Template Versioning Strategy

Development

Backward-compatible video template versioning and composition registry management. Use this when creating alternative video templates, modifying composition props, evolving data schemas, or maintaining multiple template versions in Root.tsx.

Template Versioning Strategy

This Skill provides Claude Code with specific guidance on how it should handle video composition and template versioning.

When to use this skill:

Creating new video template variations (V1, V2, etc.)
Modifying existing composition component props
Registering compositions in Root.tsx
Extending RenderRequest or RecapBook type definitions
Changing frame timing in composition sequences
Testing backward compatibility with old data

Instructions

Template Versioning: When creating alternative templates, version them clearly (MonthlyRecapV1, MonthlyRecapV2)
Backward Compatibility: Maintain existing template rendering capability when adding new templates
Composition Registry: Register all composition variations in Root.tsx with Remotion.registerRoot
Breaking Changes: Document breaking changes to composition props or data structure requirements
Data Schema Evolution: When extending RecapBook or RenderRequest types, add optional fields first
Frame Timing Changes: Test all sequences when modifying frame-based timing calculations
Rollback Testing: Verify old data can still render with updated compositions

Examples:

// Good: Versioned templates, backward compatible
export const MonthlyRecapV1: React.FC<MonthlyRecapProps> = (props) => {
  // Original template implementation
};

export const MonthlyRecapV2: React.FC<MonthlyRecapProps> = (props) => {
  // Enhanced template with new features
};

// Root.tsx registration
Composition({
  id: 'MonthlyRecap',
  component: MonthlyRecapV2, // Default to latest
  ...VIDEO_CONFIG,
});

Composition({
  id: 'MonthlyRecapV1',
  component: MonthlyRecapV1, // Keep v1 available
  ...VIDEO_CONFIG,
});

// Bad: Overwriting existing template, breaking backward compat
export const MonthlyRecap: React.FC = (props) => {
  // Completely different implementation that breaks old renders
};
