Twitch.js - Node (HTTP) auth provider

This is an AuthProvider implementation for d-fischer twitch package family that will automatically pop up a Twitch OAuth dialog in default user browser as soon as new scopes are requested.

Installation

To add this library to your project, just execute:

yarn add twitch-node-auth-provider

or using npm:

npm install twitch-node-auth-provider

Basic usage

To instantiate an ApiClient with this auth provider, just pass it to its constructor:

import { ApiClient } from "twitch";
import { NodeAuthProvider } from "twitch-node-auth-provider";

const authProvider = new NodeAuthProvider({
  clientId: "7m7uv94xk5lu42H2G27ay7nd1rpg",
  redirectUri: "http://localhost:4242/auth",
});

const client = new ApiClient({
  authProvider,
});

client.helix.users.getMe(true);

Options

name	type	optional	description
clientId	string	false	The client ID found in your Twitch Dev Console.
redirectUri	string	false	The redirect URI you provided in your Twitch Dev Console.
scopes	string \| string[]	true	A list of scopes that will always be requested.
accessToken	AccessToken	true	Represents the data of an OAuth access token returned by Twitch.

Force verify

To allow the user to "log out" and change to another account, use enableForceVerify():

(async () => {
  await client.helix.users.getMe(); // <- open login page
  await client.helix.users.getMe(); // <- already logged-in

  authProvider.enableForceVerify(); // <- force login for all the latter calls.

  await client.helix.users.getMe(); // <- open login page
  await client.helix.users.getMe(); // <- open login page

  authProvider.enableForceVerify(true); // <- force login on the next call only.

  await client.helix.users.getMe(); // <- open login page
  await client.helix.users.getMe(); // <- already logged-in
})();

Events

Listen all events:

authProvider.server.on("event", ({ eventName, data }) =>
  console.log(eventName, data)
);

Or listen one event:

authProvider.server.on("BROWSER_OPEN", () =>
  console.log("Opened Twitch login page in your default browser, take a look!")
);
