Better SVG is a VS Code extension that provides live SVG preview, inline SVG detection, and SVGO optimization. It supports a wide range of frameworks (React, Vue, Svelte, Astro, Blade, etc.) by converting JSX/TSX and framework-specific syntax to standard SVG before optimization and back. The extension includes a webview panel with zoom, pan, color picker, and dark background toggle, as well as gutter icons and hover previews for inline SVGs in code. The core logic is well-abstracted into pure modules (svgTransform, svgPreview, svgoPlugins) that are testable and potentially reusable outside the extension. The codebase is actively maintained, has comprehensive tests, and demonstrates high craftsmanship in handling edge cases like template literal interpolations, Blade directives, and multiline closing tags.
