    Sequelize Six

    travis-ci Stories in Ready


    This package serves to assist in the creation of sequelize models via ES7 class syntax.


    • Babel.js with --stage 0 flag OR using the stage 0 plugin for babel 6.0+
    • Sequelize.js

    Extending from the Model Class

    Lets start with an example of what a model could look like with Sequelize classes.

    import {Model, hasMany} from 'sequelize-classes';
    import {STRING} from 'sequelize';
    @hasMany('Post', {as: 'posts', foreignKey: 'authorId'})
    export default class User extends Model {
        username = {type: STRING, allowNull: false, unique: true};
        email: {type: STRING, allowNull: false, unique: true};
        firstName: {type: STRING};
        lastName: {type: STRING};
        get name() {
            return `${this.firstName} ${this.lastName}`;

    Note that this class is just a class, not a sequelize model at this point. The purpose of the Model class is to set up your classes in such a way so that the Builder tool can create your sequelize model definitions properly.

    Using Builder to create your sequelize connection and define models

     import {Builder} from 'sequelize-classes';
     import {User} from './models/user';
     // Normal sequelize options.
     const options = {
       database: process.env.DB_NAME,
       username: process.env.DB_USER,
       pass: process.env.DB_PASS,
       config: {
         host: process.env.DB_HOST,
         port: process.env.DB_PORT,
         logging: false,
         dialect: 'postgres'
     // Pass sequelize connection options and an array of Classes extended from Model.
     const database = new Builder(options, [User]);
     // You can now access your sequelize instance via database.base and access all your models by name - database.User


    npm i sequelize-classes
