Notice

The official server is not public

The server side of TYW Launcher is not distributed: the source is closed, and there is no binary, deployment package or setup guide. If you want your own distribution service, you have to build it yourself.

What this means

• Clients downloaded from the official site work as-is: they point at the server the project runs, and notices / updates / beta access come from there.
• If you want to publish your own notices, push your own updates or hand out your own beta keys, you need to write your own server. No ready-made program is provided.
• If you don't need online features, do nothing: with no server address configured the client simply runs offline. You lose notices and online updates; everything else is local.

The client only needs one address

To wire up your own server, the client resolves a single HTTP base URL in this order:

setting ServerUrl
  > TYW_SERVER environment variable
  > server.txt next to the binary / in the data directory
  > compile-time constant (written only into official builds, empty in open-source builds)

If none resolves, the client treats itself as offline: no error dialog, no report, just a hint in the bottom-left corner. What your server returns is entirely up to you.

If you build your own

There are only three kinds of work, and the shape is up to you (PHP, Go, Node, .NET — even a static file server covers part of it):

Capability	Rough shape
Notices	Return a piece of text per channel; the client shows it once
Version distribution	Return a version number and a download URL per platform / architecture / channel
Beta keys / bans (optional)	Validate a device code and beta key, or refuse specific devices

The official protocol is not published

The list above is only a functional breakdown. Field names, paths and authentication belong to the official implementation and are not documented; when self-hosting, design your own and patch the client accordingly (the client is open source).

Disclaimer

• Accounts, data and security issues caused by a third-party server are not the project's responsibility.
• The official client is distributed only through tml.tywmc.cn. Treat other sources with care.
