# MorseQuest MVP Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Build and deploy the MorseQuest Pack 404 pilot — a Morse code learning app with mnemonic creation, audio/visual practice, and progression through Novice and Operator levels.
**Architecture:** React 18 + TypeScript (Vite) frontend served by a Node.js HTTP backend (no framework). better-sqlite3 for persistence. Magic link email auth matching the allegiance project pattern. Two-stage Docker build deployed to morsequest.keylinkit.net.
**Tech Stack:** React 18, TypeScript, Vite 5, better-sqlite3, nodemailer, Web Audio API, node:20-alpine Docker

## Task 13: Docker & Deployment Files
**Files:**
- Create: `Dockerfile`
- Create: `docker-compose.yml`
- Create: `.env.example`
- Create: `data/.gitkeep`
- [ ] **Step 1: Create `Dockerfile`**
```dockerfile
# --- Build stage ---
FROM node:20-alpine AS builder
WORKDIR /app
RUN apk add --no-cache python3 make g++
COPY package.json package-lock.json* ./
RUN npm install --no-audit --no-fund
COPY . .
RUN npm run build
# --- Runtime stage ---
FROM node:20-alpine
ENV NODE_ENV=production PORT=8080
WORKDIR /app
RUN apk add --no-cache python3 make g++
COPY package.json package-lock.json* ./
RUN npm install --omit=dev --no-audit --no-fund
COPY --from=builder /app/client/dist ./client/dist
COPY server/ ./server/
COPY assets/ ./assets/
RUN mkdir -p /app/data && chown -R node:node /app
USER node
EXPOSE 8080
HEALTHCHECK --interval=30s --timeout=5s --start-period=10s --retries=3 \
CMD wget -q --spider http://localhost:8080/ || exit 1
CMD ["node", "server/server.js"]
```
- [ ] **Step 2: Create `docker-compose.yml`**
```yaml
services:
morsequest:
image: morsequest:latest
container_name: morsequest
restart: unless-stopped
ports:
- "127.0.0.1:3004:8080"
volumes:
- morsequest-data:/app/data
environment:
PORT: "8080"
NODE_ENV: production
SMTP_HOST: mail.keylinkit.net
SMTP_PORT: "587"
SMTP_USER: ${SMTP_USER}
SMTP_PASS: ${SMTP_PASS}
ADMIN_PASSWORD: ${ADMIN_PASSWORD}
APP_URL: https://morsequest.keylinkit.net
volumes:
morsequest-data:
```
- [ ] **Step 3: Create `.env.example`**
```bash
# MorseQuest environment configuration
# Copy to .env and fill in values before running
# SMTP (magic link emails)
SMTP_HOST=mail.keylinkit.net
SMTP_PORT=587
SMTP_USER=noreply@morsequest.keylinkit.net
SMTP_PASS=your_smtp_password_here
# Admin panel password
ADMIN_PASSWORD=choose_a_strong_password
# Public URL (no trailing slash)
APP_URL=https://morsequest.keylinkit.net
# Server port (default 3001 dev, 8080 prod)
PORT=3001
```
- [ ] **Step 4: Create `data/.gitkeep`**
```bash
touch data/.gitkeep
echo "data/*.db" >> .gitignore
echo "data/*.db-*" >> .gitignore
```
- [ ] **Step 5: Verify full build**
```bash
npm run build && npm run test
```
Expected: build succeeds, all tests pass.
- [ ] **Step 6: Commit**
```bash
git add Dockerfile docker-compose.yml .env.example data/.gitkeep .gitignore
git commit -m "feat: Docker two-stage build and docker-compose for morsequest.keylinkit.net"
```
---
## Task 14: Deploy
- [ ] **Step 1: Build the Docker image on the VPS**
```bash
cd /path/to/morsequest
docker build -t morsequest:latest .
```
Expected: image builds successfully, both stages complete.
- [ ] **Step 2: Create `.env` from `.env.example` on the VPS**
```bash
cp .env.example .env
# Edit .env with real SMTP credentials and ADMIN_PASSWORD
```
- [ ] **Step 3: Start with docker-compose**
```bash
docker-compose up -d
```
Expected: container starts, health check passes after ~15s.
- [ ] **Step 4: Verify health**
```bash
docker ps | grep morsequest
docker logs morsequest --tail 20
```
Expected: container status `healthy`, server logs "MorseQuest listening on..."
- [ ] **Step 5: Configure nginx on the VPS**
Add to nginx config (matching allegiance pattern):
```nginx
server {
listen 443 ssl;
server_name morsequest.keylinkit.net;
# SSL config here (same as other keylinkit.net sites)
location / {
proxy_pass http://127.0.0.1:3004;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
```
Then: `nginx -t && systemctl reload nginx`
- [ ] **Step 6: Smoke test**
1. Visit https://morsequest.keylinkit.net — login page loads
2. Enter email → check email arrives → click link → redirected with session
3. Mnemonic builder loads → create phrase for A → save → moves to next letter
4. Complete a few letters → game page loads → Play button → audio plays + flash fires
5. Submit correct answer → score increases → mnemonic shown as hint
6. Visit https://morsequest.keylinkit.net/admin → enter ADMIN_PASSWORD → user appears in list
- [ ] **Step 7: Final commit**
```bash
git tag v0.1.0-pilot
git push origin main --tags
```
