Bubble

PostHog makes it easy to get data about traffic and usage of your Bubble app. Integrating PostHog into your site enables analytics about user behavior, custom events capture, session recordings, feature flags, and more.

This guide walks you through integrating PostHog into your Bubble app using the JavaScript Web SDK.

Installation

First, sign up to PostHog. Then, go to your project settings and copy your web snippet. It looks like this:

JavaScript

<script>
    !function(t,e){var o,n,p,r;e.__SV||(window.posthog=e,e._i=[],e.init=function(i,s,a){function g(t,e){var o=e.split(".");2==o.length&&(t=t[o[0]],e=o[1]),t[e]=function(){t.push([e].concat(Array.prototype.slice.call(arguments,0)))}}(p=t.createElement("script")).type="text/javascript",p.async=!0,p.src=s.api_host+"/static/array.js",(r=t.getElementsByTagName("script")[0]).parentNode.insertBefore(p,r);var u=e;for(void 0!==a?u=e[a]=[]:a="posthog",u.people=u.people||[],u.toString=function(t){var e="posthog";return"posthog"!==a&&(e+="."+a),t||(e+=" (stub)"),e},u.people.toString=function(){return u.toString(1)+".people (stub)"},o="capture identify alias people.set people.set_once set_config register register_once unregister opt_out_capturing has_opted_out_capturing opt_in_capturing reset isFeatureEnabled onFeatureFlags getFeatureFlag getFeatureFlagPayload reloadFeatureFlags group updateEarlyAccessFeatureEnrollment getEarlyAccessFeatures getActiveMatchingSurveys getSurveys onSessionId".split(" "),n=0;n<o.length;n++)g(u,o[n]);e._i.push([i,s,a])},e.__SV=1)}(document,window.posthog||[]);
    posthog.init('<ph_project_api_key>',{api_host:https://us.i.posthog.com})
</script>

With the snippet copied, go to your Bubble site settings by clicking on the icon in the left-hand menu. If you haven’t already, sign up for at least the Starter site plan. This enables you to add custom code.

Go to the SEO / metatags tab in site settings. Paste your PostHog snippet in the Script/meta tags in header section. Then, deploy your site to live.

Capture custom events

To capture custom events, you need to install the Bubble Toolbox plugin. This enables you to run custom JavaScript code.

Below is an example of how to capture an event when a button is pressed:

Add a new button to your Bubble site. Click on the button and then on Add workflow in the popup menu.
Click on add an action. In the menu that appears, click on Plugins and then Run javascript. This will open a new menu where you can add JavaScript code.
Add the following code under the Script heading:

JavaScript

window.posthog.capture("button_clicked")
