Playwright Java how to save a web page to a pdf?

There are two ways to do it.

From command line

To do it in command line open the terminal from project and type below command.

mvn exec:java -e -D exec.mainClass=com.microsoft.playwright.CLI -D exec.args="pdf blazedemo.com/login mylogin.pdf"

This will create a PDF of the blazedemo.com/login page and save it to a file called mylogin.pdf.

The command uses the following options:

mvn exec:java — This executes the Java code in the current project.
-e — This enables the error output.
-D exec.mainClass=com.microsoft.playwright.CLI — This specifies the main class of the Java code to execute.
-D exec.args=”pdf blazedemo.com/login mylogin.pdf” — This specifies the arguments to pass to the Java code.
The pdf argument tells the Playwright CLI to create a PDF of the current page. The blazedemo.com/login argument specifies the URL of the page to create a PDF of. The mylogin.pdf argument specifies the name of the file to save the PDF to.

Here is a breakdown of the command:

mvn — This is the Maven command-line tool.
exec:java — This Maven plugin executes Java code.
-e — This enables the error output.
-D exec.mainClass=com.microsoft.playwright.CLI — This specifies the main class of the Java code to execute.
-D exec.args=”pdf blazedemo.com/login mylogin.pdf” — This specifies the arguments to to pass to the Java code.

The second way is using Java code.

package com.sam.scripts;

import com.microsoft.playwright.*;
import com.pages.BlazeDemoPage;
import org.testng.annotations.Test;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class BrowserTypes {

    @Test
    public void firstTest() throws InterruptedException, IOException {

        String workingDirectory = System.getProperty("user.dir");
        Path pdfsFolder = Paths.get(workingDirectory, "pdfFolder");

        // Create the folder if it doesn't exist
        if (!Files.exists(pdfsFolder)) {
            Files.createDirectory(pdfsFolder);
        }
        Path pdfPath = pdfsFolder.resolve("myLoginPage.pdf");
        Playwright playwright = Playwright.create();
        // this only works for chromium() and also it should be headless as well.
        Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(true));
        Page page = browser.newPage();
        page.navigate("https://blazedemo.com/login");
        page.pdf(new Page.PdfOptions().setPath(Paths.get(pdfPath.toString())));
        Locator username = page.locator(BlazeDemoPage.TXT_USERNAME);
}
}

Note that this code only works in Chromium and also headless mode should be true.
