Bun 1.4
TL;DR
Bun 1.4 significantly enhances compatibility with Node.js by adding over 1,500 tests and fixing more than 2,900 issues, while improving performance metrics. Key improvements include a 5x reduction in idle CPU usage and a 50% faster startup on Linux.
✦ Why It Matters
Consider testing your applications with Bun 1.4 to leverage its performance improvements and Node.js compatibility.
Key Takeaways
- Run 'bun upgrade' to update to the latest version.
- Utilize new features like Bun.Image and Bun.WebView in your projects.
- Take advantage of parallel execution for tests with 'bun test --parallel'.
- Monitor performance improvements in your applications after upgrading.
How It Works
Bun 1.4's performance enhancements stem from a rewrite in Rust, which optimizes memory management and garbage collection. The new memory allocator, mimalloc, improves memory reclamation and reduces CPU usage by optimizing garbage collector timers and memory allocation strategies.
