Zero-to-Running Developer Environment

Clone → Single Command → Running App in 3-5 Minutes

A complete multi-service development environment that "just works"

Quick Start

Get Started in 3 Steps

# 1. Clone and install
git clone <your-repo-url>
cd wander-dev-env
make install

# 2. Configure environment
cp .env.local.example .env

# 3. Start developing
make dev

Visit http://localhost:3000 - Your app is running!

Total time: 3-5 minutes (2-3 min install + ~20s startup)

Alternative: Interactive Setup

./setup.sh  # Installs Docker if needed, guides you through setup

Diagnostic Tools

make doctor  # Check your environment (Docker, ports, config)
make health  # Verify all services are running

Supported Platforms

  • macOS 12+ (Intel & Apple Silicon)
  • Linux Ubuntu 20.04+, Debian 11+
  • Docker Desktop 4.0+ or Colima 0.5+

Required tools: lsof (port diagnostics), pnpm (dependency management)

What You Get

The Complete Stack

Service URL Technology Stack Purpose
Frontend http://localhost:3000 React 18 + TypeScript + Vite + Tailwind CSS v4 User interface with hot reload
API http://localhost:8000 Node.js 20 + TypeScript + Express REST endpoints, business logic
Database localhost:5432 PostgreSQL 16 Persistent data storage
Cache localhost:6379 Redis 7 Session cache, performance
Health Check http://localhost:8000/health Built-in endpoint Service status monitoring
Node Debugger localhost:9229 Node.js inspector Backend debugging

Key Features

  • Hot reload for both frontend and API
  • Automatic health checks ensure everything works
  • Structured error messages with troubleshooting hints
  • Secure defaults for local development
  • Fully containerized (no global npm installs)
  • Optimized startup (~20 seconds total)
  • Developer tools (debugger ports, shell access)

Service Startup Flow

PostgreSQL → Ready (3s)
    ↓
Redis → Ready (2s)
    ↓
API → Migrations → Ready (10s)
    ↓
Frontend → Ready (5s)

All Healthy [READY] (~20s total)

Available Commands

Run make help to see all commands with descriptions.

Core Development Commands

Command Description Time*
make install Install dependencies for api/ and frontend/ ~2-3 min
make doctor Diagnose environment issues (Docker, ports, config) <0.1s
make dev Start all services (checks prerequisites, validates config) ~20s
make down Stop services (preserves database data in volumes) ~1s
make restart Quick restart (down + dev, preserves data) ~18s
make reset Fresh start - stops services and deletes all database data ~24s
make health Check if all services are healthy (with detailed output) <0.1s

Note: Times measured on Apple M1 MacBook Pro with cached Docker images. First-time runs will be slower due to image downloads.

Monitoring & Debugging

Command Description
make logs Tail logs from all services
make logs-api View API logs only
make logs-frontend View frontend logs only
make logs-db View PostgreSQL logs
make logs-redis View Redis logs
make shell-api Open shell in API container
make shell-db Open PostgreSQL psql shell

Database Management

Command Description
make migrate Run database migrations (happens automatically on startup)
make migrate-rollback Rollback last migration
make seed Load test data (5 users, 8 posts) - OPTIONAL, run manually

Testing & Quality

Command Description
make test Run all tests (API + frontend)
make test-api Run API tests only
make test-frontend Run frontend tests only
make lint Run linters on all code
make setup-vscode Setup VS Code workspace (extensions, debugger, settings)
make setup-hooks Install optional pre-commit hooks (runs lint + test before commits)

Cleanup

Command Description Data Loss?
make down Stop services No - data preserved
make clean Stop + remove volumes Yes - DB data deleted
make nuke Remove everything (images, volumes, containers) Yes - everything deleted
./teardown.sh Interactive cleanup with options User choice

Deployment

Command Description
make k8s-setup Setup local Kubernetes with Minikube
make k8s-deploy Deploy application to local Kubernetes
make k8s-teardown Remove local Kubernetes deployment
make gke-prereqs Check/install GKE prerequisites (gcloud, kubectl, helm)
make gke-setup Setup Google Kubernetes Engine cluster
make gke-deploy Deploy application to GKE
make gke-teardown Delete GKE cluster (stops billing)

Configuration

Environment Variables

Configuration is in .env file. Two options:

Option 1: Quick Start (Recommended for Local Dev)

cp .env.local.example .env

Uses safe defaults. Start immediately with make dev.

What you get:

  • Pre-configured passwords for local dev
  • All ports set to standards (3000, 8000, 5432, 6379)
  • Ready to run immediately
  • Perfect for: Getting started quickly, daily development

Option 2: Custom Configuration

cp .env.example .env
# Edit .env and replace CHANGE_ME values
make validate-secrets  # Verify no CHANGE_ME left
make dev

What you get:

  • Full control over all settings
  • Custom ports if defaults conflict
  • Production-like secret management
  • Perfect for: Complex setups, learning deployment patterns

Configuration Variables

Variable Default Description Required?
POSTGRES_DB wander Database name No
POSTGRES_USER wander_user Database username No
POSTGRES_PASSWORD (in .env) Database password Yes
POSTGRES_PORT 5432 PostgreSQL port No
REDIS_PASSWORD (in .env) Redis password Yes
REDIS_PORT 6379 Redis port No
API_PORT 8000 API HTTP port No
DEBUG_PORT 9229 Node debugger port No
FRONTEND_PORT 3000 Frontend dev server port No
API_SECRET (in .env) API encryption key Yes
JWT_SECRET (in .env) JWT token secret Yes
NODE_ENV development Environment mode No

Security Best Practices

Local Development:

  • Simple passwords are fine (e.g., dev_password_123)
  • .env is git-ignored automatically
  • Use .env.local.example for quick setup

Production:

  • Generate strong secrets: openssl rand -base64 32
  • Use environment variable injection (K8s secrets, cloud provider secrets)
  • Never commit .env files to git
  • Rotate secrets regularly
