Engineering Production-Grade Shiny Apps

Application presentation

This book uses a series of applications as examples.

{hexmake}

hexmake is an application that has been designed to build hex logos. It was built by Colin, and it serves two main purposes: it helps the creation of a logo, but mainly it serves as an example of some complex features you can use inside a shiny application (image manipulation, custom CSS, linking to an external database, save and restore, etc.).

{tidytuesday201942}

tidytuesday201942 is an application using the dataset from week 42 of tidytuesday 2019. It was built by Colin, and it serves as an example of an app built from scratch using bootstrap 4.

{minifying}

{minifying} is an application to minify CSS, JavaScript, HTML, and JSON files. It was built by Colin as a use case for the workflow of this book. You will find the details of how this app was constructed in the Appendix, “Use case: Building an App, from Start to Finish”.
