Vaadin Flow 7.0.0.beta4

Changes in Flow from 7.0.0.beta3

• New Features:

  • ⧉ Implement HasStyle in LitTemplate so you can add class names to the root element (#10903). PR:11016

    Makes it possible to use addClassName("hello") in the constructor. Class for the custom element cannot be added in the template.

• Fixes:

  • ⧉ Use regular string enum instead of a const enum (#10853). PR:10860
    Given a Java enum as

    pubic enum Environment {
      DEV, TEST, PROD
    }

    Now it is possible to do any object action with the final Environment enum on the client-side:

    Object.keys(Environment).forEach(enumValue => console.log(enumValue));

  • ⧉ Remove old router layouts content before navigation (#10973). PR:11007. Ticket:345

    Recursively removes content of the all nested router layouts of the given old content when the navigation occurs. This is needed to let Dependency Injection frameworks (Spring and CDI add-ons) to re-create managed components with no duplicates/leftovers.

  • ⧉ Change construct-style-sheets-polyfill to be a runtime dependency (#10991). PR:10994. Ticket:10988

  • ⧉ Update the used Opcode from 7 to 8 (#10979). PR:10982. Ticket:10870

    Update used ClassVisitor ASM version from 7 to 8 to support Java16 record

  • ⧉ Use IOUtils toStream and toString (#10975). PR:10976. Ticket:10893

    Use IOUtils toString and toInputStream to not change any characters in the file content.

  • ⧉ Enable use of external css using @import (#10953). PR:10961. Ticket:10228

    Add fix for using a external css file by having the @import url(...) in a css file. Also supports imports with media queries.

  • ⧉ Use defined version for devDependencies. (#10955). PR:10958

  • ⧉ Allow empty segments at start (#10921). PR:10935. Ticket:10729

  • ⧉ Pin platform transitive dependencies with npm (#10864). PR:10920. Ticket:10572

    Uses the same vaadin_versions.json file based pinning as with pnpm. In case the application has @NpmPackage annotation with a certain version, then that is used over the platform pinned version. When that is older, a warning is logged (like with pnpm). In case a dependency has been pinned directly in package.json, then that is used over the platform pinned version. When that is older, a warning is logged (like with pnpm).

  • ⧉ Log limitation of adding new styles while switching themes (#10894). PR:10927. Ticket:10680

    If there are more than one theme available in themes folder, user can switch between them in development mode by changing the name of the theme in @theme. As having a watch for adding new styles in component folder is 'static', at least a log about this limitation is needed.

  • ⧉ Include flow-dnd module to flow-bom (#10911). PR:10914

  • ⧉ Upgrade to LitElement 2.5.1 and lit-html 1.4.1. PR:10912

• ⧉ All changes
