Socket.io with frappe and external applications

rtdany10 · July 18, 2024, 12:37pm

Has anyone successfully made socket.io connection with Frappe and an external (non-frappe)application?
It works fine for me in localhost, but from other domains/systems, it doesn’t work.

Firefox can’t establish a connection to the server at wss://clean-steaks-pull.loca.lt/socket.io/?EIO=4&transport=websocket.

This is unrelated, it’s about realtime (frappe’s implementation of socket.io for internal stuff) not working.

Was a silly mistake, making the server listen to 0.0.0.0 solved it.

If anyone needs the code:

custom_socket.js

const { Server } = require("socket.io");
const http = require("node:http");

const {
  get_conf,
  get_redis_subscriber,
} = require("../../../frappe/node_utils");
// the path here changes depends on where you place this file in your app

const conf = get_conf();
