Exploring Angular 1.5 components: maximizing the potential of directives with ES6!

Question

Exploring Angular 1.5 components: maximizing the potential of directives with ES6!

Within the directory labeled directives, I have created two files: directives.js and color.js

I have imported directives into app.js

Contents of directives.js:

import angular from 'angular';

import ColorDirective from './color';

const moduleName = 'app.directives';

angular.module(moduleName, [])

  .directive('color', ColorDirective);

export default moduleName;

Contents of color.js:

import angular from 'angular';


let ColorDirective = function () {

  return {
    link: function (scope, element) {
      console.log('ColorDirective');
    }
  }

}

export default ColorDirective;

In one component, I have added color as an attribute to an element

However, it does not seem to be working. There seems to be an issue with the inner link loop. What could be coded incorrectly? How can I effectively use directives in Angular 1.5 & es2016?

It seems that the issue cannot be identified based on the information provided. The code you have shared appears to work, assuming that your module is correctly included in the page and the code is compiled properly.

I have created a fiddle with your code: https://jsfiddle.net/fccmxchx/

let ColorDirective = function () {
  return {
    link: function (scope, element) {
      console.log('ColorDirective');
      element.text('ColorDirective');
    }
  }
}

angular.module('app.directives', [])
  .directive('color', ColorDirective);

Unfortunately, I am unable to separate your code into modules as intended.

Although I'm not very experienced with es6 syntax, here is how I am currently implementing the directive in TypeScript:

class ColorDirective implements angular.IDirective {

    constructor() { }

    link(scope, iElement, iAttrs, ngModelCtrl) {
        // Implementation logic goes here
    }

    /**
    * Instance creation
    */
    static getInstance(): angular.IDirectiveFactory {
        let directive: angular.IDirectiveFactory = () => new ColorDirective();
        directive.$inject = [];
        return directive;
    }
}

angular
    .module('moduleName')
    .directive('color', ColorDirective.getInstance());

UPDATE: After conducting some research, I have discovered the es6 approach to achieve the same functionality:

import angular from 'angular';

class ColorDirective {

    constructor() {
        // Constructor implementation
    }

    link(scope, element) {
        console.log('ColorDirective');
    }

    static getInstance() {
        var directive = new ColorDirective();
        // Return instance logic
    }
}

export default ColorDirective.getInstance();
