# Phase 5 Executive Summary
**Date**: 2025-11-18
**Version**: v0.5.2 → v0.6.0
**Status**: Design Complete, Ready for Implementation
## What Is Phase 5?
Phase 5 implements two critical features for StarPunk:
1. **RSS Feed Generation**: Allow RSS readers to subscribe to your notes
2. **Production Container**: Enable deployment with HTTPS for real IndieAuth testing
## Why These Features Together?
**RSS Feed** completes the core V1 content syndication feature set. Readers can now subscribe to your notes via any RSS reader (Feedly, NewsBlur, etc.).
**Production Container** solves a critical problem: **IndieAuth requires HTTPS**. You can't properly test authentication on localhost. The container allows you to deploy StarPunk on a public server with HTTPS, enabling full IndieAuth testing with your real domain.
## What You'll Get
### 1. RSS 2.0 Feed (`/feed.xml`)
**Features**:
- Valid RSS 2.0 XML feed
- Recent 50 published notes (configurable)
- Proper RFC-822 date formatting
- Full HTML content in each entry
- Auto-discovery (RSS readers detect it automatically)
- 5-minute server-side caching for performance
**User Experience**:
```
1. You publish a note via StarPunk
2. RSS feed updates (within 5 minutes)
3. RSS readers poll your feed
4. Your subscribers see your new note
```
**Standards Compliant**:
- Validates with W3C Feed Validator
- Works with all RSS readers
- Includes proper metadata
- IndieWeb friendly
### 2. Production-Ready Container
**Features**:
- Podman and Docker compatible
- Multi-stage optimized build
- Non-root user for security
- Gunicorn WSGI server (4 workers)
- Health check endpoint
- Data persistence via volume mounts
- Environment variable configuration
- Production logging
**Deployment**:
```
1. Build container (Podman or Docker)
2. Run on public server
3. Configure reverse proxy (Caddy or Nginx)
4. HTTPS via Let's Encrypt
5. Test IndieAuth with real domain
```
**Why This Matters**:
- IndieAuth **requires** HTTPS (can't test on localhost)
- Container provides clean, reproducible deployment
- Data persists across restarts
- Easy to backup (just backup the volume)
- Professional deployment ready for production use
## File Structure
### New Files Created

```
## Current Status
### Codebase State: ✅ EXCELLENT
- **Version**: v0.5.2
- **Tests**: 405/406 passing (99.75%)
- **Coverage**: 87%
- **Code Quality**: Formatted (Black), Linted (Flake8)
- **Architecture**: Sound, well-structured
- **Dependencies**: All required dependencies already present
### Phase 4 Completion: ✅ COMPLETE
All prerequisites met:
- Web interface fully functional
- Authentication working (IndieAuth + dev mode)
- Note CRUD operations tested
- Templates with microformats
- Testing infrastructure solid
### Phase 5 Readiness: ✅ READY
No blockers identified:
- feedgen library already in requirements.txt
- Database schema supports RSS queries
- Route blueprint ready for /feed.xml
- All architectural decisions made
- Comprehensive design documentation
## Implementation Path
### Recommended Sequence
**Part 1: RSS Feed** (3-4 hours)
1. Create `starpunk/feed.py` module
2. Add `/feed.xml` route with caching
3. Update templates with RSS discovery
4. Write tests
5. Validate with W3C
**Part 2: Container** (3-4 hours)
1. Create Containerfile
2. Create compose.yaml
3. Add health check endpoint
4. Test build and run
5. Test data persistence
**Part 3: Production Testing** (2-3 hours)
1. Deploy container to public server
2. Configure reverse proxy (HTTPS)
3. Test IndieAuth authentication
4. Verify RSS feed in readers
5. Document deployment
**Part 4: Documentation** (1-2 hours)
1. Update CHANGELOG.md
2. Increment version to 0.6.0
3. Create deployment guide
4. Create implementation report
**Total Time**: 9-13 hours
## Key Design Decisions (ADR-014)
### RSS Format: RSS 2.0 Only (V1)
- **Why**: Universal support, simpler than Atom
- **Deferred**: Atom and JSON Feed to V2
### XML Generation: feedgen Library
- **Why**: Reliable, tested, produces valid XML
- **Avoided**: Manual XML (error-prone)
### Caching: 5-Minute In-Memory Cache
- **Why**: Reduces load, reasonable delay
- **Benefit**: Fast responses, ETag support
### Note Titles: First Line or Timestamp
- **Why**: Notes don't require titles (per IndieWeb)
- **Fallback**: Timestamp if no first line
### Feed Limit: 50 Items (Configurable)
- **Why**: Reasonable balance
- **Configurable**: FEED_MAX_ITEMS env variable
## Quality Gates
Phase 5 is complete when:
### Functional
- [ ] RSS feed validates with W3C validator
- [ ] Feed appears correctly in RSS readers
- [ ] Container builds (Podman + Docker)
- [ ] Health check endpoint works
- [ ] Data persists across restarts
- [ ] IndieAuth works with HTTPS
### Quality
- [ ] All tests pass (>405 tests)
- [ ] Coverage >85%
- [ ] No linting errors
- [ ] Code formatted
### Documentation
- [ ] CHANGELOG updated
- [ ] Version incremented to 0.6.0
- [ ] Deployment guide complete
- [ ] Implementation report created
## What Happens After Phase 5?
### V1 Feature Set Progress
**Completed after Phase 5**:
- ✅ Note storage and management
- ✅ IndieAuth authentication
- ✅ Web interface
- ✅ RSS feed generation
- ✅ Production deployment capability
**Remaining for V1**:
- ⏳ Micropub endpoint (Phase 6)
- ⏳ Final integration testing
- ⏳ V1.0.0 release
### Version Progression
```
v0.5.2 (current) → Phase 5 → v0.6.0 → Phase 6 → v0.7.0 → V1.0.0
RSS + Micropub Final
Container Polish
```
## Container Deployment Example
### Quick Start (Production)
```bash
# On your public server
git clone <your-repo>
cd starpunk
# Configure
cp .env.example .env
# Edit .env: Set SITE_URL, ADMIN_ME, SESSION_SECRET
# Create data directory
mkdir -p container-data/notes
# Run with Podman
podman-compose up -d
# Configure Caddy (auto-HTTPS)
# Edit Caddyfile: Set your-domain.com
caddy run
# Visit https://your-domain.com
# RSS feed: https://your-domain.com/feed.xml
# Admin: https://your-domain.com/admin/login
```
That's it! Full HTTPS, working IndieAuth, RSS feed available.
## RSS Feed Example
Once deployed, your feed will look like:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
<channel>
<title>My StarPunk Site</title>
<link>https://your-domain.com/</link>
<description>My personal IndieWeb site</description>
<item>
<title>My Latest Note</title>
<link>https://your-domain.com/note/my-latest-note</link>
<guid>https://your-domain.com/note/my-latest-note</guid>
<pubDate>Mon, 18 Nov 2024 10:30:00 +0000</pubDate>
<description><![CDATA[
<p>Full HTML content of your note here</p>
]]></description>
</item>
<!-- More items... -->
</channel>
</rss>
```
## Testing IndieAuth with Container
**Before Phase 5**: Can't test IndieAuth properly (localhost doesn't work)
**After Phase 5**:
1. Deploy container to `https://your-domain.com`
2. Set `ADMIN_ME=https://your-identity.com`
3. Visit `https://your-domain.com/admin/login`
4. Enter your identity URL
5. IndieLogin redirects you for authentication
6. Authenticate via your method (GitHub, email, etc.)
7. IndieLogin redirects back to your domain
8. **It works!** You're logged in
## Risk Mitigation
### Identified Risks & Solutions
**Risk**: RSS feed invalid XML
- **Solution**: Use feedgen library (tested)
- **Validation**: W3C validator before commit
**Risk**: Container fails to build
- **Solution**: Multi-stage build, tested locally
- **Fallback**: Can still deploy without container
**Risk**: IndieAuth callback fails
- **Solution**: Example configs provided
- **Testing**: Step-by-step testing guide
**Risk**: Data loss in container
- **Solution**: Volume mounts, tested persistence
- **Backup**: Easy to backup volume directory
