Toogles Client for JavaScript/NodeJS

This is a javascript client to be used with the Toogles Feature flag service. It can be used both on the client and on the server. It's a simple wrapper around node-fetch in NodeJS and the Fetch API in the browser.

Getting started

const Toogles = require('toogles-client');

const toogles = new Toogles('http://server.running.toogles');

toogles.includes('some-feature').then(function(someFeature) {
  if (someFeature) {
    // Render something to the users that has someFeature-flag set
  } else {
    // Render something else to the users that doesn't someFeature-flag set
  }
});

toogles.includes(['some-feature', 'some-other-feature']).then(function(features) {
  ....
});

Node js

$ npm install --save toogles-client

Browser

Download the latest release from this repository and include it in your application with <script>. To support older browser you must include polyfills for Promise and fetch.

API

`new Toogles(URL, config)`

URL - String

Url to a toogles endpoint

config - Object

{
   headers: {
        someHeader: 'to-send'
   }
}

`Toogles.includes(feature) -> Promise`

feature - String/Array

If a string is provided a Boolean is returned. If an array is provided an object with feature as key and flag(boolean) as the value:

Example:

Toogles.includes(feature1).then(function(feature1) {
  // feature1 = true/false
});

Toogles.includes(['feature1', 'feature2']).then(function(flags) {
  // flags = {
  //    feature1: true/false,
  //    feature2: true/false
  // }
});

If another type than String or Array is provided it will reject.
