Thanks for the PR, and sorry for the delay it took me to review.

This subject is a tough one: By adding that check at the bottom of before_all, you still allow an external user to load images and videos. If you want to entirely restrict access, you'd need to put that code before return if (on line 64), which invloves re-thinking how auth is done (at the moment, we don't check if the user is authenticated on content proxy routes for performance reasons, at is saves us some DB calls).

Ideally, we should use a local cache to store user sessions (see the kemalcr/kemal-session shard), so that we don't have to call the DB all the time on every request.

Sorry for late reply, I have updated the code before "return if (line 64)", please review, thank you.

I built the patch from this specific pull request and its working: rix1337/docker-utube/general (arm image only)

Its broken however on the popular iOS client Yattee (even if logged in inside the app):
Could not load video

To help understand the error, I built Yattee locally and debugged the request that causes the it:

requestDescription String "GET https://HOSTNAME/api/v1/videos/e50028LAtAo"

This requests results in a http 500 error with the patch applied.
image

This is easily reproducible by requesting the URL when logged out:
image

When logged in, there is no 500 error.

I therefore assume, this patch is working correctly. To work with this new parameter, Yattee needs to request the videos Endpoint with the session cookie.

Also the health check from docker compose has now switched to unhealthy permanently:

    healthcheck:
      test: wget -nv --tries=1 --spider http://127.0.0.1:3000/api/v1/comments/jNQXAC9IVRw || exit 1
      interval: 30s
      timeout: 5s
      retries: 2

This endpoint should probably be replaced by another one, that response properly even when logged out.

Any suggestions?

One more thing I noticed. When using a third-party client like Yattee. Adding the instance and logging into an account is only possible when login_only: false. Are there some API endpoints that can be made accessible to allow adding an instance and logging into an existing account with login_only: true?

This is good, but I also found that Clipious client requires /api/v1/stat when adding a new server to the client. It loads this to check it is a valid server, and refuses if it doesn't work (currently it returns a 500 error, which should be a bug anyway). However, even if this additional endpoint is added the client doesn't load Popular and Trending (default pane) because it makes these requests unauthenticated (will need to raise this as an issue with Clipious)

Third party apps using the API are depending on some endpoints being unauthenticated such as /api/v1/popular and /api/v1/trending, currently there are giving a 500 error (but no traceback), and I haven't investigated the cause. These endpoints in https://github.com/iv-org/invidious/tree/master/src/invidious/routes/api/v1 are divided between Authenticated and others, where the others are implied to be Public. I tried adding authentication headers to the requests in Clipious, but the server side component doesn't seem to be expecting auth'.

Whilst adding "/api/v1/stats" facilitates login, the actual app' isn't really functional. So I think we state that api/v1 has a contract of having relatively open access, which makes me think that to implement this change, we either need to disable API access or create a v2. But someone closer to the project should really add their informed view of this!

Well, these two endpoints could be added to the whitelist as well. Since video playback still wouldn't be possible without logging in.

True, I assumed the intent of login was to reduce data leak... but popular and trending isn't really sensitive.

Just adding that after I raised my issue with Yattee they were able to quickly produce a fix, so your findings may be isolated to Clipious.

The patch from this pr works perfectly in combination with the patch from Yattee, when I enable login_only.

I added them to the suggestion, as @rix1337 pointed out, Yattee does show the Trending and Popular (if enabled) when login_only: true. So I guess Clipious might need to make some modifications to allow for this to work without having these endpoints exposed via the whitelist.

Server admins can set the instance to be private. Which means it is only accessible with a registered user account.

The endpoints `/api/v1/popular` and `/api/v1/trending` are whitelisted because some clients expect them to be open.

Invidious is great software, just discovered it. I'm a YouTube Premium user who can't stand all the extras and autoplay and visual noise any more (even Premium isn't enough).

Please guys make Invidious for logged in users only. We are running it on a small VPS and if even a small group of five people were to come and start watching 4K videos, our VPS would collapse.

At this point, having read the related issue and the [other commits](#4259, it seems more a question of ill-will than a technical obstacle. What I mean by ill-will is that some of the core developers don't believe that creating private Invidious instances should not be easy. Yes, I know about the http auth alternative but that effectively creates double login. I might be able to get by with whitelisted IP's but it's all a barrier to use, which a simple login barrier would be enough to solve.

That someone's stats program won't work when logged-in does not seem relevant. Mr Stats could just work on his own patch or not use the logged-in only feature.

Why don't you make logged-in only a paid feature? I'd happily pay $20 to support the project and to have this option. Yes, I could code it myself or hand apply these patches. But that doesn't help the project or others. It just means a whole lot of wasted duplicate effort.
