Mohite Technical Editor Cover Work Mohita Vyas Nilesh R. Mohite Copy Editors Roshni Banerjee Akshata Lobo About the Author Pablo Deeleman is a former UX designer and frontend engineer who discovered the Web back in the 90s, when a 14,400 bps modem was the key to an unparalleled world of marvels and a build-your-own-website was the name of the game. After getting his BA (Hons) degree in marketing and moving through different roles in the advertising arena, he took his chance and evolved into a self-taught, passionate UX designer and frontend developer with a crunch for beautifully crafted CSS layouts and JavaScript thick clients, having produced countless interactive designs and web desktop and mobile applications ever since. During these years, he has fulfilled his career as both an UX designer and frontend developer by successfully leading Internet projects for a wide range of clients and teams, encompassing European online travel operators, Silicon Valley-based start-ups, international heavy-traffic tube websites, global banking portals, or gambling and mobile gaming companies, just to name a few. At some point along this journey, the rise of Node.js and single-page-application frameworks became a turning point in his career, being currently focused on building JavaScript-driven web experiences. After having lived and worked in several countries, Pablo Deeleman currently lives in Barcelona, Spain, where he leads the frontend endeavor in the Barcelona studio of Gameloft, the world leader in mobile gaming, and the home of internationally acclaimed games, such as Despicable Me: Minions Rush and Asphalt 8. When not writing books or taking part in industry events and talks, he spends most of his time fulfilling his other passion: playing piano and guitar. Acknowledgments The book you hold in your hands right now is the result of a lot of time, effort, and sacrifice. Someone wisely said once that writing a book about a framework in the alpha stage is like aiming at a moving target, and indeed it is. During the writing, the author and the team involved in this project wound up losing track of how many times we had rewritten everything to conform to the latest incarnation of the framework. In the heat of the battle, it is quite easy to fall under the weight of frustration and seriously consider whether such a project is worth the effort or not. In that sense, this is why I only have words of appreciation for the team at Packt and most particularly for Samantha Gonsalves. Her kind words of support fueled the energy I needed to move this project ahead. I would also like to specially thank my friend and tech author Jorge Ferrando for his guidance and hints during the production process for this book. His expertise in Angular 2 became priceless when assessing the different courses of action to deliver the best learning experience. A mention is required as well for our other fellow developers Javier Gómez, Alfonso Fernández, Fran Iruela, and Pedro Narciso. I'd like to also thank the people who have mentored me and accompanied me along this professional journey over these years, with a special mention for the people at Casumo and Gameloft, and most specifically and in no particular order, for Razmus Svenningson, Kim Larsen, Josef Galea, Steve Attard, Iden Azzopardi, Renald Dalli, Matthew Borg, Mark Busuttil, Gerard Giné, Antonio González, Albert Puértolas, Rafael Marfil and the always inspiring Stuart Langridge.
