Bun 1.0 - JavaScript meets speed of light

Yesterday, version 1.0 of Bun was officially unveiled, and now it's here, ready for use.

This marks a significant milestone in the JavaScript/TypeScript ecosystem.

Bun brings together a runtime environment, package manager, and bundler, streamlining the development process like never before.

Here is the official presentation:

Live Development Unveiled on Twitter/X

The development process has never been more transparent and engaging than with Bun, as it allows everyone to follow its progress live on Twitter/X.
Witnessing such a massive delivery of features and improvements in a short span of time is not only impressive but also inspiring.
This open and inclusive approach to development fosters a sense of community and collaboration among developers.

Mind-Blowing Speed

Bun has been on the radar of many developers for some time now, and one of the most striking aspects of this framework is its incredible speed.
However, it's essential to clarify that this speed is not solely about responding to HTTP server requests.
It encompasses the entire development workflow, making every step faster and more efficient.

Installing Packages
Bun streamlines the package installation process, reducing the time developers spend waiting for dependencies to download and install.
This seemingly small improvement can significantly boost productivity over time.

Running Unit Tests
Testing is a critical part of software development, and Bun doesn't compromise on this front.
Running unit tests is a breeze, allowing developers to identify and fix issues quickly.

Starting Your Program
Gone are the days of long startup times.
With Bun, launching your application is a swift process, enabling you to focus on coding rather than waiting.

IoT, Edge Devices, and Cloud Functions

One of Bun's standout features is its commitment to lower resource consumption.
This makes it particularly appealing for projects related to the Internet of Things (IoT), edge devices, and cloud functions.
In these domains, resource efficiency is paramount, and Bun's ability to deliver high performance with minimal resource usage positions it as a game-changer.

Furthermore, Bun's thoughtful integration of WebAssembly and Rust adds another layer of appeal, particularly in the realm of edge development.
This strategic combination not only enhances its versatility but also underscores its commitment to staying at the forefront of cutting-edge technology.

Future of Bun

In the ever-evolving landscape of development frameworks and tools, Bun stands out as a promising contender.
Its commitment to speed, efficiency, and resource optimization makes it a strong candidate for a wide range of projects.
As technology continues to advance, the need for tools like Bun that can keep pace with the demands of modern software development becomes increasingly evident.

In conclusion, Bun is not just a development framework; it's a testament to the relentless pursuit of efficiency and speed in the world of software development.
With its transparent development process, lightning-fast performance, and a focus on resource optimization, Bun has all the ingredients for a great future in the world of technology.

As developers continue to explore its capabilities, it's clear that Bun is here to stay and make its mark in the industry.

Speed is noticeable. Just Bun needs some stabilisation.

I totally agree.
I also wonder, if they can keep their current development speed.

I'd rather focus on quality, but that's personal opinion.

Interesting possibilities is the import rust file to the js project.

Wasn't Bun the thing that the CEO/owner/whatever said they wanted everyone involved to basically give up their lives to dedicate themselves to the project?

TechEmpower's last year benchmarks don't feature Bun. Do you have another set of benchmarks lying around? I am interested in staying informed with real numbers. You see, people always praise Node for its "high performance" and this is clearly a lie. Let's not fall into the same mistake with Bun.

There is this bun-http-framework-benchmark that is regularly updated and has comparison with a few libs like express, elysia (express like for Bun). Take a look at the benchmark but probably take it with a grain of salt.

This other article Node.js vs. Deno vs. Bun: JavaScript runtime comparison might be interesting as well

Thanks!
Most of the benchmarks are missing the comparison of RAM and CPU consumption, which is imo very important.
More important in real world, than raw throughput.

Well, there are a lot of benchmarks currently available. And if you look into a benchmark from last year, you probably won’t find Bun, as it is too young.

Also, as I said, I’m not so much into the request/sec thing, as in real world, you most of the time do stuff like database queries which “drop” that rate.
If you have 1mio req/s on a single instance, you might think about what’s maybe wrong on your infrastructure. Fault tolerance, DoS protection and so on?

What I can say: for example running unit tests is outperforming any other comparable node setup. Feels like the console output is the bottleneck here 😂.
Also, the startup/reload times are impressive compared to any other solution I tried for typescript.
You simply work faster.
And that’s mostly because Bun calls a way more often native functions compared to node.

One thing I miss in most articles about bun, that in fact the speed of bun only came from time savings on start and not from a faster execution. Many people will be misled by the statement that bun is fast, if you compare both with a long time running application, you will see that v8 can be faster than JavaScriptCore. So yes, bun is really fast on the edge, but Node.js points for long time running applications.
