Let's start the application to view the generated pages. In the Terminal, execute the Gradle command, as follows:
> ./gradlew
This will start the server in development mode locally. Since the import-jdl step already compiled the frontend code, we don't have to run npm start just to see the new pages, but please note that for further development, it is better to use npm start along with the preceding command. If you had the server already running while generating the entities, then there is no need to run this command; instead, just compile the source again using the ./gradlew compileJava command or using your IDE and Spring DevTools will hot reload the application for you. If you had npm start running, then a hot reload will take place on the client-side as well; otherwise, just refresh the page. We will learn more about hot reloading in the next chapter...
