ember-google-publisher-tags

An Ember component for adding GPT ads to your site.

Usage

{{google-publisher-tag adId="/6355419/Travel/Europe/France/Paris" width=300 height=250}}

The adId is taken straight from DFP's "Generate Tags" link. The above is a sample ad on Google's ad network.

Optional properties:

placement=N: Differentiate ads that use the same adId on a single page. For example, one ad might be placement="upper right", while another might be placement="lower left".
refresh=N: Refresh the ad after N seconds. Each refresh also increments the refreshCount property, which might be useful.
refreshLimit=N Limit refreshing to N times. For example, setting to 5 would stop refreshing after the 5th time.
tracing=true: Turn on Ember.Logger.log tracing.
shouldWatchViewport=false: Turn off checks for ad in view, if using tons of ads slows down your page.
backgroundRefresh=true: By default, we do not refresh ads in backgrounded pages, according to the document.hidden property. If, for some strange reason, you want to refresh ads while nobody is looking, set this to true.

Additionally, if you want to use GPT's setTargeting function to serve targeted ads, extend the GooglePublisherTag component and override the addTargeting function in your child component. Inside this function, set the targeting property to an object:

// components/your-ad.js
import GPT from 'ember-google-publisher-tags/components/google-publisher-tag';

export default GPT.extend({
    tracing: true, // useful for development, especially if it's computed

    addTargeting() {
        // depending on your application, you might want to check Ember's
        // `isDestroyed` and `isDestroying` properties before calling `set`
        set(this, 'targeting', {
            placement: get(this, 'placement'),
            refresh_count: get(this, 'refreshCount'),
            planet: 'Earth'
        });
    }
};

<!-- application.hbs -->
{{your-ad adId="..." width=300 height=250}}

Installation

ember install ember-google-publisher-tags
If your app uses Ember's default index.html, no further installation is needed: this addon uses Ember's head-footer hook to insert the GPT initialization code into your page <head>s (unless you use iframeJail, see below).
If #2 does not apply to you, you'll have to manually add the GPT initialization <script> tag to your page <head>. Copy it from either index.js or gpt-iframe.html, and paste it wherever you need to in your app's structure.

Configuration

gpt.iframeJail: boolean (default: false)

By default, GPT runs in your page's window. Since ads do all sorts of malicious crap, you can have the ads run inside an <iframe> jail of their very own. This addon comes with its own gpt-iframe.html file for exactly this purpose. Set this property to true to:

Put all GPT javascript inside its own <iframe>
disable the head-footer hook for this addon, so that your page <head> is unaffected

gpt.iframeRootUrl: string (default: ENV.rootURL)

If your dist folder is not accessible at your application-defined rootURL, use this property.

// config/environment.js

module.exports = function(environment) {
    var ENV = {
        gpt: {
            // your config settings
            iframeJail: true,
            iframeRootUrl: '/somewhere/else/'
        }
    };

gpt.iframeExternalUrl: string (default: none)

Use this url to host your ad iframe on a completely separate domain. Because of cross-origin policy, using this kind of iframe requires passing things like ad ID and targeting info via url query param, instead of via .contentWindow. This also means whatever is handling the url needs to decode the query parameter and pass it along to the GPT javascript.

iframeExternalUrl will ignore iframeRootUrl, if both are defined in your environment.js.

Here is a full example:

Define iframeExternalUrl as //www.example.com/gpt-iframe.php?q=. Note that url ends with an unset query parameter: this is required.

The addon will create an iframe like this:

<iframe src="//wwww.example.com/gpt-iframe.php?q=%7B%22ad%22%3A%7B%22adId%22
%3A%22%2F6355419%2FTravel%2FEurope%2FFrance%2FParis%22%2C%22width%22%3A300
%2C%22height%22%3A250%7D%2C%22targeting%22%3A%5B%5B%22planet%22%2C%22Earth
%22%5D%2C%5B%22refreshCount%22%3A%222%22%5D%5D%7D%0A" ...></iframe>

The above query-encoded string is JSON, if it was decoded and pretty-printed it would be:

{
  "ad": {
    "adId": "/6355419/Travel/Europe/France/Paris",
    "width":300,
    "height":250
  },
  "targeting": [
    ["planet","Earth"],
    ["refreshCount":"2"]
  ]
}

The PHP that handlesgq}J the request looks very similar to gpt-iframe.html, except it decodes the query string and assigns window.ad and window.targeting. It also doesn't have to worry about polling the window.startCallingGpt variable, so that code is removed.

<?php
$params = json_decode($_GET['q']);
function json2js($k) {
    global $params;
    return json_encode($params->$k, JSON_UNESCAPED_SLASHES) . ";\n";
}
?>
<html>
    <head>
        <script type='text/javascript'>
var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
(function() {
    var gads = document.createElement('script');
    gads.async = true;
    gads.type = 'text/javascript';
    var useSSL = 'https:' == document.location.protocol;
    gads.src = (useSSL ? 'https:' : 'http:') +
      '//www.googletagservices.com/tag/js/gpt.js';
    var node = document.getElementsByTagName('script')[0];
    node.parentNode.insertBefore(gads, node);
})();
        </script>
        <style>
body {
    margin: 0;
}
        </style>
    </head>
    <body>
        <div id="gpt-ad"></div>
        <script>

window.ad = <?= json2js('ad') ?>
window.targeting = <?= json2js('targeting') ?>

var g = googletag;
g.cmd.push( function() {
    var slot = g.defineSlot(
        window.ad.adId,
        [ window.ad.width, window.ad.height ],
        "gpt-ad"
    ).addService(g.pubads());

    if (window.targeting) {
        window.targeting.forEach(function(pair) {
            slot.setTargeting(pair[0], pair[1]);
        });
    }

    g.enableServices();
    g.display("gpt-ad");
});
        </script>
    </body>
</html>

Troubleshooting

Make sure your ad blocker isn't interfering.
Set tracing to true, and follow what the addon does in your browser's console.
Add googfc as a query parameter to your url, this will activate an in-page debugging console. Eg, http://localhost:4200/?googfc. More info here.
