mParticle Javascript SDK

Hello! This is the public repo of the mParticle Javascript SDK. We've built the mParticle platform to take a new approach to web and mobile app data and the platform has grown to support 50+ services and SDKs, including developer tools, analytics, attribution, messaging, and advertising services. mParticle is designed to serve as the connector between all of these services - check out our site, or hit us at to learn more.

Include and Initialize the SDK

1. Customize the SDK

You can customize the SDK by setting the mParticle.config object prior to the SDK-download snippet.

mParticle.config = {
   isDevelopmentMode: true,
   identifyRequest: {
      userIdentities: { email: '', customerid: '123456' }
   identityCallback: myIdentityCallback

2. Include the SDK

To integrate the SDK add the following snippet to your site after customizing mParticle.config, ideally in the <head> element. Replace YOUR_API_KEY with the API key for your mParticle Web workspace.

<script type="text/javascript">
    (function (apiKey) {
        window.mParticle = window.mParticle || {EventType:{ Unknown:0,Navigation:1,Location:2,Search:3,Transaction:4,UserContent:5,UserPreference:6,Social:7,Other:8}};
        window.mParticle.eCommerce = { Cart: {} };
        window.mParticle.Identity = {};
        window.mParticle.config = window.mParticle.config || {};
        window.mParticle.config.rq = [];
        window.mParticle.ready = function (f) {

        function a(o,t){return function(){t&&(o=t+'.'+o);var;e.unshift(o),window.mParticle.config.rq.push(e)}}var x=['endSession','logError','logEvent','logForm','logLink','logPageView','setSessionAttribute','setAppName','setAppVersion','setOptOut','setPosition','startNewSession','startTrackingLocation','stopTrackingLocation'],y=['setCurrencyCode','logCheckout'],z=['identify','login','logout','modify'];x.forEach(function(o){window.mParticle[o]=a(o)}),y.forEach(function(o){window.mParticle.eCommerce[o]=a(o,'eCommerce')}),z.forEach(function(o){window.mParticle.Identity[o]=a(o,'Identity')});

       var mp = document.createElement('script');
       mp.type = 'text/javascript';
       mp.async = true;
       mp.src = ('https:' == document.location.protocol ? 'https://jssdkcdns' : 'http://jssdkcdn') + '' + apiKey + '/mparticle.js';
       var s = document.getElementsByTagName('script')[0];
       s.parentNode.insertBefore(mp, s);

You can then log events, for example, as follows:

mParticle.logEvent('Play Movie', mParticle.EventType.Navigation, {'movie_length':'127 minutes','rating':'PG'});

Creating an Integration

Similar to other mParticle SDKs, the Javascript SDK is able to automatically include, initialize, and delegate API calls to 3rd-party Javascript SDKs. If you would like to add your company as a new Javascript integration, reference the following integrations as examples:

Running the Tests

Prior to running the tests please install all dev dependencies via an npm install, and build the mParticle.js file as well as the test file by running npm run build:

$ npm install
$ npm run build
$ npm run testKarma

The test script will run all tests using Karma and ChromeHeadless, Firefox, and Safari by default. To run tests using a different browser, use the command:

$ BROWSER=[browserBrand] npm run testBrowser

where browserBrand can be Edge or IE.

Development Notes

This package comes with the NPM package pre-commit, which will run ESLint when you try to commit.
