chrome-reactive-kotlin v0.7.1
chrome-reactive-kotlin is a low level Chrome DevTools Protocol client written in Kotlin and leveraging RxJava3 for easy composability.
Library exposes all protocol domains in a single, cohesive and highly composable API. It supports both headless and standalone Chrome versions and supports creating isolated environments via BrowserContext from Target domain and flatted sessions mode (see: http://crbug.com/991325).
For debugging purposes you can use my other project: chrome-protocol-proxy.
Please note that most up-to-date protocol is used at the moment.
Documentation can be found on https://wendigo.github.io/chrome-reactive-kotlin/.

And now execute:
import pl.wendigo.chrome.api.page.NavigateRequest
fun main() {
val chrome = Browser.builder()
.withAddress("127.0.0.1:9222")
.build()
chrome.use { browser ->
browser.target("about:blank").use { target ->
await {
target.Page.enable()
}
await {
target.Page.navigate(NavigateRequest(url = "https://github.com/wendigo/chrome-reactive-kotlin")).flatMap { (frameId) ->
target.Page.frameStoppedLoading().filter {
it.frameId == frameId
}.take(1).singleOrError()
}
}
}
