Migrating to AppMeasurement for JavaScript

If your implementation still uses H Code, Adobe highly recommends migrating to the latest version of AppMeasurement. Implementing Analytics through Adobe Experience Platform Launch is recommended, however an updated JavaScript implementation can be used.

The following notable changes are present in AppMeasurement when compared to H Code:

  • 3-7x faster than H Code.
  • Lighter than H Code - 21kb uncompressed vs. H Code, which is is 33kb uncompressed.
  • The library and page code can be deployed inside the <head> tag.
  • Existing page-level H Code is compatible with AppMeasurement.
  • The library provides native utilities to get query parameters, read and write cookies, and perform advanced link tracking.
  • The library does not support dynamic account configuration variables (including dynamicAccountSelection, dynamicAccountMatch, and dynamicAccountList).

The following steps outline a typical migration workflow.

  1. Download the new AppMeasurement file: Access the new file by logging in to Adobe Analytics, then navigating to Admin > Code Manager. The downloaded compressed file contains a minified AppMeasurement.js file, along with Media and Integrate modules.
  2. Copy your s_code.js customizations to AppMeasurement.js: Move all the code before the DO NOT ALTER ANYTHING BELOW THIS LINE section in s_code.js to the beginning of AppMeasurement.js.
  3. Update all plug-ins: Make sure you are using the latest version of each plug-in listed in your s_code.js file. This includes the Media and Integrate modules.
  4. Deploy the AppMeasurement.js file: Upload your AppMeasurement.js file to your web server.
  5. Update script references to point to AppMeasurement.js: Make sure all pages reference AppMeasurement.js instead of s_code.js.

Example Appmeasurement code

A typical AppMeasurement.js file. Make sure that configuration variables are set above the doPlugins function.

// Initialize AppMeasurement
var s = s_gi("examplersid");

/******** VISITOR ID SERVICE CONFIG - REQUIRES VisitorAPI.js ********/;

/************************** CONFIG SECTION **************************/;
/* You may add or alter any code config here. */
s.trackDownloadLinks = true;
s.trackExternalLinks = true;
s.trackInlineStats = true;
s.linkDownloadFileTypes = "exe,zip,wav,mp3,mov,mpg,avi,wmv,pdf,doc,docx,xls,xlsx,ppt,pptx";
s.linkInternalFilters = "javascript:,example.com";

s.usePlugins = true;
function s_doPlugins(s) {

// Use implementation plug-ins that are defined below in this section

s.doPlugins = s_doPlugins;

/* WARNING: Changing any of the below variables will cause drastic
changes to how your visitor data is collected.  Changes should only be
made when instructed to do so by your account manager.*/

/************************** PLUGINS SECTION *************************/

// Copy and paste implementation plug-ins here. Plug-ins can then be used in the s_doPlugins(s) function above

/****************************** MODULES *****************************/

// Copy and paste implementation modules (Media, Integrate) here.

/* ============== DO NOT ALTER ANYTHING BELOW THIS LINE ! ===============  */

Example page code

Typical code that loads on each page.

<script src="AppMeasurement.js"></script>
<script language="JavaScript" type="text/javascript">
s.pageName = "Example page name";
s.eVar1 = "Example eVar value";
s.events = "event1";

Make sure that you have also included a reference to AppMeasurement.js and VisitorAPI.js on each page. See JavaScript Implementation for more information.
