node-signalr

A signalR client for node.js which support ASP.net but not ASP.net Core. For ASP.net Core signalR support use the offical client from Microsoft.

Installation

$ npm install @mfd/signalr

Usage

Create a instance of signalR client

const signalr = require('node-signalr')

let client = new signalr.client('http://localhost:8080/signalr', ['testHub'])

Configure client

// custom headers
client.headers['Token'] ='Tds2dsJk'

// set timeout for sending message 
client.callTimeout = 10000 // 10's, default 5000

// set delay time for reconecting
client.reconnectDelayTime = 2000 // 2's, default 5000

// set timeout for connect 
client.requestTimeout = 2000 // 2's, default 5000

Binding client events

client.on('connected', () => {
  console.log('SignalR client connected.')
})
client.on('reconnecting', (count) => {
  console.log(`SignalR client reconnecting(${count}).`)
})
client.on('disconnected', (code) => {
  console.log(`SignalR client disconnected(${code}).`)
})
client.on('error', (code, ex) => {
  console.log(`SignalR client connect error: ${code}.`)
})

Binding hub method

• Bind callback for receive message

client.connection.hub.on('testHub', 'getMessage', (message) => {
  console.log('receive:', message)
})

• Call the hub method and get return values asynchronously

client.connection.hub.call('testHub', 'send', message).then((result) => {
  console.log('success:', result)
}).catch((error) => {
  console.log('error:', error)
})

• Invoke the hub method without return values

client.connection.hub.invoke('testHub', 'send', message)

Start client

client.start()

End client

client.end()
