Celebrate

Celebrate is a robust Express.js middleware designed for integrating Joi validation seamlessly into web applications. It allows developers to define validation schemas for various parts of an incoming request, including `req.params`, `req.headers`, `req.query`, `req.body`, `req.cookies`, and `req.signedCookies`. The library is currently stable at version 15.0.3 and undergoes regular maintenance with notable major version updates introducing breaking changes (e.g., v15, v14, v13, v8, v4, v3, v2). A key differentiator is its formal dependency on `joi`, ensuring a consistent and up-to-date Joi version is always used and also exported for consumer compatibility. It aims to simplify input validation in Express routes, providing a consistent error handling mechanism before any route handler is executed.
