What are some advanced techniques for seeding data in TypeORM?
Advanced techniques for seeding data in TypeORM include using factories, custom seeders, and asynchronous seeding.
Can you explain how to create a custom seeder?
To create a custom seeder, define a class that implements the Seeder interface and implement the 'run' method.
What is the purpose of using factories in seeding?
Factories help generate fake data for your entities, making it easier to create realistic test data.
How do I handle relationships when seeding?
You can handle relationships by first seeding the parent entities and then referencing their IDs in the child entities.
Are there any libraries that can help with seeding?
Yes, libraries like Faker.js can help generate fake data, and TypeORM-seeding provides utilities for seeding.
