Last week, we landed a small change in #Metro to preserve comments: https://github.com/facebook/metro/releases/tag/v0.76.3

While this may seem insignificant, this means that Metro will no longer omit `__PURE__` annotations that bundlers rely on for tree shaking. As of Metro 0.76.3, you may get even smaller bundles if you're using `@rnx-kit/metro-serializer-esbuild`: https://github.com/microsoft/rnx-kit/tree/main/packages/metro-serializer-esbuild#readme

In simple examples, we've seen reductions of several hundred KBs. YMMV

#ReactNative #MetroBundler #TreeShaking

Very wild idea: a #JavaScript #bundler that actually supports ECMAScript modules, inlcuding #treeShaking and #HTTPS URLs.

And doesn't support butthole-shedding or bundling CSS, SVGs, and NFTs.
