@types/sequelize

What is @types/sequelize?

@types/sequelize provides TypeScript type definitions for the Sequelize ORM, allowing developers to use Sequelize with TypeScript and benefit from type checking and autocompletion.

What are @types/sequelize's main functionalities?

Model Definition

Defines a model with specific attributes and their types. This allows for type-safe model definitions in TypeScript.

const User = sequelize.define('User', {
  username: {
    type: DataTypes.STRING,
    allowNull: false
  },
  birthday: {
    type: DataTypes.DATE
  }
});

Model Synchronization

Synchronizes all defined models to the database. This is useful for ensuring that the database schema matches the model definitions.

await sequelize.sync({ force: true });

Querying

Performs a query to retrieve all instances of the User model. TypeScript ensures that the returned data matches the User model definition.

const users = await User.findAll();

Associations

Defines associations between models, such as one-to-many or many-to-many relationships. TypeScript helps ensure that these associations are correctly defined and used.

User.hasMany(Post);
Post.belongsTo(User);
