Why are both typescript-language-server and vtsls enabled?

After reading #25477 (comment) I was unclear about why that was the solution to the problem. It looks like a workaround.

The default value of language_servers is ["..."], which apparently includes both typescript-language-server and vtsls, and this results in duplicate panels, right? But what is the purpose of having typescript-language-server enabled if both LSPs are saying the same thing? Is it to offer users the option to pick one?

Seems to me like the default out of the box Zed settings will result in duplicate panels, so we should disable one or the other either way. Can someone shed more light on this?

Yea, I get the same thing. The docs make it seem like you should include ... in everything. https://zed.dev/docs/configuring-languages?utm_source=chatgpt.com#choosing-language-servers But it seems like it just spreads out everything so you end up with ["vue-language-server", "vtsls", "eslint", "vue-language-server", "vtsls", "eslint"] instead of it overwriting what's there.

You need to not include ... in your LSP settings

Interesting suggestion. But that seems like a lot of per-project work. How do I know which LSPs are even available for me to choose from?

They have a list of all of their supported languages which detail some of the LSP settings - https://zed.dev/docs/languages.

For something like Vue though, it's not clear what LSP's are available - https://zed.dev/docs/languages/vue... I kind of just figured it out by reading the github issues on that repo and googling "Zed vue", and using chatgpt o3 to search the internet for me, which led me to doing:

"Vue.js": {
      "language_servers": ["vue-language-server", "eslint"],
}

I had the "..." at the end and that was messing up the LSP. I also had no idea "eslint" was a thing until I asked o3 and it found a github thread with one of the devs mentioning it.

So morale of the story.... use ai to search the internet for you.

Thanks, that helps a lot! And I see that typescript-language-server is listed as an "alternate language server", so by definition both shouldn't be enabled.

Yeah that's correct. I think the Vue extension ships with it's own typescript LSP (iirc i read that on a random github issue) and then Zed has one already built in for typescript, tsx, and javascript.
