TSW WebSocket API

This is not a standalone mod but a dependency for third-party applications

This mod adds a powerful websocket server (uWebSockets) to the game.

Developers of external applications can use this to obtain data from the game. The basic idea was developed for an external Ebula system, but I would like to create a central API for all external applications. The existing endpoints are gradually being expanded.

If you would like the websocket server to expose more data, please feel free to contact me. I will then try to provide the requested data.

Please intall the dependency (UE4SS) before installing this mod.

Important: This is a beta release of the mod. If you have any problems or suggestions for improvement, please use the comment function. You can also contact me via Discord.

How to use

After installing the game will expose a websocket server at localhost:9187.
The developer manual is available here: https://vanlueckn.github.io/tsw-websocket-docs

Known issues

Currently the port is hardoced to 9187

Roadmap

Add more useful data to expose via the server
Add configurable interval on subscription

Thanks, Luex! This will open up so many possibilities, I am sure it will be put to use very soon:-)

Thanks !
I know a third party app developer that will be interested by this !
This mod would actually help integrate their app core features in TSW (TSW is not fully integrated yet) so it could work as well as it works for TSC.
It definitely opens a new door for new mods :)

Threw together a web app which uses this mod to track the current train onto Openrailwaymap if anyone finds it useful

Nice. If you want any new features or if there are any problems, just let me know.

@Luex I did notice the mod itself is somewhat unstable; for example any time I disconnect the client while the game is running it crashes

Would it be possible to include scenario objectives, like next stop?

Luex 13 Feb 2025

Hi, i will have a look at this

Hi,
this project seems super cool. I am playing with the idea of connecting up real displays to TSW, so for example a destination board shows what youre driving in the game.
Would it be possible to get all infos related to services (headcode, service number, type, station stops, destination, times, etc) out of the API? I mean, taking it to the extreme, we could create a thing similar to ZUSI Display.

Cheers for the mod!

I've had a little less time in the last few weeks. In the future I will work more on updates again and convert this project completely to open source (so that everyone can participate)

Hey Luex and ClutchFred,

this is great! Although I hope you haven't already given up on it since you've been quiet for a while now. I'd really love to see all kinds of info from the trains becoming available via this API like LZB data or even just door status. Don't know if it's possible but it'd be great ^^

Cheers!
