Vaadin Flow and Component Java APIs Documentation

This is the documentation for Vaadin Flow, the new Java web framework available in Vaadin platform. It also contains documentation on the Java APIs for Vaadin's web components.

This documentation is available in vaadin.com/docs. Any issues and contributions can be added here, or in vaadin.com/docs via the report issues or edit page actions.

This branch is Vaadin 11 (Flow version 1.1) compatible. See other branches for other framework versions:

• master branch is for Vaadin 11 (Flow version 1.1)
• 1.0 branch is for Vaadin 10 (Flow version 1.0)

Structure

The documentation is split into the following modules:

• docs-helpers - sources for validating the code snippets to match the documentation
• tutorial-* - standalone tutorial projects that can be run individually
• documentation - the documentation files written in .asciidoc and tests

For verifying the changes made to the documentation, run mvn verify on the root level project.

Adding new tutorials

When a new tutorial is added, the end result should be included as a new module that needs to be built before the documentation module. The tutorial should use the @CodeFor("path/file.asciidoc") and @Helper annotations available from the docs-helpers dependency to map the source files to the tutorial code snippets in the documentation module.

Any added tutorial module can be included as a dependency to the documentation module, so that the code snippets from the documentation can be verified. This requires couple steps:

• For web app projects with war packaging:
  • the <appendClasses> configuration must be enabled for the maven-war-plugin
  • The dependency should be to documentation added with <classifier>classes</classifier>
• The TestTutorialCodeCoverage class needs to know the source folder location (see static variables)
