Use this to create a brand new app extension.

Start on this site, where we have all the extensions: https://app-dev.2sxc.org/app-extensions/en-us/

Folder: D:\2sxc Apps Dev\Web\Portals\app-extensions\2sxc

Portal Work

1. Create a page for the extension
2. Create a brand new, empty app - naming convention for folder similar to previous, ca. app-extension-name
3. After creation, adjust name in app settings - like from app-extension-vcard to App Ext vCard

Add to Catalog

1. Add to catalog on the app-dev home (maybe copy an existing extension, adjust everything)
   1. Name
   2. App-Id
   3. etc.
2. Verify the link to open it works and opens the correct folder (this is only the case, if you set the correct AppId)

Repository

1. Use the link from above to open in VS-Code
2. Create git repo in the org https://github.com/2sxc-apps with the same name
3. init the repo, push according to GitHub instructions

Finish Setup

1. In the folder, create the extensions folder and then the necessary subfolder like vcard (all lower case)
2. go to the UI and create the extension-configuration

Start development

1. Create the extension in the App
2. Test it
3. add icon / description etc.
4. publish
