React Native: How do you implement offline-first architecture?

1class OfflineFirstDB {
2  async save(data: Record) {
3    await this.localDB.put(data);
4    this.syncQueue.push({ type: "save", data });
5    this.processSync();
6  }

8  async processSync() {
9    if (!isOnline()) return;
10    for (const op of this.syncQueue) {
11      await this.remoteSync(op);
12    }
13    this.syncQueue = [];
14  }
15}
