WHAT WE LEARNED BUILDING A RUST RUNTIME FOR TYPESCRIPT

Summary from the TLDR Dev newsletter

Encore developed a 67,000-line Rust runtime for TypeScript to overcome Node.js's single-threaded limitations and establish a multi-language core for future extensibility. By offloading infrastructure concerns and integrating tightly with Node.js via N-API, this architecture achieves up to 9x higher throughput and 80% less latency compared to other frameworks.
