Poem
Poem is a comprehensive toolkit for building type-safe web applications, APIs, and servers using the Rust programming language. It provides a foundation for developing web servers that handle HTTP requests with strong type safety.
The framework distinguishes itself by supporting multiple communication protocols through a protocol-agnostic handler mapping. This allows a single internal logic to be exposed across HTTP, gRPC services using protobuf definitions, and the Model Context Protocol for AI model integration. Additionally, it includes built-in tooling for generating OpenAPI v3 specifications and interactive documentation.
The project covers a wide range of capabilities, including request routing, trait-based middleware pipelines, and session management. It provides security features such as ACME-based automated TLS certificate renewal, CSRF protection, and CORS configuration. Other integrated capabilities include real-time data streaming via WebSockets and Server-Sent Events, static asset serving, and OpenTelemetry integration for distributed request tracing.
The framework is designed to support diverse deployment targets, including the ability to run web applications as event-driven serverless functions within cloud runtimes.
