Asynchronous JavaScript execution in Vaadin Flow
Web applications built entirely in Java. That promise holds true when core Vaadin Flow components and browser APIs are enough. However, if you’re creating custom components or using modern asynchronous browser APIs, you’re likely to encounter a very different kind of “Promise.” JavaScript's ...
Testing Vaadin applications and add-ons using Playwright
Playwright is a browser automation tool similar to Selenium (WebDriver). These tools can be used as such to implement end-to-end tests that simulate actual user actions through the browser. Often, those are used through higher-level testing libraries such as Vaadin TestBench (built on top of ...
Embedding Vaadin Flow apps in a React-based web app
In my recent blog post, I discussed wrapping a component implemented with React in a Vaadin application. A greatly undervalued way to use Vaadin is by implementing only certain functions or parts of your web app or website. In that case, we are essentially doing the opposite: wrapping a Vaadin ...
