Expressa

Provides a Django-like admin UI for creating and managing collections, permissions, and data directly through the browser, as shown in the getting started example where navigating to /admin allows immediate setup.

Automatically generates complete REST endpoints from JSON schemas, eliminating the need to write boilerplate CRUD code for each collection, with endpoints like GET /:collection for querying.

Supports per-collection storage with MongoDB, PostgreSQL, or JSON files, allowing developers to choose the best database for each data type and even use JSON files for version control.

As Express middleware, it can be seamlessly added to existing Express applications with just a few lines of code, enabling mix-and-match with other middleware and custom endpoints.
