Nuxt.js + Vuetify.jsでグローバルなイベントのやり取りを event bus でやってみる

Last updated at Posted at 2019-05-12

要は Snackbartoasts などのメッセージを $on$emit を使ってグローバルなイベントのやり取りをする感じ。
(これを global event bus というらしい)

npm install

plugins/event-bus.client.js 作成

import Vue from 'vue'

export default (ctx, inject) => {
  inject('bus', new Vue())
}

nuxt.config.js にプラグイン登録

plugins: [
    '~/plugins/event-bus.client.js'
]

Snackbars.vue コンポーネントを作成


<template>
  <v-snackbar
    v-model="isEnabled"
    :color="color"
    :multi-line="true"
    :timeout="timeout"
    top
  >
    {{ text }}
    <v-btn
      dark
      flat
      @click="isEnabled = false"
    >
      <v-icon>
        close
      </v-icon>
    </v-btn>
  </v-snackbar>
</template>

<script>
export default {
  data () {
    return {
      isEnabled: false,
      text: '',
      color: 'success',
      timeout: 5000
    }
  },
  created () {
    this.$bus.$on('snackbar:success', (text) => {
      this.isEnabled = !!text
      this.text = text
    })
    this.$bus.$on('snackbar:error', (text) => {
      this.isEnabled = !!text
      this.text = text
      this.color = 'error'
      this.timeout = 0
    })
  }
}
</script>

layouts/default.vue

<template>
  <v-app>
    <v-content>
      <nuxt />
    </v-content>

    <Snackbars />
  </v-app>
</template>

<script>
import Snackbars from '@/components/common/Snackbars'

export default {
  components: {
    Snackbars
  }
}
</script>

pages/index.vue

<template>
  <v-btn
    @click="successBtn"
  >
    successBtn
  </v-btn>
  <v-btn
    @click="errorBtn"
  >
    errorBtn
  </v-btn>
</template>

<script>
export default {
  methods: {
    successBtn () {
      this.$bus.$emit('snackbar:success', 'success!!!1')
    }
    errorBtn () {
      this.$bus.$emit('snackbar:error', 'error!!!1')
    }
  }
}
</script>

これで successBtnerrorBtn を押すと Snackbars でメッセージが表示されるはず。
