Fix the auto complete issue: ~/Appdata/Local/nvim-data/plugged/coc.nvim


cd ~/Appdata/Local/nvim-data/plugged/coc.nvim
yarn install

Bash Aliases

nvim ~/.bash_profile

Source 2:

Close terminal or pane

Click on the panel and run :close
or quit vim: :qa

Practice with vim game


Fixing the issue

:!node app.js
/usr/bin/bash: /s: No such file or directory

Just add the line to your init.vim

set shellcmdflag=-c

Split window


Split terminal horizontally

:split term://$SHELL

Refresh tree after creating folder or a new file


or set it to refresh automatically, add this into your init.vim file

autocmd VimEnter * NERDTree


simply hit r to refresh the current directory's listing or R to refresh the root directory's listing .

Prettier configuration

Create a new file called coc-settings.json and paste the following files

  "eslint.autoFixOnSave": true,
  "eslint.filetypes": ["javascript", "javascriptreact", "typescript", "typescriptreact"],
  "coc.preferences.formatOnSaveFiletypes": [
  "tsserver.formatOnType": true,
