Next Js Daily: Turbopack Goes Wasm-Ready
A large coordinated push landed Turbopack support for wasm targets across a dozen crates, alongside fixes for correctness bugs in resolution, caching, and error reporting. A merge-order mistake briefly deleted several already-approved branches, forcing clean restores under new PR numbers.

Good morning. It's August 25th, and today's codebase activity centers on one big infrastructure effort: getting Turbopack building and running correctly on wasm.
Tobias Koppers landed roughly ten related fixes making Turbopack's Rust crates compile and behave on wasm targets. The pattern is consistent: features that assumed a native host — child process pools, SWC plugin hosts, Ctrl-C signal handlers, symlink creation, blocking event listeners — all silently or loudly failed…
Second theme: correctness fixes in module resolution and caching. Sokra's PR 97799 fixes server-relative imports — a path starting with slash now resolves from the project directory instead of the filesystem root, closing a real escape risk in monorepos. Marcos Hernanz's PR 97825 fixes Turbopack's handling of…
Third, smaller but real reliability fixes: PR 97698 stops a memory leak from piling up drain listeners on gzip streams under backpressure, and Ravi and Unstubbable's error-reporting fixes, PRs 97829 and 97830, clean up misleading stack traces and hidden AggregateError details in logs.
What's next: watch the turbo-persistence series — PRs 97873, 97888, and 97889 — which is mid-flight, adding an mmap…
