Install Apify SDK into a Node.js project. You must have Node.js 10 or higher installed.

npm install apify puppeteer

Copy the following code into a file in the project, for example main.js:

const Apify = require('apify');

Apify.main(async () => {
    const requestQueue = await Apify.openRequestQueue();
    await requestQueue.addRequest({ url: 'https://www.iana.org/' });

    const crawler = new Apify.PuppeteerCrawler({
        requestQueue,
        handlePageFunction: async ({ request, page }) => {
            const title = await page.title();
            console.log(`Title of ${request.url}: ${title}`);
            await Apify.utils.enqueueLinks({
               requestQueue,
               page,
               pseudoUrls: ['https://www.iana.org/[.*]'],
            });
        },
    });

    await crawler.run();
});

Execute the following command in the project's folder and watch it recursively crawl IANA with Puppeteer and Chromium.

node main.js
