I used to use deoplete.nvim, LanguageClient-neovim with javascript-typescript-stdio, but they easily broken lots of time everyday and debug the problems is also quite challenging. So I made it to be able to load fork of vscode extension, and coc-tsserver implemented more than 95% features that vscode could provide. It's not easier to switch vim plugins, consider come back when you would like to try out some new features.
