Search Engine Scraper

This node module supports scraping several search engines.

Right now scraping the search engines

Google
Google News
Google News New (https://news.google.com)
Google Image
Bing
Baidu
Youtube
Infospace
Duckduckgo
Webcrawler

is supported.

Additionally se-scraper supports investment ticker search from the following sites:

Bloomberg
Reuters
cnbc
Marketwatch

This module uses puppeteer. It was created by the Developer of https://github.com/NikolaiT/GoogleScraper, a module with 1800 Stars on Github.

Technical Notes

Scraping is done with a headless chromium browser using the automation library puppeteer. Puppeteer is a Node library which provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol.

No multithreading is supported for now. Only one scraping worker per scrape() call.

If you need to deploy scraping to the cloud (AWS or Azure), you can contact me on hire@incolumitas.com

Installation and Usage

Install with

npm install se-scraper

Use se-scraper by calling it with a script such as the one below.

const se_scraper = require('se-scraper');
const resolve = require('path').resolve;

let config = {
    // the user agent to scrape with
    user_agent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36',
    // if random_user_agent is set to True, a random user agent is chosen
    random_user_agent: false,
    // get meta data of scraping in return object
    write_meta_data: false,
    // how long to sleep between requests. a random sleep interval within the range [a,b]
    // is drawn before every request. empty string for no sleeping.
    sleep_range: '',
    // which search engine to scrape
    search_engine: 'google',
    // whether debug information should be printed
    // debug info is useful for developers when debugging
    debug: false,
    // whether verbose program output should be printed
    // this output is informational
    verbose: false,
    // an array of keywords to scrape
    keywords: ['scrapeulous.com', ],
    // alternatively you can specify a keyword_file. this overwrites the keywords array
    keyword_file: '',
    // whether to start the browser in headless mode
    headless: true,
    // path to output file, data will be stored in JSON
    output_file: 'data.json',
    // whether to prevent images, css, fonts from being loaded
    // will speed up scraping a great deal
    block_assets: true,
    // path to js module that extends functionality
    // this module should export the functions:
    // get_browser, handle_metadata, close_browser
    // must be an absolute path to the module
    //custom_func: resolve('examples/pluggable.js'),
    custom_func: '',
};

se_scraper.scrape(config, (err, response) => {
    if (err) { console.error(err) }

    /* response object has the following properties:

        response.results - json object with the scraping results
        response.metadata - json object with metadata information
        response.statusCode - status code of the scraping process
     */

    console.dir(response.results, {depth: null, colors: true});
});

Supported options for the search_engine config key:

'google'
'google_news_old'
'google_news'
'google_image'
'bing'
'bing_news'
'infospace'
'webcrawler'
'baidu'
'youtube'
'duckduckgo_news'
'google_dr'
'yahoo_news'
// ticker search
'bloomberg'
'reuters'
'cnbc'
'marketwatch'

Output for the above script on my laptop:

Scraper took 4295ms to scrape 2 keywords.
On average ms/keyword: 2147.5ms/keyword
