This book is the result of an amazing amount of work, knowledge, and perseverance from many people. A big thanks goes to the entire team at Packt who made this book a reality, from the editors to the project coordinator; in particular, I would like to thank Rebecca Youé and Sriram Neelakantan for their guidance and patience during the toughest parts of the writing process. Kudos to Alan Shaw, Joel Purra, and Afshin Mehrabani who dedicated their time and expertise to reviewing the technical content of the book; every comment and advice was really invaluable in bringing this work up to production quality. This book would not exist without the efforts of so many people who made Node.js a reality—from the big players, who continuously inspired us, to the contributor of the smallest module.

In these months, I also learned that a book is only possible with the support and encouragement of all the people around you. My gratitude goes to all my friends who heard the phrase "Today I can't, I have to work on the book" too many times; thanks to Christophe Guillou, Zbigniew Mrowinski, Ryan Gallagher, Natalia Lopez, Ruizhi Wang, and Davide Lionello for still talking to me. Thanks to the D4H crew, for their inspiration and understanding, and for giving me the chance to work on a first-class product.

Thanks to all the friends back in Italy, to the legendary company of Taverna and Centrale, to the lads of Lido Marini for always giving me a great time, laughing and having fun. I'm sorry for not being present in the past few months.

Thanks to my Mom and Dad, and to my brother and sister, for their unconditional love and support.

At last, you have to know that there is another person who wrote this book along with me, that's Miriam, my girlfriend, who walked throughout this long journey with me and supported me night and day, regardless of how difficult it was. There's nothing more one could wish for. I send all my love and gratitude to her. Many adventures await us.
