Examples
You can find Maven project with the examples here.
Page screenshot
This code snippet navigates to whatsmyuseragent.org in Chromium, Firefox and WebKit, and saves 3 screenshots.
import com.microsoft.playwright.*;
import java.nio.file.Paths;
import java.util.Arrays;
import java.util.List;
public class PageScreenshot {
public static void main(String[] args) throws Exception {
Playwright playwright = Playwright.create();
List<BrowserType> browserTypes = Arrays.asList(
playwright.chromium(),
playwright.webkit(),
playwright.firefox()
);
for (BrowserType browserType : browserTypes) {
Browser browser = browserType.launch();
BrowserContext context = browser.newContext(
new Browser.NewContextOptions().withViewport(800, 600));
Page page = context.newPage();
page.navigate("http://whatsmyuseragent.org/");
page.screenshot(new Page.ScreenshotOptions().withPath(Paths.get("screenshot-" + browserType.name() + ".png")));
browser.close();
}
playwright.close();
}
}
Mobile and geolocation
This snippet emulates Mobile Chromium on a device at a given geolocation, navigates to openstreetmap.org, performs action and takes a screenshot.
import com.microsoft.playwright.*;
import java.nio.file.Paths;
import static java.util.Arrays.asList;
public class MobileAndGeolocation {
public static void main(String[] args) throws Exception {
Playwright playwright = Playwright.create();
BrowserType browserType = playwright.chromium();
Browser browser = browserType.launch(new BrowserType.LaunchOptions().withHeadless(false));
DeviceDescriptor pixel2 = playwright.devices().get("Pixel 2");
BrowserContext context = browser.newContext(new Browser.NewContextOptions()
.withDevice(pixel2)
.withLocale("en-US")
.withGeolocation(new Geolocation(41.889938, 12.492507))
.withPermissions(asList("geolocation")));
Page page = context.newPage();
page.navigate("https://www.openstreetmap.org/");
page.click("a[data-original-title=\"Show My Location\"]");
page.screenshot(new Page.ScreenshotOptions().withPath(Paths.get("colosseum-pixel2.png")));
browser.close();
playwright.close();
}
}
Evaluate in browser context
This code snippet navigates to example.com in Firefox, and executes a script in the page context.
import com.microsoft.playwright.*;
public class EvaluateInBrowserContext {
public static void main(String[] args) throws Exception {
Playwright playwright = Playwright.create();
BrowserType browserType = playwright.firefox();
Browser browser = browserType.launch(new BrowserType.LaunchOptions().withHeadless(false));
BrowserContext context = browser.newContext();
Page page = context.newPage();
page.navigate("https://www.example.com/");
Object dimensions = page.evaluate("() => {\n" +
" return {\n" +
" width: document.documentElement.clientWidth,\n" +
" height: document.documentElement.clientHeight,\n" +
" deviceScaleFactor: window.devicePixelRatio\n" +
" }\n" +
"}");
System.out.println(dimensions);
browser.close();
playwright.close();
}
}
Intercept network requests
This code snippet sets up request routing for a WebKit page to log all network requests.
import com.microsoft.playwright.*;
public class InterceptNetworkRequests {
public static void main(String[] args) throws Exception {
Playwright playwright = Playwright.create();
BrowserType browserType = playwright.webkit();
Browser browser = browserType.launch();
BrowserContext context = browser.newContext();
Page page = context.newPage();
page.route("**", route -> {
System.out.println(route.request().url());
route.continue_();
});
page.navigate("http://todomvc.com");
browser.close();
playwright.close();
}
}
Documentation
We are in the process of converting our documentation from the Node.js form to Javadocs. You can go ahead and use the Node.js documentation since the API is pretty much the same.

Is Playwright for Java ready?
Yes, Playwright for Java is ready. We are still not at the version v1.0, so breaking API changes could potentially happen. But a) this is unlikely and b) we will only do that if we know it improves your experience with the new library. We'd like to collect your feedback before we freeze the API for v1.0.
Note: We don't yet support some of the edge-cases of the vendor-specific APIs such as collecting Chromium trace, coverage report, etc.
