Hey @hediet, thank you for working on this. 🙏 .

We were using monaco-editor for a long time, but always struggle with the LSP support.

I'm so happy to see this implement in the monaco project. I hope you can finish it soon, and expose enought APIs for public usage.

My situation is about LSP-Server in Webworker (WASM-base), connect with the monaco like you did there.

@giautm LSP client support is already in! This is about making it easy to create LSP servers in a webworker.

Yes, I found the playground after comment there. And I was successful to integrate the LSP client with my LSP Server running in WASM. However, I need some "hack" to inject extra features to the client. I need access to the _connection which is not exported right now. Also the connection type is not exposed yet.

// LSP Client setup
class WasmFeature {
  constructor(c: any) {
    c.capabilities.addStaticClientCapabilities({
      experimental: {
        noFilesystem: true,
      },
    });
  }
  dispose() {}
}

class AtlasLspClient extends lsp.MonacoLspClient {
  createFeatures() {
    const store = super.createFeatures();
    //@ts-ignore
    store.add(new WasmFeature(this._connection));
    //@ts-ignore
    console.log("LSP Features initialized:", store, this._connection);
    return store;
  }
}
