twitch-helix

Little helper class for the new Twitch API described in current Twitch API docs.
Transpiled and minified with Babel.

Feel free to contribute by creating issues and pull requests.

Installation

Yarn (recommended)

yarn add twitch-helix

npm

npm install --save twitch-helix

Library Usage

Example

Import the default class from this package and feed its constructor with a client ID and a client secret. You can generate those in your Twitch Developers Dashboard.
Try it out on RunKit!

import TwitchHelix from "twitch-helix"
// Or: const TwitchHelix = require("twitch-helix")

const twitchApi = new TwitchHelix({
    clientId: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    clientSecret: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
})

twitchApi.getTwitchUserByName("nightbot").then(twitchUser => {
    console.log(twitchUser.display_name) // Prints "Nightbot"
})

Construction

TwitchHelix is a class and you need to create an instance with:

const twitchApi = new TwitchHelix(options)

The options parameter is an object and can have following fields:

Field	Info	Default value
clientId	Client ID of your Twitch app	:no_entry_sign: (required)
clientSecret	Client secret of your Twitch app	:no_entry_sign: (required)
prematureExpirationTime	Time in ms for the access token to expire before it is meant to (Not implemented yet)	10000
autoAuthorize	Will call automatically call authorize() when needed	true
smartRetry	Will retry Twitch API requests up to 10 times if the server response is invalid	true

Implemented queries

Some of the common queries are wrapped into neat functions. Those are:

Promise	Name	Parameters	Return Value	Further info
Yes	getTwitchUserById	string id	Twitch user info object
Yes	getTwitchUserByName	string username	Twitch user info object
Yes	getTwitchUsersByName	Array usernames	Array of Twitch user info objects
Yes	getStreamInfoById	string id	Twitch stream object if user is currently streaming or null otherwise
Yes	getStreamInfoByUsername	string username	Twitch stream object if user is currently streaming or null otherwise
Yes	getFollowDate	string streamerId, string followerId	Date if follower follows streamer or null otherwise

Custom queries

You may need custom queries for retrieving data that is not wrapped into a function yet. Feel free to do so. Some API endpoints are still not implemented by Twitch in Helix API, so you can also use Kraken v5 API.

const helixQueryData = await twitchApi.sendHelixRequest("users?login=nightbot&login=moobot")
const krakenQueryData = await twitchApi.sendApiRequest("users?login=nightbot,moobot", {api: "kraken"})

Events

You can listen to some events.

twitchApi.on(eventName, eventHandler)

Event name	Parameters	Description
log-info	message	Emitted on INFO log messages
log-warn	message	Emitted on WARN log messages
log-error	message	Emitted on ERROR log messages

Command Line Usage

Here is an example:

node_modules/.bin/twitch-helix --client-id xxx --client-secret xxx "users?login=nightbot"

This will print:

Use the --kraken flag to query data from a Kraken endpoint instead of a Helix endpoint.
