Messager

A minimalistic social network, created using NodeJS + ReactJS.

Project Structure

The project consists of two parts:

• front folder contains the Next.js app
• back folder contains the Express.js server

---

How does it work (back)?

We use socket.io + express bundle. Socket_server.js is responsible for receiving messages and forwarding them.

const express = require ('express');
const app = express ();
const http = require ('http');
const server = http.createServer (app);
const {Server} = require ("socket.io");
const io = new Server (server);
const db_Worker = require ('./ DataBase_Worker');

const DataWorker = new db_Worker ("db.db")

const port = 3000
const hostname = "0.0.0.0"

app.use (express.static ('public'))

io.on ('connection', (socket) => {
    DataWorker.excute_request (`INSERT INTO messages VALUES (" User connected ");`)
    socket.on ('chat message', (msg) => {
        // io.emit ('chat message', msg);
        DataWorker.excute_request (`INSERT INTO messages VALUES (" $ {msg} ");`)
    });
    socket.on ('disconnect', () => {
        DataWorker.excute_request (`INSERT INTO messages VALUES (" User disconnected ");`)
    });
});

server.listen (port, hostname, () => console.log ("Server Up"))

As you can see, it doesn't brodcast messages now and saves them to the database.

To enable the broadcast function, uncomment the line //io.emit('chat message ', msg);
