Capture a screenshot using Puppeteer

Using Puppeteer directly

tip

To run this example on the Apify Platform, select the apify/actor-node-puppeteer-chrome image for your Dockerfile.

This example captures a screenshot of a web page using Puppeteer. It would look almost exactly the same with Playwright.

Page Screenshot

Using page.screenshot():

Run on

import { KeyValueStore, launchPuppeteer } from 'crawlee';

const keyValueStore = await KeyValueStore.open();

const url = 'https://crawlee.dev';
// Start a browser
const browser = await launchPuppeteer();

// Open new tab in the browser
const page = await browser.newPage();

// Navigate to the URL
await page.goto(url);

// Capture the screenshot
const screenshot = await page.screenshot();

// Save the screenshot to the default key-value store
await keyValueStore.setValue('my-key', screenshot, { contentType: 'image/png' });

// Close Puppeteer
await browser.close();

Crawler Utils Screenshot

Using utils.puppeteer.saveSnapshot():

Run on

import { launchPuppeteer, utils } from 'crawlee';

const url = 'http://www.example.com/';
// Start a browser
const browser = await launchPuppeteer();

// Open new tab in the browser
const page = await browser.newPage();

// Navigate to the URL
await page.goto(url);

// Capture the screenshot
await utils.puppeteer.saveSnapshot(page, { key: 'my-key', saveHtml: false });

// Close Puppeteer
await browser.close();

Using PuppeteerCrawler

This example captures a screenshot of multiple web pages when using PuppeteerCrawler:

Page Screenshot

Using page.screenshot():

Run on

import { PuppeteerCrawler, KeyValueStore } from 'crawlee';

// Create a PuppeteerCrawler
const crawler = new PuppeteerCrawler({
    async requestHandler({ request, page }) {
        // Capture the screenshot with Puppeteer
        const screenshot = await page.screenshot();
        // Convert the URL into a valid key
        const key = request.url.replace(/[:/]/g, '_');
        // Save the screenshot to the default key-value store
        await KeyValueStore.setValue(key, screenshot, { contentType: 'image/png' });
    },
});

await crawler.addRequests([
    { url: 'http://www.example.com/page-1' },
    { url: 'http://www.example.com/page-2' },
    { url: 'http://www.example.com/page-3' },
]);

// Run the crawler
await crawler.run();

Crawler Utils Screenshot

Using the context-aware saveSnapshot() utility:

Run on

import { PuppeteerCrawler } from 'crawlee';

// Create a PuppeteerCrawler
const crawler = new PuppeteerCrawler({
    async requestHandler({ request, saveSnapshot }) {
        // Convert the URL into a valid key
        const key = request.url.replace(/[:/]/g, '_');
        // Capture the screenshot
        await saveSnapshot({ key, saveHtml: false });
    },
});

await crawler.addRequests([
    { url: 'http://www.example.com/page-1' },
    { url: 'http://www.example.com/page-2' },
    { url: 'http://www.example.com/page-3' },
]);

// Run the crawler
await crawler.run();

In both examples using page.screenshot(), a key variable is created based on the URL of the web page. This variable is used as the key when saving each screenshot into a key-value store.
