-Using jsDelivr CDN:
+Using pnpm:
 
-```html
-<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
+```bash
+$ pnpm add axios
 ```
 
-Using unpkg CDN:
+Once the package is installed, you can import the library using `import` or `require` approach:
 
-```html
-<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
+```js
+import axios, {isCancel, AxiosError} from 'axios';
 ```
 
-## Example
+You can also use the default export, since the named export is just a re-export from the Axios factory:
 
-### note: CommonJS usage
-In order to gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with `require()` use the following approach:
+```js
+import axios from 'axios';
 
+console.log(axios.isCancel('something'));
+````
+
+If you use `require` for importing, **only default export is available**:
+
 ```js
-const axios = require('axios').default;
+const axios = require('axios');
 
-// axios.<method> will now provide autocomplete and parameter typings
+console.log(axios.isCancel('something'));
 ```
 
-Performing a `GET` request
+For cases where something went wrong when trying to import a module into a custom or legacy environment,
+you can try importing the module package directly:
 
 ```js
-const axios = require('axios');
+const axios = require('axios/dist/browser/axios.cjs'); // browser commonJS bundle (ES2017)
+// const axios = require('axios/dist/node/axios.cjs'); // node commonJS bundle (ES2017)

+formData.append('foo', 'bar');
+
+axios.post('https://httpbin.org/post', formData);
+```

-Alternatively, use an interceptor:
+### 🆕 Automatic serialization to FormData
 
+Starting from `v0.27.0`, Axios supports automatic object serialization to a FormData object if the request `Content-Type`
+header is set to `multipart/form-data`.
+
+The following request will submit the data in a FormData format (Browser & Node.js):
+
 ```js
-axios.interceptors.request.use(config => {
-  if (config.data instanceof FormData) {
-    Object.assign(config.headers, config.data.getHeaders());
+import axios from 'axios';
+
+axios.post('https://httpbin.org/post', {x: 1}, {
+  headers: {
+    'Content-Type': 'multipart/form-data'
   }
-  return config;
+}).then(({data}) => console.log(data));
+```
+
+In the `node.js` build, the ([`form-data`](https://github.com/form-data/form-data)) polyfill is used by default.
+
+You can overload the FormData class by setting the `env.FormData` config variable,
+but you probably won't need it in most cases:
+
+```js
+const axios = require('axios');
+var FormData = require('form-data');
+
+axios.post('https://httpbin.org/post', {x: 1, buf: new Buffer(10)}, {
+  headers: {
+    'Content-Type': 'multipart/form-data'
+  }
+}).then(({data}) => console.log(data));
+```
+
+Axios FormData serializer supports some special endings to perform the following operations:
+
+- `{}` - serialize the value with JSON.stringify
+- `[]` - unwrap the array-like object as separate fields with the same key
+
+> **Note**
+> unwrap/expand operation will be used by default on arrays and FileList objects
+
+FormData serializer supports additional options via `config.formSerializer: object` property to handle rare cases:
+
+- `visitor: Function` - user-defined visitor function that will be called recursively to serialize the data object
+to a `FormData` object by following custom rules.
+
+- `dots: boolean = false` - use dot notation instead of brackets to serialize arrays and objects;
+
+- `metaTokens: boolean = true` - add the special ending (e.g `user{}: '{"name": "John"}'`) in the FormData key.
+The back-end body-parser could potentially use this meta-information to automatically parse the value as JSON.
+
+- `indexes: null|false|true = false` - controls how indexes will be added to unwrapped keys of `flat` array-like objects
+
+    - `null` - don't add brackets (`arr: 1`, `arr: 2`, `arr: 3`)
+    - `false`(default) - add empty brackets (`arr[]: 1`, `arr[]: 2`, `arr[]: 3`)
+    - `true` - add brackets with indexes  (`arr[0]: 1`, `arr[1]: 2`, `arr[2]: 3`)
+
+Let's say we have an object like this one:
+
+```js
+const obj = {
+  x: 1,
+  arr: [1, 2, 3],
+  arr2: [1, [2], 3],
+  users: [{name: 'Peter', surname: 'Griffin'}, {name: 'Thomas', surname: 'Anderson'}],
+  'obj2{}': [{x:1}]
+};
+```
+
+The following steps will be executed by the Axios serializer internally:
+
+```js
+const formData = new FormData();
+formData.append('x', '1');
+formData.append('arr[]', '1');
+formData.append('arr[]', '2');
+formData.append('arr[]', '3');
+formData.append('arr2[0]', '1');
+formData.append('arr2[1][0]', '2');
+formData.append('arr2[2]', '3');
+formData.append('users[0][name]', 'Peter');
+formData.append('users[0][surname]', 'Griffin');
+formData.append('users[1][name]', 'Thomas');
+formData.append('users[1][surname]', 'Anderson');
+formData.append('obj2{}', '[{"x":1}]');
+```
+
+Axios supports the following shortcut methods: `postForm`, `putForm`, `patchForm`
+which are just the corresponding http methods with the `Content-Type` header preset to `multipart/form-data`.
+
+## Files Posting
+
+You can easily submit a single file:
+
+```js
+await axios.postForm('https://httpbin.org/post', {
+  'myVar' : 'foo',
+  'file': document.querySelector('#fileInput').files[0]
 });
 ```
 
+or multiple files as `multipart/form-data`:
+
+```js
+await axios.postForm('https://httpbin.org/post', {
+  'files[]': document.querySelector('#fileInput').files
+});
+```
+
+`FileList` object can be passed directly:
+
+```js
+await axios.postForm('https://httpbin.org/post', document.querySelector('#fileInput').files)
+```
+
+All files will be sent with the same field names: `files[]`.
+
+## 🆕 HTML Form Posting (browser)
+
+Pass HTML Form element as a payload to submit it as `multipart/form-data` content.
+
+```js
+await axios.postForm('https://httpbin.org/post', document.querySelector('#htmlForm'));
+```
+
+`FormData` and `HTMLForm` objects can also be posted as `JSON` by explicitly setting the `Content-Type` header to `application/json`:
+
+```js
+await axios.post('https://httpbin.org/post', document.querySelector('#htmlForm'), {
+  headers: {
+    'Content-Type': 'application/json'
+  }
+})
+```
+
+For example, the Form
+
+```html
+<form id="form">
+  <input type="text" name="foo" value="1">
+  <input type="text" name="deep.prop" value="2">
+  <input type="text" name="deep prop spaced" value="3">
+  <input type="text" name="baz" value="4">
+  <input type="text" name="baz" value="5">
+
+  <select name="user.age">
+    <option value="value1">Value 1</option>
+    <option value="value2" selected>Value 2</option>
+    <option value="value3">Value 3</option>
+  </select>
+
+  <input type="submit" value="Save">
+</form>
+```
+
+will be submitted as the following JSON object:
+
+```js
+{
+  "foo": "1",
+  "deep": {
+    "prop": {
+      "spaced": "3"
+    }
+  },
+  "baz": [
+    "4",
+    "5"
+  ],
+  "user": {
+    "age": "value2"
+  }
+}

+    }*/
+  }
+});  
+```
+
+You can also track stream upload/download progress in node.js:
+
+```js
+const {data} = await axios.post(SERVER_URL, readableStream, {
+   onUploadProgress: ({progress}) => {
+     console.log((progress * 100).toFixed(2));
+   },
+  
+   headers: {
+    'Content-Length': contentLength
+   },
+
+   maxRedirects: 0 // avoid buffering the entire stream
+});
+````
+
+> **Note:**
+> Capturing FormData upload progress is currently not currently supported in node.js environments.
+
+> **⚠️ Warning**
+> It is recommended to disable redirects by setting maxRedirects: 0 to upload the stream in the **node.js** environment,
+> as follow-redirects package will buffer the entire stream in RAM without following the "backpressure" algorithm.
+
+
+## 🆕 Rate limiting
+
+Download and upload rate limits can only be set for the http adapter (node.js):
+
+```js
+const {data} = await axios.post(LOCAL_SERVER_URL, myBuffer, {
+  onUploadProgress: ({progress, rate}) => {
+    console.log(`Upload [${(progress*100).toFixed(2)}%]: ${(rate / 1024).toFixed(2)}KB/s`)
+  },
+   
+  maxRate: [100 * 1024], // 100KB/s limit
+});
+```

+Because axios dual publishes with an ESM default export and a CJS `module.exports`, there are some caveats.
+The recommended setting is to use `"moduleResolution": "node16"` (this is implied by `"module": "node16"`). Note that this requires TypeScript 4.7 or greater.

UPGRADE_GUIDE.md

-# Upgrade Guide
-
-### 0.15.x -> 0.16.0
-
-#### `Promise` Type Declarations
-
-The `Promise` type declarations have been removed from the axios typings in favor of the built-in type declarations. If you use axios in a TypeScript project that targets `ES5`, please make sure to include the `es2015.promise` lib. Please see [this post](https://blog.mariusschulz.com/2016/11/25/typescript-2-0-built-in-type-declarations) for details.
-
-### 0.13.x -> 0.14.0
-
-#### TypeScript Definitions
-
-The axios TypeScript definitions have been updated to match the axios API and use the ES2015 module syntax.
-
-Please use the following `import` statement to import axios in TypeScript:
-
-```typescript
-import axios from 'axios';
-
-axios.get('/foo')
-  .then(response => console.log(response))
-  .catch(error => console.log(error));
-```
-
-#### `agent` Config Option
-
-The `agent` config option has been replaced with two new options: `httpAgent` and `httpsAgent`. Please use them instead.
-
-```js
-{
-  // Define a custom agent for HTTP
-  httpAgent: new http.Agent({ keepAlive: true }),
-  // Define a custom agent for HTTPS
-  httpsAgent: new https.Agent({ keepAlive: true })
-}
-```
-
-#### `progress` Config Option
-
-The `progress` config option has been replaced with the `onUploadProgress` and `onDownloadProgress` options.
-
-```js
-{
-  // Define a handler for upload progress events
-  onUploadProgress: function (progressEvent) {
-    // ...
-  },
-
-  // Define a handler for download progress events
-  onDownloadProgress: function (progressEvent) {
-    // ...
-  }
-}
-```
-
-### 0.12.x -> 0.13.0
-
-The `0.13.0` release contains several changes to custom adapters and error handling.
-
-#### Error Handling
-
-Previous to this release an error could either be a server response with bad status code or an actual `Error`. With this release Promise will always reject with an `Error`. In the case that a response was received, the `Error` will also include the response.
-
-```js
-axios.get('/user/12345')
-  .catch((error) => {
-    console.log(error.message);
-    console.log(error.code); // Not always specified
-    console.log(error.config); // The config that was used to make the request
-    console.log(error.response); // Only available if response was received from the server
-  });
-```
-
-#### Request Adapters
-
-This release changes a few things about how request adapters work. Please take note if you are using your own custom adapter.
-
-1. Response transformer is now called outside of adapter.
-2. Request adapter returns a `Promise`.
-
-This means that you no longer need to invoke `transformData` on response data. You will also no longer receive `resolve` and `reject` as arguments in your adapter.
-
-Previous code:
-
-```js
-function myAdapter(resolve, reject, config) {
-  var response = {
-    data: transformData(
-      responseData,
-      responseHeaders,
-      config.transformResponse
-    ),
-    status: request.status,
-    statusText: request.statusText,
-    headers: responseHeaders
-  };
-  settle(resolve, reject, response);
-}
-```
-
-New code:
-
-```js
-function myAdapter(config) {
-  return new Promise(function (resolve, reject) {
-    var response = {
-      data: responseData,
-      status: request.status,
-      statusText: request.statusText,
-      headers: responseHeaders
-    };
-    settle(resolve, reject, response);
-  });
-}
-```
-
-See the related commits for more details:
-- [Response transformers](https://github.com/axios/axios/commit/10eb23865101f9347570552c04e9d6211376e25e)
-- [Request adapter Promise](https://github.com/axios/axios/commit/157efd5615890301824e3121cc6c9d2f9b21f94a)
-
-### 0.5.x -> 0.6.0
-
-The `0.6.0` release contains mostly bug fixes, but there are a couple things to be aware of when upgrading.
-
-#### ES6 Promise Polyfill
-
-Up until the `0.6.0` release ES6 `Promise` was being polyfilled using [es6-promise](https://github.com/jakearchibald/es6-promise). With this release, the polyfill has been removed, and you will need to supply it yourself if your environment needs it.
-
-```js
-require('es6-promise').polyfill();
-var axios = require('axios');
-```
-
-This will polyfill the global environment, and only needs to be done once.
-
-#### `axios.success`/`axios.error`
-
-The `success`, and `error` aliases were deprecated in [0.4.0](https://github.com/axios/axios/blob/master/CHANGELOG.md#040-oct-03-2014). As of this release they have been removed entirely. Instead please use `axios.then`, and `axios.catch` respectively.
-
-```js
-axios.get('some/url')
-  .then(function (res) {
-    /* ... */
-  })
-  .catch(function (err) {
-    /* ... */
-  });
-```
-
-#### UMD
-
-Previous versions of axios shipped with an AMD, CommonJS, and Global build. This has all been rolled into a single UMD build.
-
-```js
-// AMD
-require(['bower_components/axios/dist/axios'], function (axios) {
-  /* ... */
-});
-
-// CommonJS
-var axios = require('axios/dist/axios');
-```
