I'm just doing some testing with JavaScript language feature with no DOM manipulation. So I'm editing a js file and I'm wondering how to simply run it and show the console output? I installed the moll/vim-node plugin, but no idea how to run js code.

    You can try something like :!node %. This will shell out to the external node program, passing the current filename as an argument. Output will be displayed on the screen, and you can press Enter to dismiss it. – tommcdo Apr 10 '15 at 10:39
  • The comment above by @tommcdo is a good concise solution that satisfied all I had been trying to achieve through more complicated means such as slime, et cetera. – jerome Jan 2 '18 at 2:32

Per this vim wikia entry you could create a shell execution to new buffer script and then extend it to run your code using node.

command! -complete=shellcmd -nargs=+ Shell call s:RunShellCommand(<q-args>)
function! s:RunShellCommand(cmdline)
  let isfirst = 1
  let words = []
  for word in split(a:cmdline)
    if isfirst
      let isfirst = 0  " don't change first word (shell command)
    else
      if word[0] =~ '\v[%#<]'
        let word = expand(word)
      endif
      let word = shellescape(word, 1)
    endif
    call add(words, word)
  endfor
  let expanded_cmdline = join(words)
  botright new
  setlocal buftype=nofile bufhidden=wipe nobuflisted noswapfile nowrap
  call setline(1, 'You entered:  ' . a:cmdline)
  call setline(2, 'Expanded to:  ' . expanded_cmdline)
  call append(line('$'), substitute(getline(2), '.', '=', 'g'))
  silent execute '$read !'. expanded_cmdline
  1
endfunction

command! -complete=file -nargs=* RunJS call s:RunShellCommand('node '.<q-args>)

Then if you run :RunJS % you should get a new buffer with the output of your node.js execution. Optionally you can call things directly using :Shell <cmd>

I think Codi is what you are looking for. It supports JavaScript and some other languages.

No plugin required! You can run node with the shell command :!

Run the entire file with :!/usr/local/bin/node %

Run the current line with :exec '!/usr/local/bin/node' '-e' shellescape(getline('.'))

I highly recommend https://github.com/Shougo/vimshell.vim for this purpose.

Its a vim plugin that allows you to run a terminal within vim. You can open the terminal in a new tab with

:VimShellTab

or quickfix window with

:VimShellPop

then you can run commands as usual, i.e.

node
