CryptoTribes MongoDB & API Developer

Design MongoDB schemas using Mongoose by creating separate models for each entity (User, Village, Building, Troop, Territory, Tribe, Battle) with proper validation rules, required fields, and data types. Apply indexing on frequently queried fields like territoryId or userId to ensure data integrity and query performance across your game's core objects.

Implement REST endpoints using Express to handle standard CRUD operations, then layer Socket.io on top to emit real-time events when data changes. This combination lets clients receive instant updates for gameplay events while maintaining traditional API endpoints for client initialization and admin tooling.

Add input validation middleware to sanitize and validate all incoming request data against your Mongoose schemas before database operations. Implement wallet-based authentication to verify user identity, then apply rate limiting and security headers to protect endpoints from abuse and unauthorized access.

Yes. MongoDB transactions let you group multiple write operations (like updating a territory owner, adjusting resources, and logging a battle) into an atomic unit. If any operation fails, all changes roll back, preserving data integrity when complex game logic spans multiple collections.

Write migration scripts that transform existing documents to match your new schema structure. Combined with Mongoose schema versioning and careful index management, migrations let you add fields, rename properties, or restructure nested data while keeping your production database online.

Create indexes on fields you query frequently (territoryId, userId, createdAt) and compound indexes on field combinations used together in filters. Monitor slow queries and adjust indexes to balance read speed against write overhead, especially for high-frequency operations like battle lookups or territory updates.
