 1 | # Fetch Reject
 2 | >A simple wrapper for fetch which rejects on HTTP error
 3 | 
 4 | Normal `fetch` does not throw on HTTP error (non-200 status code). This wrapper allows it to do so.
 5 | ## Install
 6 | ```
 7 | $ npm install --save fetch-reject;
 8 | ```
 9 | ## Usage
10 | ```js
11 | import fetch from 'fetch-reject';
12 | 
13 | // use just like normal fetch
14 | fetch('http://httpstat.us/500')
15 |   .then(date => doSomething(data));
16 |   .catch(err => {
17 |     console.log(err) // -> 'GET ... 500 (Internal Server Error)'
18 |     console.log(err.status) // -> 500
19 |   })
20 | 
21 | ```
22 | ## API
23 | 
24 | See the [`fetch` docs](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) for more.
25 | 
26 | ### fetch(url, [init])
27 | 
28 | Same as normal `fetch`, but it rejects with an [`Error` object](#Returns) on non-200.
29 | 
30 | #### Returns
31 | 
32 | Type: `Error`
33 | 
34 | Will be `reject`-ed on non-200 response. An error object containing the `statusText` of the response. Has a `status` field which is equal to `response.status`;
35 | 
36 | ### createFetchReject(originFetch)
37 | 
38 | Returns a `fetch` function similar to the one documented above, but using the provided `originFetch` function. Can be used to enhance polyfills.
39 | 
40 | ### originFetch
41 | 
42 | Type: `function`
43 | 
44 | A function that complies with the original `fetch` spec. Will be used instead of `window.fetch` internally
45 | 
46 | #### Returns
47 | Type: `function`
48 | 
49 | A function that acts similarly to `fetch` (detailed above), but uses the provided `originFetch` function instead.
