Using https requests instead of websockets

[GSri30]

Hello,

I'm exploring the monaco-languageclient package.

Requirement: To connect a monaco-editor (react app) with a language server provided by xtext via servlets (Completely use HTTP requests instead of websocket connection).

Progress: Currently exploring these files
(1) https://github.com/TypeFox/monaco-languageclient/blob/main/packages/examples/main/src/common.ts
(2) https://github.com/TypeFox/monaco-languageclient/tree/main/packages/examples/main/src/react

There is an implementation of connecting via websockets. I was wondering if it is possible to eliminate the websockets and tune the code to make it work via https requests.

Doubts:
(1) Is it even possible to achieve that?
(2) If so, what could be the possible flow to follow (I'm completely new to this dimension)

Hi @GSri30 you have to implement it yourself. But you can just write someting the implements the MessageReader and MessageWriter interfaces. We currently use two different ones in our examples:
jsonrpc over websocket:
https://github.com/TypeFox/monaco-languageclient/blob/main/packages/vscode-ws-jsonrpc/src/socket/reader.ts
https://github.com/TypeFox/monaco-languageclient/blob/main/packages/vscode-ws-jsonrpc/src/socket/writer.ts
used here:
https://github.com/TypeFox/monaco-languageclient/blob/main/packages/examples/main/src/common.ts#L44-L58

and web worker messages:
https://github.com/microsoft/vscode-languageserver-node/blob/main/jsonrpc/src/browser/main.ts (web worker)
used here:
https://github.com/TypeFox/monaco-languageclient/blob/main/packages/examples/main/src/langium/main.ts#L116-L118

So the way forward starts with implementing an AbstractMessageReader and AbstractMessageWriter yourself and plug those into createLanguageClient.

Yeah got it. Thanks.
