⚙️ Usage

Server side

import { Server } from 'socket.io'
import { authorize } from '@thream/socketio-jwt'

const io = new Server(9000)
io.use(
  authorize({
    secret: 'your secret or public key'
  })
)

io.on('connection', async () => {
  const clients = await io.sockets.allSockets()
  for (const clientId of clients) {
    const client = io.sockets.sockets.get(clientId)
    client.emit('messages', { message: 'Success!' })
    // we can access the jwt payload of each connected client
    console.log(client.decodedToken)
  }
})

Client side

import { io } from 'socket.io-client'

// Require Bearer Tokens to be passed in as an Authorization Header
const socket = io('http://localhost:9000', {
  extraHeaders: { Authorization: `Bearer ${yourJWT}` }
})

// Handling token expiration
socket.on('connect_error', (error) => {
  if (error.data.type === 'UnauthorizedError') {
    console.log('User token has expired')
  }
})

// Listening to events
socket.on('messages', (data) => {
  console.log(data)
})
