When you launch Judoscale for the first time, you'll be prompted to install an "adapter" that's specific to your app's language and framework. In the adapter installation modal, select "Node" for your language and "ExpressJS" for your framework.
Based on your selections, you'll see instructions for installing the correct package and integrating it with your application.
Once you've committed and deployed these changes, click the button at the bottom of the modal to verify your adapter setup.
Once verified, the modal will close, and Judoscale will begin collecting throughput and request queue time metrics.
Note that autoscaling is still turned off. You'll want to review your configuration before enabling autoscaling.
