Apify SDK is a preferred tool when other solutions fall flat during heavier tasks – performing deep crawls, rotating proxies to mask the browser, scheduling the scraper to run multiple times, caching results to prevent data prevention if the code happens to crash, and more. Foxin drivers. Apify handles such operations with ease but it can also help to develop web scrapers of your own in Javascript.

Node SimpleCrawler

Simplecrawler is designed to provide a basic, flexible, and robust API for crawling websites. It was written to archive, analyze, and search some very large websites and can get through hundreds of thousands of pages and write large volumes of data without issue. It has a lot of useful events that can help you track the progress of your crawling process. This crawler is extremely configurable and there’s a long list of settings you can change to adapt it to your specific needs.

NodeCrawler

Nodecrawler is a popular web crawler for NodeJS, making it a very fast crawling solution. If you prefer coding in JavaScript, or you are dealing with mostly a Javascript project, Nodecrawler will be the most suitable web crawler to use. Its installation is pretty simple too. JSDOM and Cheerio (used for HTML parsing) use it for server-side rendering, with JSDOM being more robust.

Requires Version – Node v4.0.0 or greater

PJscrape is a web scraping framework written in Python using Javascript and JQuery. It is built to run with PhantomJS, so it allows you to scrape pages in a fully rendered, Javascript-enabled context from the command line, with no browser required. The scraper functions are evaluated in a full browser context. This means you not only have access to the DOM, but you also have access to Javascript variables and functions, AJAX-loaded content, etc.

Requires Version – Node v4.0.0+, PhantomJS v.1.3+
Available Selectors – CSS
Available Data Format – JSON

Puppeteer

Puppeteer is a Node library which provides a powerful but simple API that allows you to control Google’s headless Chrome browser. A headless browser means you have a browser that can send and receive requests but has no GUI. It works in the background, performing actions as instructed by an API. You can truly simulate the user experience, typing where they type and clicking where they click.

A headless browser is a great tool for automated testing and server environments where you don’t need a visible UI shell. For example, you may want to run some tests against a real web page, create a PDF of it, or just inspect how the browser renders a URL. Puppeteer can also be used to take screenshots of web pages visible by default when you open a web browser.

Puppeteer’s API is very similar to Selenium WebDriver, but works only with Google Chrome. Puppeteer has a more active support than Selenium, so if you are working with Chrome, Puppeteer is your best option for web scraping.

Requires Version – Node v6.4.0, Node v7.6.0 or greater
Available Selectors – CSS
Available Data Formats – JSON

Pros

• With its full-featured API, it covers a majority of use cases
• The best option for scraping Javascript websites on Chrome

Cons

• Only available for Chrome/Chromium browser

Best Use Case

• If you need to test the speed, performance, responsivenes, and UI of a website.
• If you are using Chrome, Puppeteer is your best option for web scraping.
• If the information you want is generated using

Playwright

Playwright is a Node library to automate multiple browsers with a single API. It enables cross-browser web automation that is ever-green, capable, reliable, and fast. Playwright was created to improve automated UI testing by eliminating flakiness, improving the speed of execution, and offering insights into the browser operation.

Playwright is very similar to Puppeteer in many respects. The API methods are identical in most cases, and Playwright also bundles compatible browsers by default. Playwright’s biggest differentiating point is cross-browser support. It can drive Chromium, WebKit, MS Edge, and Firefox.

A noteworthy difference is that Playwright has a more powerful browser context feature than Puppeteer. This lets you simulate multiple devices with a single browser instance.

Best Web Scraping Tool

Requires Version – Node.js 10.15 or above.
Available Selectors – CSS
Available Data Formats – JSON

Pros

Best Web Browser Best Web Scraping Tools

Best use case

If you need an efficient tool as good as Puppeteer to perform UI testing but across multiple browsers, you should use Playwright.

Cheerio

Cheerio is a library that parses raw HTML and XML documents and allows you to use the syntax of jQuery while working with the downloaded data. With Cheerio, you can write filter functions to fine-tune which data you want from your selectors. If you are writing a web scraper in JavaScript, Cheerio API is a fast option that makes parsing, manipulating, and rendering efficient.

It does not – interpret the result as a web browser, produce a visual rendering, apply CSS, load external resources, or execute JavaScript. If you require any of these features, you should consider projects like PhantomJS or JSDom.

Requirements – Up to date versions of Node.js and npm
Available Selectors – CSS

Pros

• Parsing, rendering and manipulating documents is very efficient
• Flexible, Easy to Use
• Very fast (Preliminary end to end benchmarks suggests its 8x faster than JSDOM)
