Data Sync - Chris
A core component facilitating data synchronization with user devices. This component will leverage the useState hook to initialize state variables for syncStatus and syncError. These variables can track the current status of data synchronization and capture any errors, respectively. It utilizes the useEffect hook to initiate the data sync process automatically when the component mounts, ensuring the latest user data is retrieved from connected devices upon the user’s session start. A reference to Firebase Firestore service is acquired using the getFirestore function, allowing the component to interact with the platform’s cloud database.
The component defines a syncData function which is called to begin the data synchronization process. This function engages with the Google Fit API to fetch the latest activity data, then uses the Firestore service to update the user's records in the platform's database. Error handling is built-in, updating syncError with any exceptions thrown during the process, and setting syncStatus to reflect the current state of the operation. Within its render function, Data Sync displays synchronization status to the user, providing real-time feedback including successful sync confirmation or details of any encountered errors.
