YouTube transcripts integration

Integrate with the YouTube transcripts document loader using LangChain JavaScript.

This covers how to load YouTube transcripts into LangChain documents.

Setup

You’ll need to install the youtubei.js to extract metadata:

npm

npm install @langchain/community @langchain/core youtubei.js

Usage

You need to specify a link to the video in the url. You can also specify language in ISO 639-1 and addVideoInfo flag.

import { YoutubeLoader } from "@langchain/community/document_loaders/web/youtube";

const loader = YoutubeLoader.createFromUrl("https://youtu.be/bZQun8Y4L2A", {
  language: "en",
  addVideoInfo: true,
});

const docs = await loader.load();

console.log(docs);
