Deploying our app
cdktn diff
Before we deploy, let's take a look at what will happen when we deploy our app
(this is just the Resources section of the output):
$ cdktn diff
cdk-workshop Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
cdk-workshop + create

Plan: 19 to add, 0 to change, 0 to destroy.You'll notice that the table viewer adds another API Gateway endpoint, a Lambda function, permissions, outputs, all sorts of goodies.

}You'll see the viewer endpoint as an output.
Viewing the hit counter table
Open your browser and browse to the hit counter viewer endpoint URL. You should see something like this:
Send a few requests
Send a few more requests to your "hello" endpoint and monitor your hit counter viewer. You should see the values update in real-time.
Use curl or your web browser to produce a few hits:
