Listning to incoming events

[Igal-Kleiner]

A client needs to send socket events to the server and the server has to listen to the incoming events. Socket.io implements the following methods: .on, .once, off, removeAllListeners. In Strapi v3 I was able to use them as follows:

const io = require('socket.io')(strapi.server, {
  // optional config
})

io.on('connection', function(socket) {
  socket.on('someCommand', () => {
    // ...do something here
  })
})

Alas, it is no longer possible with v4. And the StrapIO plugin currently doesn't support this much needed functionality.

I tried the solution you suggested in your Discord channel:

process.nextTick(() => {
  const _strapio = (require("strapio"))(strapi, {
    cors: { origin: "*", methods: ["GET", "POST"] },
  });

  _strapio.io.on('connection', () => {
    console.log('user connected')
  })

  strapi.io = _strapio.io
})

But getting this error: TypeError: Cannot read property 'on' of undefined. There's no io property on the object returned by the plugin.

i need this feature as well, since i have to put the socket inside the lifecycle file and emit an event from there
