Project Overview​

Architecture​

CSP Kit follows a data-package separation approach inspired by browserslist:

┌─────────────────┐    ┌─────────────────┐    ┌─────────────────┐
│   generator     │    │   data          │    │   cli           │

Key Design Principles​

  1. Service-First: Abstract CSP complexity through service definitions
  2. Version Awareness: Support multiple service versions with deprecation
  3. Community Driven: Enable community contributions through automation
  4. Developer Experience: Prioritize ease of use and clear documentation
  5. Security by Default: Conservative defaults with explicit opt-ins

  3. Response Time Goals:

    • Security issues: 24 hours
    • Service updates: 48 hours
    • Bug reports: 72 hours
    • Feature requests: 1 week

Service Management​

Adding New Services​

Validation Process:

  1. Official Documentation: Verify CSP requirements from official sources
  2. Testing: Test CSP rules with actual service implementation
  3. Community Need: Ensure service has sufficient community demand
  4. Maintenance: Consider long-term maintenance requirements

Service Definition Quality Standards:

{
  // Required fields - must be complete and accurate
  "id": "kebab-case-identifier",
  "name": "Human Readable Name",
  "category": "valid-category",
  "description": "Clear, concise description (50-150 chars)",
  "website": "https://official-website.com",
  "officialDocs": ["https://official-csp-docs.com"],

  // Version management - must support versioning
  "versions": {
    "1.0.0": {
      "csp": { /* validated CSP rules */ },
      "validFrom": "YYYY-MM-DD",
      "notes": ["Implementation details"],
      "requiresDynamic": boolean,
      "requiresNonce": boolean
    }
  },
  "defaultVersion": "1.0.0",

  // Optional but recommended
  "aliases": ["common-aliases"],
  "monitoring": {
    "testUrls": ["https://testable-urls.com"],
    "checkInterval": "weekly|monthly",
    "alertOnBreaking": true
  }
}

Updating Existing Services​

Update Triggers:

  1. Automated Monitoring: GitHub Actions detect changes
  2. Community Reports: Issues from users
  3. Service Announcements: Official service updates
  4. Security Advisories: CSP-related security updates

Update Process:

  1. Verify Change: Confirm CSP requirement changes
  2. Version Strategy:
    • Patch: Bug fixes, clarifications
    • Minor: New optional CSP rules
    • Major: Breaking changes to CSP rules
  3. Documentation: Update notes and migration guides
  4. Testing: Validate new requirements
  5. Deprecation: Mark old versions if needed

Version Management Strategy​

Service Versioning:

  • Semantic Versions (1.0.0): For library-specific integrations
  • Date Versions (2024-01-15): For service infrastructure changes
  • Breaking Changes: Always increment major version
  • Deprecation: 6-month deprecation period before removal

Example Scenarios:

// Scenario 1: Service adds new optional domain
"1.1.0": {
  "csp": {
    "script-src": ["https://cdn.service.com", "https://cdn2.service.com"],
    "connect-src": ["https://api.service.com"]
  },
  "validFrom": "2024-01-15",
  "breaking": false,
  "notes": ["Added cdn2.service.com for improved performance"]
}

// Scenario 2: Service removes support for old domain
"2.0.0": {
  "csp": {
    "script-src": ["https://new-cdn.service.com"],
    "connect-src": ["https://api.service.com"]
  },
  "validFrom": "2024-06-01",
  "breaking": true,
  "notes": ["Removed legacy cdn.service.com - migrate to new-cdn.service.com"]
}
