Dev UI

Jazzy includes a powerful, built-in developer console accessible at /dev-ui. It provides real-time insights into your application’s state, environment, and data.

Features

1. Dashboard

Get a high-level overview of your application, including total routes, environment variables, and database status.

2. Route Inspector

View all registered routes, HTTP methods, and their associated middleware stacks. This is extremely useful for debugging complex routing logic.

3. Environment Viewer

Inspect your current .env configuration and environment variables securely (only available in development mode).

4. Database Explorer

A full-featured SQL client built into your browser:

Table Browser: List all tables and row counts.
Schema Viewer: View detailed column definitions, types, and constraints.
SQL Console: Execute raw SQL queries and see real-time results.
Insert Generator: Automatically generate INSERT templates for any table.

5. Cache Management

View all active keys in AppCache and clear them with a single click.

Security

Jazzy takes security seriously. The Dev UI is designed exclusively for development.

Auto-Disabled in Production: If APP_ENV is set to production in your .env, the /dev-ui route is completely disabled and will return 404.
Automatic Registration: You don’t need to import or configure anything. Calling Jazzy.serve() will automatically register the Dev UI if the app is in development mode.

APP_ENV=development # Enables Dev UI
