Gina is a tool to auto-generate and run migrations based on Sequelize ORM.

You can install this using:

npm install gina-sequelize

You'll need to install it globally so you can you the gina-cli

npm install -g gina-sequelize
# make sure to install ts-node too:
npm install -g ts-node

If this is the first time you are running Gina on your project you'll need to initialize it.

gina-cli init

This will generate a folder gina to your project. Inside this folder you will find the file initializeModels.ts. You will need to modify this file so that the initializeModels method inside it return a valid sequelize instance object that has all your models ALREADY loaded.

Once you have the initializeModels configured you can upgrade your database using:

gina-cli upgrade

Once you have the initializeModels configured you can generate auto migrations. It'll compare your loaded models with the database that you are connected. All differences should be listed on a new migration file that will be placed inside the folder gina/migrations.

gina-cli generate-migration "Creating user table"

If you want to edit the cli and test it you can install it locally:

npm install -g .
