The app checks if a database file exists already on Dropbox.On the iPad now, the user authorizes with Dropbox and is granted another token.App is installed by the same end user onto another device, such as an iPad.App uses this token to upload the database file to Dropbox.User inputs data into the app, and wishes to have a backup of their work.App is installed on an end user’s device.While the app would depend on an internet connection to support this feature, it was important to me that the app continue to work “offline first” in the absence of connectivity.Īt a high level, my concept for the overall experience looked like this: I envisioned a use case where my app could be installed on more than one device (say, a user’s iPhone and iPad), and up-to-date data would be available on each device. When I began looking into this topic, my goal was to provide a way to backup and sync my user’s data without storing it on a server that I would need to implement (and maintain). This post is accompanied by a fully-functional demo app that illustrates the approach: We’ll begin by walking through support for the Dropbox v2 authorization flow in a React Native app, and then use the token we are granted to enable synchronization of our database file via the Dropbox files HTTP endpoints. Next, let’s take a look at using the Dropbox HTTP API to backup our database and enable synchronization between devices. In the previous two posts we have bootstrapped a React Native project with TypeScript and CocoaPods, and then integrated an SQLite plugin to enable storing relational data on-device.
