Instructions

•Import getAdminDb, COLLECTIONS from @/lib/firebase-admin
•Use Timestamp.now() for timestamps
•Convert to ISO string for API responses: createdAt.toDate().toISOString()
•Use batch writes for multiple operations (max 500)
•Use transactions for atomic operations

Quick Reference

typescript

import { getAdminDb, COLLECTIONS } from '@/lib/firebase-admin'
import { Timestamp, FieldValue } from 'firebase-admin/firestore'

// Get document
const doc = await db.collection(COLLECTIONS.PROJECTS).doc(id).get()

// Create with timestamps
const now = Timestamp.now()
await docRef.set({ ...data, createdAt: now, updatedAt: now })

// Update
await docRef.update({ field: value, updatedAt: Timestamp.now() })

// Increment counter
await docRef.update({ likes: FieldValue.increment(1) })
