Trigger function on Vim Command

[CrashLaker]

Hi all.

Does anyone know how to trigger a function on a vim command? E.g. I want to trigger a Vue method when one types :w when using Vim mode.

Is it possible to translate it to Vue function as in:

methods: {
      onCmCursorActivity(codemirror) {
        //console.log('onCmCursorActivity', codemirror)
      },
      onCmReady(codemirror) {
        //console.log('onCmReady', codemirror)
      },
      onCmFocus(codemirror) {
        //console.log('onCmFocus', codemirror)
      },
      onCmBlur(codemirror) {
        //console.log('onCmBlur', codemirror)
      },
