test graceful shutdown
git clone
npm install
npm run start
To kill server, in console where it was started, use Ctrl-C
Scenarios to test:
- Just let it start, then kill, and observe logging.
- Start a request in one browser, kill server, observe
- Start a request in one browser, kill server, start a request in a second browser
- this should allow first request to complete, second get a 503 error, then shutdown when first request completes
