Hot deploy configuration for Vaadin CKEditor component.

This class provides support for hot reloading during development. It is automatically registered via Vaadin's ServiceInitListener mechanism.

Hot Deploy Setup:

For Gradle projects using this addon:

// In build.gradle.kts of your application
vaadin {
    optimizeBundle = false  // Disable optimization for faster reloads
}

// Run with hot reload
./gradlew vaadinPrepareFrontend
./gradlew bootRun  // or your preferred run task

For Maven projects using this addon:

<!-- In pom.xml of your application -->
<plugin>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-maven-plugin</artifactId>
    <configuration>
        <optimizeBundle>false</optimizeBundle>
    </configuration>
</plugin>

// Run with hot reload
mvn vaadin:prepare-frontend
mvn spring-boot:run  // or jetty:run

IDE Configuration:

  • IntelliJ IDEA: Enable "Build project automatically" and "Allow auto-make to start even if developed application is currently running"
  • Eclipse: Enable "Build Automatically" in Project menu
  • VS Code: Use the Vaadin extension with auto-build enabled

JVM Options for Hot Reload:

// For Spring Boot DevTools integration
-Dspring.devtools.restart.enabled=true

// For faster class reloading with DCEVM/HotSwapAgent
-XX:+AllowEnhancedClassRedefinition
-javaagent:/path/to/hotswap-agent.jar
