coc-tsserver/Readme.md

## Local Change
Support disabling suggestionActions by code number.

### Example
In coc-settings.json:
```
{
  "typescript.suggestionActions.disabledCodes": [80001, 80002],
  "javascript.suggestionActions.disabledCodes": [80001, 80002, 7016]
}
```

# 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
unnecessary 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/sdks vim`, which will generate
  `.vim/coc-settings.json`, with content:

  ```json
  {
    "eslint.packageManager": "yarn",
    "eslint.nodePath": ".yarn/sdks",
    "workspace.workspaceFolderCheckCwd": false,
    "tsserver.tsdk": ".yarn/sdks/typescript/lib"
  }
  ```

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