Class: Belt::WelcomeController

Inherits:

Defined in:
lib/belt/controllers/welcome_controller.rb

Overview

Gem-embedded welcome controller that serves the default "it works!" page.

Resolved via the ActionRouter's Belt

namespace fallback when no app-defined

WelcomeController exists. Gets replaced once the user defines their own root route.

Dual format:

- Browser / no Accept preference → HTML hero + stack check
- Accept: application/json (SPA / apiClient) → JSON payload for the React shell

The hero image (lib/belt/assets/belt-default.jpg) is the single source of truth — HTML embeds it, and JSON returns the same bytes as a data URI so the SPA matches.

Scaffold gives model + controller + routes + schema (not model-only).
