+# coc-tsserver
+
+Tsserver language server extension for [coc.nvim](https://github.com/neoclide/coc.nvim).
+
+Most code from `typescript-language-features` extension which bundled with VSCode.
+
+## Install
+
+In your vim/neovim, run command:
+
+```
+:CocInstall coc-tsserver
+```
+
+## Features
+
+Almost same as VSCode.
+
+* Support javascript & typescript and jsx/tsx.
+* Install typings automatically.
+* Commands to work with tsserver.
+* Code completion support.
+* Go to definition.
+* Code validation.
+* Document highlight.
+* Document symbols of current buffer.
+* Folding and folding range of current buffer.
+* Format current buffer, range format and format on type.
+* Hover for documentation.
+* Implementations codeLens and references codeLens.
+* Organize imports command.
+* Quickfix using code actions.
+* Code refactor using code actions.
+* Find references.
+* Signature help.
+* Rename symbols support.
+* Rename imports on file rename.
+* Search for workspace symbols.
+
+## Configuration options
+
+* `tsserver.enable` set to `false` to disable tsserver language server.
+* `tsserver.trace.server` trace LSP traffic in output channel.
+
+And many more, which are same as VSCode, trigger completion in your
+`coc-settings.json` to get full list.
