Use monaco-editor-wrapper configuration to connect to the LSP service. Is there an automatic reconnection mechanism if the websocket is disconnected? Thanks

For example, in the following configuration, if the websocket is disconnected, is there a way to automatically reconnect and initialize it?

This is not built in, but one of the projects mentioned in the featured projects section in the README realizes it: https://github.com/Guyutongxue/clangd-in-browser/blob/main/src/editor.ts#L44-L102

vscode-languageclient doesn't know websocket connections. I guess we need to improve here (enhancement / bug). Do you remember this issue #478? 🙂

[kaisalmen]

@CGNonofr I have to investigate

[CGNonofr]

I don't think it needs to know about websocket, it's just about reconnecting

We use that built-in mechanism at CodinGame

Do you have some sort of tests for that?

[CGNonofr]

We do!

[kaisalmen]

We do!

Public or private repo? 🙂

I don't think it needs to know about websocket, it's just about reconnecting

I am suspecting that then there is a bug in vscode-ws-jsonrpc or how we handle / set it up in the client

[CGNonofr]

Maybe there is no tests specifically on the retry mechanism 🤔 don't remember well, everything is in https://github.com/CodinGame/monaco-languageclient-wrapper

[kaisalmen]

Thank you. Do we have/produce too many independent wrappers? 😅

[CGNonofr]

Probably, but for my defense, I think mine came first :D
