Express Admin

Express Admin is a tool for creating end user administrative interfaces for relational databases (MySQL, MariaDB, PostgreSQL, SQLite) in Node.js. Version 2.0.0, last released in 2023, with no set release cadence. It renders a fully responsive Bootstrap 3 UI with backend rendering via Hogan.js and uses jQuery for frontend plugins. Key differentiators: it is a single middleware that auto-generates admin UI from database schema, supports complex table relationships (one-to-many, many-to-many, etc.), and uses a settings.json file for configuration.
