AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured, multi-step procedure for integrating the PostHog SDK into a wide variety of software projects. It guides the agent through detecting the project's framework, installing the appropriate SDK, initializing the client, and configuring environment variables. By leveraging a library of framework-specific reference files, the skill ensures that PostHog is implemented according to best practices for each supported platform, including web, mobile, and backend environments.

What it does

Detects the project's framework and package manager automatically.
Installs the correct PostHog SDK for the identified platform.
Initializes the PostHog client using framework-specific patterns.
Configures environment variables for API keys and host settings.
Implements user identification logic for login and signup events.
Verifies the integration and performs necessary cleanup.

When to use it

When setting up PostHog in a project for the first time.
When reviewing pull requests that require PostHog initialization.
When migrating or adding analytics to an existing codebase.
When you need to ensure PostHog is configured consistently across different frameworks.

Advantages

Supports a broad range of frameworks and languages.
Ensures secure configuration by enforcing the use of environment variables.
Maintains consistency with existing codebase patterns.
Reduces manual effort by automating SDK installation and boilerplate setup.

Usage examples

“Add PostHog to my new Next.js project.”: The agent will detect the Next.js framework, install the PostHog SDK, and provide the necessary initialization code in the appropriate file, such as instrumentation-client.ts.
“Help me set up PostHog in our Android app.”: The agent will identify the Android environment, guide the setup in the Application class, and configure the PostHog instance with the required API keys.

Documentation by PostHog

Add PostHog SDK integration

Use this skill to add the PostHog SDK to an application. Use it when setting up PostHog for the first time, or reviewing PRs that need PostHog initialization. Covers SDK installation, provider setup, and basic configuration. Supports any framework or language.

Supported frameworks: Next.js, React, React Router, Vue, Nuxt, TanStack Start, SvelteKit, Astro, Angular, Django, Flask, FastAPI, Laravel, Ruby on Rails, Android, Swift, React Native, Expo, Node.js, and vanilla JavaScript.

Instructions

Follow these steps IN ORDER:

STEP 1: Analyze the codebase and detect the platform.

Look for dependency files (package.json, requirements.txt, Gemfile, composer.json, go.mod, etc.) to determine the framework and language.
Look for lockfiles (pnpm-lock.yaml, package-lock.json, yarn.lock, bun.lockb) to determine the package manager.
Check for existing PostHog setup. If PostHog is already installed and initialized, do not modify its code. Inform the user and skip to verification.

STEP 2: Research integration. 2.1. Find the reference file below that matches the detected framework — it is the source of truth for SDK initialization, provider setup, and configuration patterns. Read it now. 2.2. If no reference matches, fall back to your general knowledge and web search. Use posthog.com/docs as the primary search source.

STEP 3: Install the PostHog SDK.

Add the PostHog SDK package for the detected platform. Do not manually edit package.json — use the package manager's install command.
Always install packages as a background task. Don't await completion; proceed with other work immediately after starting the installation.

STEP 4: Initialize PostHog.

Follow the framework reference for where and how to initialize. This varies significantly by framework (e.g., instrumentation-client.ts for Next.js 15.3+, AppConfig.ready() for Django, create_app() for Flask).
Set up the PostHog provider/wrapper component if the framework requires one.

STEP 5: Identify users.

Add PostHog identify() calls on the client side during login and signup events.
If both frontend and backend exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to the server-side code.

STEP 6: Set up environment variables.

Store the PostHog API key and host in environment variables (e.g. .env or framework-specific env files).
Reference these environment variables in code instead of hardcoding them.

STEP 7: Verify and clean up.

Check the project for errors. Look for type checking or build scripts in package.json.
Ensure any components created were actually used.
Run any linter or prettier-like scripts found in the package.json.

Key principles

Environment variables: Always use environment variables for PostHog keys. Never hardcode them.
Minimal changes: Add PostHog code alongside existing integrations. Don't replace or restructure existing code.
Match the example: Your implementation should follow the example project's patterns as closely as possible.
Analytics contract: Treat event names, property names, and feature flag keys as part of an analytics contract. Reuse existing names and patterns found in the project. When introducing new ones, make them clear, descriptive, and consistent with existing conventions.

Nuxt.js (v3.0 to v3.6) - Docs

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

These docs are for Nuxt v3.0 to v3.6. You can see a working example of the Nuxt v3.0 integration in our Nuxt.js demo app

Setting up PostHog on the client side

Install posthog-js using your package manager:

PostHog AI

npm

npm install --save posthog-js

Yarn

yarn add posthog-js

pnpm

pnpm add posthog-js

Bun

bun add posthog-js

Add your PostHog API key and host to your nuxt.config.js file. You can find these in your project settings.

nuxt.config.js

PostHog AI

export default defineNuxtConfig({
  runtimeConfig: {
    public: {
      posthogToken: process.env.NUXT_PUBLIC_POSTHOG_TOKEN || '<ph_project_token>',
      posthogHost: process.env.NUXT_PUBLIC_POSTHOG_HOST || 'https://us.i.posthog.com',
      posthogDefaults: '2026-01-30',
    },
  }
})

Create a new plugin by creating a new file posthog.client.js in your plugins directory.

plugins/posthog.client.js

PostHog AI

import { defineNuxtPlugin, useRuntimeConfig } from '#imports'
import posthog from 'posthog-js'
export default defineNuxtPlugin(() => {
  const runtimeConfig = useRuntimeConfig()
  const posthogClient = posthog.init(runtimeConfig.public.posthogToken, {
    api_host: runtimeConfig.public.posthogHost,
    defaults: runtimeConfig.public.posthogDefaults,
    loaded: (posthog) => {
      if (import.meta.env.MODE === 'development') posthog.debug()
    },
  })
  return {
    provide: {
      posthog: () => posthogClient,
    },
  }
})

PostHog can then be accessed throughout your Nuxt.js using the provider accessor, for example:

Vue

PostHog AI

<script setup>
   const { $posthog } = useNuxtApp()
   if ($posthog) {
      const posthog = $posthog()
      posthog.capture('<event_name>')
   }
</script>

See the JavaScript SDK docs for all usable functions, such as:

Set up a reverse proxy (recommended)

We recommend setting up a reverse proxy, so that events are less likely to be intercepted by tracking blockers.

We have our own managed reverse proxy service, which is free for all PostHog Cloud users, routes through our infrastructure, and makes setting up your proxy easy.

If you don't want to use our managed service then there are several other options for creating a reverse proxy, including using Cloudflare, AWS Cloudfront, and Vercel.

Grouping products in one project (recommended)

If you have multiple customer-facing products (e.g. a marketing website + mobile app + web app), it's best to install PostHog on them all and group them in one project.

This makes it possible to track users across their entire journey (e.g. from visiting your marketing website to signing up for your product), or how they use your product across multiple platforms.

Add IPs to Firewall/WAF allowlists (recommended)

For certain features like heatmaps, your Web Application Firewall (WAF) may be blocking PostHog’s requests to your site. Add these IP addresses to your WAF allowlist or rules to let PostHog access your site.

EU: 3.75.65.221, 18.197.246.42, 3.120.223.253

US: 44.205.89.55, 52.4.194.122, 44.208.188.173

These are public, stable IPs used by PostHog services (e.g., Celery tasks for snapshots).

Setting up PostHog on the server side

Install posthog-node using your package manager:

PostHog AI

npm

npm install posthog-node --save

Yarn

yarn add posthog-node

pnpm

pnpm add posthog-node

Bun

bun add posthog-node

Add your PostHog API key and host to your nuxt.config.js file. If you've already done this when adding PostHog to the client side, you can skip this step.

nuxt.config.js

PostHog AI

export default defineNuxtConfig({
  runtimeConfig: {
    public: {
      posthogToken: '<ph_project_token>',
      posthogHost: 'https://us.i.posthog.com',
      posthogDefaults: '2026-01-30',
    }
  }
})

Initialize the PostHog Node client where you'd like to use it on the server side. For example, in a server route:

server/api/example.js

PostHog AI

const runtimeConfig = useRuntimeConfig()
  const posthog = new PostHog(
    runtimeConfig.public.posthogToken,
    {
      host: runtimeConfig.public.posthogHost,
    }
  );
  posthog.capture({
    event: 'api_call',
    distinctId: distinctId,
    properties: {
      $current_url: url,
      query: query
    }
  })
  posthog.shutdown()
  return {
    message: "example response"

Note: Make sure to always call posthog.shutdown() after capturing events from the server-side. PostHog queues events into larger batches, and this call forces all batched events to be flushed immediately.

See the Node SDK docs for all usable functions, such as:
