This is a fork of eveningkid's denodb which appears to be abandoned and no longer functional due to dependency issues. I've updated the dependencies and am working on adding in some of the outstanding Pull Requests in the original repo.

DenoDB

  • 🗣Supports PostgreSQL, MySQL, MariaDB, SQLite and MongoDB
  • 🔥Simple, typed API
  • 🦕Deno-ready
  • Read the documentation
import { DataTypes, Database, Model, PostgresConnector } from 'https://deno.land/x/denodb/mod.ts';

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

const db = new Database(connection);

class Flight extends Model {
  static table = 'flights';
  static timestamps = true;

  static fields = {
    id: { primaryKey: true, autoIncrement: true },
    departure: DataTypes.STRING,
    destination: DataTypes.STRING,
    flightDuration: DataTypes.FLOAT,
  };

  static defaults = {
    flightDuration: 2.5,
  };
}

db.link([Flight]);

await db.sync({ drop: true });

await Flight.create({
  departure: 'Paris',
  destination: 'Tokyo',
});

// or

const flight = new Flight();
flight.departure = 'London';
flight.destination = 'San Francisco';
await flight.save();

await Flight.select('destination').all();
// [ { destination: "Tokyo" }, { destination: "San Francisco" } ]

await Flight.where('destination', 'Tokyo').delete();

const sfFlight = await Flight.select('destination').find(2);
// { destination: "San Francisco" }

await Flight.count();
// 1

await Flight.select('id', 'destination').orderBy('id').get();
// [ { id: "2", destination: "San Francisco" } ]

await sfFlight.delete();

await db.close();

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');
