-## Installing
-
-Using npm:
-
-```bash
-$ npm install axios
-```
-
-Using bower:
-
-```bash
-$ bower install axios
-```
-
-Using yarn:
-
-```bash
-$ yarn add axios
-```
-
-Using jsDelivr CDN:
-
-```html
-<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
-```
-
-Using unpkg CDN:
-
-```html
-<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
-```
-
-## Example
-
-### note: CommonJS usage
-In order to gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with `require()` use the following approach:
-
-```js
-const axios = require('axios').default;
-
-// axios.<method> will now provide autocomplete and parameter typings
-```
-
-Performing a `GET` request
-
-```js
-const axios = require('axios');
-
-// Make a request for a user with a given ID
-axios.get('/user?ID=12345')
-  .then(function (response) {
-    // handle success
-    console.log(response);
-  })
-  .catch(function (error) {
-    // handle error
-    console.log(error);
-  })
-  .then(function () {
-    // always executed
-  });
-
-// Optionally the request above could also be done as
-axios.get('/user', {
-    params: {
-      ID: 12345
-    }
-  })
-  .then(function (response) {
-    console.log(response);
-  })
-  .catch(function (error) {
-    console.log(error);
-  })
-  .then(function () {
-    // always executed
-  });  
-
-// Want to use async/await? Add the `async` keyword to your outer function/method.
-async function getUser() {
-  try {
-    const response = await axios.get('/user?ID=12345');
-    console.log(response);
-  } catch (error) {
-    console.error(error);
-  }
-}
-```
-
-> **NOTE:** `async/await` is part of ECMAScript 2017 and is not supported in Internet
-> Explorer and older browsers, so use with caution.
-
-Performing a `POST` request
-
-```js
-axios.post('/user', {
-    firstName: 'Fred',
-    lastName: 'Flintstone'
-  })
-  .then(function (response) {
-    console.log(response);
-  })
-  .catch(function (error) {
-    console.log(error);
-  });
-```
-
-Performing multiple concurrent requests
-
-```js
-function getUserAccount() {
-  return axios.get('/user/12345');
-}
-
-function getUserPermissions() {
-  return axios.get('/user/12345/permissions');
-}
-
-Promise.all([getUserAccount(), getUserPermissions()])
-  .then(function (results) {
-    const acct = results[0];
-    const perm = results[1];
-  });
-```
-
-## axios API
-
-Requests can be made by passing the relevant config to `axios`.
-
-##### axios(config)
-
-```js
-// Send a POST request
-axios({
-  method: 'post',
-  url: '/user/12345',
-  data: {
-    firstName: 'Fred',
-    lastName: 'Flintstone'
-  }
-});
-```
-
-```js
-// GET request for remote image in node.js
-axios({
-  method: 'get',
-  url: 'http://bit.ly/2mTM3nY',
-  responseType: 'stream'
-})
-  .then(function (response) {
-    response.data.pipe(fs.createWriteStream('ada_lovelace.jpg'))
-  });
-```
-
-##### axios(url[, config])
-
-```js
-// Send a GET request (default method)
-axios('/user/12345');
-```
-
-### Request method aliases
-
-For convenience aliases have been provided for all supported request methods.
-
-##### axios.request(config)
-##### axios.get(url[, config])
-##### axios.delete(url[, config])
-##### axios.head(url[, config])
-##### axios.options(url[, config])
-##### axios.post(url[, data[, config]])
-##### axios.put(url[, data[, config]])
-##### axios.patch(url[, data[, config]])
-
-###### NOTE
-When using the alias methods `url`, `method`, and `data` properties don't need to be specified in config.
-
-### Concurrency (Deprecated)
-Please use `Promise.all` to replace the below functions.
-
-Helper functions for dealing with concurrent requests.
-
-axios.all(iterable)
-axios.spread(callback)
-
-### Creating an instance
-
-You can create a new instance of axios with a custom config.
-
-##### axios.create([config])
-
-```js
-const instance = axios.create({
-  baseURL: 'https://some-domain.com/api/',
-  timeout: 1000,
-  headers: {'X-Custom-Header': 'foobar'}
-});
-```
-
-### Instance methods
-
-The available instance methods are listed below. The specified config will be merged with the instance config.
-
-##### axios#request(config)
-##### axios#get(url[, config])
-##### axios#delete(url[, config])
-##### axios#head(url[, config])
-##### axios#options(url[, config])
-##### axios#post(url[, data[, config]])
-##### axios#put(url[, data[, config]])
-##### axios#patch(url[, data[, config]])
-##### axios#getUri([config])
-
-## Request Config
-
-These are the available config options for making requests. Only the `url` is required. Requests will default to `GET` if `method` is not specified.
-
-```js
-{
-  // `url` is the server URL that will be used for the request
-  url: '/user',
-
-  // `method` is the request method to be used when making the request
-  method: 'get', // default
-
-  // `baseURL` will be prepended to `url` unless `url` is absolute.
-  // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
-  // to methods of that instance.
-  baseURL: 'https://some-domain.com/api/',
-
-  // `transformRequest` allows changes to the request data before it is sent to the server
-  // This is only applicable for request methods 'PUT', 'POST', 'PATCH' and 'DELETE'
-  // The last function in the array must return a string or an instance of Buffer, ArrayBuffer,
-  // FormData or Stream
-  // You may modify the headers object.
-  transformRequest: [function (data, headers) {
-    // Do whatever you want to transform the data
-
-    return data;
-  }],
-
-  // `transformResponse` allows changes to the response data to be made before
-  // it is passed to then/catch
-  transformResponse: [function (data) {
-    // Do whatever you want to transform the data
-
-    return data;
-  }],
-
-  // `headers` are custom headers to be sent
-  headers: {'X-Requested-With': 'XMLHttpRequest'},
-
-  // `params` are the URL parameters to be sent with the request
-  // Must be a plain object or a URLSearchParams object
-  params: {
-    ID: 12345
-  },
-
-  // `paramsSerializer` is an optional function in charge of serializing `params`
-  // (e.g. https://www.npmjs.com/package/qs, http://api.jquery.com/jquery.param/)
-  paramsSerializer: function (params) {
-    return Qs.stringify(params, {arrayFormat: 'brackets'})
-  },
-
-  // `data` is the data to be sent as the request body
-  // Only applicable for request methods 'PUT', 'POST', 'DELETE , and 'PATCH'
-  // When no `transformRequest` is set, must be of one of the following types:
-  // - string, plain object, ArrayBuffer, ArrayBufferView, URLSearchParams
-  // - Browser only: FormData, File, Blob
-  // - Node only: Stream, Buffer
-  data: {
-    firstName: 'Fred'
-  },
-  
-  // syntax alternative to send data into the body
-  // method post
-  // only the value is sent, not the key
-  data: 'Country=Brasil&City=Belo Horizonte',
-
-  // `timeout` specifies the number of milliseconds before the request times out.
-  // If the request takes longer than `timeout`, the request will be aborted.
-  timeout: 1000, // default is `0` (no timeout)
-
-  // `withCredentials` indicates whether or not cross-site Access-Control requests
-  // should be made using credentials
-  withCredentials: false, // default
-
-  // `adapter` allows custom handling of requests which makes testing easier.
-  // Return a promise and supply a valid response (see lib/adapters/README.md).
-  adapter: function (config) {
-    /* ... */
-  },
-
-  // `auth` indicates that HTTP Basic auth should be used, and supplies credentials.
-  // This will set an `Authorization` header, overwriting any existing
-  // `Authorization` custom headers you have set using `headers`.
-  // Please note that only HTTP Basic auth is configurable through this parameter.
-  // For Bearer tokens and such, use `Authorization` custom headers instead.
-  auth: {
-    username: 'janedoe',
-    password: 's00pers3cret'
-  },
-
-  // `responseType` indicates the type of data that the server will respond with
-  // options are: 'arraybuffer', 'document', 'json', 'text', 'stream'
-  //   browser only: 'blob'
-  responseType: 'json', // default
-
-  // `responseEncoding` indicates encoding to use for decoding responses (Node.js only)
-  // Note: Ignored for `responseType` of 'stream' or client-side requests
-  responseEncoding: 'utf8', // default
-
-  // `xsrfCookieName` is the name of the cookie to use as a value for xsrf token
-  xsrfCookieName: 'XSRF-TOKEN', // default
-
-  // `xsrfHeaderName` is the name of the http header that carries the xsrf token value
-  xsrfHeaderName: 'X-XSRF-TOKEN', // default
-
-  // `onUploadProgress` allows handling of progress events for uploads
-  // browser only
-  onUploadProgress: function (progressEvent) {
-    // Do whatever you want with the native progress event
-  },
-
-  // `onDownloadProgress` allows handling of progress events for downloads
-  // browser only
-  onDownloadProgress: function (progressEvent) {
-    // Do whatever you want with the native progress event
-  },
-
-  // `maxContentLength` defines the max size of the http response content in bytes allowed in node.js
-  maxContentLength: 2000,
-
-  // `maxBodyLength` (Node only option) defines the max size of the http request content in bytes allowed
-  maxBodyLength: 2000,
-
-  // `validateStatus` defines whether to resolve or reject the promise for a given
-  // HTTP response status code. If `validateStatus` returns `true` (or is set to `null`
-  // or `undefined`), the promise will be resolved; otherwise, the promise will be
-  // rejected.
-  validateStatus: function (status) {
-    return status >= 200 && status < 300; // default
-  },
-
-  // `maxRedirects` defines the maximum number of redirects to follow in node.js.
-  // If set to 0, no redirects will be followed.
-  maxRedirects: 5, // default
-
-  // `socketPath` defines a UNIX Socket to be used in node.js.
-  // e.g. '/var/run/docker.sock' to send requests to the docker daemon.
-  // Only either `socketPath` or `proxy` can be specified.
-  // If both are specified, `socketPath` is used.
-  socketPath: null, // default
-
-  // `httpAgent` and `httpsAgent` define a custom agent to be used when performing http
-  // and https requests, respectively, in node.js. This allows options to be added like
-  // `keepAlive` that are not enabled by default.
-  httpAgent: new http.Agent({ keepAlive: true }),
-  httpsAgent: new https.Agent({ keepAlive: true }),
-
-  // `proxy` defines the hostname, port, and protocol of the proxy server.
-  // You can also define your proxy using the conventional `http_proxy` and
-  // `https_proxy` environment variables. If you are using environment variables
-  // for your proxy configuration, you can also define a `no_proxy` environment
-  // variable as a comma-separated list of domains that should not be proxied.
-  // Use `false` to disable proxies, ignoring environment variables.
-  // `auth` indicates that HTTP Basic auth should be used to connect to the proxy, and
-  // supplies credentials.
-  // This will set an `Proxy-Authorization` header, overwriting any existing
-  // `Proxy-Authorization` custom headers you have set using `headers`.
-  // If the proxy server uses HTTPS, then you must set the protocol to `https`. 
-  proxy: {
-    protocol: 'https',
-    host: '127.0.0.1',
-    port: 9000,
-    auth: {
-      username: 'mikeymike',
-      password: 'rapunz3l'
-    }
-  },
-
-  // `cancelToken` specifies a cancel token that can be used to cancel the request
-  // (see Cancellation section below for details)
-  cancelToken: new CancelToken(function (cancel) {
-  }),
-
-  // an alternative way to cancel Axios requests using AbortController
-  signal: new AbortController().signal,
-
-  // `decompress` indicates whether or not the response body should be decompressed 
-  // automatically. If set to `true` will also remove the 'content-encoding' header 
-  // from the responses objects of all decompressed responses
-  // - Node only (XHR cannot turn off decompression)
-  decompress: true // default
-
-  // `insecureHTTPParser` boolean.
-  // Indicates where to use an insecure HTTP parser that accepts invalid HTTP headers.
-  // This may allow interoperability with non-conformant HTTP implementations.
-  // Using the insecure parser should be avoided.
-  // see options https://nodejs.org/dist/latest-v12.x/docs/api/http.html#http_http_request_url_options_callback
-  // see also https://nodejs.org/en/blog/vulnerability/february-2020-security-releases/#strict-http-header-parsing-none
-  insecureHTTPParser: undefined // default
-
-  // transitional options for backward compatibility that may be removed in the newer versions
-  transitional: {
-    // silent JSON parsing mode
-    // `true`  - ignore JSON parsing errors and set response.data to null if parsing failed (old behaviour)
-    // `false` - throw SyntaxError if JSON parsing failed (Note: responseType must be set to 'json')
-    silentJSONParsing: true, // default value for the current Axios version

-    forcedJSONParsing: true,
-    
-    // throw ETIMEDOUT error instead of generic ECONNABORTED on request timeouts
-    clarifyTimeoutError: false,
-  }
-}
-```
-
-## Response Schema
-
-The response for a request contains the following information.
-
-```js
-{
-  // `data` is the response that was provided by the server
-  data: {},
-
-  // `status` is the HTTP status code from the server response
-  status: 200,
-
-  // `statusText` is the HTTP status message from the server response
-  statusText: 'OK',
-
-  // `headers` the HTTP headers that the server responded with
-  // All header names are lower cased and can be accessed using the bracket notation.
-  // Example: `response.headers['content-type']`
-  headers: {},
-
-  // `config` is the config that was provided to `axios` for the request
-  config: {},
-
-  // `request` is the request that generated this response
-  // It is the last ClientRequest instance in node.js (in redirects)
-  // and an XMLHttpRequest instance in the browser
-  request: {}
-}
-```
-
-When using `then`, you will receive the response as follows:
-
-```js
-axios.get('/user/12345')
-  .then(function (response) {
-    console.log(response.data);
-    console.log(response.status);
-    console.log(response.statusText);
-    console.log(response.headers);
-    console.log(response.config);
-  });
-```
-
-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.
-
-## Config Defaults
-
-You can specify config defaults that will be applied to every request.
-
-### Global axios defaults
-
-```js
-axios.defaults.baseURL = 'https://api.example.com';
-
-// Important: If axios is used with multiple domains, the AUTH_TOKEN will be sent to all of them.
-// See below for an example using Custom instance defaults instead.
-axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;
-
-axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
-```
-
-### Custom instance defaults
-
-```js
-// Set config defaults when creating the instance
-const instance = axios.create({
-  baseURL: 'https://api.example.com'
-});
-
-// Alter defaults after instance has been created
-instance.defaults.headers.common['Authorization'] = AUTH_TOKEN;
-```
-
-### Config order of precedence
-
-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.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.
-
-```js
-// Create an instance using the config defaults provided by the library
-// At this point the timeout config value is `0` as is the default for the library
-const instance = axios.create();
-
-// Override timeout default for the library
-// Now all requests using this instance will wait 2.5 seconds before timing out
-instance.defaults.timeout = 2500;
-
-// Override timeout for this request as it's known to take a long time
-instance.get('/longRequest', {
-  timeout: 5000
-});
-```
-
-## Interceptors
-
-You can intercept requests or responses before they are handled by `then` or `catch`.
-
-```js
-// Add a request interceptor
-axios.interceptors.request.use(function (config) {
-    // Do something before request is sent
-    return config;
-  }, function (error) {
-    // Do something with request error
-    return Promise.reject(error);
-  });
-
-// Add a response interceptor
-axios.interceptors.response.use(function (response) {
-    // Any status code that lie within the range of 2xx cause this function to trigger
-    // Do something with response data
-    return response;
-  }, function (error) {
-    // Any status codes that falls outside the range of 2xx cause this function to trigger
-    // Do something with response error
-    return Promise.reject(error);
-  });
-```
-
-If you need to remove an interceptor later you can.
-
-```js
-const myInterceptor = axios.interceptors.request.use(function () {/*...*/});
-axios.interceptors.request.eject(myInterceptor);
-```
-
-You can add interceptors to a custom instance of axios.
-
-```js
-const instance = axios.create();
-instance.interceptors.request.use(function () {/*...*/});
-```
-
-When you add request interceptors, they are presumed to be asynchronous by default. This can cause a delay
-in the execution of your axios request when the main thread is blocked (a promise is created under the hood for 
-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
-to the options object that will tell axios to run the code synchronously and avoid any delays in request execution.
-
-```js
-axios.interceptors.request.use(function (config) {
-  config.headers.test = 'I am only a header!';
-  return config;
-}, null, { synchronous: true });
-```
-
-If you want to execute a particular interceptor based on a runtime check, 
-you can add a `runWhen` function to the options object. The interceptor will not be executed **if and only if** the return
-of `runWhen` is `false`. The function will be called with the config
-object (don't forget that you can bind your own arguments to it as well.) This can be handy when you have an
-asynchronous request interceptor that only needs to run at certain times.
-
-```js
-function onGetCall(config) {
-  return config.method === 'get';
-}
-axios.interceptors.request.use(function (config) {
-  config.headers.test = 'special get headers';
-  return config;
-}, null, { runWhen: onGetCall });
-```
-
-### Multiple Interceptors
-
-Given you add multiple response interceptors
-and when the response was fulfilled
-- then each interceptor is executed
-- then they are executed in the order they were added
-- then only the last interceptor's result is returned
-- then every interceptor receives the result of it's predecessor
-- and when the fulfillment-interceptor throws
-    - then the following fulfillment-interceptor is not called
-    - then the following rejection-interceptor is called
-    - once caught, another following fulfill-interceptor is called again (just like in a promise chain).
-    
-Read [the interceptor tests](./test/specs/interceptors.spec.js) for seeing all this in code.
-
-## Handling Errors
-
-```js
-axios.get('/user/12345')
-  .catch(function (error) {
-    if (error.response) {
-      // The request was made and the server responded with a status code
-      // that falls out of the range of 2xx
-      console.log(error.response.data);
-      console.log(error.response.status);
-      console.log(error.response.headers);
-    } else if (error.request) {
-      // The request was made but no response was received
-      // `error.request` is an instance of XMLHttpRequest in the browser and an instance of
-      // http.ClientRequest in node.js
-      console.log(error.request);
-    } else {
-      // Something happened in setting up the request that triggered an Error
-      console.log('Error', error.message);
-    }
-    console.log(error.config);
-  });
-```
-
-Using the `validateStatus` config option, you can define HTTP code(s) that should throw an error.
-
-```js
-axios.get('/user/12345', {
-  validateStatus: function (status) {
-    return status < 500; // Resolve only if the status code is less than 500
-  }
-})
-```
-
-Using `toJSON` you get an object with more information about the HTTP error.
-
-```js
-axios.get('/user/12345')
-  .catch(function (error) {
-    console.log(error.toJSON());
-  });
-```
-
-## Cancellation
-
-You can cancel a request using a *cancel token*.
-
-> The axios cancel token API is based on the withdrawn [cancelable promises proposal](https://github.com/tc39/proposal-cancelable-promises).
-
-You can create a cancel token using the `CancelToken.source` factory as shown below:
-
-```js
-const CancelToken = axios.CancelToken;
-const source = CancelToken.source();
-
-axios.get('/user/12345', {
-  cancelToken: source.token
-}).catch(function (thrown) {
-  if (axios.isCancel(thrown)) {
-    console.log('Request canceled', thrown.message);
-  } else {
-    // handle error
-  }
-});
-
-axios.post('/user/12345', {
-  name: 'new name'
-}, {
-  cancelToken: source.token
-})
-
-// cancel the request (the message parameter is optional)
-source.cancel('Operation canceled by the user.');
-```
-
-You can also create a cancel token by passing an executor function to the `CancelToken` constructor:
-
-```js
-const CancelToken = axios.CancelToken;
-let cancel;
-
-axios.get('/user/12345', {
-  cancelToken: new CancelToken(function executor(c) {
-    // An executor function receives a cancel function as a parameter
-    cancel = c;
-  })
-});
-
-// cancel the request
-cancel();
-```
-
-Axios supports AbortController to abort requests in [`fetch API`](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API#aborting_a_fetch) way:
-```js
-const controller = new AbortController();
-
-axios.get('/foo/bar', {
-   signal: controller.signal
-}).then(function(response) {
-   //...
-});
-// cancel the request
-controller.abort()
-```
-
-> Note: you can cancel several requests with the same cancel token/abort controller.
-> 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 real request.
-
-## Using application/x-www-form-urlencoded format
-
-By default, axios serializes JavaScript objects to `JSON`. To send data in the `application/x-www-form-urlencoded` format instead, you can use one of the following options.
-
-### Browser
-
-In a browser, you can use the [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) API as follows:
-
-```js
-const params = new URLSearchParams();
-params.append('param1', 'value1');
-params.append('param2', 'value2');
-axios.post('/foo', params);
-```
-
-> Note that `URLSearchParams` is not supported by all browsers (see [caniuse.com](http://www.caniuse.com/#feat=urlsearchparams)), but there is a [polyfill](https://github.com/WebReflection/url-search-params) available (make sure to polyfill the global environment).
-
-Alternatively, you can encode data using the [`qs`](https://github.com/ljharb/qs) library:
-
-```js
-const qs = require('qs');
-axios.post('/foo', qs.stringify({ 'bar': 123 }));
-```
-
-Or in another way (ES6),
-
-```js
-import qs from 'qs';
-const data = { 'bar': 123 };
-const options = {
-  method: 'POST',
-  headers: { 'content-type': 'application/x-www-form-urlencoded' },
-  data: qs.stringify(data),
-  url,
-};
-axios(options);
-```
-
-### Node.js
-
-#### Query string
-
-In node.js, you can use the [`querystring`](https://nodejs.org/api/querystring.html) module as follows:
-
-```js
-const querystring = require('querystring');
-axios.post('http://something.com/', querystring.stringify({ foo: 'bar' }));
-```
-
-or ['URLSearchParams'](https://nodejs.org/api/url.html#url_class_urlsearchparams) from ['url module'](https://nodejs.org/api/url.html) as follows:
-
-```js
-const url = require('url');
-const params = new url.URLSearchParams({ foo: 'bar' });
-axios.post('http://something.com/', params.toString());
-```
-
-You can also use the [`qs`](https://github.com/ljharb/qs) library.
-
-###### NOTE
-The `qs` library is preferable if you need to stringify nested objects, as the `querystring` method has known issues with that use case (https://github.com/nodejs/node-v0.x-archive/issues/1665).
-
-#### Form data
-
-In node.js, you can use the [`form-data`](https://github.com/form-data/form-data) library as follows:
-
-```js
-const FormData = require('form-data');
- 
-const form = new FormData();
-form.append('my_field', 'my value');
-form.append('my_buffer', new Buffer(10));
-form.append('my_file', fs.createReadStream('/foo/bar.jpg'));
-
-axios.post('https://example.com', form, { headers: form.getHeaders() })
-```
-
-Alternatively, use an interceptor:
-
-```js
-axios.interceptors.request.use(config => {
-  if (config.data instanceof FormData) {
-    Object.assign(config.headers, config.data.getHeaders());
-  }
-  return config;
-});
-```
-
-## Semver
-
-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.
-
-## Promises
-
-axios depends on a native ES6 Promise implementation to be [supported](http://caniuse.com/promises).
-If your environment doesn't support ES6 Promises, you can [polyfill](https://github.com/jakearchibald/es6-promise).
-
-## TypeScript
-
-axios includes [TypeScript](http://typescriptlang.org) definitions and a type guard for axios errors.
-
-```typescript
-let user: User = null;
-try {
-  const { data } = await axios.get('/user?ID=12345');
-  user = data.userDetails;
-} catch (error) {
-  if (axios.isAxiosError(error)) {
-    handleAxiosError(error);
-  } else {
-    handleUnexpectedError(error);
-  }
-}
-```

-## Credits
-
-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.
