Time is a valuable resource... That's why I dedicated myself to creating this content with the time I had available. Should there be any discrepancies with the original sources, please consider my main goal: to contribute and help all readers. This article is part of the series 'Towards Vaadin Developer Certification,' which aims to explain the fundamentals of Vaadin as I study for this certification. The topics covered here are part of the 'Vaadin Developer' Certification curriculum. The content was created based on my personal notes and studies for this certification. Vaadin: A Democratic Framework Vaadin: A Democratic Framework When we expand our definition of "fields" beyond just input components, we discover one of Vaadin's most powerful features - its democratic approach to UI development. This framework allows you to integrate components from outside the Vaadin ecosystem seamlessly. Despite this openness, it's worth noting that Vaadin already provides dozens of robust components. In fact, it's relatively rare to find situations where you need to look beyond Vaadin's native offerings. This comprehensive library isn't surprising when you consider that Vaadin has been evolving for over 20 years - making it old enough to be the "father" of Angular and React (or at least their uncle). Throughout these two decades, the Vaadin team has continuously perfected and expanded their component library. Understanding the Concept of Fields Understanding the Concept of Fields Up until now, we've extensively discussed fields in Vaadin. However, it's crucial to clarify that we've primarily been referring to "Input Fields." Whenever we mention "fields," we're typically talking about components that hold values and properties. But let's broaden our perspective. In the Vaadin ecosystem, the term "fields" doesn't necessarily always refer to input fields. The concept extends to various UI components, which opens up fascinating possibilities for interface development. The Creative Drive of Necessity The Creative Drive of Necessity Human beings possess a curious tendency to innovate beyond what's already sufficient. This creative impulse is one of our most wonderful attributes. The same principle applies to Vaadin development - sometimes we need to venture beyond the established boundaries and incorporate external components. This is where concepts like "custom components" and "web components" become relevant. Custom components follow a straightforward concept: they're compound elements that combine either exclusively Vaadin components, or integrate Web Components with Vaadin components, or consist entirely of Web Components working together.
