Bun v0.2.0

• bun

  288 70,679 10.0 Zig

  Incredibly fast JavaScript runtime, bundler, test runner, and package manager – all in one

  

The version of that graph in the readme links to `bun/bench/react-hello-world` which makes use of `react-dom/server` so it is a slightly more involved test than sending plain `hello world`

On a local 4 core VM, generating the load locally:

Deno.serve() appears to be particularly bad for me at this test until you crank up the concurrent connections (>500) it gets up to 2k rps but it also falls over after that load.

The node react-hello-world.node.js test peaks at about 1.5k rps @ 32 connection

Bun running react-hello-world.jsx gets 8k rps with 32 connections. This uses a customised local copy of `react-dom/server` where [1] at least the `escapeHTML` function is switched for bun's native implementation, and this appears to be packaged (or will be?) with bun [2]. I'm not sure if anything else is different here as the bun packaged code is still minified. The `bench/snippets/react-dom-render.bun.js` [3] test comparing these only show the bun version of `react-dom/server` to be 1.5 - 2x faster on this VM so it appears there is something more to it. Maybe everything `react-dom/server` normally stresses is optimised in bun? or `escapeHTML` is very large on the flamegraph.

Running the react-hello-world.node.js server in bun results in about 1.9k rps @ 32 connection

Running react-hello-world.deno.jsx in bun doesn't work.

Futzing with react-hello-world.deno.jsx to load the cjs react builds will run in bun at about 1.9k rps

You will need the version of Zig used by Bun. It’s a few months old, just before LLVM 13 -> 14 migration

I believe cyclic imports are coming. And Nim does supports wasm...you can target it with `--cpu:wasm32`. You most likely want to pair that with emscripten as in https://github.com/treeform/nim_emscripten_tutorial
