rolldown 1.0.0-beta.54 on Node.js NPM

[1.0.0-beta.54] - 2025-12-11

⏱️ Plugin Timing Analysis

Added checks.pluginTimings option to emit warnings when plugins significantly impact build performance
More details: https://rolldown.rs/options/checks#plugintimings

Warning

For hooks using ctx.resolve() or ctx.load(), the reported time includes waiting for other plugins, which may overestimate that plugin's actual cost.

Additionally, since plugin hooks execute concurrently, the statistics represent accumulated time rather than wall-clock time. The measured duration also includes Rust-side processing overhead, Tokio async scheduling overhead, NAPI data conversion overhead, and JavaScript event loop overhead.
