effect-http-api

What problem does it solve?

Designing HTTP APIs that stay consistent across server handlers, OpenAPI docs, and type-safe clients is error-prone when schemas are scattered or manually translated.

Core Features & Use Cases

• Schema-first endpoint definitions: define params, query, headers, payload, success, and error as Effect Schema so runtime validation and transport codecs are derived from one source.
• Typed server + client alignment: generate OpenAPI and derive type-safe clients from the same HttpApi definition, reducing drift.
• Middleware, security, and testing without spinning up a server: add security middleware and unit-test handlers using HttpApiTest utilities.

Quick Start

Use effect-http-api to define an HttpApiGroup with HttpApiEndpoint methods and schemas, then implement server handlers with HttpApiBuilder.group to get validated requests, documented routes, and client-ready types.
