# coc-tsserver

Tsserver language server extension for [coc.nvim](https://github.com/neoclide/coc.nvim).

Most of the code is from `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` and your TSX filetype to be `typescript.jsx` or
`typescript.tsx`. In coc.nvim, these filetypes are mapped to `javascriptreact`
and `typescriptreact` because that's what tsserver uses.

**Note** for javascript project, make sure you have [jsconfig.json](https://code.visualstudio.com/docs/languages/jsconfig)

## Install

In your vim/neovim, run command:

```
:CocInstall coc-tsserver
```

For yarn2 user what to use local typescript module:

- Add PnPify to your dependencies:

  ```
  yarn add @yarnpkg/pnpify
  ```

- Run the following command, which will generate a new directory called .vscode/pnpify

  ```
  yarn pnpify --sdk
  ```

### intructions for nvm users

Disable [nvm](https://github.com/creationix/nvm) with the following command:

```
nvm deactivate
```

Next, find out what the global path of your installed version of npm with the following command:

```
which npm
```

The output of the above command should go into the `tsserver.npm` property in your `coc-settings.json` file, a partial example listed below:

```
"tsserver.npm": "/usr/local/bin/npm"
```
