# Example Feast UI App This is an example React App that imports the Feast UI module. See the module import in `src/index.js`. The main change this implements on top of a vanilla create-react-app is adding: ```tsx import ReactDOM from "react-dom"; import FeastUI from "@feast-dev/feast-ui"; import "@feast-dev/feast-ui/dist/feast-ui.css"; ReactDOM.render( , document.getElementById("root") ); ``` It is used by the `feast ui` command to scaffold a local UI server. The feast python package bundles in resources produced from `npm run build --omit=dev.` The `feast ui` command will generate the necessary `projects-list.json` file and initialize it for the UI to read. **Note**: `yarn start` will not work on this because of the above dependency. ## Dev To test with a locally built Feast UI package, do: 1. `yarn link` in ui/ 2. `yarn install` in ui/ 3. `yarn link` in ui/node_modules/react 4. `yarn link` in ui/node_modules/react-dom 5. and then come here to do: ```bash yarn link "@feast-dev/feast" yarn link react yarn link react-dom yarn start ``` See also https://github.com/facebook/react/issues/14257.
