I've successfully deployed my first SharePoint Framework extension to my SharePoint Online app catalog + site collection. My question is about deployment efficiency. Currently to deploy, I have to do a
gulp bundle gulp package-solution
...then upload the sppkg to the appcatalog along with the assets (js,scss) to a pre-configured CDN library. Then I have to install the actual app on the site collection.
What is the quickest way to deploy a new change if I modify the typescript file and the .scss file? Can I avoid fully retracting the app and re-adding it? That takes the longest because it makes you delete the previous version from the Recycle Bin.
