How to build a Vue cookie consent banner – PostHog tutorial
If you are a website owner, you are probably aware of the importance of obtaining consent from your visitors before using cookies to track their data. In this tutorial, we will show you how to build a cookie consent banner using Vue.js and PostHog.
Step 1: Set up your Vue project
First, make sure you have Node.js and npm installed on your machine. Then, you can create a new Vue project using the Vue CLI:
npm install -g @vue/cli
vue create vue-cookie-consent-banner
Step 2: Install PostHog
To integrate PostHog into your Vue project, you can install the PostHog JavaScript library using npm:
npm install posthog-js
Step 3: Create the CookieConsentBanner component
Now, you can create a new Vue component called CookieConsentBanner.vue, which will contain the HTML and JavaScript code for the cookie consent banner:
import posthog from 'posthog-js'
export default {
data() {
return {
showBanner: true
}
},
methods: {
acceptCookies() {
// Set a cookie to track user consent
document.cookie = "consent=accepted"
this.showBanner = false
posthog.capture('cookie_consent_given')
},
rejectCookies() {
// Set a cookie to track user rejection
document.cookie = "consent=rejected"
this.showBanner = false
posthog.capture('cookie_consent_rejected')
}
}
}
.cookie-consent-banner {
position: fixed;
bottom: 0;
left: 0;
width: 100%;
padding: 10px;
background-color: #f0f0f0;
border-top: 1px solid #ccc;
text-align: center;
}
Step 4: Integrate the component into your app
Finally, you can integrate the CookieConsentBanner component into your main Vue app. You can use the component in your App.vue file or any other relevant component:
import CookieConsentBanner from './components/CookieConsentBanner.vue'
export default {
components: {
CookieConsentBanner
}
}
And that’s it! You have now successfully built a cookie consent banner using Vue.js and integrated it with PostHog for tracking user consent. You can customize the banner’s appearance and behavior according to your website’s needs, and ensure that you are compliant with data privacy regulations.
