Prerequisites

• Node.js >= 22
• pnpm >= 10 (npm i -g pnpm)
• Python 3.11+ and uv (for analytics-engine only)
• Flutter 3.32+ (for mobile only)

Setup

pnpm install

All apps read from a single .env at the repo root — copy the example and fill in values:

cp .env.example .env

For analytics-engine's Python venv (first-time only):

pnpm --filter @zapengine/analytics-engine run build   # wraps `uv sync --locked`

Development

# Start frontend + account-engine + analytics-engine (typical daily dev)
pnpm dev

# Start landing page only
pnpm dev:landing

# Run the mobile app
pnpm --filter @zapengine/mobile dev

# Start everything
pnpm dev:all

All apps — including analytics-engine — run via pnpm <script>. Python scripts wrap uv run under the hood; the CLI is uniform.

For build, test, lint, and type-check commands see CLAUDE.md.

Deployment

• Backend services → Fly.io via GitHub Actions (push to main)
• Frontend / Landing → Vercel
• CI triggers on push to main and PRs; deploys only on main
