A TypeScript library providing decorators and type-safe features for Sequelize v6, enabling class-based model definitions with @Table, @Column, and association decorators. It adds repository mode, scopes, hooks, and validation on top of Sequelize's ORM capabilities.

Use cases

• define sequelize models with typescript decorators
• type-safe orm for nodejs with typescript
• define one-to-many and many-to-many associations declaratively
• use repository pattern with sequelize
• add validation and hooks to database models
• migrate javascript sequelize models to typescript

When to choose

• you use Sequelize v6 and want type-safe, decorator-based model definitions
• you prefer class-based models over Sequelize's attribute-object style
• you want declarative associations like @HasMany and @BelongsToMany with type inference

When to avoid

• you use Sequelize v7 or a different ORM like TypeORM or Prisma
• your project is plain JavaScript without TypeScript
• you need the very latest Sequelize features not yet supported by this wrapper
