I’ve been having issues making kak-lsp work with tsx files… by default `.ts` files work perfectly… but once you add `JSX`, all hell breaks loose.

After digging around, finally found [this github issue](https://github.com/typescript-language-server/typescript-language-server/issues/138#issuecomment-619873173)

adding

```auto
[language.tsx]
filetypes = ["typescript"]
roots = ["package.json", "tsconfig.json"]
command = "typescript-language-server"
args = ["--stdio"]

```

to your `kak-lsp.toml` makes it work with `.tsx` files!

I assume you removed the `[language.typescript]` entry, like at the bottom of [this comment on the kak-lsp issue](https://github.com/kak-lsp/kak-lsp/issues/211#issuecomment-532498773)

I don’t know much about typescript but I reckon that there is no downside to making `tsx` the default (at least with this specific language server)? So let’s make that the default to save future users the trouble?

yes I recently did! Found out there’s some issues when they’re both defined. I’ll edit the post.

– whoops, couldn’t edit it anymore 😬
