I wanted to extract a transcript from a youtube video but there was only a python script so I created this to do it in node. This package use unofficial YTB API so it can be broken over the time if no update appears.
$ npm i youtube-transcript
or
$ yarn add youtube-transcript
import { YoutubeTranscript } from 'youtube-transcript';
YoutubeTranscript.fetchTranscript('videoId or URL').then(console.log);
