How to integrate a JavaScript library in Vaadin 14+

Vaadin gives you the possibility to create a web application only with Java. That’s great but sometimes you need to extend the design system with new components. You have different solutions to extend or create a new component, from the simplest to the hardest:

• You can use different Java components. You don’t need to use any JavaScript, it’s easy to maintain and the official documentation is quite good.
• You can use an existing web component. The official documentation is also great. But there is nothing that help you to choose the right library.
• You can use a Javascript library and use it.
• You can build your own component.
