[Vuejs]-Fetch Data with interval in javascript?

Ok, first of all it’s a Laravel Echo code. It may be using pusher behind the scenes, but saying it’s a pusher code is slightly incorrect.

Then, if I understand you right, you need some kind of debounce function. For example lodash offers one.

const debouncedFunction = _.debounce(() => {
    this.fetchData()
}, 5000);

Echo.private('channel').listen('.foobar', e => {
   debounced()
})

debounce will create debounced version of function which you can then call, or even cancel, because it comes with cancel method.

debouncedFunction.cancel()
