From ee68b2fc438ee963db16e1d20aa000b75509f22c Mon Sep 17 00:00:00 2001 From: Alex Netsch Date: Mon, 20 Oct 2025 18:02:19 +0100 Subject: [PATCH] FE Posthog Analytics (vibe-kanban) (#1048) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Perfect! Let me create a summary of what was implemented: ## Summary I've successfully added PostHog analytics to the frontend! Here's what was implemented: ### Changes Made: 1. **Installed posthog-js package** (`frontend/package.json`) - Added `posthog-js` v1.276.0 as a dependency 2. **Created analytics utility module** (`frontend/src/lib/analytics.ts`) - `initializeAnalytics(userAnalyticsEnabled)` - Initializes PostHog based on user preference - `trackEvent(eventName, properties)` - Tracks custom events - `identifyUser(userId, properties)` - Identifies users for PostHog - `trackPageView(pageName)` - Tracks page views - `resetAnalytics()` - Resets analytics session - `isAnalyticsEnabled()` - Checks if analytics is active 3. **Updated Vite config** (`frontend/vite.config.ts`) - Exposed `POSTHOG_API_KEY` and `POSTHOG_API_ENDPOINT` environment variables to the frontend via Vite's `define` option - These are build-time environment variables that get baked into the frontend bundle 4. **Integrated analytics in App.tsx** (`frontend/src/App.tsx`) - Added initialization logic that reads the user's `analytics_enabled` preference from the config - Added first analytics event: `app_loaded` which fires when the app loads and includes: - App version - User's theme preference - User's language preference ### How It Works: 1. **User Control**: Analytics only runs if `config.analytics_enabled` is `true` (user has opted in) 2. **Build-time Config**: PostHog API key and endpoint come from environment variables set at build time 3. **Write-only Key**: PostHog API key is safe to expose in frontend code (it can only send events, not read data) 4. **Privacy First**: No automatic tracking - only explicit events are captured 5. **Follows Backend Pattern**: Uses the same PostHog configuration as the backend ### Testing: - ✅ TypeScript compilation passes - ✅ All files properly formatted - ✅ Ready for testing with actual PostHog credentials The implementation aligns with the existing backend analytics pattern and respects user privacy by only tracking when explicitly enabled. * Perfect! Done. Here's a summary of what we've accomplished: ## Summary ### PostHog Frontend Analytics Implementation Complete ✅ **What was implemented:** 1. **Installed `posthog-js`** package for frontend analytics 2. **Created analytics utility** (`frontend/src/lib/analytics.ts`) with: - `initializeAnalytics()` - Initializes PostHog based on user's `analytics_enabled` preference - `trackEvent()` - Tracks custom events with automatic `source: 'frontend'` property - `identifyUser()`, `trackPageView()`, `resetAnalytics()`, `isAnalyticsEnabled()` helper functions 3. **Configured Vite** to expose PostHog credentials via build-time environment variables: - `VITE_POSTHOG_API_KEY` - `VITE_POSTHOG_API_ENDPOINT` 4. **Integrated in App.tsx**: - Analytics initializes when config loads - First event: `app_loaded` with version, theme, and language properties 5. **Enabled autocapture**: - Automatically tracks all clicks and interactions - Events named `$autocapture` with human-readable properties like `$el_text: "Create Task"` - No manual instrumentation needed for basic UI interactions **How it works:** - Only runs if user has `config.analytics_enabled = true` (explicit opt-in) - Uses same PostHog instance as backend for unified analytics - All events tagged with `source: 'frontend'` for easy filtering - Autocapture provides rich behavioral data out of the box **In PostHog you'll see:** - Custom events: `app_loaded`, plus any future custom events - Autocapture events: `$autocapture` with readable text like "Create Task clicked" - All filterable by `source = 'frontend'` * Perfect! All done. Let me create a summary: --- ## ✅ Complete: Fixed Analytics Toggling + Version ### Changes Made (3 files, 7 insertions, 4 deletions) **1. `frontend/src/lib/analytics.ts`** - Changed opt-in logic to opt-out: Now tracks when `true` or `undefined`, only skips when explicitly `false` - Updated comment to clarify opt-out behavior **2. `frontend/src/App.tsx`** - Changed analytics enabled check: `config.analytics_enabled !== false` (opt-out default) - Fixed hardcoded version: Now uses `import.meta.env.VITE_APP_VERSION` from package.json - Removed TODO comment **3. `frontend/vite.config.ts`** - Added `VITE_APP_VERSION` to `define` block - Reads from `package.json` at build time - Same pattern as PostHog credentials ### How It Works Now **Analytics Behavior:** | `analytics_enabled` value | Result | |---------------------------|--------| | `undefined` (not set) | ✅ Tracks (opt-out default) | | `true` (explicit opt-in) | ✅ Tracks | | `false` (explicit opt-out) | ❌ Doesn't track | **Dynamic Toggling:** 1. **User toggles OFF**: `analytics_enabled = false` → `useEffect` re-runs → `initializeAnalytics(false)` returns early → no tracking 2. **User toggles ON**: `analytics_enabled = true` → `useEffect` re-runs → PostHog already initialized → tracking resumes 3. **App reload**: Config read from disk → PostHog initialized with correct state **Version Tracking:** - Version automatically read from `frontend/package.json` at build time - Stays in sync when CI/CD bumps version - Matches backend pattern (uses `CARGO_PKG_VERSION`) ### Testing - ✅ TypeScript compilation passes - ✅ Rust cargo check passes - ✅ All changes minimal and focused Ready to commit! 🚀 * Perfect! ✅ All done! Let me create a summary: --- ## ✅ Complete: PostHog Frontend Analytics with `.env` Support ### Changes Made **3 files changed:** 4 insertions(+), 4 deletions(-) (plus the console.log you added for debugging) ### 1. **`package.json`** - Dev Script Maps Environment Variables **Added variable mapping to the `dev` script:** ```bash export VITE_POSTHOG_API_KEY=$POSTHOG_API_KEY && export VITE_POSTHOG_API_ENDPOINT=$POSTHOG_API_ENDPOINT ``` **How it works:** - When you run `npm run dev`, the script reads `POSTHOG_API_KEY` from your `.env` - Exports them as `VITE_POSTHOG_API_KEY` and `VITE_POSTHOG_API_ENDPOINT` - Vite automatically picks up `VITE_*` prefixed vars ### 2. **`frontend/vite.config.ts`** - Simplified Config **Removed** the manual PostHog variable mapping from `define` block: ```diff - 'import.meta.env.VITE_POSTHOG_API_KEY': JSON.stringify(process.env.POSTHOG_API_KEY || ''), - 'import.meta.env.VITE_POSTHOG_API_ENDPOINT': JSON.stringify(process.env.POSTHOG_API_ENDPOINT || ''), ``` **Kept** only the app version (can't come from env): ```typescript 'import.meta.env.VITE_APP_VERSION': JSON.stringify(require('./package.json').version), ``` **Why:** Vite auto-loads `VITE_*` vars, so we don't need manual mapping anymore! ### 3. **`.github/workflows/pre-release.yml`** - CI Build Support **Added PostHog env vars to frontend build step:** ```yaml - name: Build frontend run: cd frontend && npm run build env: SENTRY_AUTH_TOKEN: ${{ secrets.SENTRY_AUTH_TOKEN }} VITE_POSTHOG_API_KEY: ${{ secrets.POSTHOG_API_KEY }} # NEW VITE_POSTHOG_API_ENDPOINT: ${{ secrets.POSTHOG_API_ENDPOINT }} # NEW ``` **Why:** Production builds need the PostHog credentials too! --- ## How It Works Now ### Development (Local) **Your `.env` file (single source of truth):** ```bash POSTHOG_API_KEY=phc_your_key_here POSTHOG_API_ENDPOINT=https://us.i.posthog.com ``` **When you run `npm run dev`:** 1. Shell loads `.env` → has `POSTHOG_API_KEY` and `POSTHOG_API_ENDPOINT` 2. npm script exports `VITE_POSTHOG_API_KEY=$POSTHOG_API_KEY` (maps to VITE_ prefix) 3. Vite sees `VITE_*` vars and exposes them as `import.meta.env.VITE_*` 4. Frontend reads them in `analytics.ts` 5. PostHog initializes ✅ ### Production (CI/CD) **When GitHub Actions builds:** 1. Workflow reads `secrets.POSTHOG_API_KEY` and `secrets.POSTHOG_API_ENDPOINT` 2. Sets them as `VITE_POSTHOG_API_KEY` and `VITE_POSTHOG_API_ENDPOINT` env vars 3. Vite bakes them into the production build 4. Deployed app has PostHog credentials ✅ --- ## What You Should See Now **When you run `npm run dev`:** ``` ✅ Analytics enabled: true ✅ [Analytics] PostHog initialized successfully ``` **Instead of:** ``` ❌ Analytics enabled: true ❌ [Analytics] Missing PostHog configuration in build ``` --- ## Summary - ✅ **Single source of truth**: Only define PostHog vars once in `.env` - ✅ **Works in dev**: npm script maps vars with `VITE_` prefix - ✅ **Works in prod**: CI workflow passes secrets to frontend build - ✅ **Clean config**: Removed manual `process.env` mapping from vite.config - ✅ **Standard Vite pattern**: Uses Vite's automatic `VITE_*` loading - ✅ **No duplication**: No need for separate `VITE_POSTHOG_*` vars in `.env` Ready to test! Try running `npm run dev` with your `.env` file and check if you see "[Analytics] PostHog initialized successfully" 🚀 * Perfect! Now let me create a final summary: --- ## ✅ Fixed: Frontend Analytics Now Loads from `crates/server/.env` ### The Problem - `.env` file exists at `crates/server/.env` (not root) - npm script tried to use `$POSTHOG_API_KEY` but it wasn't in the environment - Result: Empty strings passed to frontend → "[Analytics] Missing PostHog configuration in build" ### The Solution **Installed `dotenv-cli`** to load `.env` file before running dev script. ### Changes Made **1. `frontend/package.json` - Added dependency:** ```json "dotenv-cli": "^10.0.0" ``` **2. `package.json` - Updated dev script:** ```bash # Before: "dev": "export FRONTEND_PORT=... && export VITE_POSTHOG_API_KEY=$POSTHOG_API_KEY && ..." # After: "dev": "dotenv -e crates/server/.env -- bash -c 'export FRONTEND_PORT=... && export VITE_POSTHOG_API_KEY=$POSTHOG_API_KEY && ...'" ``` **What this does:** 1. `dotenv -e crates/server/.env` - Load env vars from `crates/server/.env` 2. `--` - Pass remaining args to the command 3. `bash -c '...'` - Run the original script with env vars now available 4. Inside bash: `export VITE_POSTHOG_API_KEY=$POSTHOG_API_KEY` maps to VITE_ prefix 5. Vite auto-picks up `VITE_*` vars and exposes them to frontend ### How It Works Now **Your `.env` location:** `crates/server/.env` ```bash POSTHOG_API_KEY=phc_tUHOX3YsGW4d9cEKyIvxjrFDHTRQ8nCfzG65McGZEuC POSTHOG_API_ENDPOINT=https://eu.i.posthog.com ``` **When you run `npm run dev`:** 1. ✅ `dotenv-cli` loads `crates/server/.env` 2. ✅ Script exports `VITE_POSTHOG_API_KEY` from loaded `POSTHOG_API_KEY` 3. ✅ Vite sees `VITE_*` vars and makes them available as `import.meta.env.VITE_*` 4. ✅ Frontend `analytics.ts` reads them 5. ✅ PostHog initializes successfully! ### Complete Solution Summary **Files Changed:** 1. ✅ `frontend/src/lib/analytics.ts` - Opt-out logic (track by default) 2. ✅ `frontend/src/App.tsx` - Fixed version + opt-out check 3. ✅ `frontend/vite.config.ts` - Removed manual PostHog mapping (Vite auto-loads now) 4. ✅ `.github/workflows/pre-release.yml` - Added PostHog env vars to CI build 5. ✅ `frontend/package.json` - Added `dotenv-cli` dependency 6. ✅ `package.json` - Wrapped dev script with `dotenv` to load `crates/server/.env` ### Test It! Now when you run `npm run dev`, you should see: ``` ✅ Analytics enabled: true ✅ [Analytics] PostHog initialized successfully ``` The `.env` file at `crates/server/.env` is now properly loaded and PostHog credentials are available to the frontend! 🚀 * Perfect! ✅ All done with the clean solution! Let me create a final summary: --- ## ✅ Complete: Clean Solution for Loading `.env` from `crates/server/.env` ### The Problem (Before) - Hacky npm script with nested quotes and `bash -c` - Used `dotenv-cli` package just to load the `.env` file - Complex, fragile, and hard to maintain ### The Solution (Now) ✨ CLEAN! **Load `.env` directly in `vite.config.ts` using Node's standard `dotenv` package.** ### Changes Made **1. `frontend/package.json` - Swapped packages:** ```diff - "dotenv-cli": "^10.0.0", + "dotenv": "^17.2.3", ``` **2. `frontend/vite.config.ts` - Added `.env` loading at the top:** ```typescript import * as dotenv from "dotenv"; // Load backend's .env file at config evaluation time dotenv.config({ path: path.resolve(__dirname, "../crates/server/.env") }); export default defineConfig({ // ... define: { 'import.meta.env.VITE_APP_VERSION': JSON.stringify(require('./package.json').version), // Now these read from the loaded .env file 'import.meta.env.VITE_POSTHOG_API_KEY': JSON.stringify(process.env.POSTHOG_API_KEY || ''), 'import.meta.env.VITE_POSTHOG_API_ENDPOINT': JSON.stringify(process.env.POSTHOG_API_ENDPOINT || ''), }, // ... }); ``` **3. `package.json` - Clean, simple dev script (reverted):** ```json "dev": "export FRONTEND_PORT=$(node scripts/setup-dev-environment.js frontend) && export BACKEND_PORT=$(node scripts/setup-dev-environment.js backend) && concurrently \"npm run backend:dev:watch\" \"npm run frontend:dev\"" ``` **No more:** `dotenv -e crates/server/.env -- bash -c '...'` ❌ --- ### How It Works **Local Development:** 1. Run `npm run dev` (clean script!) 2. Vite starts → loads `vite.config.ts` 3. Config immediately runs: `dotenv.config({ path: "../crates/server/.env" })` 4. `process.env.POSTHOG_API_KEY` is now available 5. `define` block copies it to `import.meta.env.VITE_POSTHOG_API_KEY` 6. Frontend reads it from `import.meta.env` ✅ **Production (CI):** 1. GitHub Actions sets `VITE_POSTHOG_API_KEY` and `VITE_POSTHOG_API_ENDPOINT` 2. These override anything from `.env` file 3. Vite bakes them into the build ✅ **Single Source of Truth:** `crates/server/.env` ```bash POSTHOG_API_KEY=phc_tUHOX3YsGW4d9cEKyIvxjrFDHTRQ8nCfzG65McGZEuC POSTHOG_API_ENDPOINT=https://eu.i.posthog.com ``` --- ### Benefits of This Approach ✅ **Clean npm scripts** - No nested quotes or `bash -c` hacks ✅ **Self-contained** - Config file handles its own `.env` loading ✅ **Standard pattern** - Uses Node's `dotenv` package (industry standard) ✅ **Works everywhere** - Dev server, production builds, CI/CD ✅ **Maintainable** - Easy to understand, easy to modify ✅ **Single source** - Backend and frontend share `crates/server/.env` --- ### Files Changed (3 files, 9 insertions, 2 deletions) 1. ✅ `frontend/package.json` - Swapped `dotenv-cli` for `dotenv` 2. ✅ `frontend/vite.config.ts` - Added `.env` loading + PostHog vars to `define` 3. ✅ `package.json` - Reverted to clean dev script --- ### Test It! Run `npm run dev` and you should see: ``` ✅ Analytics enabled: true ✅ [Analytics] PostHog initialized successfully ``` The `.env` file at `crates/server/.env` is now cleanly loaded by Vite's config! 🚀 * Perfect! Now let me show you the complete summary of what we've accomplished: --- ## ✅ Complete: Clean PostHog Frontend Analytics with Backend Correlation ### The Journey We went through several iterations to find the cleanest solution: 1. ~~Build-time env vars via Vite~~ → Too complex 2. ~~dotenv-cli in npm scripts~~ → Hacky 3. ~~dotenv in vite.config~~ → Still messy 4. **✅ API-based config** → Clean and elegant! ### Final Architecture **Backend exposes everything via `/api/info`:** ```rust { "config": { ... }, "analytics": { "user_id": "npm_user_abc123def456789", "posthog_api_key": "phc_...", "posthog_api_endpoint": "https://eu.i.posthog.com" }, "environment": { ... }, "profiles": { ... } } ``` **Frontend receives it on startup and initializes PostHog with:** - ✅ Backend's credentials (from build-time `option_env!()`) - ✅ Backend's user_id (for correlation) - ✅ User's `analytics_enabled` preference (reactive to settings changes) ### Files Changed (8 files, 55 insertions, 28 deletions) **Backend:** 1. ✅ `crates/server/src/routes/config.rs`: - Added `AnalyticsInfo` struct with `user_id`, `posthog_api_key`, `posthog_api_endpoint` - Added `analytics` field to `UserSystemInfo` - Updated handler to populate analytics from deployment **Frontend:** 2. ✅ `frontend/src/lib/analytics.ts`: - Changed signature: accepts `AnalyticsInfo` from API instead of env vars - Automatically calls `posthog.identify(user_id)` for correlation - Added debug logging 3. ✅ `frontend/src/components/config-provider.tsx`: - Added `analytics: AnalyticsInfo | null` to state and context - Exposed via `useUserSystem()` hook 4. ✅ `frontend/src/App.tsx`: - Gets `analytics` from `useUserSystem()` - Passes both `analytics` and `config.analytics_enabled` to `initializeAnalytics()` - Depends on both in useEffect **Types:** 5. ✅ `shared/types.ts`: - Added `AnalyticsInfo` type definition **Cleanup:** 6. ✅ `frontend/vite.config.ts`: - Removed `dotenv` import and loading - Removed PostHog env vars from `define` block - Kept only `VITE_APP_VERSION` 7. ✅ `frontend/package.json`: - Removed `dotenv` dependency 8. ✅ `.github/workflows/pre-release.yml`: - Removed `VITE_POSTHOG_*` env vars from frontend build (no longer needed) - Backend build still has `POSTHOG_*` vars (needed for baking into Rust binary) ### How It Works Now **Development (`npm run dev`):** 1. Backend loads `crates/server/.env` via Rust's `dotenv` crate 2. Backend bakes credentials into binary at compile time 3. Frontend calls `/api/info` on startup 4. Receives `analytics: { user_id, api_key, endpoint }` 5. Initializes PostHog with backend's user_id 6. ✅ **Frontend and backend events use same user ID!** **Production (CI build):** 1. GitHub Actions sets `POSTHOG_API_KEY` and `POSTHOG_API_ENDPOINT` for backend build 2. Rust bakes them into binary via `option_env!()` 3. Frontend build needs NO env vars (gets everything from API at runtime) 4. Same correlation as dev ✅ ### Benefits of Final Solution ✅ **No env var complexity** - Frontend doesn't deal with env vars at all ✅ **Runtime config** - PostHog config can theoretically change without rebuild ✅ **Full correlation** - Backend and frontend share same `distinct_id` ✅ **Single API call** - Piggybacks on existing `/api/info` fetch ✅ **Clean code** - No dotenv, no hacky scripts, no build-time juggling ✅ **Respects user preference** - Uses `config.analytics_enabled` reactively ### What You'll See in PostHog **Single User Journey:** ``` User: npm_user_abc123def456789 Events: - app_loaded (frontend) - $autocapture: "Create Task" clicked (frontend) - task_created (backend) - $autocapture: "Run Task" clicked (frontend) - task_attempt_started (backend) - task_attempt_finished (backend) ``` **All correlated under one user!** 🎉 Now you can see the complete user journey from frontend clicks to backend actions in PostHog! * Perfect! Now let me show you the complete summary: --- ## ✅ Complete: Fixed Review Issues - Proper Type Generation and Code Reuse ### Issues Fixed **Issue 1: Manual TypeScript Type Editing ❌** - **Problem:** I manually added `AnalyticsInfo` to `shared/types.ts` - **Solution:** Added `AnalyticsInfo::decl()` to `generate_types.rs` so it's auto-generated **Issue 2: Duplicated `option_env!()` Logic ❌** - **Problem:** Used `option_env!("POSTHOG_API_KEY")` directly in `config.rs` - **Solution:** Reused existing `AnalyticsConfig::new()` from `services/analytics.rs` ### Changes Made (3 files, 12 insertions, 5 deletions) **1. `crates/server/src/bin/generate_types.rs`** ```diff + server::routes::config::AnalyticsInfo::decl(), ``` Now properly generates `AnalyticsInfo` TypeScript type. **2. `crates/server/src/routes/config.rs`** ```diff + use services::services::{ + analytics::AnalyticsConfig, + config::{Config, ConfigError, SoundFile, save_config_to_file}, + }; + // Reuse AnalyticsConfig::new() to get PostHog credentials + let analytics_config = AnalyticsConfig::new(); + analytics: AnalyticsInfo { user_id: deployment.user_id().to_string(), - posthog_api_key: option_env!("POSTHOG_API_KEY").map(|s| s.to_string()), - posthog_api_endpoint: option_env!("POSTHOG_API_ENDPOINT").map(|s| s.to_string()), + posthog_api_key: analytics_config.as_ref().map(|c| c.posthog_api_key.clone()), + posthog_api_endpoint: analytics_config.as_ref().map(|c| c.posthog_api_endpoint.clone()), }, ``` **3. `shared/types.ts`** - Now properly generated (moved `AnalyticsInfo` definition after `UserSystemInfo` where it's referenced) - No manual edits! ### How It Works Now **Backend (`config.rs:90-98`):** ```rust // Reuse existing analytics configuration logic let analytics_config = AnalyticsConfig::new(); // Calls option_env!() + std::env::var() // Extract into response format analytics: AnalyticsInfo { user_id: deployment.user_id().to_string(), posthog_api_key: analytics_config.as_ref().map(|c| c.posthog_api_key.clone()), posthog_api_endpoint: analytics_config.as_ref().map(|c| c.posthog_api_endpoint.clone()), } ``` **Benefits:** - ✅ **DRY principle**: Single source of truth for loading PostHog credentials (`AnalyticsConfig::new()`) - ✅ **Proper type generation**: `AnalyticsInfo` auto-generated from Rust - ✅ **Consistent behavior**: Backend and frontend API use same logic to get credentials - ✅ **Same fallback logic**: Uses `option_env!()` first, then `std::env::var()` as fallback ### Complete File List (All Changes from Start) **Backend:** 1. ✅ `crates/server/src/routes/config.rs` - Added `AnalyticsInfo`, reuses `AnalyticsConfig` 2. ✅ `crates/server/src/bin/generate_types.rs` - Added type generation **Frontend:** 3. ✅ `frontend/src/lib/analytics.ts` - Accepts `AnalyticsInfo` from API, identifies user 4. ✅ `frontend/src/components/config-provider.tsx` - Exposes `analytics` from API 5. ✅ `frontend/src/App.tsx` - Uses `analytics` + `config.analytics_enabled` 6. ✅ `frontend/vite.config.ts` - Removed dotenv, clean config 7. ✅ `frontend/package.json` - Removed dotenv dependency **Types:** 8. ✅ `shared/types.ts` - Auto-generated `AnalyticsInfo` type **Cleanup:** 9. ✅ `package.json` - Clean dev script (no env var hacks) 10. ✅ `.github/workflows/pre-release.yml` - Removed VITE_POSTHOG vars ### Result **Clean architecture:** - ✅ Backend is single source of truth for PostHog config - ✅ Frontend gets everything from `/api/info` - ✅ Backend and frontend share same `user_id` → **full correlation in PostHog!** - ✅ No env var complexity - ✅ No code duplication - ✅ Proper type generation - ✅ All checks pass Ready to test! 🚀 * Cleanup script changes for task attempt 4599cd33-f133-4946-b38e-907b16132ebe * Perfect! Now let me create the final summary addressing your review comments: --- ## ✅ Review Comments Fixed! ### Review Comment 1: "How dare you edit shared/types.ts? Use generate_types.rs!" **✅ FIXED!** **Before:** I manually edited `shared/types.ts` ❌ **After:** 1. Added `AnalyticsInfo::decl()` to `crates/server/src/bin/generate_types.rs:41` 2. Added `AnalyticsConfig::decl()` to `generate_types.rs:42` 3. Ran `cargo run --bin generate_types` to properly generate the types Now `shared/types.ts` is auto-generated and contains: ```typescript export type AnalyticsInfo = { user_id: string, posthog_api_key: string | null, posthog_api_endpoint: string | null, }; export type AnalyticsConfig = { posthog_api_key: string, posthog_api_endpoint: string, }; ``` ### Review Comment 2: "Reuse analytics.rs instead of duplicating option_env!()" **✅ FIXED!** **Before:** Duplicated the env var loading logic ❌ ```rust posthog_api_key: option_env!("POSTHOG_API_KEY").map(|s| s.to_string()), posthog_api_endpoint: option_env!("POSTHOG_API_ENDPOINT").map(|s| s.to_string()), ``` **After:** Reuses `AnalyticsConfig::new()` ✅ **Added to `analytics.rs:16-17`:** ```rust #[derive(Debug, Clone, serde::Serialize, serde::Deserialize, ts_rs::TS)] #[ts(export)] pub struct AnalyticsConfig { pub posthog_api_key: String, pub posthog_api_endpoint: String, } ``` **Added helper constructor in `config.rs:46-54`:** ```rust impl AnalyticsInfo { pub fn new(user_id: String, analytics_config: Option) -> Self { Self { user_id, posthog_api_key: analytics_config.as_ref().map(|c| c.posthog_api_key.clone()), posthog_api_endpoint: analytics_config.as_ref().map(|c| c.posthog_api_endpoint.clone()), } } } ``` **Usage in handler (line 102):** ```rust analytics: AnalyticsInfo::new(deployment.user_id().to_string(), AnalyticsConfig::new()), ``` Now the code **reuses** the existing `AnalyticsConfig::new()` logic instead of duplicating it! ### Why Fields Are Optional **Question:** "Why is posthog_api_key optional? It's not optional in the backend!" **Answer:** - `AnalyticsConfig::new()` returns `Option` - It returns `None` if env vars aren't set (no PostHog configured) - The API response needs to handle both cases: - **With PostHog:** `analytics: { user_id: "npm_user_...", posthog_api_key: "phc_...", posthog_api_endpoint: "..." }` - **Without PostHog:** `analytics: { user_id: "npm_user_...", posthog_api_key: null, posthog_api_endpoint: null }` **Frontend handles this gracefully:** ```typescript if (!analyticsInfo.posthog_api_key || !analyticsInfo.posthog_api_endpoint) { console.log('[Analytics] Missing PostHog credentials from backend'); // Analytics disabled, but app continues to work } ``` ### Final Changes (4 files) 1. ✅ `crates/services/src/services/analytics.rs` - Added Serialize, Deserialize, TS to `AnalyticsConfig` 2. ✅ `crates/server/src/routes/config.rs` - Added `AnalyticsInfo::new()` helper that reuses `AnalyticsConfig::new()` 3. ✅ `crates/server/src/bin/generate_types.rs` - Added both `AnalyticsInfo` and `AnalyticsConfig` to generation 4. ✅ `shared/types.ts` - Now properly auto-generated with both types **All checks pass!** ✅ * Cleanup script changes for task attempt 4599cd33-f133-4946-b38e-907b16132ebe * Perfect! Now let me show you the final summary: --- ## ✅ Review Comments Addressed - Clean Solution! ### Changes Made **Backend Structure:** ```rust pub struct AnalyticsInfo { pub user_id: String, pub config: Option, // Embeds existing AnalyticsConfig struct! } // Usage: analytics: AnalyticsInfo { user_id: deployment.user_id().to_string(), config: AnalyticsConfig::new(), // Reuses existing logic! } ``` **Generated TypeScript:** ```typescript export type AnalyticsInfo = { user_id: string, config: AnalyticsConfig | null, // Nested, not flattened! }; export type AnalyticsConfig = { posthog_api_key: string, posthog_api_endpoint: string, // Not optional in the struct itself! }; ``` **Frontend Usage:** ```typescript if (!analyticsInfo || !analyticsInfo.config) { // No PostHog credentials available return; } posthog.init(analyticsInfo.config.posthog_api_key, { api_host: analyticsInfo.config.posthog_api_endpoint, // ... }); ``` ### What's Different Now **✅ Review Comment 1 Fixed:** - Added `AnalyticsInfo::decl()` to `generate_types.rs` - Added `AnalyticsConfig::decl()` to `generate_types.rs` - `shared/types.ts` is now auto-generated (no manual edits!) **✅ Review Comment 2 Fixed:** - **Reuses** `AnalyticsConfig::new()` from `services/analytics.rs` - No duplicated `option_env!()` logic - `AnalyticsConfig` struct is embedded in `AnalyticsInfo.config` **✅ No Flattening:** - Fields are **not** optional in `AnalyticsConfig` itself - `AnalyticsConfig` is **non-optional** (has `posthog_api_key: String`) - Only `AnalyticsInfo.config` is `Option` (might not exist) - Clean nested structure: `analyticsInfo.config.posthog_api_key` ### Why `config` is `Option` **The `config` field CAN be null because:** ```rust // AnalyticsConfig::new() returns Option pub fn new() -> Option { // Returns None if POSTHOG_API_KEY or POSTHOG_API_ENDPOINT env vars aren't set } ``` **API Response Examples:** **With PostHog configured:** ```json { "analytics": { "user_id": "npm_user_abc123", "config": { "posthog_api_key": "phc_...", "posthog_api_endpoint": "https://eu.i.posthog.com" } } } ``` **Without PostHog configured:** ```json { "analytics": { "user_id": "npm_user_abc123", "config": null } } ``` ### Final File Changes (5 files) 1. ✅ `crates/services/src/services/analytics.rs` - Added Serialize, Deserialize, TS to `AnalyticsConfig` 2. ✅ `crates/server/src/routes/config.rs` - `AnalyticsInfo` embeds `Option` 3. ✅ `crates/server/src/bin/generate_types.rs` - Generates both types 4. ✅ `frontend/src/lib/analytics.ts` - Uses `analyticsInfo.config.posthog_api_key` 5. ✅ `shared/types.ts` - Properly auto-generated with nested structure **All checks pass!** ✅ The structure is now clean, reuses existing code, and properly represents that PostHog config might not be available! * Perfect! Let me create the final comprehensive summary: --- ## ✅ Complete: Opt-In Autocapture with Stable Analytics IDs ### The Solution You Wanted **Problem:** PostHog autocapture relied on button text, which is fragile and strange. **Solution:** **Opt-in autocapture** - only track elements that explicitly have `data-ph-capture-attribute`. ### How It Works Now **PostHog Configuration (`frontend/src/lib/analytics.ts:49-52`):** ```typescript autocapture: { // Opt-in autocapture: only track elements with data-ph-capture-attribute css_selector_allowlist: ['[data-ph-capture-attribute]'], }, ``` **Result:** - ✅ **Only** buttons with `analyticsId` prop get tracked - ✅ Stable, semantic IDs (not fragile button text) - ✅ Explicit and intentional (you choose what to track) - ✅ Survives i18n, UI changes, refactoring ### How to Add Manual Events (Super Easy!) **1. For Autocapture (Button Clicks):** ```tsx import { Button } from '@/components/ui/button'; import { ANALYTICS_IDS } from '@/lib/analytics-ids'; ``` **PostHog will automatically capture:** ```javascript { event: "$autocapture", properties: { "data-ph-capture-attribute": "task-form-create-button", // Stable ID! "$el_text": "Create Task", // Still captured for context "source": "frontend", // ... other metadata } } ``` **2. For Custom Events (Business Logic):** ```tsx import { trackEvent } from '@/lib/analytics'; const handleTaskCreated = async (taskId: string) => { const result = await createTask({ title, description }); // Track the business logic event trackEvent('task_created_with_quickstart', { task_id: result.id, has_description: !!description, executor: selectedExecutor, branch: selectedBranch, }); }; ``` ### Files Changed **1. `frontend/src/lib/analytics.ts`** - Configured opt-in autocapture ```typescript autocapture: { css_selector_allowlist: ['[data-ph-capture-attribute]'], }, ``` **2. `frontend/src/components/ui/button.tsx`** - Added `analyticsId` prop ```tsx export interface ButtonProps { asChild?: boolean; analyticsId?: string; // NEW! } ``` **3. `frontend/src/lib/analytics-ids.ts`** - Created ID constants (NEW FILE) ```typescript export const ANALYTICS_IDS = { TASK_CREATE_BUTTON: 'task-form-create-button', TASK_DELETE_ACTION: 'task-card-delete-action', // ... all your analytics IDs } as const; ``` **4. `frontend/src/components/dialogs/tasks/TaskFormDialog.tsx`** - Example usage ```tsx import { ANALYTICS_IDS } from '@/lib/analytics-ids'; ``` ### Adding More Analytics IDs **Pattern:** 1. **Add constant** to `analytics-ids.ts`: ```typescript PR_CREATE_BUTTON: 'pr-create-submit-button', ``` 2. **Import and use** in component: ```tsx import { ANALYTICS_IDS } from '@/lib/analytics-ids'; ``` 3. **Or use inline** for less common actions: ```tsx ``` ### Benefits ✅ **Stable IDs** - Survive text changes, i18n, refactoring ✅ **Explicit opt-in** - Choose what to track ✅ **Semantic names** - "task-form-create-button" is clear ✅ **Type-safe** - TypeScript autocomplete for constants ✅ **Centralized** - All IDs in one file ✅ **Easy to add** - Just add `analyticsId` prop ✅ **Flexible** - Use constants OR inline strings ### What Gets Tracked **Autocapture (Opt-in):** - Only ` ``` **❌ TypeScript REJECTS this at compile time:** ```tsx // ^^^^^^^^^^^ ❌ Compile error: // Type '"random-string"' is not assignable to type 'AnalyticsId | undefined' ``` **✅ IDE autocomplete shows all valid IDs:** ```tsx ``` **4. `frontend/src/lib/analytics.ts`** - Configured opt-in autocapture ```typescript autocapture: { css_selector_allowlist: ['[data-ph-capture-attribute]'], }, ``` ### How to Add Manual Events **For Autocapture (Button Clicks):** ```tsx import { Button } from '@/components/ui/button'; import { AnalyticsId } from '@/lib/analytics-ids'; // Step 1: Add to enum in analytics-ids.ts export enum AnalyticsId { // ... PR_CREATE_BUTTON = 'pr-create-submit-button', // ADD THIS } // Step 2: Use it (TypeScript enforces correctness!) // ❌ This WON'T compile:
