Node.js load balancer using Round Robin algorithm

Chokepoint

Chokepoint is a powerful Node.js package designed to streamline HTTP/HTTPS load balancing in your applications. It distributes incoming traffic across multiple nodes using Round Robin algorithm, ensuring optimal resource utilization and enhanced performance.

HTTP load balancing

import Chokepoint from "chokepoint";

const nodes = [
  { host: "localhost", port: 8001 },
  { host: "localhost", port: 8002 },
  { host: "localhost", port: 8003 },
];
const chokepoint = new Chokepoint(nodes);

chokepoint.listen(80, () => {
  console.log("Load balancer is running");
});

HTTPS load balancing

import Chokepoint from "chokepoint";

const nodes = [
  { host: "localhost", port: 8001 },
  { host: "localhost", port: 8002 },
  { host: "localhost", port: 8003 },
];
const chokepoint = new Chokepoint(nodes);

// Configure SSL certificate before listen
chokepoint.secure({
  key: fs.readFileSync("./ssl-key.pem"),
  cert: fs.readFileSync("./ssl-cert.pem"),
});

chokepoint.listen(443, () => {
  console.log("Secure load balancer is running");
});

Enable CORS

import Chokepoint from "chokepoint";

const nodes = [
  { host: "localhost", port: 8001 },
  { host: "localhost", port: 8002 },
  { host: "localhost", port: 8003 },
];
const chokepoint = new Chokepoint(nodes);

// Enable CORS for your request origins before listen
chokepoint.cors(["https://example.com"]);

chokepoint.listen(80, () => {
  console.log("Load balancer is running");
});
