Terminologies

  • Model: An object that holds data, e.g. configuration, customer information, etc.
  • attributes: The actual data in plain object, which is fed to the Model during construction.

Usage

Let's import the necessary function from the library first:

import { createModel } from 'frint-model';

Now we can create our Model:

const Shirt = createModel({
  getColor: function () {
    return this.get('color');
  },
  getSize: function () {
    return this.get('size');
  },
});

Building a new model instance object:

const shirt = new Shirt({
  color: 'blue',
  size: 'medium',
});

const color = shirt.getColor(); // blue
const size = shirt.getSize();   // medium

The model instance can also be observed for changes:

shirt.get$().subscribe(function (shirtAttributes) {
  // triggered when the model had any change
});

shirt.get$('color').subscribe(function (color) {
  // triggered when the model's `color` key changes
});
