Offline First Architecture
Definition
Offline-First means building the application to assume there is no network connection by default. The app writes to a local database (like RxDB or PouchDB) instantly, and that local database syncs with the remote server completely asynchronously.
Explain Like I'm New
The app never waits for the internet. It saves everything locally immediately (so it feels infinitely fast), and then the app deals with uploading it to the cloud later.
