How can I disable cache in puppeteer?

I want to disable cache in puppeteer, can anyone please tell me how I can do so? I found this page.setCacheEnabled(enabled) but I couldn't understand how to use the same.

I am aware that the browser is launched without cache or cookies but in my case the browser is always running in the background thus need a different solution.

You can use cdpSession.send() to disable cache:

const client = await page.target().createCDPSession();

await client.send('Network.setCacheDisabled', {
  cacheDisabled: true,
});

Alternatively, you can use the more readable page.setCacheEnabled():

await page.setCacheEnabled(false);

If you want session isolation, there is also: const context = await browser.createIncognitoBrowserContext(); const page = await context.newPage(); which will give you a fresh start on each page.

According to the puppeteer docs you can use await page.setCacheEnabled(enabled)

This was added back in December. See Git Hub issue #1609

If you look at the commit changes there is a test e.g.

await page.goto(SOMEURL);

await page.reload({waitUntil: 'networkidle2'});
expect(responses.get('one-style.css').fromCache()).toBe(true);

await page.setCacheEnabled(false);
await page.reload({waitUntil: 'networkidle2'});
expect(responses.get('one-style.css').fromCache()).toBe(false);

Every browser launch starts with clean HTTP cache and without any cookies.

let browser = await puppeteer.launch(); // no cache, no cookies!

You may try this. For my cases without cache , i am using this.
