You'll learn the essential structure and patterns for building full-stack Superset extensions. + +## Prerequisites + +Before starting, ensure you have: +- Node.js 18+ and npm installed +- Python 3.9+ installed +- A running Superset development environment +- Basic knowledge of React, TypeScript, and Flask + +## Step 1: Install the Extensions CLI + +First, install the Apache Superset Extensions CLI: + +```bash +pip install apache-superset-extensions-cli +``` + +## Step 2: Create a New Extension + +Use the CLI to scaffold a new extension project: + +```bash +superset-extensions init +``` + +The CLI will prompt you for information: + +``` +Extension ID (unique identifier, alphanumeric only): hello_world +Extension name (human-readable display name): Hello World +Initial version [0.1.0]: 0.1.0 +License [Apache-2.0]: Apache-2.0 +Include frontend? [Y/n]: Y +Include backend? [Y/n]: Y +``` + +This creates a complete project structure: + +``` +hello_world/ +├── extension.json # Extension metadata and configuration +├── backend/ # Backend Python code +│ ├── src/ +│ │ └── hello_world/ +│ │ ├── __init__.py +│ │ └── entrypoint.py # Backend registration +│ └── pyproject.toml +└── frontend/ # Frontend TypeScript/React code + ├── src/ + │ └── index.tsx # Frontend entry point + ├── package.json + ├── tsconfig.json + └── webpack.config.js +``` + +## Step 3: Configure Extension Metadata + +The generated `extension.json` contains basic metadata. Update it to register your panel in SQL Lab: + +```json +{ + "id": "hello_world", + "name": "Hello World", + "version": "0.1.0", + "license": "Apache-2.0", + "frontend": { + "contributions": { + "views": { + "sqllab.panels": [ + { + "id": "hello_world.main", + "name": "Hello World" + } + ] + } + }, + "moduleFederation": { + "exposes": ["./index"] + } + }, + "backend": { + "entryPoints": ["hello_world.entrypoint"], + "files": ["backend/src/hello_world/**/*.py"] + }, + "permissions": ["can_read"] +} +``` + +**Key fields:** +- `frontend.contributions.views.sqllab.panels`: Registers your panel in SQL Lab +- `backend.entryPoints`: Python module to load when extension starts + +## Step 4: Create Backend API + +The CLI generated a basic `backend/src/hello_world/entrypoint.py`. We'll create an API endpoint. + +**Create `backend/src/hello_world/api.py`** + +```python +from flask import Response +from flask_appbuilder.api import expose, protect, safe +from superset_core.api.types.rest_api import RestApi + + +class HelloWorldAPI(RestApi): Review Comment: Done. -- This is an automated message from the Apache Git Service.
