Better to use Prototypal OO and not ES6 class (Angular example)
'use strict';
import _ from 'lodash';
// generate some list items
let items = _.times(10).map((n) => {
return {
title: `This is log item ${n + 1}`,
description: `This is item description ${n + 1}`
};
});
// ES6 classes are bad news due to inheritance hierarchies!!!
class Service {
constructor(LayoutService) {
this.LayoutService = LayoutService;
}
}
// sub-classes lead to arthritic code and brittleness due to rippling side-effects
class Controller extends Service {
constructor() {
// super is a code smell
super();
this.items = items;
}
}
/*
Better to use a factory function, here we use a delegate prototype
where LayoutService is also be a factory function
for details see @_ericelliot
*/
let controller = (LayoutService) => {
return Object.assign(LayoutService, {
items: items
});
};
// angular DI - just to show how it would work, export Controller will work her as well
export default ['LayoutService', controller];
