TypeORM Integration Basics
Set up TypeORM with NestJS, define entities, and perform basic database operations using repositories.
Intro to TypeORM in NestJS
Welcome to integrating TypeORM with NestJS! TypeORM is an Object-Relational Mapper (ORM) that helps you work with databases using TypeScript or JavaScript.
Instead of writing raw SQL queries, you interact with your database using familiar object-oriented programming concepts like classes and objects.
Why Use an ORM?
ORMs like TypeORM offer several benefits:
- Abstraction: No need to write complex SQL.
- Type Safety: With TypeScript, your database interactions are type-checked.
- Portability: Easily switch between different database systems (PostgreSQL, MySQL, SQLite, etc.).
- Productivity: Faster development with less boilerplate code.
