## Build instructions

1. Install the LaunchDarkly Node.js SDK by running `npm install`
2. Edit `index.ts` and set the value of `sdkKey` to your LaunchDarkly SDK key. If there is an existing boolean feature flag in your LaunchDarkly project that you want to evaluate, set `featureFlagKey` to the flag key.
2. 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.

```js
const sdkKey = "1234567890abcdef";

const featureFlagKey = "my-flag";
```bash
export LAUNCHDARKLY_SDK_KEY="1234567890abcdef"
export LAUNCHDARKLY_FLAG_KEY="my-boolean-flag"
```

3. Run `npm start`

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