Module flamingo-carotene-behavior

The behavior Module is a "DOM-aware" component loader, which loads js-classes automatically and attaches them to dom-elements.

How to use

npm i -D flamingo-carotene-behavior

See 'How to initialize' below.

What it is for

Given, you've got a DOM structure like this:

<div>
    <h1>Click here to see the collapsible content</h1>
    <div class="content">Content of the collapsible</div>
</div>

And you want to add some javascript behavior to the headline element to toggle visibility of the content element.

Simply add "data-behavior"-attribute to the element group

<div data-behavior="collapsible">
    <h1>Click here to change the collapsible content</h1>
    <div class="content">Content of the collapsible</div>
</div>

After that, create an ES6 class with the name of the data-attribute (in that case "collapsible")

export default class Collapsible {

  constructor (element) {
    // your code here
  }

  dispose () {
    // your code here
  }
}

Note: The NAME of the class is important here! The DOM element with the data-behavior attribute is passed to the constructor of your class.

How to initialize

Initialisation is easy.

Load the behavior module

import Behavior from 'flamingo-carotene-behavior'

Loading your behaviors

  • Load all your behaviors with globbing (the babel-way)
import * as behaviorModules from './../../**/*.behavior.js'
  • Load all your behaviors with globbing (the webpack-way)
import behaviorModules from './../../**/*.behavior.js'
  • Load all your behaviors manually
import myBehavior from './foo/bar/myBehavior.js'
import anotherBehavior from './xxx/yyy/anotherBehavior.js'
const behaviorModules = {
  'myBehavior': myBehavior,
  'anotherBehavior': anotherBehavior
}

Create a behavior instance and pass your behaviors to the constructor

const behavior = new Behavior(behaviorModules)
behavior.attachBehaviors() 

Done!

Debugging

If you've got strange results or behaviors of the behavior module, it is worth to turn on debugging console messages. Simply add

behavior.setDebug(true)

after creating the behavior instance.
