I am indebted to my mother, Nithi, and my sisters, Shaila, Anshu, and Aastha, for their constant support. I am grateful to Aastha for helping me out with the images of this book.

A special thanks to my cousin Rohit for being there for me; he has guided, mentored, understood, and pampered me throughout. This book would not have been possible without his help. I would also like to thank his organization, Tuplejump.Inc, for giving me the idea of using real-time applications with Play Framework.

I'd like to thank Jay and Vijay Pullur for taking the initiative to start Pramati and everyone who's a part of it for making it a great place to work at.

I'd like to thank Apurba for believing in me and supporting me in my journey. I wouldn't have learned a lot of things if it wasn't for his guidance.

I'd also like to thank Guillaume Bort, Sadek Drobi, the Play Framework community, and Typesafe without whose efforts, bringing this technology to the forefront and writing this book wouldn't have been possible.

I am grateful to my friends for being there for me when I needed them.

A huge thanks to the team of Packt Publishing for coordinating and being patient with me when I wasn't able to meet their deadlines. I am also thankful to the reviewers, Didier, Jérôme, and Jon, for their valuable feedback, which has helped improve this book.

I would like to express my gratitude to everyone who has helped me reach this stage in my life. Thanks!
