I'm the Scrapman!

Scrapman is a blazingly fast real (with Javascript executed) HTML scrapper, built from the ground up to support parallel fetches, with this you can get the HTML code for 50+ URLs in seconds (~30 seconds).

On NodeJS you can easily use request to fetch the HTML from a page, but what if the page you are trying to load is NOT a static HTML page, but it has dynamic content added with Javascript? What do you do then? Well, you use The Scrapman.

It uses Electron to dynamically load web pages into several <webview> within a single Chromium instance. This is why it fetches the HTML exactly as you would see it if you inspect the page with DevTools.

This is NOT an browser automation tool (yet), it's a node module that gives you the processed HTML from an URL, it focuses on multiple parallel operations and speed.

1.- Install it

npm install scrapman -S

2.- Require it

var scrapman = require("scrapman");

3.- Use it (as many times as you need)

Single URL request

scrapman.load("http://google.com", function(results){
	//results contains the HTML obtained from the url
	console.log(results);
});

Parallel URL requests

//yes, you can use it within a loop.
for(var i=1; i<=50; i++){
    scrapman.load("https://www.website.com/page/" + i, function(results){
        console.log(results);
    });
}

Type: String

The URL from which the HTML code is going to be obtained.

Type: Function

The callback function to be executed when the loading is done. The loaded HTML will be in the results parameter.

The configuration object can set the following values

• maxConcurrentOperations: Integer - The intensity of processing, how many URLs can be loaded at the same time, default: 50

• wait: Integer - The amount of milliseconds to wait before returning the HTML code of a webpage after it has been completely loaded, default: 0

Feel free to open Issues to ask questions about using this package, PRs are very welcomed and encouraged.
