[discussion] maintaining typescript-language-server as part of the organization

[yyoncho]

As many of you know https://github.com/theia-ide/typescript-language-server is no longer maintained. While it is stable and "just works" there is a new development on in tsserver which is not exposed through the server (e. g. call hierarchy). We had a discussion in gitter with @danielmartin so I decided to move it here to see if there are other people interested in working on this.

I think that the overall complexity of typescript-language-server is not high because it is proxy so for someone familiar with js/ts won't be hard to keep up with tsserver features.

What's the status of https://github.com/sourcegraph/javascript-typescript-langserver? Has anyone tried this language server recently? It seems more actively developed as there's a company behind it, Sourcegraph.

If we decide that Theia is the best one, I agree about maintaining our own fork under the emacs-lsp organization. We'll need to advertise it well so that TypeScript developers that use Emacs, Vim, Sublime... can contribute to it. We can use JS/TypeScript Reddits and Twitter.

I have just tried this language server today. I think it is pretty decent, and mainly stable. Yet quick glance from the GitHub page; there are multiple issues not discussed.

That's sounds about right! This issue most likely going to be across any other editors that use this language server.

I encountered memory leaks when I tried the Sourcegraph server a few months ago. The Theia server generally works well for me.

It's not actively developed at all. Almost every commit from the last two years has been from dependabot.

I think the related discussion is here. neovim/nvim-lspconfig#250

The TypeScript team is slowly re-working tsserver to comply with LSP: microsoft/TypeScript#39459 (comment)

So I'm not sure if we need to worry about maintaining Theia's server anymore. In its present state, it still works well-ish for routine tasks, and anyone who needs better tsserver integration in the short term can always use tide until tsserver transitions fully to LSP.

@leungbk thank you. Closing the issue, if tsserver is going to support lsp there is no point to invest time in Theia server.
