blong-validation

What problem does it solve?

Blong validation enforces consistent input and output contracts for Blong handlers, preventing runtime errors and ensuring API behavior matches documentation.

Core Features & Use Cases

• Automatic validation derived from TypeScript types or TypeBox schemas that also powers OpenAPI documentation.
• Runtime checks for parameters and responses, with automatic updates to API docs as types evolve.
• Use Case: When adding a new endpoint, define the contract once and rely on the framework to validate inputs, validate outputs, and generate OpenAPI specs.

Quick Start

Install the validation package, define a Handler type using TypeScript, and enable automatic validation in your server setup. Then run your app and observe runtime validation errors appear alongside updated OpenAPI docs.
