.org) definitions and a type guard for axios errors.  
1564 -  
1565 -```typescript  
1566 -let user: User = null;  
1567 -try {  
1568 - const { data } = await axios.get('/user?ID=12345');  
1569 - user = data.userDetails;  
1570 -} catch (error) {  
1571 - if (axios.isAxiosError(error)) {  
1572 - handleAxiosError(error);  
1573 - } else {  
1574 - handleUnexpectedError(error);  
1575 - }  
1576 -}  
1577 -```  
1578 -  
1579 -Because axios dual publishes with an ESM default export and a CJS `module.exports`, there are some caveats.  
1580 -The recommended setting is to use `"moduleResolution": "node16"` (this is implied by `"module": "node16"`). Note that this requires TypeScript 4.7 or greater.  
1581 -If use ESM, your settings should be fine.  
1582 -If you compile TypeScript to CJS and you can’t use `"moduleResolution": "node 16"`, you have to enable `esModuleInterop`.  
1583 -If you use TypeScript to type check CJS JavaScript code, your only option is to use `"moduleResolution": "node16"`.

1599 -## Credits  
1600 -  
1601 -axios is heavily inspired by the [$http service](https://docs.angularjs.org/api/ng/service/$http) provided in [AngularJS](https://angularjs.org/). Ultimately axios is an effort to provide a standalone `$http`-like service for use outside of AngularJS.
