The document discusses building a web app that can be used offline by caching resources using a manifest file. It describes an app that queries a content API, produces HTML and manifest, allows an iOS app to point to the manifest to download files and load the local HTML and resources. The approach works best for simple apps and interactions, and could streamline iOS app development by deploying through a cached web app.

2. Content API NodeJS web app manifest HTML API Explorer User builds query User puts query URI into app App produces HTML and manifest

3. iOS App Change properties to point to manifest dist build

4. WebView Manifest Cache Download files from hosted manifest file to local disk Load local HTML, use relative directories to load CSS, Javascript and images URL Cache Intercept any other web calls and save to local disk
