# fetch-intercept

[![Build Status](https://travis-ci.org/werk85/fetch-intercept.svg?branch=master)](https://travis-ci.org/werk85/fetch-intercept)

Interceptor library for the native fetch command inspired by [angular http interceptors](https://docs.angularjs.org/api/ng/service/$http).

`fetch-intercept` monkey patches the global `fetch` method and allows you the usage in Browser, Node and Webworker environments.

## Installation

```

npm install fetch-intercept --save

```

## Usage

_Note_: You need to require `fetch-intercept` before you use `fetch` the first time.

Make sure you have a `fetch` [compatible environment](http://caniuse.com/#search=fetch) or added a [appropriate polyfill](https://github.com/github/fetch).

```js

import fetchIntercept from 'fetch-intercept';

const unregister = fetchIntercept.register({

    request: function (url, config) {

        // Modify the url or config here

        return [url, config];

    },

    requestError: function (error) {

        // Called when an error occured during another 'request' interceptor call

        return Promise.reject(error);

    },

    response: function (response) {

        // Modify the reponse object

        return response;

    },

    responseError: function (error) {

        // Handle an fetch error

        return Promise.reject(error);

    }

});

// Call fetch to see your interceptors in action.

fetch('http://google.com');

// Unregister your interceptor

unregister();

```

## React-Native Compatibility

Support react-native `0.17` or higher versions.
