Sorry if this has already been asked and answered (documentation is somewhat sparse and scattered for kotlin-react). How do I import into Kotlin and use a *JavaScript* react library (for example <https://react-bootstrap.github.io/>)?

<https://kotlinlang.org/docs/reference/js-interop.html>

Here you can see how the library `react-router-dom` has been declared:
<https://github.com/JetBrains/kotlinconf-app/blob/master/web/src/main/kotlin/org/jetbrains/kotlinconf/components/routing.kt>
and how it has been wrapped:
<https://github.com/JetBrains/kotlinconf-app/blob/master/web/src/main/kotlin/org/jetbrains/kotlinconf/components/routingDsl.kt>

```
external class HashRouterComponent : React.Component&lt;RProps, RState&gt; {
    override fun render(): ReactElement?
}
```

It doesn't look like a correct declaration of external component though it may work in this particular case

Correct would be this:
```
external val HashRouterComponent: RClass&lt;RProps&gt;
```

Example can be found here: <https://github.com/JetBrains/kotlin-wrappers/blob/master/examples/src/main/kotlin/example/Quill.kt>

You can also use this converter to take any javascript library that has typescript bindings and wrap it in kotlin
