Responsio

Responsio is a lightweight TypeScript library for standardizing REST API responses. Current stable version is 0.3.0, released as an early public alpha with ongoing development. It provides a simple wrapper to structure success and error responses consistently, reducing boilerplate in Express/Koa-based APIs. Unlike more opinionated formatters, it focuses on minimal configuration and direct JSON formatting, targeting developers who want a thin utility rather than a full framework add-on.
