Automatically call HTMLBeaufity when exiting Insert mode in Vim

I'd like to automatically format html and js code when I exit insert mode. Currently I have ctrl f mapped to format the current file in my vimrc:

map <c-f> :call JSBeautify()<cr>

Is there a way I can trigger this command each time I exit insert mode? Thanks

Solution

Try to put this

augroup AuJsBeautify
   au!
   au  InsertLeave * call JsBeautify()
augroup END

in your .vimrc.

To know more about autocommands, read :h 40.3 and :h autocommand.

Or if you prefer mapping, you can just map it on your Esc

inoremap <Esc> <Esc>:call JsBeautify()<cr>
