import { DataSync } from '@datasync/sdk'
// Initialize the client
const sync = new DataSync({
apiKey: process.env.DATASYNC_API_KEY,

// Subscribe to real-time updates
const unsubscribe = sync
.collection('tasks')
.where('status', '==', 'active')
.subscribe((tasks) => {
console.log('Tasks updated:', tasks)
renderTasks(tasks)
})
// Create a new document (syncs automatically)
