All types are stale while origin is not explicitly saved

[pushkine]

A type coming from any other file will be stale until that other file is saved

My main concern is about the place where the extension gets the stale types from, I hope that those types being stale does not mean that the extension is running a whole duplicate typescript language server concurrent to the one vscode runs for standard .ts files

That would certainly explain why svelte types are only available within .svelte files... Is it a misconfiguration on my part ?

Your guess is right, it's a separate TS language server instance running. It's because it's not possible to my knowledge to add additional behavior on top of the existing TS server. There are TS plugins but those only run in the IDE, not when executing ts from the command line , so something like svelte-check would not be possible. That's also why the language server only runs on Svelte files, updates from outside are not known to it unless saved to disk.

If you know ways to improve it, I'm eager to hear your suggestions.

Maybe we can solve this in a way specific to the vscode extension by listening to other documentchange-events in the client and forward ts/js changes (denounced, 1 second) through a specific event to the language server. Diagnostics could be triggered afterwards, too.
