Analysis of eventbus in Vue

This article mainly introduces the analysis of eventbus in Vue, which has certain reference value. Now I share it with everyone. Friends in need can refer to it

Without further ado, let’s get straight to the practical stuff

Existing pain points

• Do you just want to simply publish and subscribe to an event to notify the sibling component to execute a method?

• Are you still having a headache because you have to manually call uninstall (off) every time after introducing an eventbus?

• Are you still thinking about a series of methods of [pub, sub], [$on, $emit], [fire, listen] balabala for various buses? Having a headache due to the name?

If the above is your pain point, then today you start your happy days using Vue:

vue-event-proxy

Pass At the minimum cost, your Vue supports global events. With it, you only need to add the
global: prefix to complete global event publishing when you need to make global notifications. Is it simple?

    this.$emit('global:你的事件名字');

There is a release, but what about monitoring? How about

    this.$on('global:你的事件名字', () => {});

? Is there no change except adding global: in front of the event name? If you don’t understand this part of Vue, I have prepared it for you, the official document.

How to use

$ npm install --save vue-event-proxy

Add in the main entrance of your project (main.js generated by vue-cli):

  import EventProxy from 'vue-event-proxy';
  Vue.use(EventProxy);

Next, use it to your heart's content.
