LaunchDarkly Lua server-side SDK basic example

First, modify hello.lua to inject your SDK key and boolean-type feature flag key.

Then, use the Lua interpreter to run hello.lua:

lua hello.lua

If you'd rather use environment variables to specify the SDK key or flag key, set LAUNCHDARKLY_SDK_KEY or LAUNCHDARKLY_FLAG_KEY.

LAUNCHDARKLY_SDK_KEY=my-sdk-key LAUNCHDARKLY_FLAG_KEY=my-boolean-flag lua hello.lua

The program should output:

The (flag key) feature flag evaluates to (true/false).
