About

simple-helix-api is a package needed to simplify working with the Twitch API.

The library was created following the Twitch API documentation as much as possible. All requests are divided into categories for ease of use. Below is a list of current categories supported by package.

analytics, automod, channel, chat, clips, commercial, events, games, markers, moderation, other, polls, predictions, rewards, schedule, search, streams, subscriptions, tags, teams, users, videos

In addition, some requests that are associated with a list of something (a list of users, categories, clips, etc.) have one request in order to get a complete list.

Installation

npm:

npm install simple-helix-api

or using yarn:

yarn add simple-helix-api

Usage

Before we starting, be sure you have client_id registered in Dev Dashboard on Twitch.

Access Token

First, you need for Access Token provided by Twitch. With this package you can generate link to the endpoint that returns Access Token to you. If you already have, then skip this step.

const HelixAPI = require("simple-helix-api"); // you can use import

// Create client
const Helix = new HelixAPI({
    client_id: "xxxxxxx" // client_id from Twitch Dev Dashboard
});

// List of scopes you need for your application. Left it empty to request all scopes. See scopes list: https://dev.twitch.tv/docs/authentication#scopes
const scopes = ["chat:read", "channel:manage:predictions", "moderation:read"];

// Redirect uri must match to specified in Twitch Dev Dashboard
const redirect_uri = "http://localhost...";

// Generate auth link
const link = Helix.getAuthLink(scopes, redirect_uri);
console.log(link);

Now you can use this package on full power.

Example

Let's look at a basic example of working with package. In this example, we will get and output user information to the console.

Almost all requests requires an user ID. Get yours, store it and use everywhere.

Attetion! All requests and categories names matches with Twitch API documentation, but recommended to use autocomplete of your favorite code editor to see all categories and requests.

const HelixAPI = require("simple-helix-api");

const Helix = new HelixAPI({
    access_token: "xxxxxxx", // Your personal Access Token provided by Twitch. If you don't have one, see step above.
    client_id: "xxxxxxx" // Client ID from Twitch Dev Dashboard
});

(async () => {
    const user = await Helix.users.get("InfiniteHorror"); // Also you can specify user ID instead of user login
    console.log(user);
})();

More examples

There is a several examples of requests you can use with this package. Be aware that some requests requires additional parameters, so check the official documentation on the Twitch Dev Portal.

Update stream title and category

const game = await Helix.games.get("League of Legends");
const updated = await Helix.channel.modify(user_id, game.id, "en", "Title has been changed with simple-helix-api");

Start commercial

await Helix.commercial.start(user_id, 30);

Update chat settings

await Helix.chat.updateSettings(user_id, {
    follower_mode: true,
    follower_mode_duration: 10
});

Ban user

const user = await Helix.users.get("anyToxicPerson");
await Helix.moderation.ban(user_id, {
    user_id: user.id,
    reason: "Friendship is Magic"
});

Get all followers of channel

const followers = await Helix.users.allFollows(user_id);
console.log(followers);

Get all clips of channel

The time of response depends on count of clips of your channel.

const clips = await Helix.clips.all(user_id);
console.log(clips);
