Bun v1.3.14: The Update That Brings Speed and Power to the Table

As a developer who's been keeping an eye on the rising star that is Bun, I was excited to see the latest release, v1.3.14. This update brings a slew of fixes, new features, and experimental technologies that are sure to make a significant impact on the way we build and deploy our applications. In this article, I'll dive into the key highlights of this release and what they mean for developers like me.

The Power of Bun.Image

One of the most notable additions in this release is Bun.Image, a built-in image processing API. This is a game-changer for anyone working with images in their applications, as it eliminates the need for external libraries or services. With Bun.Image, you can easily resize, compress, and manipulate images directly within your code. Here's an example of how you can use it:

import { Image } from 'bun';



const image = await Image.fromFile('input.jpg');

const resizedImage = image.resize({ width: 800, height: 600 });

await resizedImage.toFile('output.jpg');

This code snippet demonstrates how to load an image from a file, resize it, and then save the resized image to a new file. The simplicity and ease of use of Bun.Image make it an attractive option for anyone looking to streamline their image processing workflows.

Faster Installs with the Isolated Linker's Global Store

Another significant improvement in this release is the isolated linker's global store, which enables 7x faster warm installs. For those who may not know, the isolated linker is a feature in Bun that allows for faster and more secure dependency management. By storing dependencies in a global store, Bun can avoid redundant work and speed up the installation process. This is especially beneficial for large projects or those with complex dependency graphs.

Experimental HTTP/2 and HTTP/3 Clients

The release also includes experimental support for HTTP/2 and HTTP/3 clients for fetch. This is an exciting development, as it allows developers to take advantage of the latest HTTP protocols and their associated performance benefits. While these features are still experimental, they demonstrate Bun's commitment to staying at the forefront of web technology. Here's an example of how you might use the HTTP/3 client:

import fetch from 'bun';



const response = await fetch('https://example.com', {

  protocol: 'h3',

});

const data = await response.json();

console.log(data);

Note that this is just a brief example, and you should consult the Bun documentation for more information on using these experimental features.

My Take: Is It Worth Upgrading?

As someone who's been following Bun's development, I'm impressed by the progress the team has made. The addition of Bun.Image, faster installs, and experimental HTTP/2 and HTTP/3 clients make this release a compelling upgrade for many developers. While some features are still experimental, they demonstrate Bun's commitment to innovation and performance. If you're already using Bun, I'd definitely recommend upgrading to v1.3.14 to take advantage of these new features and improvements. If you're new to Bun, this release is a great opportunity to explore what it has to offer. Overall, I'm excited to see where Bun will go from here and how it will continue to shape the web development landscape.
