images-scraper

This a simple way to scrape Google/Bing images using Nightmare and not be dependent on any API. The headless browser will just behave like a normal person, scroll and click. A rate limiter is implemented and can be used to prevent bans. Only the Google scraper uses a headless browser, the other providers use custom requests to generate the results.

Installation

npm install images-scraper

Example Google

Give me the first 10 images of Banana's from Google (using headless browser)

var Scraper = require ('images-scraper')
  , google = new Scraper.Google();

google.list({
	keyword: 'banana',
	num: 10,
	detail: true,
	nightmare: {
		show: true
	}
})
.then(function (res) {
	console.log('first 10 results from google', res);
}).catch(function(err) {
	console.log('err', err);
});

// you can also watch on events
google.on('result', function (item) {
	console.log('out', item);
});

Example Bing (very fast)

var Scraper = require ('images-scraper')
  , bing = new Scraper.Bing();

bing.list({
	keyword: 'banana',
	num: 10,
	detail: true
})
.then(function (res) {
	console.log('first 10 results from bing', res);
}).catch(function(err) {
	console.log('err',err);
})

Yahoo

yahoo.list({
	keyword: 'banana',
	num: 10,
}).then(function (res) {
	console.log('results', res);
}).catch(function (err) {
	console.log('err',err);
});

Picsearch

pics.list({
	keyword: 'banana',
	num: 10,
}).then(function (res) {
	console.log('out',res);
}).catch(function (err) {
	console.log('err',err);
});

Options

Options that can be passed to each scraper:

var options = {
	// general
	keyword: 'keyword',		// required,
	userAgent: 'G.I. Joe',	// the user agent for each request to Google (default: Chrome)
	num: 10,				// amount of results, can be left empty but will take a lot longer

	// google specific
	rlimit: '10',			// number of requests to Google p second, default: unlimited
	timeout: 10000,			// timeout when things go wrong, default: 10000
	nightmare: {
							// all the options for Nightmare, (show: true for example)
	}	
}
