The continued “Rustification” of the JavaScript ecosystem is the most significant trend highlighted here:
<ul>
<li>React Compiler is now integrated in Rspack 2.1 and available across Oxlint, SWC, and Next.js — with the compiler itself being rewritten in Rust.</li>
<li>Flow’s OCaml-to-Rust compiler port is now complete and shipping in Flow v0.319, with a 2x speedup.</li>
<li>Webpack 5.108 includes optimizations that leverage Rust-based tooling.</li>
<li>Node.js 26.4 and pnpm 11.8/11.9 continue to push performance.</li>
</ul>
The era of JavaScript tooling written in JavaScript is ending. The next generation is being built in Rust, and we’re seeing the results in real-time: faster builds, faster CI, faster feedback loops. This is the best time in years to be a frontend developer.
