Change detection at face value is the act of determining if something is the same as it was at a previous time. In the case of this article, the thing that has changed is a web browser's Document Object Model (DOM) and the detection is done by Angular 2. This is an important feature of any web application's view layer and Angular 2 provides developers with many performant and useful tools for detecting change.
In part 1 of this series we defined a QuoteComponent that displays a random quote on a web page. We showed how to use Angular 2's testing utilities to mock out QuoteService and test the QuoteComponent's presentation logic in isolation.
Among the many new and exciting features of Angular 2 comes a robust and completely integrated testing module based off of the Jasmine testing framework.
Rangle's Sr. Talent Manager, Avery Francis, had the opportunity to spend the evening surrounded by brilliant women and men as they listened to thought leaders in the industry challenging the conversations, perceptions and stereotypes around women...
A few weeks ago Rangle had the privilege of being the first official Women in Software Sponsor for UofT Hacks, a student-run hackathon with over 500 participants chosen from thousands of applicants. The event was a huge success, with Rangle participating in the career fair, as mentors for the students, gathering feedback from students on their experience in the industry so far, and holding an entirely woman organized, led, and staffed professional development panel. Our ultimate goal was to find out more about what the computer science student experience is like, and through that, how we can help foster success with new graduates - especially those who identify as women.
Now that Angular 2 is in beta, one of the more interesting questions at hand is how can we migrate existing Angular 1.x applications into Angular 2? Fortuntely, the Angular development team have thought about this same question and have introduced the upgrade module as a way to help seamlessly upgrade your application. In this blog post, we'll explore how to downgrade and upgrade components and services from Angular 1.x to Angular 2 and vice versa!
The web developer's ecosystem has shifted dramatically over the last few years, and this has created opportunities for new approaches to mobile development. The Ionic framework from Drifty Co is a great example of this. Ionic came late into the hybrid-mobile-app development game, but it almost immediately found it’s place as a leader in the industry and is now almost synonymous with mobile HTML5 development for many people.
This post was last updated 02/09/2016. One of the features that made Angular 1.x a great tool for developers was how it simplified working with forms. Angular 2 builds on the strong foundation of Angular 1.x and provides even better tools for working with forms and validation. In this blog, we'll take a closer look at some of these upgrades. Also, stay tuned for two other posts in this series that will cover Directives and Observables.
