How should I choose between @volar/language-service and @volar/kit?

[alamhubb]

Hello, I am developing an LSP language plug-in

@volar/kit is a package of @volar/language-service. Does it mean that @volar/kit should be used first?

But I see that the official examples do not use @volar/kit first, but @volar/language-service. Why is that?

If not, in what cases should @volar/kit be used and in what cases should @volar/language-service be used?

Or should @volar/language-service be used first, and only when @volar/language-service cannot meet the needs, then try to use @volar/kit?

@volar/language-service
This module provides language service functionalities, such as offering IntelliSense features. It depends on @volar/language-core for obtaining and processing virtual code, and then provides corresponding language services.

@volar/kit
@volar/kit is a module that encapsulates @volar/language-service. It provides a simplified interface for using Volar's diagnostic and formatting features within Node.js applications.

My current understanding is that kit should not be used when developing LSP. Kit is suitable for non-LSP scenarios. I don't know if my understanding is correct.

I’m not exactly sure what @volar/kit is. For https://github.com/mdx-js/mdx-analyzer I don’t use @volar/kit (yet), so you should be able to get started without it.
