Hi HN,I built Titan, a backend framework where you write routes and logic in JavaScript, and the CLI compiles everything into a single Rust + Axum binary using the Boa JS engine. No Node.js is required in production.The idea is to keep JS developer experience while getting Rust performance and a self-contained deployable server.Current features:JS route DSLAction system mapped to Rustesbuild bundlingGenerated Rust server with AxumHot-reload dev serverSingle-binary outputRepo: https://github.com/ezet-galaxy/-ezetgalaxy-titanWould love feedback on the architecture, DX, and whether this hybrid JS→Rust approach is useful.Thanks for reading!

Could you build this?
No Embedding a JavaScript engine (V8/Boa) inside Rust to compile JS routes directly into native Axum binaries requires deep systems programming, language runtime design, and compiler/bundler expertise.
What it would actually take: This requires building a custom bundler and embedding a JavaScript runtime (like rusty_v8 or Boa) into a Rust binary. You must implement custom Rust-to-JS FFI bindings that map Axum HTTP requests/responses into JS execution contexts, handle asynchronous I/O between the Tokio event loop and the JS runtime, and design an ahead-of-time (AOT) packaging system that bundles user code and runtime assets into a standalone binary.
Discussion
20 comments analyzed.
Competitors mentioned: Node.js with nginx load balancing, Bun (single-file executables, hot reload), V8 (JavaScript engine), C# .NET
Concerns raised: Boa JS engine is slower than V8 and Node.js, undermining 'Rust-level performance' claim, Comparison table claims are misleading/debatable (e.g., Rust-level performance, pure JS experience), Documentation is confusing, overstates capabilities, suggests AI-generated content, No clear benefit over Node.js with nginx for deployment simplicity, JS doesn't have Rust's compiler guarantees, so 'Rust performance' pitch is fundamentally flawed
Feature requests: Easy way to write hot-path code in Rust for optimization, Performance benchmarks against Node.js and other runtimes, Clearer, non-abstract documentation with concrete examples, Lightweight community feedback section in docs (no account friction)
