Architecture

The modern app/public split, the full project tree, and how a request flows from browser to database and back.

Architecture

CB Genesis follows ColdBox's modern template layout: application code is fully separated from the public webroot, so nothing under app/ is ever directly web-accessible.

Request lifecycle

Every request enters through public/Application.bx, which bootstraps ColdBox before handing off to the router and, eventually, your handler:

sequenceDiagram
    Browser->>+public/Application.bx: HTTP Request
    public/Application.bx->>+ColdBox Bootstrap: loadColdbox()
    ColdBox Bootstrap->>+Main Handler: onRequestStart
    Main Handler->>+Router: Match route
    Router->>+Target Handler: Dispatch event
    Target Handler->>+Service Layer: Business logic
    Service Layer->>+ORM / qb: Data access
    Target Handler->>+View / Layout: Render response
    View / Layout-->>-Browser: HTML + Vite assets

Main.bx (app/handlers/Main.bx) is the implicit-event handler wired up in app/config/Coldbox.bx:

• onAppInit - runs settingService.preFlightCheck(), seeding any missing app settings into the database
• onRequestStart - loads prc.settings and prc.authUser for every request
• onException - the app-wide exception handler
