Documentation

Fetch Reject

A simple wrapper for fetch which rejects on HTTP error

Normal fetch does not throw on HTTP error (non-200 status code). This wrapper allows it to do so.

Install

$ npm install --save fetch-reject;

Usage

import fetch from 'fetch-reject';

// use just like normal fetch
fetch('http://httpstat.us/500')
  .then(date => doSomething(data));
  .catch(err => {
    console.log(err) // -> 'GET ... 500 (Internal Server Error)'
    console.log(err.status) // -> 500
  })

API

See the fetch docs for more.

fetch(url, [init])

Same as normal fetch, but it rejects with an Error object on non-200.

Returns

Type: Error

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;

createFetchReject(originFetch)

Returns a fetch function similar to the one documented above, but using the provided originFetch function. Can be used to enhance polyfills.

originFetch

Type: function

A function that complies with the original fetch spec. Will be used instead of window.fetch internally

Returns

Type: function

A function that acts similarly to fetch (detailed above), but uses the provided originFetch function instead.
