Model

• Tiny Unminified filesize is ~350 bytes
• Extensible Its a small class that you can easily extend with ES6
• Easy to use Simply call getters & setters

Notice

Be aware, this project is only written for ES6+ clients at the moment.

For a list of supported browsers, check the mdn browser compatability list for ES6 classes

If you require any eventing etc, you can extend the class & bake in your own events, or try out another model system (backbone-model is avaliable as a standalone module on npm)

API

ES6

// Import the dependency
import Model from '@jakejarrett/model';

// Initialize the model with some values
const MyModel = new Model({ username: 'jake', id: 0 });

// Get the current username
MyModel.get('username'); // returns "jake"

// Lock the current state of the model
const model = MyModel.freze();

// Updates the model
MyModel.set('username', 'not jake');

// Model & frozen model are not the same
MyModel.get('username') === model.username; // False

Documentation

get

The get function takes a string parameter.

It returns either undefined if the value could not be found, or the value you stored under that key.

MyModel.set('hello', 'world')

// Returns 'world'
MyModel.get('hello')

set

The set value takes 2 paramaters

The first being a string parameter, which is used for the get lookup.

The second being any type you wish to set.

MyModel.set('hello', {
    world: {
        nested: 'objects'
    }
});

freeze

A simple function that returns a "frozen" object (Think diverged)

Useful for state comparison & preventing mutation of your object reference

MyModel.set('user', { name: 'jake', id: 0 });

const divergePoint = MyModel.freeze();

MyModel.set('user', { name: 'not jake', id: 1 });

// Will fail
MyModel.get('user').name === divergePoint.user.name;

isNew

A simple function to check if the model is new (the existence of the id attribute)

MyModel.isNew(); // true

MyModel.set('id', 0);

MyModel.isNew(); // false
