Rust-Based Glob Matcher Zeromatch Doubles JS Bundler Speed
Zeromatch, a Rust-based glob pattern matcher, outperforms the popular picomatch library by roughly 2x in one-shot matching scenarios by using a bytecode VM instead of regex. It excels when patterns are frequently recompiled but lags in cached matches due to FFI overhead. Developers should test pattern compatibility before migrating from picomatch.
Meridian48 take
Zeromatch is a smart optimization for specific bottlenecks, but its FFI trade-off means it's not a drop-in replacement for all use cases.
