yt-channel-info

YouTube Channel Info NodeJS Documentation

This library is designed to receive channel data from YouTube without accessing the official API.
This method has several advantages:

• No API key is required, which you should put next to your code;
• No restrictions on key usage (1 million quota)

But there are also disadvantages:

• Data acquisition time increases by many times;
• Any change to the YouTube DOM entails non-working methods of this library.

You must consider this before you use YouTube Channel Info

Installation

npm i yt-channel-info --save

Usage

// If using require
const ytch = require('yt-channel-info')

// If using import
import ytch from 'yt-channel-info'

API

Community Posts Format

The objects in the array of community posts all follow a basic structure but vary drastically in the postContent field of the object.

-httpsAgent defined as for getChannelInfo()

postData = {
  postText: String,
  postId: String, 
  author: String,
  authorThumbnails: Array[Object], // Array of objects with links to images
  publishedText: String,
  voteCount: String,
  postContent: Object, // null if the post only consists of text
  commentCount: String
}

// If the post contains an image
imagePostContent = {
  type: 'image',
  content: Array[Object] // Array of objects with links to images
}

pollPostContent = {
   type: 'poll',
   content: {
      choices: Array[String],
      totalVotes: String 
   }
}

videoPostContent = {
   type: 'video',
   content: {
      videoId: String,
      title: String,
      description: String,
      publishedText: String,
      lengthText: String,
      viewCountText: String,
      ownerBadges: Object, // Object indicating possible badges {verified: false, officialArtist: false}
      author: String,
      thumbnails: Array[Object] // Array of objects with links to images
  }
}

playlistPostContent = {
   type: 'playlist',
   content: {
      playlistId: String,
      title: String,
      playlistVideoRenderer: Array[Object], // An array of minimized videoPostContent data
      videoCountText: String,
      ownerBadges: Array[Object],
      author: String,
      thumbnails: Array[Object] // Array of objects with links to images
   }
}

Proxy (HTTP Agent)

In order to use a proxy, you have to provide an assembled HTTP Agent. This can be achieved via additional packages like https-proxy-agent:

import HttpsProxyAgent from 'https-proxy-agent';
const proxy = 'http://127.0.0.1:10003';
const httpAgent = HttpsProxyAgent(proxy);

Tests

Tests and code standards are still in the process of being created. Check back later for information on how tests should be performed.

Contribution

PRs are welcome. Testing and coding guidlines are still in the works so I will try to get those created at a later point. Try to keep similar code syntax to the rest of the code.
