Web Interface to 'R' Functions

Web front end for your 'R' functions producing plots or tables. If you have a function or set of related functions, you can make them available over the internet through a web browser. This is the same motivation as the 'shiny' package, but note that the development of 'shinylight' is not in any way linked to that of 'shiny' (beyond the use of the 'httpuv' package). You might prefer 'shinylight' to 'shiny' if you want a lighter weight deployment with easier horizontal scaling, or if you want to develop your front end yourself in JavaScript and HTML just using a lightweight remote procedure call interface to your R code on the server.

ShinyLight

A lightweight server for R calculations.

This project was funded by the Natural Environment Research Council (grant number 09 NE/T001518/1 ("Beyond Isoplot")).

Building ShinyLight

To rebuild documentation and reinstall the local version of ShinyLight:

./build.sh

Run tests

npm test

or

npm test -- --fgrep 'test that I want' --browser=chrome

Run CRAN checks

./build.sh
R CMD build .
_R_CHECK_FORCE_SUGGESTS_=true _R_CHECK_CRAN_INCOMING_USE_ASPELL_=true R CMD check --as-cran shinylight_<VERSION>.tar.gz

Troubleshooting

ERROR: dependency 'xxx' is not available for package shinylight

Sadly, build.sh does not install dependencies based on what's in the DESCRIPTION file. Until this is fixed, make sure that the hard-coded list of dependencies in the build.sh file itself is up-to-date.

InvalidArgumentError: binary is not a Firefox executable

On Linux, having firefox installed as both a snap and via apt causes this. Try sudo apt remove firefox.

In Selenium tests, "before each" hook: WebDriverError: Reached error page

Try running the test server on its own with Rscript test/run.R and see what errors you get.
