Create an dockerized app with opds support

[batiti93]

Could you try to create the same app but not on the web , this is like porting your web app to a docker, so that when we want to download a cbz REMOTELY, your dockerized XTCJS automatically converts the file and then send it through opds to the XTEINK device. That would be a SUPER IDEA because when set up correctly, we can download on demand the CBZ on our choice directly using the x4/X3 with wifi or mobile hotsport without needing a cbz file, a computer, or a browser: just the nano reader !!! . And I don't think it is very hard as your already did the 90% of the job.
In the docker compose, we will need of course to bind an access to our CBZ library . PLEASE , buddy , do it for us !
anyway congrats for what u've done !

Hey! Thanks for pointing out this and creating the issue.

Will check what can I do!

It would be wonderful thing

@batiti93 I've never used OPDS so I tried to get everything you said. I'll be using it so I also need a review on this before merging it. Specially because codex tried to implement it without me knowing much about that. If you want to try it:

Before building the docker, make sure you are on the PR branch:

gh pr checkout 31

1. Start XTC.js with Docker:

docker compose up --build

2. Open the OPDS catalog URL from your device:

http://<your-computer-ip>:3000/opds

3. In CrossPoint/XTEINK OPDS settings, add that URL as a new OPDS server.

4. Browse the catalog. When you select a CBZ entry, XTC.js converts it on demand and serves the generated .xtc.

Useful URLs

http://localhost:3000/opds
http://localhost:3000/opds/books
http://localhost:3000/api/opds/status

To rescan after adding new CBZ files:

curl -X POST http://localhost:3000/api/opds/rescan

Settings

Edit docker-compose.yml if needed:

environment:
  XTC_DEVICE: X4
  XTC_SPLIT_MODE: overlap
  XTC_DITHERING: floyd
  XTC_CONTRAST: "4"
  XTC_2BIT: "false"

Defaults produce normal .xtc files for X4. Use XTC_DEVICE: X3 for X3.

I usually create projects , with a docker compose . Can you give the whole docker compose content ?

It's on the PR. Just clone the repo, switch to pr #31 with gh pr checkout 31 and just docker compose up.

Hello i've just tried to build with docker compose up but i have this error :

And when i've tried to compile just the backend i have this sqLite error :

@ghilesalt Thanks for trying this! My bad, had some local files that weren't merged so this failed. Commit 98b9530 should fix this. Please fetch the pull request and try the new version. You do not need to separately do bun run serve, just start the docker compose!

Hi @varo6 i've pulled your new commit and docker compose failed again :

Are you sure you don't have different files or changed the PR? If not, I also pushed a new commit that should make sure about that. But weird I haven't been able to reproduce it. Please switch to that PR and fetch latest commit if you didn't!

Also thanks for trying it and the debug :)

I achieved to make the thing run for now. Haven't tested on, xteink yet but the first think is that from an inkpad color i get error 500 (access denied to /library on terminal). The only way to get through is to chmod the folder. You need to edit some stuff when in the main branch docker compose file, to make things easy for everyone
xtcjs-1 | EACCES: permission denied, scandir '/library'

I will get back to you when i get the X4 in hands to see how the opds converter works

When I connect my 400GB manga library to XTCJS, my server crashes, whereas the Komga service, for example, uses no resources at all. I get the impression that XTCJS loads all the files, and that’s too much for a server. Perhaps I should load them in JSON format first?
