Middleware between monaco-editor and LSP

[ghost]

Can middleware be added between editors monaco-editor and LSP to intercept communication between them? Release after processing, for example, I want to add some header files, but do not want to show this header file to the user, so add this header file when monaco-editor communicates with LSP. Delete the header file when LSP communicates with monaco-editor.

Hey @jlxzq,

this isn't really related to Langium - we neither build the monaco editor nor the language client packages here. But you should be able to register any middleware on the LanguageClient from the vscode-languageserver-client npm package. For any further questions you might want to ask the people over at the vscode-languageserver-node repo or at the monaco-languageclient.
