Bun [1] is a JS bundler based on esbuild’s source, but written in Zig. And it is about 3x faster than esbuild. I think its author Jarred is on HN as well.

Probably worth a submission on its own but I am just waiting till it is fully open source.

Edit: ( Deleted those Stats, since it may not be a fair comparison and it was probably not meant to be a fair benchmark in the first place. The details are still in the linked tweets. I do not know the author or am I in anyway affiliate with Bun. )

I am also wondering how much of those optimisation could be used on ESbuild. Since Rails 7 and Phoenix 1.6 will be using esbuild and not Webpack.

The numbers seem cherry picked though, I don't like this type of 197.96432100004x faster claims.

I’m pretty sure ESBuild’s creator has agreed that Bun’s performance claims are probably correct, and that there’s still more room for optimization of/beyond both.

Granted, those stats are for JSX, but it’ll be interesting to check out for sure.
