PocketBase Best Practices

When to Apply

• Designing collections and schema structures
• Implementing API rules for access control
• Setting up authentication (password, OAuth2, MFA)
• Using the PocketBase JavaScript SDK
• Optimizing queries with filtering, sorting, and expansion
• Implementing realtime subscriptions
• Handling file uploads and storage
• Deploying PocketBase to production

Categories by Priority

Quick Reference

Collection Design (CRITICAL)

• coll-field-types: Use appropriate field types (json for objects, select for enums)
• coll-auth-vs-base: Extend auth collection for users, base for non-auth data
• coll-relations: Use relation fields, not manual ID strings
• coll-indexes: Create indexes on frequently filtered/sorted fields
• coll-view-collections: Use views for complex aggregations
• coll-geopoint: Store coordinates as json field with lat/lng

API Rules (CRITICAL)

• rules-basics: Always set API rules; empty = public access
• rules-filter-syntax: Use @request.auth, @collection, @now in rules
• rules-request-context: Access request data via @request.body, @request.query
• rules-cross-collection: Use @collection.name.field for cross-collection checks
• rules-locked-vs-open: Start locked, open selectively

Authentication (CRITICAL)

• auth-password: Use authWithPassword for email/password login
• auth-oauth2: Configure OAuth2 providers via Admin UI
• auth-token-management: Store tokens securely, refresh before expiry
• auth-mfa: Enable MFA for sensitive applications
• auth-impersonation: Use impersonation for admin actions on behalf of users

SDK Usage (HIGH)

• sdk-initialization: Initialize client once, reuse instance
• sdk-auth-store: Use AsyncAuthStore for React Native/SSR
• sdk-error-handling: Catch ClientResponseError, check status codes
• sdk-auto-cancellation: Disable auto-cancel for concurrent requests
• sdk-filter-binding: Use filter binding to prevent injection

Query Performance (HIGH)

• query-expand: Expand relations to avoid N+1 queries
• query-field-selection: Select only needed fields
• query-pagination: Use cursor pagination for large datasets
• query-batch-operations: Batch creates/updates when possible

Realtime (MEDIUM)

• realtime-subscribe: Subscribe to specific records or collections
• realtime-events: Handle create, update, delete events separately
• realtime-auth: Realtime respects API rules automatically
• realtime-reconnection: Implement reconnection logic

File Handling (MEDIUM)

• file-upload: Use FormData for uploads, set proper content types
• file-serving: Use pb.files.getURL() for file URLs
• file-validation: Validate file types and sizes server-side

Deployment (MEDIUM)

• deploy-backup: Schedule regular backups of pb_data
• deploy-configuration: Use environment variables for config
• deploy-reverse-proxy: Put behind nginx/caddy in production
• deploy-sqlite-considerations: Optimize SQLite for production workloads
