Auto-Generating Migrations from Sequelize Models Using Sequelize CLI

One may possess pre-existing Sequelize models but desire to utilize migrations rather than database synchronization. Sequelize CLI offers a solution as outlined in an article that states, "When utilizing the CLI for model generation, you'll automatically obtain the necessary migration scripts."

To achieve this task:

Manual Generation of Migration Files

Avoid recreating models from scratch by manually generating migration files via the CLI command:

sequelize migration:generate --name [name_of_your_migration]

This action produces a vacant migration file skeleton. While it does not directly import your model structure, it provides a cleaner and more manageable approach compared to complete regeneration.

Note: Execute the command from the directory containing your migrations directory to prevent the CLI from creating a new migration directory.
