twitch-api

Module for easily using all twitch.tv API v3 endpoints in nodejs

Installation

npm install twitch-api

Usage

Follow the Authorization Code Flow that you can find in the official twitch.tv API v3 documentation:

1. Send the user you'd like to authenticate to twitch.tv's authentication URL (you can get this URL using the convenience method getAuthorizationUrl once the module is initiallized)
2. If the user authorizes your application, she will be redirected to https://[your registered redirect URI]/?code=[CODE]. There you can get the code you need to get the user's access token.

Step 1: Initialization

var TwitchApi = require('twitch-api');
var twitch = new TwitchApi({
    clientId: 'your client id',
    clientSecret: 'your client secret',
    redirectUri: 'same redirectUri that you have configured on your app',
    scopes: [array of scopes you want access to]
  });

Step 2: Get the user's access token

twitch.getAccessToken(code, function(err, body){
    if (err){
      console.log(err);
    } else {
      /*
      * body = {
      *   access_token: 'your authenticated user access token',
      *   scopes: [array of granted scopes]
      * }
      */
    }
});

Once you have your user's access token, you can use it to query any authenticated resource the user has (and has granted you) access to.
