import JRPCWS from 'vue-json-rpc-websocket'

Vue.use(JRPCWS, 'wss://echo.websocket.org')

Enable Reconnection

In the Vue app entry file main.js

Vue.use(JRPCWS, 'wss://echo.websocket.org', {
  reconnectEnabled: true,
  reconnectInterval: 5000,
  recconectAttempts: 3
})

Enable Vuex integration:

import store from './store'
Vue.use(JRPCWS, 'wss://echo.websocket.org', { store: store })

Usage in Vue components

The plugin adds a $socket to your Vue instance.

In your components, you can handle websocket events by setting them up in the created or mounted hook.

• onOpen — event when socket is connected
• onMessage — event when socket receives a message from server (you don't need to use JSON.parse, data is already given in a form that is easy to use)
• onClose — event when socket is closed normally
• onError — event when socket is closed with error

// Component.vue
export default {
  name: 'Component',
  //
  created () {
    this.$socket.onOpen = () => {
      console.log('socket connected')
    }
    this.$socket.onMessage = (msg) => {
      console.log(msg)
    }
    this.$socket.onClose = (msg) => {
      console.log('socket closed')
    }
    this.$socket.onError = (msg) => {
      console.log('socket error')
    }
  }
}

Sending messages

sendData

this.$socket.sendData(method, params, action)

Example

this.$socket.sendData('example', { hello: 'world' }, 'setData')

Vuex module with example action:

export default {

  state: {
    data: []
  },

  mutations: {
    setData (state, data) {
      state.data.push(data)
    }
  }
}

In your component you will see the data:

<template>
  <div>
    <p>Test data: {{ wsData }}</p>
  </div>
</template>

<script>
export default {
  name: 'App',

  created () {
    this.$socket.onOpen = () => this.$socket.sendData('example', { hello: 'world' }, 'setData')
  },

  computed: {
    wsData () {
      return this.$store.state.wsData.data
    }
  }
}
</script>

Vuex Store integration

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex);

export default new Vuex.Store({
  state: {
    socket: {
      isConnected: false
    }
  },

  mutations: {
    socket_on_open ({ state, commit }, event) {
      state.socket.isConnected = true
      console.log('Socket connected')
    },

    socket_on_close ({ commit }, event) {
      state.socket.isConnected = false
      if (event.wasClean) {
        console.log('Socket closed clear')
      } else {
        console.error('Connection failure')
      }
      console.error('Code: ' + event.code)
    },

    socket_on_error ({ commit }, event) {
      console.error('Error')
    },

    socket_on_message ({ commit }, message) {
      console.log(message)
    },

    socket_reconnect ({ commit }, count) {
      console.log(count)
    },

    socket_reconnect_error ({ commit }) {
      console.error('Socket disconnected')
    }
  }
}
