db-migrate supports multiple databases out of the box, including MySQL, PostgreSQL, SQLite, and MongoDB. This makes it a versatile choice for projects that may need to work with different database systems.

migrate is database-agnostic and can work with any database that supports raw SQL. However, it does not provide built-in support for multiple databases, so developers may need to implement their own database connection logic.

db-migrate supports both forward and backward migrations, allowing developers to easily roll back changes if needed. This feature is particularly useful for undoing mistakes or reverting to a previous state.

migrate also supports rollbacks, but it requires developers to define the rollback logic manually in each migration file. This can lead to inconsistencies if not done carefully.

db-migrate provides a powerful command-line interface with commands for creating, running, and rolling back migrations. The CLI is well-documented and easy to use, making it accessible for developers of all skill levels.

migrate has a simple CLI for running migrations, but it is less feature-rich compared to db-migrate. It may lack some advanced commands that could be useful for managing migrations in larger projects.

db-migrate is highly customizable and allows developers to create their own migration drivers, plugins, and command-line scripts. This flexibility makes it suitable for projects with unique requirements.

migrate is designed to be simple and lightweight, which limits its extensibility. However, its straightforward design makes it easy to understand and modify if needed.

db-migrate has comprehensive documentation and a large community of users, which makes it easy to find support and resources. The project is actively maintained, ensuring that it stays up-to-date with the latest best practices.

migrate has decent documentation, but it is not as extensive as db-migrate. The community is smaller, which may result in fewer resources and third-party plugins.

Creating a Migration with db-migrate

// Create a new migration
$ db-migrate create add-users-table

// Migration file example
exports.up = function(db) {
  return db.createTable('users', {
    id: { type: 'int', primaryKey: true, autoIncrement: true },
    name: { type: 'string' },
    email: { type: 'string' }
  });
};

exports.down = function(db) {
  return db.dropTable('users');
};

Running Migrations with db-migrate

// Run all pending migrations
$ db-migrate up

// Rollback the last migration
$ db-migrate down
