Nullean.Cdp
A small Chrome DevTools Protocol client for .NET: find and launch Chrome, drive pages with agent-browser style locators, and read the accessibility tree. Native AOT and trim clean, with no dependencies beyond the BCL.
Install
dotnet add package Nullean.Cdp
Quick start
using Nullean.Cdp;
using Nullean.Cdp.Accessibility;
await using var browser = await Browser.LaunchAsync(); // headless, temporary profile
await using var context = await browser.NewContextAsync(); // own cookies and storage
var page = await context.NewPageAsync();
await page.GotoAsync("http://localhost:5000/");
Console.Write(await page.SnapshotAsync(new AxSnapshotOptions { Compact = true, Selector = "main" }));
// - main
// - heading "Fixture shop" [level=1]
// - textbox "Search"
// - checkbox "Only in stock" [checked=true]
Locators wait for their element and act like a user:
await page.Label("Search").FillAsync("lamp");
await page.Role("checkbox", "Only in stock").CheckAsync();
await page.Role("button", "Go").ClickAsync(); // waits for any navigation it starts
await page.Text("3 results").WaitAsync();
page.SendAsync(method, params) and browser.Connection reach any CDP command the library does not wrap.
Finding Chrome
CDP_CHROME, then CHROME_PATH, then the standard install locations for Chrome, Chrome for Testing, Chromium and
Edge on each OS, then google-chrome, chromium and chrome on the PATH. When nothing is found, the error lists
every place it looked.
