ChromeDevTools

.Net library to interact with Chrome using the Chrome DevTools Protocol

When Chrome is started with --remote-debugging-port=9222, it can be controlled programatically via REST API and WebSocket using Chrome DevTools Protocol. This library provides .Net friendly API to work with the protocol.

Getting Started

PM> Install-Package DumbPrograms.ChromeDevTools

If you already have Chrome running with --remote-debugging-port=9222, you can simply start with

var devTools = new DevToolsClient(9222);

This library includes ChromeProcessHelper to help you start Chrome with relavent commandline args

using (var chrome = ChromeProcessHelper.StartNew())
{
    var devTools = chrome.GetDevTools();
}

Once you have DevToolsClient, you can explore inspectable targets

var targets = from t in await devTools.GetInspectableTargets()
              where t.Type == "page"
              select t;

Then you can pick up a target and inspect

var t0 = targets.First();

using (var inspector = await devTools.Inspect(t0))
{
    await inspector.Page.Enable();

    await inspector.Page.Navigate("https://github.com");

    var e = await inspector.Page.LoadEventFiredEvent();

    Console.WriteLine($"Page loaded at {e.Timestamp.Value}");
}

Please keep in mind that these APIs are almost always async, putting Async suffices to the method names are unnecessary. Just remember to await the API calls unless you don't want.

Building

Refreshing

1. Make sure the Generator project is built.
2. Build the DevTools project with either -property:RefreshProtocolJsonFiles=true or your json files placed in the Generated folder.
