What are Knex migrations and how do I use them?
Knex migrations are a way to manage database schema changes in a structured manner. They allow you to create, modify, and delete tables and columns in your database. You can use them to ensure that your database schema is consistent across different environments.
How do I create a new migration in Knex?
To create a new migration, you can use the command knex migrate:make migration_name
. This will generate a new migration file in your migrations directory.
