Basic usage

Create values

import { Color, Email, Hour, PositiveNumber } from '@haskou/value-objects';

const email = new Email('user@example.com');
const color = new Color('#FF0000');
const startAt = new Hour('09:30');
const quantity = new PositiveNumber(3);

Read primitive values

email.valueOf(); // 'user@example.com'
email.toString(); // 'user@example.com'
quantity.valueOf(); // 3

Compare by value

const a = new Email('user@example.com');
const b = new Email('user@example.com');

a === b; // false
a.isEqual(b); // true

Use helpers

const nextSlot = new Hour('23:30').addMinutes(90);
nextSlot.toString(); // '01:00'

const id = UUID.generate();
id.toString();

Handle invalid input

import { Email, InvalidEmailError } from '@haskou/value-objects';

try {
  new Email('nope');
} catch (error) {
  if (error instanceof InvalidEmailError) {
    // Handle invalid email input.
  }
}
