## Build & runtime modes

The project can be built in two isolated configurations. The build scripts set the `FUNNEL_BUILD_VARIANT`/`NEXT_PUBLIC_FUNNEL_BUILD_VARIANT` environment variables so that unused code is tree-shaken during compilation.

- **Production (frontend-only)** – renders funnels using the baked JSON bundle. The admin UI and MongoDB access are not included in the bundle.
  - Development preview: `npm run dev:frontend`
  - Production build (default): `npm run build` or `npm run build:frontend`
  - Production start (default): `npm run start` or `npm run start:frontend`
- **Development (full system)** – runs the public frontend together with the admin panel backed by MongoDB.
  - Development (default): `npm run dev` or `npm run dev:full`
  - Development build: `npm run build:full`
  - Development start: `npm run start:full`

## Local development

1. Install dependencies: `npm install`
2. Choose the required mode:
   - Production preview (frontend-only): `npm run dev:frontend`
   - Full system development: `npm run dev`

The application will be available at [http://localhost:3000](http://localhost:3000).

## Production build

```bash
npm run build        # frontend-only production bundle
# or
npm run build:full   # full system development bundle
```

After building, start the chosen bundle with `npm run start` (frontend-only) or `npm run start:full`.

## Funnel Management

### Database Synchronization

To sync published funnels from MongoDB into the codebase:

```bash
# Sync all published funnels from database
npm run sync:funnels

# Preview what would be synced (dry-run mode)
npm run sync:funnels -- --dry-run

# Sync only specific funnels
npm run sync:funnels -- --funnel-ids funnel-test,ru-career-accelerator

# Keep JSON files for debugging
npm run sync:funnels -- --keep-files
```

This script:

1. Connects to MongoDB and fetches all latest published funnels
2. Saves them as temporary JSON files in `public/funnels/`
3. Bakes them into TypeScript (`src/lib/funnel/bakedFunnels.ts`)
4. Cleans up temporary JSON files

### Other Funnel Commands

```bash
# Import JSON files from public/funnels/ to MongoDB
npm run import:funnels

# Manually bake JSON files to TypeScript
npm run bake:funnels
```

**Recommended Workflow:**

1. Create/edit funnels in the admin panel
2. Publish them in the admin
3. Run `npm run sync:funnels` to update the codebase
4. Build and deploy with the latest funnels
