Next.js SDK
Integrate FlashAnalytics with Next.js for client and server-side tracking.
The Next.js SDK is optimized for App Router and Pages Router projects. Use it for client-side events, server actions, and API routes without duplicating logic.
Best for
- Next.js apps with mixed client and server tracking
- Teams that want automatic route tracking
- Projects that need server-side conversions
Install
Follow the installation guide to add the SDK and configure keys.
Initialize (client)
import { fa } from '@flash-analytics/sdk';
fa.init({
appId: 'YOUR_CLIENT_ID',
});Track events
fa.track('checkout_started', {
cartTotal: 129.0,
itemCount: 3,
});Server-side events
Use the server SDK in API routes or server actions with your secret key to track conversions that do not happen in the browser.
