In Vaadin 10+, all components are basically add-ons. Previously we shipped the core component set in one module, but now all component implementations are different modules. Most often in your build file, you only use Vaadin BOM, which defines a set of modules that are tested to work together, and quite often vaadin-core, which aggregates the most commonly used UI components to your classpath at once.
