Hyper – an API framework for Bun, distributed as source
Hyper is a new HTTP framework designed for Bun, allowing developers to easily manage components as plain TypeScript. It features a registry system that enables selective installation of parts without cluttering the repository. Hyper also simplifies route declaration by generating multiple outputs, including an OpenAPI document and a typed RPC client, from a single definition.
- ▪Hyper is distributed as source, allowing full access to its components.
- ▪The framework generates an OpenAPI 3.1 document and a typed RPC client from a single route declaration.
- ▪Plugins and sub-apps can be easily integrated using the .use() method.
