Get Started in Minutes

Three simple steps to build your first real-time application

1

Install the package

terminal
$ npm install emit.gg
2

Create your server

server.js
const { EmitApp } = require('emit.gg');
const app = new EmitApp();
 
app.on('/ping', (req) => {
    req.reply({ pong: true });
});
 
app.listen(3000);
3

Connect from client

client.js
const { EmitClient } = require('emit.gg');
 
const socket = await EmitClient.connect('ws://localhost:3000');
const result = await socket.request('/ping');
console.log(result); // { pong: true }
