Inject Decorator

Create decorators that can inject anything into your JS modules!

Example using DOM elements

Define an object that represents some dom elements, call the library with it, and then use it to decorate a class as shown below. Elements are attached to $ of the class.

// part 1
import inject from 'inject-decorator'

const domElements = {
  heading: document.getElementById('heading'),
  footer: document.querySelector('footer')
}

export default inject(domElements)

// part 2
import dom from './dom'

@dom('heading')
class Hello {
    constructor (text) {
        this.$heading = Hello.$.heading
        this._displayDomElements(text)
    }

    _displayDomElements (text) {
        this.$heading.innerHTML = text
        this.$heading.style = 'display: block'
    }
}

To inject more elements than just heading, simply comma delimit i.e. @dom('heading', 'footer'). Or if you want access to all elements, use @dom without any arguments.
