@ztrehagem/svg-bundler

Generating SVG sprite. Bundle SVGs into a single SVG as a collection of symbols, and generate manifest.

Features

Specified SVG files or strings are converted into <symbol> with id attribute, and bundled into single <svg>. Furthermore, a manifest JSON is generated that has id, width, height, and viewBox attributes of each SVG. Normally the parent of <use> is a <svg>, the manifest is useful for applying their attributes to the <svg>.

This library won't optimize SVGs like SVGO, just bundle.
