class AssetPipeline::ScriptRenderer

• AssetPipeline::ScriptRenderer
• Reference
• Object

Overview

The ScriptRenderer handles framework-agnostic JavaScript script generation and rendering. It provides advanced functionality for generating import statements, analyzing dependencies, and wrapping custom JavaScript initialization blocks in proper module script tags.

This class serves as the foundation for framework-specific renderers like StimulusRenderer.

Performance optimizations:

• Caches script content generation based on import map and custom JS hashes
• Memoizes import statement generation
• Caches dependency analysis results
