Building Office Add-ins using Office.js
Building Office Add-ins using Office.js
About the Book
This book is about creating Office Add-ins – and in particular, about the new Office 2016 wave of Office.js APIs.
Want to get started with just the very core concepts, before buying the book? Download some sample chapters, or visit http://BuildingOfficeAddins.com, which contains abridged content for some of the key topics in this book. Or better yet, buy the book regardless: I am sure you'll find the topics therein new and useful for writing add-ins; and if you don't, LeanPub's Happiness Guarantee will let you get a full refund anytime in the first 45 days.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Office 2016 has seen a major re-birth of the API model, with hundreds of new APIs created for Excel and Word and OneNote. These APIs are cross-platform, are built on a modern web framework, and offer some of the same powerful functionality that previously was only available on the Desktop.
In spirit, the new Office.js APIs are reasonably similar to their VBA/VSTO counterparts, but with the notable difference of being async – which brings with it a new set of concepts and best practices. This book will begin by address the core concepts to help you get over the initial learning curve, and get started on using the APIs. The subsequent chapters will expand upon these topics, covering more advanced scenarios, and offering debugging advice, tips, FAQs, and so forth.
Note that this book is published using a "lean" methodology – publishing early, and publishing often. Since writing the book is strictly my "moonlighting" activity – my day-job is to be a developer on Office.js APIs, not a technical writer – it will take a good long while before I am actually done with all the content I want to write about. I would rather ship an early version of the book, addressing the most common questions and issues that I see folks struggling with, and then keep iterating on it from there.
In buying this e-book through LeanPub (where I’m also discounting it for the "early readers"), you are entitled to free updates to the book. So, expect to see more content appear month-to-month (and, if you sign up for email notification, to receive periodic emails updates about what new content got added).
I welcome any and all feedback about the writing, explanations, code-samples, and whatever else. I also welcome topic suggestions, if you see something I didn’t cover; or, if you see something that I plan to cover, but haven’t yet, just let me know and I can see if I can prioritize it.
Yours truly,
- Michael Zlatkovsky, the author
