Parsing URI

const Connection = require('mongodb-connection-model');

Connection.from(
  'mongodb://someUsername:testPassword@localhost',
  (error, result) => {
    console.log(result);
    >>> `{
      hosts: [{ host: 'localhost', port: 27017 }],
      hostname: 'localhost',

Properties

MongoDB connection model is based on Ampersand.js framework and consist of props and derived props. The props object describes the observable properties that MongoDB connection model gets from the Node.js Driver API.

const с = new Connection();
const props = с.getAttributes({ props: true });

Derived Properties

Derived properties (also known as computed properties) are properties of the state object that depend on other properties to determine their value.

const c = new Connection();
const derivedProps = c.getAttributes({ derived: true });
