Getting Started

Dependencies

Install the following prerequisite on your development machine:

• Node.js - version >= 6.0.0

Notable npm Modules

• PDFKit
• PhantomJS
• Simple Web Crawler

Quick Start

$ npm install siteshooter --global

If siteshooter is installed, make sure you have the latest version by running:

$ npm update siteshooter --global

• You may need to run these commands with elevated privileges, e.g. sudo, you will be prompted to do so if needed.
• Installing with the --global flag affords you the siteshooter command on your machine's command line at any path.
• Read more about the --global flag here.

Create a Siteshooter Configuration File

$ siteshooter --init

Update Siteshooter Configuration File

View the full siteshooter.yml example

Inside siteshooter.yml, add additional options.

• All Simple Web Crawler options can be added to sitecrawler_options and will pass through to the crawler process
• Generated screenshot image files are optimized using imagemin and imagemin-pngquant modules, which reduce the overall size of generated PDFs. To adjust the image quality, update the image_quality option in your siteshooter.yml file.

domain:
  name: https://www.devopsgroup.io

OPTIONS
_______________________________________________________________________________________
-c --config            Show configuration
-C --cwd               Set working directory, which will load a siteshooter.yml file in the specified path
-e --debug             Output exceptions
-h --help              Print this help
-i --init              Create siteshooter.yml template file in working directory

When running a siteshooter command without any options, the following options will run in order by default:

• --sitemap
• --screenshots
• --pdf

Custom JavaScript Inject File

To manipulate the DOM, prior to the screen shot process, add a inject.js file in the same working directory as the siteshooter.yml.

Example: inject.js file

/**
 * @file:            inject.js
 * @description:     used to inject custom JavaScript into a web page prior to a screen shot. 
 */

console.log('JavaScript injected into page.');

if ( typeof(jQuery) !== "undefined" ) {

    jQuery(document).ready(function() {
        console.log('jQuery loaded.');
    });
}

Trigger JavaScript Events

When using the optional inject.js file, events can be triggered based on the following querystring parameter - pevent

 // Add URL with pevent querystring parameter in the generated sitemap.xml
<url>
    <loc>https://www.devopsgroup.io?pevent=open-privacy-overlay</loc>
    <changefreq>weekly</changefreq>
</url>

Example: Event detection & triggering

/**
 * @file:            inject.js
 * @description:     used to inject custom JavaScript into a web page prior to a screen shot. 
 */


function getQueryVariable(variable) {
    var query = window.location.search.substring(1);
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        if (decodeURIComponent(pair[0]) == variable) {
            return decodeURIComponent(pair[1]);
        }
    }
}

if ( typeof(jQuery) !== "undefined" ) {

    jQuery(document).ready(function() {
        var pageName = window.location.pathname.replace('/', ''),
            pageEvent = getQueryVariable('pevent');

        console.log('document ready.');
        console.log('userAgent', navigator.userAgent);
        console.log('Page: ', pageName);
        console.log('Event: ', pageEvent);

        switch (pageName) {

            // home
            case '':

                switch (pageEvent) {
                    case 'open-privacy-overlay':

                        jQuery('a[data-target~="#modal-privacy"]').trigger('click');
                        break;
                }

                break;
        }

    });
}

Tests

Tests are written with Mocha and can be run with npm test.

Troubleshooting

If you're having issues with Siteshooter, submit a GitHub Issue.

• Make sure you have a siteshooter.yml file in your working directory and the yaml file is well formatted
• Experiencing font-loading issues? Try increasing the delay setting in your siteshooter.yml file

screenshot_options:
  delay: 2000

• Trying to take a screenshot of a page with a video? Unfortunately, PhantomJS does not support videos. As such, here's one approach to showing a video's poster image.

/**
 * @file:            inject.js
 * @description:     used to display a video's poster image
 */

if( jQuery('video').length >0 ){
    jQuery('video').parent().prepend('<img src="'+jQuery('video').attr('poster')+'"/>');
    jQuery('video').remove();
}

• SimpleCrawler TypeError: The header content contains invalid characters
  • Try setting the acceptCookies option to false

sitecrawler_options:
  acceptCookies: false
