apify-js是一款用于 JavaScript 的可伸缩的 web 爬虫和抓取库。能通过无头（headless）Chrome 和 Puppeteer 实现数据提取和 Web 自动化作业的开发。  它提供了管理和自动扩展无头Chrome / Puppeteer实例池的工具，维护要爬网的URL队列，将爬网结果存储到本地文件系统或云端。

安装：

npm install apify --save

运行以下示例以使用Puppeteer执行网站的爬取：

const Apify = require('apify');

Apify.main(async () => {
    const requestQueue = await Apify.openRequestQueue();
    await requestQueue.addRequest({ url: 'https://www.iana.org/' });
    const pseudoUrls = [new Apify.PseudoUrl('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.puppeteer.enqueueLinks(page, 'a', pseudoUrls, requestQueue);
        },
        maxRequestsPerCrawl: 100,
        maxConcurrency: 10,
    });

    await crawler.run();
});
