coc-tsserver

Tsserver language server extension for 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

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 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"
