New Trigger Page Component +**File**: `airflow-core/src/airflow/ui/src/pages/Dag/Trigger.tsx` +- **Purpose**: Full-page trigger form that supports URL parameters +- **Key Features**: + - URL parameter parsing using `useSearchParams` + - Form pre-population from URL parameters + - Integration with existing trigger functionality + - Responsive design with back navigation + +### 2. Router Configuration Update +**File**: `airflow-core/src/airflow/ui/src/router.tsx` +- **Changes**: + - Added import for `Trigger` component + - Added route `/dags/:dagId/trigger` to the DAG children routes +- **Purpose**: Enables direct URL access to trigger form + +### 3. DAG Page Updates +**File**: `airflow-core/src/airflow/ui/src/pages/Dag/Dag.tsx` +- **Changes**: + - Added `FiPlay` icon import + - Added trigger tab to the tabs array +- **Purpose**: Provides navigation to trigger form via tab + +### 4.

Implementation Summary +**File**: `IMPLEMENTATION_SUMMARY.md` (this file) +- **Purpose**: Summary of all changes made + +## Key Features Implemented + +### 1. URL Parameter Support +The trigger form now supports the following URL parameters: +- `conf`: JSON configuration string +- `dag_run_id`: Custom run ID +- `logical_date`: Logical date (ISO format) +- `note`: Note/description + +### 2. URL Structure +``` +/dags/{dagId}/trigger?conf={json}&dag_run_id={id}&logical_date={date}¬e={text} +``` + +### 3. Form Pre-population +- Automatically reads URL parameters on component mount +- Pre-populates form fields with URL parameter values +- Falls back to default values when parameters are missing + +### 4. Navigation +- Added "Trigger" tab to DAG details page +- Provides back button to return to DAG details +- Maintains existing trigger button functionality + +### 5. Error Handling +- Graceful handling of missing URL parameters +- Proper error states for DAG not found +- Loading states during data fetching + +## Technical Implementation Details + +### 1. Component Architecture +- Uses React Hook Form for form management +- Integrates with existing Airflow UI components +- Follows existing patterns for API calls and state management + +### 2.
