Youtube Information Parser

This module allows you to retrieve information about title, creator, clicks, thumbnails and raw video urls of any youtube video you want!

Installation

To install this module, simply run the following command:

npm install --save youtube-url-parser

Usage

The first thing you have to do is to import it:

import * from "youtube-url-parser";

After that, you can create a new YoutubeLoader object like this:

let loader: YoutubeLoader = new YoutubeLoader("https://youtube.com/watch?v=VIDEO_ID");

Execute the getVideoLinks() function to retrieve all information about the video. This function returns a promise, which means you can either use the .then(...) and .catch(...) functions or prefix the function call with a await statement to handle asynchronous behavior.

When you only need the StreamingInfo which contains the video of the highest quality, execute the getBestQualityStreamingInfo(filters?: Filter): Promise<StreamingInfo> function. This will return the StreamingInfo with the highest video dimensions. To retrieve only videos which match specific attributes, like audio: true, specify them in the optional filters parameter. The parameter is of type [FilterType, keyof StreamingInfo, any][] which means, that you can provide an array of 3-tuples. The first element of the tuple represents the comparison type (e.g. ==, <=, >=, ...), the second the key you want to check (e.g. "audio") and the last element represents the value of the key (e.g. true). To retrieve the video with the highest quality which contains audio, you would call:

getBestQualityStreamingInfo([[FilterType.EQUAL, "audio", true]])

To filter for a set of StreamingInfo, that match your filter conditions, use the getFilteredStreamingInfo(filters: Filter): Promise<StreamingInfo[]> function.

Download videos

To download a youtube video, the easiest way to do so is to create a new instance of the YoutubeDownloader class. Provide the URL of the youtube video and the download location (relative Path with filename) as parameters in the constructor. After that execute the downloadBestQuality(): Promise<string> to download the video with the highest video quality. You can otherwise search for a StreamingInfo and download the video with the specific StreamingInfo.
