RustAPI v0.1.397 Production-Ready Rust Backend Framework
RustAPI v0.1.397
Hey Product Hunt ๐
After months of building in public and iterating with the community, Iโm excited to launch RustAPI v0.1.397, the biggest feature release since v0.1.300 โ transforming RustAPI from a routing tool into a production-ready application platform.
๐ฅ Why This Matters
RustAPI started as an ergonomic Rust web framework with FastAPI-like ergonomics and strong OpenAPI support. Today itโs moving toward a full backend stack for high-performance, safe, and scalable services โ especially for APIs that power ML/AI and real-time applications.
๐ Whatโs New in v0.1.397
Hereโs what just landed:
๐ง Compile-Time Extractor Safety
No more silent runtime errors from body-consuming extractors โ ordering mistakes now fail at compile time with clear errors.
๐ Typed Error Responses + OpenAPI Sync
Declare API error responses directly on handlers and they show up automatically in Swagger UI.
๐ข Pagination & HATEOAS Helpers
Built-in offset & cursor pagination with RFC 8288 links + helpful headers.
โก Built-In Caching Layer
LRU cache + ETag + 304 Not Modified support out of the box โ no external proxies needed.
๐ Native Hot Reload / Watch Mode
Powered by a custom watcher โ no cargo-watch dependency โ fast refresh with debounce and smart filtering.
๐งฉ Event System & Lifecycle Hooks
In-process pub/sub + hooks like .on_start() and .on_shutdown().
๐ First gRPC Release
Dual HTTP + gRPC runtime powered by tonic & prost with a dedicated crate on crates.io
๐ What This Means for You
Whether youโre building:
๐ high-throughput JSON APIs
๐ง AI/LLM backends
โ๏ธ microservices with gRPC
๐ observability+monitoring tooling
๐ก scalable, cache-first systems
RustAPI now has the core building blocks to deliver production requirements without compromising safety, performance, or ergonomics.
