Add related videos to .getDetails func

[piccojs]

It would be great if I could get a list of videos related to a certain ID. Seems easy enough? please help.

Hi there,

Can you try the latest version? Just do:

npm install git+https://github.com/LuanRT/YouTube.js.git

I'm currently in the process of refactoring some things in the library and I recently added the getInfo method — it can retrieve pretty much everything you want and it is much faster than getDetails.

Ex:

const info = await session.getInfo('VCRkMsOFjI8');
console.log(info.watch_next_feed);

Note:
getDetails is still available but will be removed in future versions.

Merci monsieur 👍

It's not yet parsed, but I'll use it after the official release.

await yt.getInfo("x3IWvqMv8Ms").watch_next_feed returns undefined in v2.0.2.

The watch_next_feed is always undefined in 2.7.0, I presume YouTube changed their layout breaking the current way of extracting it.

It seems that the VideoInfo class is taking into consideration the layout of an authenticated session, but not that of an unauthenticated one. When logged in, the items of the watch next feed are inside an ItemSection, and along with that node will be a RelatedChipCloud. Something similar to this:

{
  secondary_results: [
    RelatedChipCloud {
      type: 'RelatedChipCloud',
      content: SuperParsedResult {}
    },
    ItemSection {
      type: 'ItemSection',
      header: null,
      contents: [Array],
      target_id: 'sid-wn-chips'
    }
}

An unauthenticated session's secondary_results array will be the watch next feed items themselves instead. No RelatedChipCloud and no ItemSection. So that's why it's undefined for you, it is always looking for an ItemSection even when it's not there:

YouTube.js/src/parser/youtube/VideoInfo.ts

Lines 162 to 164 in 22b9c17

	this.related_chip_cloud = secondary_results.firstOfType(RelatedChipCloud)?.content.item().as(ChipCloud);
	this.watch_next_feed = secondary_results.firstOfType(ItemSection)?.contents;

Honestly, I did not realize YouTube didn't allow logged out users to apply filters to that feed.

Anywho, I'll be fixing this later today. Thanks for the heads up!

Edit:
Some images to better demonstrate what I mean.
