shiny.router

A minimalistic router for your Shiny apps.

Now it’s possible to recreate a state of your app, by providing a specific URL, like:

make_router(
  route("<your_app_url>/main",  mainPageShinyUI),
  route("<your_app_url>/other", otherPageShinyUI)
)

Basic tutorial article is available on Appsilon Data Science blog.

Troubleshooting

We used the latest versions of dependencies for this library, so please update your R environment before installation.

However, if you encounter any problems, try the following:

1. Up-to-date R language environment
2. Installing specific dependent libraries versions

   • magrittr

     install.packages("magrittr", version='1.5') 

   • shiny

     install.packages("shiny", version='0.14.2.9001')

3. Missing semanticui dependency - one of our examples uses one of our others libraries, so please install it as well, when running that example. Repository: semanticui

Future enhacements

• URL params handling
• CRAN release
• consider utilising https://shiny.rstudio.com/articles/client-data.html instead of Page.js
