Query search against a channel #82

Open souvikinator opened 4 months ago

souvikinator commented 4 months ago

First of all thank you for such an amazing package.

This kind of a feature request: Searching videos / running a query against a specific channel.

Example:

const videos = await yts( { channelId: 'channel_id', query: "dummy query" } );

Expected output is it returns videos against the query from the provided channel only.

Would love to do further discussions on this. What can be the possible complexities.

Thank you

@souvikinator it's possible but there's a few difficulties in this case -- here are my thoughts:

1) it would require more than one request -- take for example https://www.youtube.com/@PewDiePie/videos -- the initial page load data we get includes a ytInitialData object but it only has about 30 videos in it -- and a new request for probably only 30 more -- this is clunky if a channel has 100+ videos

2) currently this library does not use a headless browser crawler (like puppeteer) because it's a lot of overhead and a lot more complicated (so it's not possible to get dynamically loaded data like through scrolling etc)

3) currently this library is designed to present data as a normal user would see it -- it sees YouTube the same way a normal user browsing YouTube sees it -- this is intentional and very simple -- it's not a very good deep crawler just like it would be difficult for a normal user to go through hundreds of videos by manually browsing YouTube

That being said -- it is possible -- but preferably in a way that would not require a headless browser like Puppeteer -- using puppeteer we could in theory just go to "https://www.youtube.com/@PewDiePie/videos" and scroll down using the puppeteer robot to get additional videos until we get them all loaded on the page -- this already feels like a clunky approach -- it should however be possible to tap into the client side YouTubes code and use the same api to make multiple requests -- however this would be a slow process as it would need to make many requests to get all videos

4) YouTube's search api that is available on normal YouTube actually has many filters -- maybe using those this would be achievable in a single request and then to create a method in this library that uses such a pre-filtered request

5) for your use case it looks like it would be best to use YouTube's official Data API -- I forget how much it costs but it isn't free

I'm happy to consider any PR's but it's almost better if you'd create a custom script to do what you want to do
