You can run Nodejs such as react or angular on JavaPipe's Tomcat service. You will need to use npm run build to package the Nodejs for production. It creates a build folder where you can package it as a war file. cd into the build directory and then run jar cvf webui.war . Name the war file for the URL pathname and upload it to your tomcat webapps directory.
