Getting Started

You can either add the required dependencies to an existing project or use one of the Maven archetypes to get started.

Maven dependencies

To create a linkki project, you need one of the following dependencies depending on the feature set you need:

linkki-core
            <dependency>
                <groupId>org.linkki-framework</groupId>
                <artifactId>linkki-core-vaadin-flow</artifactId>
                <version>2.4.9</version>
            </dependency>
linkki-vaadin-flow-component
            <dependency>
                <groupId>org.linkki-framework</groupId>
                <artifactId>linkki-vaadin-flow-component</artifactId>
                <version>2.4.9</version>
            </dependency>

linkki-vaadin-flow-component contains the following additional features:

  • Sidebar layout

linkki-application-framework
            <dependency>
                <groupId>org.linkki-framework</groupId>
                <artifactId>linkki-application-framework-vaadin-flow</artifactId>
                <version>2.4.9</version>
            </dependency>

linkki-application-framework contains the following additional features:

  • Dialogs

  • LinkkiUi with ApplicationLayout and ApplicationConfig as well as an adjusted theme

  • UI Components to display validation messages

In addition to the linkki dependency, a linkki application with Vaadin may require a Vaadin Spring Boot starter.

Maven Archetypes

linkki can be used for a plain Vaadin web application or with Spring Boot. For each of those options, there is a matching Maven archetype that creates a new project with all necessary dependencies and some sample code to get started. They can be created from a command line:

Plain linkki
mvn archetype:generate -DarchetypeGroupId=org.linkki-framework.archetypes -DarchetypeArtifactId=linkki-archetype-plain-application-vaadin-flow -DarchetypeVersion=2.4.9

The resulting application can be deployed to your application server of choice or simply started with mvn clean package org.eclipse.jetty:jetty-maven-plugin:run, where it can be viewed at http://localhost:8080/.

linkki with Spring Boot
mvn archetype:generate -DarchetypeGroupId=org.linkki-framework.archetypes -DarchetypeArtifactId=linkki-archetype-spring-application-vaadin-flow -DarchetypeVersion=2.4.9

The resulting application can be started with java -jar target/*.jar and be viewed at http://localhost:8080/.

Initial project structure

app structure
BusinessPartner

A spring specific class which allows our project to be run as a Java application. This class will not be found in the plain archetype.

BusinessPartnerInfo

Defines basic information about our linkki application.

BusinessPartnerConfig

Provides an instance of our BusinessPartnerInfo class and provides ApplicationMenuItemDefinition items to create an ApplicationMenu for the ApplicationHeader.

BusinessPartnerLayout

Uses the BusinessPartnerConfig class to provide information for our application.

HelloPmo

Defines a section on the webpage which is used in the UI of the application. You can apply annotations like @UITextfield to your methods to create specific UI elements. For more information about creating a UI see UI elements.

BusinessPartnerPage

Allows displaying and editing data in a certain layout and can consist of so called sections defined with multiple PMOs.

BusinessPartnerView
