Let’s explore what they are and how to use them.

1. Improved Performance and Speed

– Node.js 20 incorporates the latest advancements in the V8 JavaScript engine, resulting in significant performance improvements. Let’s take a look at an example:

// File: server.js
const http = require('http');

const server = http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('Hello, world!');
});

server.listen(3000, () => {
console.log('Server running on port 3000');
});

By leveraging the performance optimizations in Node.js 20, applications like the one above experience reduced response times and enhanced scalability, resulting in an improved user experience.

2. Enhanced Security

Security is a top priority for any application, and Node.js 20 introduces several features to bolster its security. One noteworthy enhancement is the upgraded TLS implementation, ensuring secure communication between servers and clients. Here’s an example of using TLS in Node.js 20:

// File: server.js
const https = require('https');
const fs = require('fs');

const options = {
key: fs.readFileSync('private.key'),
cert: fs.readFileSync('certificate.crt')
};

const server = https.createServer(options, (req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('Secure Hello, world!');
});

server.listen(3000, () => {
console.log('Server running on port 3000');
});

With the upgraded TLS implementation, Node.js 20 ensures secure data transmission, safeguarding sensitive information.

3. Improved Debugging Capabilities

Node.js 20 introduces enhanced diagnostic and debugging capabilities, empowering developers to pinpoint and resolve issues more effectively. Consider the following example:

// File: server.js
const { performance, PerformanceObserver } = require('perf_hooks');

const obs = new PerformanceObserver((items) => {
console.log(items.getEntries()[0].duration);
performance.clearMarks();
});
obs.observe({ entryTypes: ['measure'] });

performance.mark('start');

// ... Code to be measured ...

performance.mark('end');
performance.measure('Duration', 'start', 'end');

In this example, the Performance API allows developers to measure the execution time of specific code sections, enabling efficient optimization and debugging.

4. ECMAScript Modules (ESM) Support

Node.js 20 embraces ECMAScript Modules (ESM), providing a standardized approach to organize and reuse JavaScript code. Let’s take a look at an example:

// File: module.js
export function greet(name) {
return `Hello, ${name}!`;
}

// File: app.js
import { greet } from './module.js';

console.log(greet('John'));

With ESM support, developers can now leverage the benefits of code encapsulation and organization in Node.js, facilitating better code reuse and maintenance.

5. Enhanced Worker Threads

Node.js 20 introduces improved worker threads, enabling true multi-threading capabilities within a Node.js application. Consider the following example:

// File: worker.js
const { Worker, isMainThread, parentPort, workerData } = require('worker_threads');

if (isMainThread) {
const worker = new Worker(__filename, { workerData: 'Hello, worker!' });
worker.on('message', message => console.log(message));
} else {
parentPort.postMessage(workerData);
}

In this example, the main thread creates a worker thread that receives data and sends a message back. With enhanced worker threads, Node.js 20 empowers developers to harness the full potential of multi-core processors, improving application performance.

6. Stable Test Runner

Node.js 20 includes an important change to the test_runner module. The module has been marked as stable after a recent update. Previously, the test_runner module was experimental, but this change marks it as a stable module ready for production use.

7. url.parse() Warns URLs With Ports That Are Not Numbers

url.parse() accepts URLs with ports that are not numbers. This behavior might result in hostname spoofing with unexpected input. These URLs will throw an error in future versions of Node.js, as the WHATWG URL API already does. Starting with Node.js 20, these URLS cause url.parse() to emit a warning.

Here is urlParse.js:

const url = require('node:url');
url.parse('https://example.com:80/some/path?pageNumber=5'); // no warning
url.parse('https://example.com:abc/some/path?pageNumber=5'); // show warning

Execute node urlParse.js . https://example.com:80/some/path?pageNumber=5 with a numerical port does not show a warning, but https://example.com:abc/some/path?pageNumber=5 with a string port shows a warning.

% node urlParse.js
(node:21534) [DEP0170] DeprecationWarning: The URL https://example.com:abc/some/path?pageNumber=5 is invalid. Future versions of Node.js will throw an error.
(Use `node --trace-deprecation ...` to show where the warning was created)
