Implementing State Machine On Eloquent Model*

* Update (12.09.2017): I have improved the trait so that it can be used with objects other than Eloquent Models.

Some days ago I came across a task where I needed to implement managable state for an Eloquent model. This is a common task, actually there is a mathematical model called "Finite-state Machine". The concept is that the state machine (SM) "can be in exactly one of the finite number of states at any given time". Also changing from one state to another (called transition) depends on fulfilling the conditions defined by its configuration.

Practically this means you define each state that the SM can be in and the possible transitions. To define a transition you set the states on which the transition can be applied (initial conditions) and the only state in which the SM should be after the transition.

That's the theory, let's get to the work.

This is the workflow I really love with Less that's missing in Sass. Killer way to use a library like Bootstrap without coupling any of your markup to Bootstrap itself.

Import a bunch of vendor styles by reference only, mix in the classes you want to keep into your own aliases, no vendor class names end up in your compiled CSS.

Sass doesn't support reference import or the ability to mixin a class, only a mixin.

// Vendor less
.btn {
 // a bunch

 * Responsive helper classes for Bootstrap style margins, padding, aligning, and displaying per screen size.
 * Works along with Bootstrap3.
 */

//== Media queries breakpoints from Bootstrap3

// Extra small screen / phone

export class EnumSymbol {
    sym = Symbol.for(name);
    value: number;
    description: string;

    constructor(name: string, {value, description}) {

        if(!Object.is(value, undefined)) this.value  = value;
        if(description) this.description  = description;

# Storing a Backbone.Model in localStorage

# You can then use localStorage as a collection. For an usage example, see

# This largely Just Worked™ for my needs. YMMV!
