Installation

Configuration

Installation

First, you need to pull the @kit/analytics package into your project using the CLI

bash

npx @makerkit/cli@latest plugins install

When prompted, select the PostHog package from the list of available packages. Once the command completes, you should see the packages/plugins/posthog directory in your project.

You can now import this package into your project:

bash

pnpm add "@kit/posthog@workspace:*" --filter "@kit/analytics" -D

Client Side

You can now use the PostHog plugin in the Analytics package. Update the packages/analytics/src/index.ts file as follows:

packages/analytics/src/index.ts

import { createPostHogAnalyticsService } from '@kit/posthog/client';
import { createAnalyticsManager } from './analytics-manager';
import type { AnalyticsManager } from './types';
export const analytics: AnalyticsManager = createAnalyticsManager({
 providers: {
   posthog: createPostHogAnalyticsService,
 },
});

For client side usage, please use the analytics object from the @kit/analytics package.

tsx

import { analytics } from '@kit/analytics';

Server Side

You can now use the PostHog plugin in the Analytics package. Update the packages/analytics/src/server.ts file as follows:

packages/analytics/src/server.ts

import { createPostHogAnalyticsService } from '@kit/posthog/server';
import { createAnalyticsManager } from './analytics-manager';
import type { AnalyticsManager } from './types';
export const analytics: AnalyticsManager = createAnalyticsManager({
 providers: {
   posthog: createPostHogAnalyticsService,
 },
});

For server side usage, please use the analytics object from the @kit/analytics package.

Configuration

Please add the following environment variables to your .env file:

bash

NEXT_PUBLIC_POSTHOG_KEY=phc_your_key_here
NEXT_PUBLIC_POSTHOG_HOST=https://eu.posthog.com

Optionally, add the Ingestion Rewrite for bypassing Blockers:

NEXT_PUBLIC_POSTHOG_INGESTION_URL=http://localhost:3000/ingest

Ingestion Rewrites

In your apps/web/next.config.mjs file, add the following config:

apps/web/next.config.mjs

/** @type {import('next').NextConfig} */
const config = {
 // ...other config
 // This is required to support PostHog trailing slash API requests
 skipTrailingSlashRedirect: true,
 async rewrites() {
   // NOTE: change `eu` to `us` if applicable
   return [
     {
       source: '/ingest/static/:path*',
       destination: 'https://eu-assets.i.posthog.com/static/:path*'
     },
     {
       source: '/ingest/:path*',
       destination: 'https://eu.i.posthog.com/:path*'
     }
   ];
 }
}

CSRF Exclusion

In your apps/web/middleware.ts file, exclude the PostHog ingestion URL from CSRF protection:

apps/web/middleware.ts

export const config = {
 matcher: ['/((?!_next/static|_next/image|images|locales|assets|ingest/*|api/*).*)'],
