How to batch responsive svg wrapper generation with scripts and api
- Step 1Inventory your SVG files — Run the tool's analysis mode on your assets folder. It reads every SVG, extracts the viewBox, and generates a JSON manifest with file names, dimensions, and aspect ratios.
- Step 2Choose the output format — Select the framework: React (TSX), Vue (SFC), or plain HTML. The tool generates wrapper code in the chosen format, using the aspect-ratio CSS property for modern browsers and a padding-bottom fallback.
- Step 3Run the batch generator — Execute the script. One component file is generated per SVG in the output folder. Import these components directly in your pages — no additional wrapper logic needed.
Frequently asked questions
How does the React component handle the SVG content?+
The generated React component imports the SVG as a ReactComponent using SVGR (the standard SVG-to-React transformer used by Create React App and Vite). It wraps the SVG component in a div with the correct aspect-ratio CSS, exposing a className prop for additional styling.
Can the generator handle SVGs with animations?+
Yes. The wrapper generation is purely structural — it doesn't modify the SVG content. Animated SVGs are wrapped identically to static ones. Ensure you use inline SVG embedding (not img) for animated SVGs that need CSS animation control.
How do I regenerate wrappers when SVG dimensions change?+
Run the generator again — it overwrites existing component files with updated wrappers. Add a prebuild script: 'prebuild': 'node scripts/generate-svg-wrappers.js'. The idempotent design means regenerating produces identical output if nothing changed.
Does the batch generator work with SVG sprite sheets?+
No — sprite sheets contain multiple symbols and should not be wrapped as single-aspect-ratio containers. For sprites, use the Sprite Builder tool's individual symbol wrappers. The Responsive Wrapper batch generator is designed for one-SVG-per-file assets.
