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

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)

# 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 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
