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: if you're using nvm or other node version manager, you need to configure tsserver.npm to your global npm executable path to avoid fetching types on vim start every time.

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.

Install

In your vim/neovim, run command:

:CocInstall coc-tsserver
