It creates files which are working perfectly fine using sequelize db:migrate - even with foreign keys!

You are currently looking at the Tutorials and Guides for Sequelize. You might also be interested in the API Reference. To learn more about how to use Sequelize, read the tutorials available in the left menu. Begin with Getting Started. Sequelize is available via npm or yarn.

To connect to the database, you must create a Sequelize instance. This can be done by either passing the connection parameters separately to the Sequelize constructor or by passing a single connection URI:. The Sequelize constructor takes a whole slew of options that are documented in the API Reference for the Sequelize constructor.

If you're connecting to the database from a single process, you should create only one Sequelize instance. Sequelize will set up a connection pool on initialization.

This connection pool can be configured through the constructor's options parameter using options. If you're connecting to the database from multiple processes, you'll have to create one instance per process, but each instance should have a maximum connection pool size of such that the total maximum size is respected.

For example, if you want a max connection pool size of 90 and you have three processes, the Sequelize instance of each process should have a max connection pool size of Sequelize will keep the connection open by default, and use the same connection for all queries.

If you need to close the connection, call sequelize. A model is a class that extends Sequelize. Models can be defined in two equivalent ways.

The first, with Sequelize. The above code tells Sequelize to expect a table named users in the database with the fields firstName and lastName. The table name is automatically pluralized by default a library called inflection is used under the hood to do this. This behavior can be stopped for a specific model by using the freezeTableName: true option, or for all models by using the define option from the Sequelize constructor. Sequelize also defines by default the fields id primary keycreatedAt and updatedAt to every model.

This behavior can also be changed, of course check the API Reference to learn more about the available options. The Sequelize constructor takes a define option which will change the default options for all defined models. You can read more about creating models in the Model. If you want Sequelize to automatically create the table or modify it as needed according to your model definition, you can use the sync method, as follows:. Instead of calling sync for every model, you can call sequelize.
