# Modules

KVision consists of both required and optional functionality. Modules can be added as dependencies in `build.gradle.kts` file. 

All modules which include CSS stylesheets require explicit initialization. This also applies to the core module. This initialization ensures a predictable order in which all styles will be applied. The initialization is performed by adding dedicated module objects as parameters to the `startApplication()` function.

```kotlin
fun main() {
    startApplication(
        ::App,
        module.hot,
        BootstrapModule,
        BootstrapCssModule,
        FontAwesomeModule,
        TomSelectModule,
        DatetimeModule,
        BootstrapUploadModule,
        CoreModule
    )
}
```

{% hint style="info" %}
Some modules include more than one, optional initializers. E.g. `kvision-tabulator` module includes mandatory `TabulatorModule` but also `TabulatorCssBootstrapModule` , `TabulatorCssBulmaModule`, `TabulatorCssMaterializeModule`, `TabulatorCssMidnightModule`, `TabulatorCssModernModule`, `TabulatorCssSemanticModule`, `TabulatorCssSimpleModule` and `TabulatorCssStandardModule` for all CSS styles supported by the Tabulator component.
