# coc-tsserver
Tsserver language server extension for
[coc.nvim](https://github.com/neoclide/coc.nvim).
Tsserver is part of [TypeScript](https://github.com/microsoft/TypeScript) which
provide rich features for javascript and typescript.
This extension is a fork of `typescript-language-features` extension which is
bundled with VSCode.
**Note:** for React to work as expected, you need your JSX filetype to be
`javascript.jsx` or `javascriptreact` and your TSX filetype to be
`typescript.jsx` or `typescript.tsx` or `typescriptreact`. In coc.nvim, these
filetypes are mapped to `javascriptreact` and `typescriptreact` because that's
what tsserver uses. For filetype like `typescript.javascript`, you need
configure `g:coc_filetype_map` variable in vimrc.
**Note** for javascript project, configure
[jsconfig.json](https://code.visualstudio.com/docs/languages/jsconfig) to make
tsserver understand your code.
**Note:** for rename import on file rename, you have to install
[watchman](https://facebook.github.io/watchman/) in your \$PATH.
**Note:** for [nvm](https://github.com/creationix/nvm) users, you need configure
`tsserver.npm` to your global npm path or configure
`"tsserver.disableAutomaticTypeAcquisition": false` to disable automatic typings
installation.
**Note:** tsserver could be quite slow to initialize on big project, exclude
unneunnecessary files in your jsconfig.json/tsconfig.json.
**Note:** if you're using WSL, copy you project files from mounted dirs to linux home otherwise tsserver will not work properly.

## Install
In your vim/neovim, run command:
`:CocInstall coc-tsserver`
For yarn2 ( >= v2.0.0-rc.36) user want to use local typescript module:
- Run command `yarn dlx @yarnpkg/pnpify --sdk vim`, which will generate
`.vim/coc-settings.json`, with content:
```json
{
"tsserver.tsdk": ".yarn/sdks/typescript/lib",
"eslint.packageManager": "yarn",
"eslint.nodePath": ".yarn/sdks"
}
```
## Features
Almost the same as VSCode.
- Supports javascript & typescript and jsx/tsx.
- Installs typings automatically.
- Commands to work with tsserver, including:
- `tsserver.reloadProjects`
- `tsserver.openTsServerLog`
- `tsserver.goToProjectConfig`

tsserver from `tsserver.tsdk` configuration or use bundled tsserver with this
extension.
