GitHub user dosubot[bot] added a comment to the discussion: Does Superset 6.0.0 officially support the Extension Framework (.supx)?
<!-- Answer --> Good find! The presence of CLI and Extensions folders does indicate extension infrastructure exists. However, note that the [`superset/cli/`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/cli) and [`superset/extensions/`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/extensions) folders in the installation are **internal Superset components** (Flask extensions and CLI management tools), not the .supx extension loading system. To enable .supx extension loading, configure your `superset_config.py`: ```python FEATURE_FLAGS = { "ENABLE_EXTENSIONS": True, } # Directory where your .supx files are located EXTENSIONS_PATH = "/app/extensions" # Or your custom path ``` Then: 1. Place your `.supx` file in the `EXTENSIONS_PATH` directory 2. Restart Superset (for Docker: `docker compose down && docker compose up`) The [extension loading mechanism uses Webpack Module Federation](https://github.com/apache/superset/issues/34162) to dynamically load frontend assets at runtime. Extensions are served via the `/api/v1/extensions` endpoint. **Tip**: After restart, check your Superset logs for any extension-related messages - this will confirm whether the extension is being detected and loaded. Also verify your `.supx` file was [properly bundled using `superset-extensions bundle`](https://github.com/apache/superset/issues/34162) with valid `manifest.json` and `extension.json` metadata inside. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-assistant&utm_content=brand-link).* --- <sup>How did I do?
