Notice! Timeline for Breaking Changes for mParticle Web Braze Kit- 3/28/2022 - 6/14/2022

This repository will be replaced by our updated mParticle Braze Web Kit on June 14, 2022. This repo will be archived shortly after.

Braze has breaking changes between version 2.5.2 and 3.5.0 of their SDK. As a result, we too are updating our mParticle Braze web kit to support Braze’s Web SDK version 3.5.0. The updated mParticle Braze Web kit will be available via CDN on June 14, 2022 and is currently available on NPM as @mparticle/web-braze-kit v3.0.1.

How do you know if your code is affected?

You may notice errors on your site if you load mParticle via snippet (as most of our clients do), and you reference any deprecated Braze APIs starting 6/14/2022.

We highly recommend that you review the changes between version 2 and 3 of the Braze Web SDK to understand these changes, which can be found here. To summarize:

  • The appboy.ab namespace has been removed and everything lives under the appboy namespace now.
  • InAppMessage.Button has been renamed to InAppMessageButton

If you reference any of the above deprecations, you will have to makes changes to your codebase before June 14, 2022 to be compatible with both version 2 and version 3 of the Braze SDK to ensure your code continues to work. We recommend a 3 step approach. Here are some code samples of what this code could look like today (step 1), preparing for the update (step 2) and after the change is live (step 3).

The below recommendations apply only to customers who load mParticle via snippet. Customers who self host via NPM can ignore step 1 and jump straight to step 3 after updating their mParticle Braze kit to v3.0.1.

Step 1: Legacy code sample. If your code references the ab namespace (like below) or InAppMessage.Button, you should change it following Step 2’s example:

let banner = new appboy.ab.Banner(‘test’);

Step 2: Rollout code sample to be used before June 14, 2022:

let banner;
if (appboy.hasOwnProperty(‘ab’)) {
    banner = new appboy.ab.Banner(‘test’);
} else {
    banner = new appboy.Banner(‘test’);

Step 3: After June 14, 2022, you can simplify your code to the following once the mParticle Braze Web kit has been released to our CDN:

let banner = new appboy.Banner(‘test’);

Push Notifications via service-worker.js

Additionally, if you are using Push Notifications, we have updated the “service-worker.js” file. In our testing, Braze’s push notifications work as expected regardless of what version of the service-worker is used, but we recommend updating this to ensure future compatibility. In your service-worker.js file, update the code to reference instead of, ie:
