I was delighted to see the game generated so much interest, many people expressed an interest in the how we deployed the app on the cloud and that’s the motivation for this blog.

This blog is aimed at people who are experienced in developing desktop R scripts and have a desire to take the next step to create a Shiny app and deploy on the cloud.\nThe premise of our app was simply to act as a hook to encourage attendees to visit the Exploristics stand and learn more about the products and services we offer.

Without the years of effort and innovation from these individuals I would not have been able to deliver the app within our timescales. Any difficulty I faced on my part is not a criticism of these individuals but rather my experience under extremely tight time constraints that resulted in a limited amount of time to research appropriate solutions."

     "text": "How should I structure my code?\nThere are multiple ways to structure the files of a Shiny application and deciding which is the best often comes with experience or researching the best approach based upon your use case. I’d previously had the privilege of presenting along with Colin Fay at the Jumping Rivers Shiny in Production Conference and have read his book Engineering Production Grade Shiny apps but had never formally used the golem 📦. This provided me an opportunity to test out this framework and bring any lessons learnt into other Shiny apps.\nUsing the golem 📦 package for the first time was a delight, it created much of the boiler plate code for the application, provided functions to carry out common tasks and laid out the process in a systematic order to follow. This enforced good practice such as modularization of code and enabled me to rapidly write production quality code. I’ve previously developed production grade Shiny apps and was already very familiar concepts such as Shiny modules. I’d really recommend reading Colins book as it articulates and conceptualizes many of the issues I have faced. My biggest take home message from the book is – “Don’t jump straight into coding!”"

     "section": "How do I store and retrieve data?",
     "text": "How do I store and retrieve data?\nShiny apps are transient by design and sessions don’t persist.  This means that all information is lost between using the app. Therefore, if you wish to store information that the app needs to access in the future or provide a central data store you need to provide your own persistent data storage. There’s a great article on Posit for doing providing persistent data storage. For someone used to working on a desktop computer this is an unusual concept as you always have access to your hard-drive and by in large don’t need to worry about access.\nUsually, we use AWS S3 as our storage solution, but we didn’t want set up and manage access credentials for a one off project so decided to use Googlesheets as it was well documented and the package was actively developed. Whilst we got this to work locally, we could not get the authorization to work on Shinyapps.io and so decided to use rdrop2 📦 instead.\nThe rdrop2 📦 has no maintainer on CRAN so we had some initial reservations and we had to write some custom functionality to have refresh-able credentials. This cost us over a day’s development time which in the timescales of our project was huge!\nGoing forward we will assess the Pins 📦 or use AWS S3, though the AWS solutions is not be suitable for people wanting to avoid a paid for service, although it has a free tier with limited usage."

     "text": "Failure to build….what do you mean!?\nWhen working with an application, it’s a very iterative process and when you are inexperienced with the technology or rushing this can lead to lots of simple mistakes. Within a Shiny application this can mean the package fails to build, or a failure at the deployment stage or the application crashing when in use. This can be a frustrating process to those not used to it as it can take several minutes to go through these processes before realizing you’ve just nested a bracket in the wrong place!\nThis can lead to taking shortcuts in manual testing of an application which allows bugs to creep in and only manifest when in production. Structuring your application as a package allows you to leverage resources such as unit testing using testthat 📦 or shinytest2 📦 and automate the testing process, saving time and enforcing that these tests are carried out.\nIn this project, I often found that I would add a package on my computer but forget to add it to the DESCRIPTION file, this would result in the package not being accessible to the app on Shinyapps.io and failing to build and deploy. To the uninitiated this can be a frustrating experience as identifying the issue often takes much longer than implementing a solution."

     "text": "But it works on my machine!\nAnother issue that is conceptually different for those used to developing on the desktop is that different environments can result in an app working on your computer but not in the cloud. This is a very common occurrence in software development which can arise from having different or missing environment variables or the file system being different.\nOne issue that I had was that the setting of options required for the “gargle” package were silently being dropped when deployed on Shinyapps.io . This mean that locally I could get security tokens to work but they were failing on Shinyapps.io. This was a difficult issue to identify especially as the interactive debugging methods on a desktop can’t be used on a cloud-based environment. This requires the use of the logs to identify the issue."

Different people will have a range of IT abilities or understanding of terminology. This often leads to the application being used in a way you hadn’t anticipated, or they hit an unusual use case from a scenario that your testing hadn’t encountered.\nWhen testing the game I’d only played from start to finish and then redeployed with subsequent changes. What I hadn’t realized was that my application had state, I’d reset the user details after each game but not the deck of cards.  Effectively this meant a single deck of cards was used across games and eventually there were no more cards to draw from the deck – and this caused the game to crash.\nI really enjoyed making the Exploristics Higher or Lower app and I hope everyone enjoyed playing it too. Hopefully the lessons learnt by me will help you on your journey to creating interactive tools for your clients!\nFollow Exploristics on Twitter or LinkedIn to get the latest updates clinical trail simulation, interactive data visualization and the"

 I've found software development is a very risk averse industry. Requirements are gathered up front and making a seemingly simple change can have cascading effects on the software which leads to individuals wanting to work within very defined boundaries.
