What are the best practices for managing entity relations in TypeORM?

When managing entity relations in TypeORM, it's important to define clear relationships using decorators like @OneToMany, @ManyToOne, etc. This helps maintain data integrity and simplifies queries.

Can you explain the difference between OneToMany and ManyToOne relationships?

Sure! A @OneToMany relationship means one entity can be related to multiple instances of another entity. Conversely, a @ManyToOne relationship means multiple instances of one entity can relate to a single instance of another.

How do I handle cascading operations in TypeORM?

You can handle cascading operations by using the 'cascade' option in your relationship decorators. This allows you to automatically propagate operations like save or remove to related entities.

What should I consider when designing my database schema?

Consider normalization to reduce redundancy, the types of relationships between entities, and how you plan to query the data. Proper indexing can also improve performance.
