npm install topper
- Write a simple functions to receive an TCP Payload, and a server socket context and register on a Topper Server instance.
const { Server } = require('topper');
const server = new Server('0.0.0.0', 4000);
const task = async (data, socket) => {
console.log(`New message!`);
await socket.write(`Message payload: ${data}`);
}
server.task(task);
nc localhost 4000
ห
verything is connected, Todd...
Message payload: verything is connected, Todd...
node app.js
New task registered on tcp://localhost:4000
New message!
- Write a function to receive an JSON string and execute some actions with payload
const { Server } = require('topper');
const server = new Server('0.0.0.0', 4000);
const task = async (data, socket) => {
socket.write(`hello, my name is ${data.name} and i'm ${data.age} old\n`);
}
server.task(task);
nc localhost 4000
{"name": "Matheus Fidelis", "age":22}
hello, my name is Matheus Fidelis and i'm 22 old
Create some arrays with task definitions and register on your server
const { Server } = require('./');
const server = new Server('0.0.0.0', 4000);
const tasks = [
{
name: 'Ping',
task: async (data, socket) => await socket.write('Pong\n')
},
{
name: 'Sum',
task: async (data, socket) => {
let sum = data.numbers.reduce((prev, curr) => prev + curr);
await socket.write(`The sum is: ${sum} \n`);
}
}
]
server.multiTask(tasks);
echo 'Sum {"numbers": [1, 2, 3, 4, 5]}' | nc localhost 4000
echo 'Ping' | nc localhost 4000
Output:
The sum is: 15
