First steps

Setting up your database with DenoDB is a four-step process:

  • Create a database, using Database (learn more about clients):

    const connection = new PostgresConnector({
  host: '...',
  username: 'user',
  password: 'password',
  database: 'airlines',
});

const db = new Database(connection);

  • Create models, extending Model. table and fields are both required static attributes:

    class User extends Model {
  static table = 'users';

  static timestamps = true;

  static fields = {
    id: {
      primaryKey: true,
      autoIncrement: true,
    },
    name: DataTypes.STRING,
    email: {
      type: DataTypes.STRING,
      unique: true,
      allowNull: false,
      length: 50,
    },
  };
}

  • Link your models, to add them to your database instance:

    db.link([User]);

  • Optional: Create tables in your database, by using sync(...):

    await db.sync();

  • Query your models!

    await User.create({ name: 'Amelia' });
await User.all();
await User.deleteById('1');
