LaunchDarkly sample R server-side application

We've built a console application that demonstrates how LaunchDarkly's SDK works. Below, you'll find the basic build procedure. While LaunchDarkly does not have a dedicated R SDK, you can use the Python SDK. Use this as a starting point for integrating the python-server-sdk with your R application. To learn more, read the Python SDK reference guide.

Dependencies

1. Install the reticulate package: R -e "install.packages('reticulate')"
2. Install the LaunchDarkly Python SDK: pip3 install launchdarkly-server-sdk

Build instructions

1. Set the environment variable LAUNCHDARKLY_SDK_KEY to your LaunchDarkly SDK key. If there is an existing boolean feature flag in your LaunchDarkly project that you want to evaluate, set LAUNCHDARKLY_FLAG_KEY to the flag key; otherwise, a boolean flag of sample-feature will be assumed.

   export LAUNCHDARKLY_SDK_KEY="1234567890abcdef"
   export LAUNCHDARKLY_FLAG_KEY="my-boolean-flag"

2. On the command line, run Rscript main.r

You should receive the message "The feature flag evaluates to .". The application will run continuously and react to the flag changes in LaunchDarkly.
