This is a project for testing approaches to translating strings in Vaadin Fusion. The approach here uses lit-translate.
The reasoning behind this choice is that it's easy to customize how the strings are loaded, and it integrates well with Lit.
This project stores translations in a standard resource bundle (src/main/resources/messages_<lang>.properties). The translations are converted to a JSON object and served to the client
through the TranslationEndpoint.
On the client, the translate directive from lit-translate is used, in order for components to be updated once the language changes.
The language is set in the main-layout.ts through the app-store.ts. The choice is currently not persisted across browser reloads.
The project is a standard Maven project. To run it from the command line,
type mvnw (Windows), or ./mvnw (Mac & Linux), then open
http://localhost:8080 in your browser.
You can also import the project to your IDE of choice as you would with any Maven project. Read more on how to set up a development environment for Vaadin projects (Windows, Linux, macOS).
