Getting Started with Vaadin

App starters

The best way to get started with Vaadin is to go to https://vaadin.com/start and pick an app template for the technology stack you’re interested in.

Note

Vaadin 20 starters are not available just yet in vaadin.com. You can use Vaadin 14 starter and manually change Vaadin version (see instructions below).

Manually changing Vaadin version for Java projects

Add the following contents to your project pom.xml. 

<dependencyManagement>
    ...
    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-bom</artifactId>
        <version>20.0.0.beta1</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
    ...
</dependencyManagement>

Known Issues and Limitations

This is the prerelease version of Vaadin 20 for evaluating a number of new features and bug fixes. The API in this prerelease version is not considered final and may change based on user feedback.

Flow

  • The Template-in-Template feature has some limitations
  • Links matching the context do not result in browser page load by default, instead they are handled with application routing. To opt-out, set the router-ignore attribute on the anchor element. This opt-out is needed for cases when native browser navigation is necessary, e. g., when using Anchor to link a StreamResource download.

Migrating from Vaadin 8

See the migration guide

Migrating from Vaadin 10-14

See the migration guide

Migrating from Vaadin 17

Update the Vaadin version in the build files, and check if the project is using any of the breaking changes mentioned in the 'New and Noteworthy' section above.
In addition, in the case of using the now deprecated PolymerTemplate in views, we encourage to migrate to LitTemplate.

Reporting Issues

We appreciate if you try to find the most relevant repository to report the issue in. If it is not obvious which project to add issues to, you are always welcome to report any issue at https://github.com/vaadin/platform/issues.

A few rules of thumb will help you and us in finding the correct repository for the issue:

  1. Bug tickets and enhancement requests that are specific to a certain Vaadin component should be posted in the component's Web Component repostory (e.g. https://github.com/vaadin/vaadin-button for Button).
  2. Issues that are not component-specific (e.g. requests for new components) or encompass multiple components should be posted in vaadin-flow-components repository.
  3. If you encounter an issue with Flow which does not seem to be related to a specific component, the problem is likely in Flow itself. The Flow repository is https://github.com/vaadin/flow
  4. If you encounter an issue with Designer, the repository is https://github.com/vaadin/designer
  5. If you encounter an issue with TestBench, the repository is https://github.com/vaadin/testbench
