Vapor 5 beta introduces async/await as the default, removes locks and storage requirements, and simplifies service dependency injection. The API remains largely familiar to Vapor 4 users, with the main changes being async calls for streaming bodies and direct dependency injection replacing extension-based service access.
Vapor 5 Beta was announced 10 years after Vapor 1.0, featuring a complete framework rewrite with async/await support, a new HTTP server built on Swift HTTP Server, streaming-first request/response bodies, and integration with Swift Configuration and HTTP Types. The beta requires Swift 6.4 and includes known issues with compression and WebSocket support.
