Improving the Yeoman Generator Gulp Angular

David Barreto6 Comments

The Yeoman generator generator-gulp-angular is a great tool for building AngularJS and in my opinion is much better than the official Yeoman generator for AngularJS (generator-angular), because it uses Gulp and not Grunt as the task runner, it has a component-like folder structure for the code instead of the “drawer” style, it uses libsass instead of compass (ruby), it supports Typescript and has a lot of options for configuration.

But there is a thing that I don’t like: how it handles bootstrap-sass.

Working with Sass, Bootstrap and Gulp

David Barreto45 Comments

For frontend developers, the days when you manually linked css files to your index.html are over. Modern workflows needs some compilation steps before having a css file that can be use in development or production. Most notably, sass has become the most important language that extends css functionalities, while gulp has won the battle on the building tools front.

Introduction to the Typescript Transpiler

David Barreto1 Comment

Typescript is the new kid on the block, a newly attempt to bring order to the javascript chaos. ES6 is around the corner and is a fantastic step forward for frontend development (classes!) but it will take years to be fully implemented in all major browsers. That’s when Typescript comes to the rescue. Typescript goal is to be a superset of ES6 that, in addition to all the new stuff that the standard is defining, will add a static type system. Typescript has also a transpiler that converts our Typescript code (i.e. ES6 + types) to ES5 or ES3 javascript code so we can use it in today browsers.

Abstract/Concrete Inheritance Model in AngularJS

David BarretoLeave a comment

In a previous post I showed how to create a “classic” inheritance model in AngularJS using directives. This time I will show another inheritance model: the abstract/concrete.

In OOP, an abstract class cannot be instantiated, it serves only to provide common properties and functionality to child classes. In Angular, we have to make an analogy and define that an abstract directive is one that does not have a template or a link function, only a controller. The template is provided by child directives.

Directive Inheritance in AngularJS

David Barreto13 Comments

Inheritance is a powerful way to extend directives functionality and at the same time, improve code reuse. Lets see how it works in Angular with a simple example. The first step is to create a directive called “outer” which is going to be our top-level directive in our hierarchy.
