Introduction

This book is currently under development. It will be published in 2020 in the R Series by Chapman & Hall.

Motivation

This book will not get you started with Shiny, nor talk about how to deploy into production and scale your app. What we’ll see is the process of building the app. Why? Lots of blog posts and books talk about starting to use shiny or putting apps in production. Very few (if any) talk about this grey area between getting started and pushing into production.

So this is what this book is going to talk about: building Shiny application. We’ll focus on the process, the workflow, and the tools we use at ThinkR when building big Shiny Apps.

Hence, if you’re starting to read this book, we assume you have a working knowledge of how to build a small application, and want to know how to go one step further.

Book structure

  • Part 1 (Building big Shiny Apps) gives a general context about what is a successful Shiny Apps and what challenges arise when you’re dealing with a large scale application. It also introduces the {golem} package and more general concept about organising your workflow. This first part will be light on code: you’ll read more about conceptual ideas and organisation strategy.

  • Part 2 to 6 describes a series of steps you can take when you want to build a Shiny App, and the tooling associated with each step.

  • Part 7 (Optimizing) tackles the question of optimization, first by presenting some common caveats of Shiny Apps, and then showing how to optimize R code, and use JavaScript to lighten R work.

Any feedbacks on the book is very welcome. Feel free to open an issue, or to make a PR if you spot a typo (I’m not a native english speaker, so there might be some waiting to be found ;) ).
