Tired of Using Axios? Meet Undici, the Fast, Modern HTTP Client You Didn’t Know You Needed

Let’s be honest, when it comes to making HTTP requests in Node.js, most developers default to Axios. And while it’s solid, it’s not the only game in town. But what if I told you there’s a newer, faster, and more modern library that’s actually built by the Node.js team themselves? Say hello to Undici.

Why Should You Care About Undici?

Undici (which means “eleven” in Italian) isn’t just another HTTP client—it’s a major performance booster that’s flown under the radar for most developers. Unlike Axios, which sits on top of the old http module, Undici was designed from the ground up to be highly efficient and take advantage of all the latest improvements in Node.js.

Here’s why you should consider giving Undici a shot:

1. Performance That’s Hard to Beat: Undici was built with performance in mind, offering blazing-fast speeds, especially under heavy load. In fact, it’s used by Node.js itself, which should tell you something about how reliable it is.

2. Native HTTP/1.1 and HTTP/2 Support: Undici doesn’t just handle HTTP/1.1 well; it also has native support for HTTP/2, making it future-proof for your applications.

3. Lightweight and Minimalist: If you’re tired of bloated libraries and just need a simple, efficient solution, Undici is a great fit. It’s low on dependencies, reducing the bloat in your project.

4. Maintained by Node.js Core Contributors: The fact that it’s directly maintained by core Node.js contributors means it’s always up to date with the latest Node.js advancements, making it an incredibly reliable choice.

How to Use Undici in Your Node.js Project
Undici might sound complex, but getting started is easier than you think. Here’s a quick example of how to use it:

const { request } = require('undici');

// Sending a GET request
async function fetchData() {
  const { body } = await request('https://jsonplaceholder.typicode.com/posts/1');
  const data = await body.json();
  console.log('Fetched data:', data);
}

// Sending a POST request
async function createPost() {
  const { body } = await request('https://jsonplaceholder.typicode.com/posts', {
    method: 'POST',
    body: JSON.stringify({
      title: 'Undici in Node.js',
      body: 'This is a modern HTTP client you should definitely check out.',
      userId: 1
    }),
    headers: {
      'Content-Type': 'application/json'
    }
  });
  const data = await body.json();
  console.log('Post created:', data);
}

fetchData();
createPost();

Why Undici Might Be the Perfect Fit for Your Next Project

1. Optimized for High Performance: Whether you’re building a microservice or a monolithic app, speed matters. Undici’s optimized HTTP requests ensure you get the best performance with minimal overhead.

2. Direct Support from Node.js: You can rest easy knowing this library is maintained by the same people who build and maintain Node.js itself. It’s designed to work seamlessly with the latest Node.js versions.

3. Minimalism Without Sacrificing Power: If you prefer libraries that get out of the way and let you focus on the code, you’ll appreciate how lightweight Undici is while still offering the features you need.

4. Built for the Future: With built-in support for HTTP/2, Undici isn’t just about handling today’s needs—it’s ready for what’s next in web development.

Conclusion: Step Up Your HTTP Game with Undici

Undici might not have the name recognition of some other libraries (yet), but it’s already making waves among developers who prioritize performance and reliability. Whether you’re working on a high-traffic app or just want a modern tool that’s both powerful and minimalist, Undici is a solid choice.

So if you’re still reaching for Axios or sticking to the old http module, now’s the perfect time to explore Undici. It’s a library built with the future in mind—and it’s available today.
