We pushed the first (experimental support) for Angular4 in sitecore-jss-angular package along with the basic sample app on GitHub: github.com/.../basic-sample-angular
The features include the Placeholder, Image and RichText components in Angular.
The workflow is the same as for the `basic-sample-react` app:
1. npm install or yarn
2. npm run dev or yarn dev
3. npm run setup
4. npm run config:deploy (this sample site is using a different host name, so make sure to configure the IIS binding accordingly see jss-basic-app-angular.config: `hostName="jssbasicappangular")
5. npm run package
Early feedback is welcome!
