We've built a simple Rails app that demonstrates LaunchDarkly bootstrapping.
We modified and/or added the following files to create this example:
- app/views/hello_world/index.html.erb
- app/controllers/hello_world_controller.rb
- config/puma.rb
Rails created the rest of the files and they are unmodified.
Below, you'll find the build procedure. To learn more about the Ruby SDK, read the Ruby SDK reference.
Make sure you have Ruby installed. Then, clone the repository, set the LD_SDK_KEY and LD_CLIENTSIDE_ID environment variables, and start your local server. Here's how:
$ git clone [email protected]:launchdarkly/hello-bootstrap-rails.git # or clone your own fork
$ cd hello-bootstrap-rails
$ export LD_SDK_KEY=YOUR-SDK-KEY
$ export LD_CLIENTSIDE_ID=YOUR-CLIENTSIDE-ID
$ bundle install
$ bin/rails db:migrate
$ bin/rails serverYour app should now be running on localhost:3000.
Your app should display a JSON representation of all flags in the project and environment associated with your SDK key and Client-side ID, with the values served for both the normal client and the bootstrapped client for the example user context.
