api-twitch

ES6 JS classes for Twitch API requests and chat download

Installation

npm install api-twitch --save

Usage

Interact with Twitch's v5 REST API

Main features:

• High speed concurrent asynchronous download of Twitch chats from VODs
• Fetch VOD metadata, download URLs (m3u8) and top clips from a channel.
• Fetch Twitch channel information, list of VODs, and live status

Example setup - Get Stream Statuses

const { TwitchAPI } = require('api-twitch');

let twitchAPI = new TwitchAPI({twitchClientId: "<your twitchClientId>"});

let channelNames = ["stream_name1", "streamer2"];

// Get a hash of channel data to get key elements
let streamInfoHash = await twitchAPI.getDataForChannels(channelNames);

// Create array of promises and use await to block until ALL statuses are retrieved
let allStreamStatuses = await Promise.all(channelNames.map(name => twitchAPI.getStreamStatus(name));

// Order is maintained so we can just loop through channelNames
channelNames.forEach((name, index) => {
  console.log(`[D] TwitchAPI.streamStatus for ${name} is:`, allStreamStatuses[index]);
});

Get list of VODs clips from a channel with metadata, and the VOD chat messages

// After using getDataForChannels to get their channelIds, we can get their VODs
let recentVodList = await twitchAPI.getVods({channelId: streamInfoHash["streamer2"]._id});
let clipData = await this.twitchAPI.getClipData({channelName: "streamer2"});

console.log(`[D] TwitchAPI - recentVodList:`, recentVodList);
console.log(`[D] TwitchAPI - top clips:`, clipData);

let vodId = recentVodList[0]._id.replace(/v/gi, ''); // Get first Vod. get rid of v at start of vod ID
let vodMetadata = await twitchAPI.getVodMetadata(vodId);
let vod_download_urls = await twitchAPI.getVodURLs(vodId); // parse with m3u8-parser, trust me 

// Download chat
let vodChatData = await twitchAPI.getVodChatLogs({
  vodId: vodId,
  start: 0,
  length: vodMetadata.length, // .length is the duration of the full VOD in seconds
  numWorkers: 5, // max num concurrent requests in parallel
});

console.log(`[D] TwitchAPI - vodMetadata:`, vodMetadata);
console.log(`[D] TwitchAPI - vod_download_urls:`, vod_download_urls);
console.log(`[D] TwitchAPI - vodChatData:`, vodChatData); // NOTE: this can be BIIIIIG

// As for downloading and compiling the video data, that's a different module. Let me know if that interests you.

Notes

There are numerous checks for process.env.DEBUG to be defined.
If set to anything, it will invoke many useful debugging log statements.

NOTE: Any of these requests can 404 if a VOD or channel is deleted.
The API requests will return the number 404 in these cases.
