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,
delay: 1000,
debug: false,
proxy: {
address: '',
port: ''
}
}
)

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

Angular, React, Svelte or any other framework

Currently we can't offer any other integration with other frameworks that works on top of NativeScript beyond VueJS, you are totaly open to create and send to us a PR. But, this is a pure NativeScript plugin, if you know how to manipulate your preferred platform you will be capable to include it in your project.

Vue Component

Declaring events using an Yoonit-Style

App.vue

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

<script>
export default {
data: () => ({
interval: null
}),
methods: {
doLoaded () {
// start the connection
this.$yoo.socket.open()
},
doPing () {
this.interval = setInterval(() => {
if (!this.$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.$yoo.socket.push('echo')
}, 2000)
}
},
yoo: {
socket: {
events: {
open ($socket) {
console.log("[YooSocket] Hey! I'm connected!")

clearInterval(this.interval)
return this.doPing()
},
message ($socket, message) {
if (!message) {
console.log("[YooSocket] Message is empty")
}

console.log(`[YooSocket] Received Message: '${message}'!`)
},
close () {
console.log("[YooSocket] Socket was closed")
},
error () {
console.log("[YooSocket] Socket had an error")
}
}
}
}
}
</script>

Or declaring events using your own already created methods

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>
