Make a code change
While the app is still running, open the file sam-app/hello-world/app.js and make a simple code change. For example, change the response message to return hello my friend instead of hello world. Your Lambda handler should look like this after the change:
Note: Make sure you save the file after changing it.
You don’t have to restart the sam local process, just refresh the browser tab or re-trigger the CURL command to see the changes reflected in your endpoint.
You only need to restart sam local if you change the template.yaml.
