Running a new Vaadin 14.0.8 app in IntelliJ Ultimate 2019.3 EAP pre-release, on Java 13. I created the project using the "Plain Java Servlet" flavor on the new project page. The only change I made to the POM was adding the npm/Node plugin as described in this Answer.
When I run my web-app using the jetty:run
item in the Maven panel, I get these messages on the console:
[webpack] INFO dev-webpack - Watchdog connection closed. Trying to re-run watchdog.
[webpack] INFO dev-webpack - Watchdog connected.
These repeat every minute or so, even before connecting with a browser. When I do connect with a browser, I get another four of these repeated.
➥ What do these messages mean? Is there a problem?
➥ Why so many?
