Application Context (routes, views, config) #552
Description
Proposed new feature or change
Add a debug panel that shows the full request context in a structured, copyable format:
- Matched route, controller/action, parameters
- Rendered views and layout (in order)
- Applied filters/behaviors
With a "Copy as text" button for quick export:
Route: site/index
Controller: app\controllers\SiteController::actionIndex()
Layout: @app/views/layouts/main.php
Views:
- @app/views/site/index.php
- @app/views/site/_sidebar.php (partial)
Filters: AccessControl, VerbFilter
Laravel Telescope has a similar request watcher that shows route, middleware and controller info per request. Symfony Profiler also has a Router panel. Yii2 debug toolbar currently has no equivalent.
Useful for debugging unfamiliar projects and for providing context to AI coding assistants.
All data is already available via Yii::$app->requestedRoute, View events and controller metadata. Follows the existing panel architecture, no BC impact.
Would this be accepted as a PR?
Happy to implement this if there is interest.
