@mdx-js/language-server throws at initialisation with 'TypeScript module is missing'

[GNRSN]

I'm trying to set up mdx_analyzer as an LSP server in Neovim but the serves crashes on initialisation

Using:
@mdx-js/language-server: 0.2.2 (latest)
on node 18.18.0

The error thrown, 'TypeScript module is missing', stems from this assertion From neovim's side, communication with the language server happens through the cli with --stdio

See

I've done some sanity checkes like ensuring I have a clean npm install but to no avail.

I'm confused about installation section in the readme referring to remark-rehype so I'm unsure if I'm missing some component of setup? I couldn't find a Typescript dependency in the source so I my current theory is that I miss a typescript lib reference, similar to the path option for tsserver? but I'm unsure how to specify this or if volar expects this to be installed somehere in relation to cwd for execution?

Any advice for what I may be missing in terms of configuration or on how to further debug this will be much appreciated!

Hey @GNRSN, it’s great to see someone setup the MDX language server in another editor.

Admittedly, the docs need some work. The mention of remark-rehype is a copy-paste error. You don’t need remark-rehype at all.

The language server requires you to pass the path to the TypeScript library via initialization options. You can see how it’s done in the VSCode extension here. MDX analyzer is based on Volar, the same technology that powers editor integration for Astro and Vue. I suggest you have a look at https://github.com/neovim/nvim-lspconfig/blob/master/lua/lspconfig/server_configurations/astro.lua and https://github.com/neovim/nvim-lspconfig/blob/master/lua/lspconfig/server_configurations/volar.lua.

Thank you! Just copying the Astro config was enough to get me up and running. Hopefully this is helpful to anyone else trying to setup mdx for Neovim 😄
