addHandler

inline fun <T> Connection.addHandler(coroutineScope: CoroutineScope, crossinline event: CDP.() -> Flow<T>, crossinline handler: suspend (T) -> Unit): Job

Adds a handler for a specific CDP event.

This is an alias so that you can use cdp the same way as zendriver does:

// add a handler for the consoleAPICalled event with kdriver
tab.addHandler(this, { cdp.runtime.consoleAPICalled }) { event ->
    println(event)
}

That would be equivalent to this with zendriver:

# add a handler for the consoleAPICalled event with zendriver
tab.add_handler(cdp.runtime.ConsoleAPICalled, lambda event: print(event))

Although you can directly collect the events from the tab (recommended way of doing it):

// add a handler for the consoleAPICalled event with kdriver, directly
launch {
    tab.runtime.consoleAPICalled.collect { event ->
        println(event)
    }
}

Return

A Job that can be used to cancel the handler.

Parameters

coroutineScope

The coroutine scope in which the handler will run.

event

A lambda that returns a Flow of the event type to listen to.

handler

A suspend function that will be called with each event of the specified type.
