Database Integration with NestJS and TypeORM

Modern backend development demands robust database integration that scales seamlessly with your application architecture. Connecting databases to your NestJS applications can feel overwhelming when managing schemas, relations, and migrations manually. This text-based course guides you step-by-step through integrating TypeORM with NestJS, from foundational setup to advanced query techniques. You will start with core database concepts and terminology before establishing your first connection and defining structured entities. Next, you will master data relationships, learn how to handle schema updates safely, and implement modern database practices. What you will learn: - Establish a secure connection between NestJS and relational databases using TypeORM - Define structured database entities with modern TypeScript decorators and type safety - Implement robust one-to-one, one-to-many, and many-to-many relationships - Perform efficient CRUD operations using repositories and query builders - Manage database schema changes safely using structured migrations - Apply modern backend practices including environment variables for configuration. The course begins with essential database definitions and configuration basics, then moves into active entity design, relational mapping, and reliable data migration workflows. This course is designed for backend developers and Node.js programmers who are new to NestJS or TypeORM and want to build a solid foundation in database management.
