1. Neon JavaScript Native Extensions in Rust
2. JavaScript Native Extensions (C++) • Unsafe • Risky - segfaults! • Maintenance burden • Contribution barrier • Cross Platform Support
4. Meet Rust • Like C: compiled, statically typed, very fast • Unlike C: enjoyable to use, guarantees safety • "If it compiles, it doesn't crash" • Same guarantee as JavaScript with memory safety • Strong C/FFI support
5. Cargo - Dependency Manager
6. What is Neon? • Rust bindings for writing safe and fast native Node.js modules • Crash free memory protection (works with JS GC) • Parallelism (use multiple threads)
