Build modern apps using NativeScript and WebSocket in Android and iOS

A NativeScript plugin to provide:

• Better and more stable Websocket connection
• Modern JS Code (ESNext)
• VueJS integrated plugin

Installation

npm i -s @yoonit/nativescript-websocket

Usage

All the functionalities that the @yoonit/nativescript-websocket provides is accessed through the YoonitWebSocket object. Below we have the basic usage code, for more details, your can see the Methods or the Demo Vue.

VueJS Plugin

main.js

import Vue from 'nativescript-vue'
import YoonitWebSocket from '@yoonit/nativescript-websocket/vue'

Vue.use(
  YoonitWebSocket,
  'wss://echo.websocket.org/',
  {
    protocol: '',
    timeout: 1000,
    headers: [],
    reconnect: true,
    debug: false,
    proxy: {
      address: '',
      port: ''
    }
  }
)

After that, you can access the socket object in your entire project using this.$yoo.socket

Vue Component

App.vue

<template>
  <Page @loaded="doLoaded"></Page>
</template>

<script>
export default {
  data: () => ({
    interval: null
  }),
  methods: {
    doLoaded () {
      // start the connection
      this.$yoo.socket.open()

      // declare all callback events
      this.$yoo.socket.events({
        open: this.doSocketOpen,
        message: this.doReceivedMessage,
        close: this.doSocketClose,
        error: this.doSocketError
      })
    },

    doPing () {
      this.interval = setInterval(() => {
        if (!this.$yoo.socket.getStatus()) {
          return console.log('[YooSocket] Socket closed')
        }

        console.log("[YooSocket] Sending 'echo' message!")

        // add your message/file to queue and call 'send' method
        return this.$yoo.socket.push('echo')
      }, 2000)
    },

    doSocketOpen ($socket) {
      console.log("[YooSocket] Hey! I'm connected!")

      clearInterval(this.interval)

      // onOpen event calls your function
      return this.doPing()
    },

    doSocketClose () {
      // onClose event
      return console.log('[YooSocket] Socket was closed')
    },

    doSocketError () {
      // onError event
      return console.log('[YooSocket] Socket had an error')
    },

    doReceivedMessage ($socket, message) {
      // onMessage event
      return console.log(`[YooSocket] Received Message: '${message}'!`)
    },
  }
}
</script>
