@disco/disco

Disco is a full-featured ORM that takes advantage of async/await, which makes the codebase and usage of the library vastly simpler. I spent weeks digging through existing node ORM implementations, only to find myself dissatisfied with how convoluted they were.

Installation

npm install @disco/disco

Usage

const mongo = require('@disco/mongodb')
const disco = require('@disco/disco')

const driver = mongo('mongodb://localhost/database')
const model = disco(driver)

const User = model.createModel('user', {
  firstName: String,
  lastName: String
})

const me = new User({
  firstName: 'Stephen',
  lastName: 'Belanger'
})

await me.save()

Custom Drivers

A driver is just a factory function which accepts a name and schema and produces a model class.

const disco = require('@disco/disco')
const assert = require('assert')

const model = disco((name, schema) => {
  return class Greeter {
    constructor (data) {
      Object.assign(this, schema.validate(schema.filter(data)))
    }

    greet () {
      return `Hello, ${this.name}`
    }
  }
})

const Greeter = model.createModel('greeter', {
  name: String
})

const me = new Greeter({ name: 'stephen' })
console.log(me.greet())

Notes

In typical node fashion, this module is meant to be simple. This means it lacks many features you may expect of a typical ORM which are intended to be implemented externally. The model itself is provided by the driver factory, which means it could be anything. The expected form is to wrap @disco/base-driver to produce a model class tailored to the specific data storage system needed. The base driver does not include relational components, that is provided by yet another external module.
