vue-reactive-context v0.1.0-beta.4

vue-reactive-context

Reactive provide/inject for vue@2

Installation

npm install vue-reactive-provide
# or
yarn add vue-reactive-provide

Usage

import Vue from 'vue'
import VueReactiveContext from 'vue-reactive-context'

Vue.use(VueReactiveContext)

// or

Vue.use(VueReactiveContext, {
  provideName: 'provideReactive',
  injectName: 'injectReactive',
})

Generally you can simply replace provide and inject options in your component with provideReactive and injectReative. It will works just like what you are thinking of.

// in parent component file
export default {
  // ...
  provideReactive() {
    return {
      time: this.time
    }
  },
  data() {
    return {
      time: new Date()
    }
  },
  created() {
    setTimeout(() => {
      this.time = new Date()
    }, 1000)
  },
}

// in child component file
export default {
  injectReative: ['time'],
  template: '<span>{{ time.getSeconds() }}</span>'
}

How it works

This plugin is implemented in provide, watch, inject and computed in vue@2. Since the reative context works like computed properties, it won't make additional performance overhead significantly.
