🎉 Environment Setup Complete!

Your dev/production environment separation is now fully configured.

What Was Created

Configuration Files

• ✅ .env.local.example — Template for local development
• ✅ .env.development.example — Template for Cloudflare preview/dev branch
• ✅ .env.production.example — Template for Cloudflare production
• ✅ src/firebase.js — Firebase initialization with auto-detection
• ✅ public/_headers — Security headers for PWA
• ✅ public/_redirects — SPA routing configuration
• ✅ wrangler.toml — Cloudflare Pages configuration

Documentation

• ✅ docs/engineering/ENVIRONMENT_SETUP.md — START HERE (step-by-step guide)
• ✅ docs/engineering/DEPLOYMENT.md — Complete deployment reference
• ✅ Updated docs/DOCS_INDEX.md with new links

Updated Files

• ✅ .gitignore — Added environment variable protection

🚀 Next Steps (Do This Now!)

1. Follow the Environment Setup Guide

Open and follow: docs/engineering/ENVIRONMENT_SETUP.md

This guide walks you through:

• Creating Firebase projects (dev + prod)
• Setting up local .env.local file
• Configuring Cloudflare Pages
• Testing your first deployment

Time: ~20 minutes

2. Install Firebase SDK

npm install firebase

3. Create Your Local Environment File

cp .env.local.example .env.local
# Then edit .env.local with your Firebase dev config

---

How It Works

Local Development

npm run dev

• Runs on localhost:5173
• Uses .env.local (your dev Firebase project)
• No deployment, just local testing

Development Environment (Staging)

git push origin dev

• Auto-deploys to Cloudflare preview URL
• Uses dev Firebase project
• Accessible to team for testing

Production Environment

git push origin main

• Auto-deploys to production URL
• Uses production Firebase project
• Live for users

Environment Separation

Environment	Git Branch	URL	Firebase Project	Config Source
Local	N/A	localhost:5173	dev	.env.local
Dev/Staging	dev	*.pages.dev (preview)	dev	Cloudflare Preview vars
Production	main	*.pages.dev (production)	prod	Cloudflare Production vars

---

Security Features

✅ Environment variables never committed (.gitignore configured) ✅ Separate Firebase projects (dev data never touches production) ✅ Security headers configured (CSP, X-Frame-Options, etc.) ✅ SPA routing works (no 404s on refresh) ✅ PWA-ready (service worker headers configured)

Quick Reference

Files You'll Edit

• .env.local — Your local dev config (create from .env.local.example)
• Cloudflare dashboard — Set environment variables for deployments

Files You Won't Touch

• .env.*.example — These are templates (committed to git)
• src/firebase.js — Auto-detects environment (no changes needed)

Important Commands

# Local development
npm run dev

# Build for production
npm run build

# Preview production build locally
npm run preview

# Deploy manually (alternative to git push)
npx wrangler pages deploy dist

---

Troubleshooting

"Firebase not initialized" error? → Check you created .env.local from .env.local.example

Build fails on Cloudflare? → Make sure you set all environment variables in Cloudflare dashboard

Wrong Firebase project connecting? → Check environment variables for Production vs Preview in Cloudflare
