A public Shiny app to monitor air quality in Belgium

This public service scientific institute had developed a shiny application to disseminate information on air quality. Over time, this application had become very large, and difficult to develop and maintain.

ThinkR was asked to transpose this tool into a shiny application developed with {golem} and respecting the standards of good development practices used at ThinkR (package development, use of modules, unit testing, etc.).

– Redesigning the app to use {golem}

– UX redesign

– Overhaul of business logic

– Use of modules, unit tests, documentation …

– Use of an internal package for the business part of the application

– Management of dependencies and their evolution via {renv}

– Creation of Docker images for application deployment

– An application for the general public on a public health topic

– An application respecting good development practices in R / {shiny}

– Easier to use, maintain and evolve

– Dockerization of the application in a container that can be deployed on a dedicated server
