sequelize-auto-migrations-ng

Migration generator for sequelize.

This package provides one tool:

• makemigration - tool for create new migrations

Install

npm install sequelize-auto-migrations-ng

Usage

• Init sequelize, with sequelize-cli, using sequelize init
• Create your models
• Create initial migration - run:

node ./node_modules/sequelize-auto-migrations/bin/makemigration --name <migration name>

• Change models and run it again, the migration file will be modified, it won't create a new one until you actually execute the migration.

  You can change this behavior using -k option and a different name for the migration.

• To preview new migration, without writing any changes, you can run:

node ./node_modules/sequelize-auto-migrations/bin/makemigration --preview

makemigration tool creates a table, SequelizeMetaMigrations in your database, that is used to calculate difference to the next migration. Do not remove it!

Executing migrations

• Use standard sequelize-cli sequelize db:migrate
• To start from a revision, use --from <name>

Reverting migrations

• Use standard sequelize-cli sequelize db:migrate:undo

For more information, use makemigration --help, sequelize --help db:migrate

TODO:

• Migration action sorting procedure need some fixes. When many foreign keys in tables, there is a bug with action order. For now, please check it manually (--preview option)
• Need to check (and maybe fix) field types: BLOB, RANGE, GEOMETRY, GEOGRAPHY
• This module has been tested with postgresql (I use it with my projects). Test with mysql and sqlite.
