Fetch-on-rest NPM

Fetch-on-REST

Fetch-on-REST is a RESTful API wrapper built around window.fetch.

GitHub provides a polyfill for fetch to work on all browsers. Fetch is also available on react-native by default.

This wrapper is intended to work on both the browsers as well as with react-native.

Usage

Using Fetch-on-REST is as simple as passing the data and handling the JSON response. Headers are automatically set to accept JSON and the responses are json objects.

var Rest = require('fetch-on-rest');
var api = new Rest('/api/v2');

api.get('users', {name: 'foo'}).then(function(response) {});
// GET request on '/api/v2/users?name=foo'

api.post('posts', {title: 'foo', content: 'bar'}).then(function(response) {});
// POST request on '/api/v2/posts' with data {"title": "foo", "content": "bar"}

API

Initialization

new Rest(basePath="/", addOptions=function() {}, useTrailingSlashes=false):

basePath: Is a string. Can be absolute or relative path.

addOptions(defaultOptions, url): Is an optional function. Can be used to modify the headers. Should modify the received defaultOptions object and not return a new object.

useTrailingSlashes: Default false. By setting true, .get('users') will hit the url /users/.

Example of addOptions:

// Adding same-origin and X-CSRFToken token
function addOptions(defaults, url) {
  defaults.credentials = 'same-origin';
  if(defaults.method != 'get')
    defaults.headers['X-CSRFToken'] = 'AUTHTOKENX';
}

var useTrailingSlashes = true;
var api = new Rest('/', addOptions, useTrailingSlashes);

Requests

.get(segments, query)

.post(segments, data, query)

.put(segments, data, query)

.patch(segments, data, query)

.del(segments, query)

.rawGet(segments, query)

All requests return a promise object. The promise object resolves to JSON response (except rawGet which resolves to text). URL parsing is handled using the exhaustive URI.js library.

segments: segments are the parts of url. Can be array or string.

query: query is the search or GET params part of the url. Should be a key-value object.

data: data is the json body to be sent in the request.
