Highly utilised, highly complex
What is Bun?
Perhaps the most notable advantage is Bun’s ability to maintain compatibility with existing Node.js codebases. This means developers can migrate to the new runtime without having to rewrite large portions of their code, reducing the barrier to entry for adopting the new runtime and lowering the associated risks with migration.
Will it live up to the hype?
Steve Sewell, Co-Founder and CEO of build.io has this to say on Twitter about his findings.
“Wow, ‘bun install’ is *ridiculously* fast[.] So fast I didn’t believe it worked. I had to stare at the console for a while to fully believe that the package install actually happened[.] Feels really nice to use, huge kudos to [Jarred Sumner].”
Bun is certainly fast; however, upon further inspection, there are currently over 1,100 open bug issues listed on the GitHub project. This raises concerns about its reliability. Nevertheless, with over 1,300 closed issues so far, it’s safe to say Oven is actively nurturing its development.
Node.js vs Bun.js
Bun’s development is venture backed with at least $7,000,000 dollars raised so far, the folks at Oven have plenty motivation to continue developing the runtime with Jarred Sumner leading it’s development since its inception, tallying up over 5,800 commits on the GitHub project with many more made every day.
However, this comes with one caveat which Node does not suffer from, if the main contributor to Bun’s development is removed from the process for whatever reason…What happens to Bun?
Node as we all know is an open-source project with an established open governance model which allows for its constant development without the need for one main contributor, Node will live on with its community.
Unlike Node, Bun natively supports TypeScript files. This support is made possible through its integrated transpiler, which allows you to run not only .js files but also TypeScript .ts, JSX and TSX files directly without the need for external dependencies or separate transpilation steps. This feature simplifies the development process by eliminating the need for additional tools or configurations to work with Typescript files in Bun.
