Crawl all links on a website

This example uses the Apify.enqueueLinks() method to add new links to the RequestQueue as the crawler navigates from page to page. If only the required parameters are defined, all links will be crawled.

Using CheerioCrawler:

const Apify = require('apify');

Apify.main(async () => {
    // Create a RequestQueue
    const requestQueue = await Apify.openRequestQueue();
    // Define the starting URL
    await requestQueue.addRequest({ url: 'https://apify.com/' });
    // Function called for each URL
    const handlePageFunction = async ({ request, $ }) => {
        console.log(request.url);
        // Add all links from page to RequestQueue
        await Apify.utils.enqueueLinks({
            $,
            requestQueue,
            baseUrl: request.loadedUrl,
        });
    };
    // Create a CheerioCrawler
    const crawler = new Apify.CheerioCrawler({
        requestQueue,
        handlePageFunction,
        maxRequestsPerCrawl: 10, // Limitation for only 10 requests (do not use if you want to crawl all links)
    });
    // Run the crawler
    await crawler.run();
});

Using PuppeteerCrawler:

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

const Apify = require('apify');

Apify.main(async () => {
    // Create a RequestQueue
    const requestQueue = await Apify.openRequestQueue();
    // Define the starting URL
    await requestQueue.addRequest({ url: 'https://apify.com/' });
    // Function called for each URL
    const handlePageFunction = async ({ request, page }) => {
        console.log(request.url);
        // Add all links from page to RequestQueue
        await Apify.utils.enqueueLinks({
            page,
            requestQueue,
        });
    };
    // Create a PuppeteerCrawler
    const crawler = new Apify.PuppeteerCrawler({
        requestQueue,
        handlePageFunction,
        maxRequestsPerCrawl: 10, // Limitation for only 10 requests (do not use if you want to crawl all links)
    });
    // Run the crawler
    await crawler.run();
});

Using PlaywrightCrawler:

const Apify = require('apify');

Apify.main(async () => {
    // Create a RequestQueue
    const requestQueue = await Apify.openRequestQueue();
    // Define the starting URL
    await requestQueue.addRequest({ url: 'https://apify.com/' });
    // Function called for each URL
    const handlePageFunction = async ({ request, page }) => {
        console.log(request.url);
        // Add all links from page to RequestQueue
        await Apify.utils.enqueueLinks({
            page,
            requestQueue,
        });
    };
    // Create a PuppeteerCrawler
    const crawler = new Apify.PlaywrightCrawler({
        requestQueue,
        handlePageFunction,
        maxRequestsPerCrawl: 10, // Limitation for only 10 requests (do not use if you want to crawl all links)
    });
    // Run the crawler
    await crawler.run();
});
