Encore built a 67,000-line Rust runtime to support TypeScript applications, replacing a Go-based approach that proved suboptimal. The architecture separates business logic (TypeScript) from infrastructure (Rust), enabling multi-threaded performance unavailable in single-threaded Node.js and establishing a polyglot pattern for future language support.
