Java Playwright + Browserless ignore browser download

Question

I am developing a simple prototype with Java + Playwright + Browserless. I was wondering if is possible avoid downloading the browsers in AWS.

Playwright build of chromium v956323 downloaded to /home/ec2-user/.cache/ms-playwright/chromium-956323
Playwright build of ffmpeg v1007 downloaded to /home/ec2-user/.cache/ms-playwright/ffmpeg-1007
Playwright build of firefox v1313 downloaded to /home/ec2-user/.cache/ms-playwright/firefox-1313
Playwright build of webkit v1596 downloaded to /home/ec2-user/.cache/ms-playwright/webkit-1596

Sometimes it will run in browserless and i think if so i wont need the browser but i dont really know is this possible? or even running in browserless i would need the browsers?

If so how can i do that in Java.

I want to do it programmatically because depending of the parameters sometime i need them sometimes dont is this possible?

What do you mean by "browserless"? In case you mean "headless": Yes, you also need to download the browsers when running in headless mode. — Christian Baumann, Mar 15 '22 at 15:28
Delegating the call to a external provider Browserless is one of them. — chiperortiz, Mar 15 '22 at 19:17

You can skip the browser download by setting an environment variable PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD=1

See the docs here: https://playwright.dev/java/docs/browsers#skip-browser-downloads

But i want to do it programmatically i mean depending of the configuration sometimes it will run in the browsers in the same machine and sometimes in different providers. – chiperortiz Mar 15 '22 at 19:15

Sorry, missed that bit. How to set an env var programmatically in Java depends on your OS, lots of possibilities covered here: https://stackoverflow.com/questions/318239/how-do-i-set-environment-variables-from-java – Christian Baumann Mar 15 '22 at 19:36

Map<String,String> env = new HashMap<>();
env.put("PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD","1");
try (Playwright playwright = Playwright.create(new Playwright.CreateOptions().setEnv(env))) {
        BrowserType chromium = playwright.chromium();
        Browser browser = chromium.launch();
        Page page = browser.newPage();
        page.onRequest(request -> System.out.println(">> " + request.method() + " " + request.url()));
        page.onResponse(response -> System.out.println("<<" + response.status() + " " + response.url()));
        page.navigate("https://example.com");
        browser.close();
    }
}
