We use [SVGR](https://react-svgr.com) on the source SVGs to minify and convert them to React components. This conversion happens during `npm run bootstrap`.
The generated icons can automatically be bound to the theme library built into Insomnia, by following a few rules. In the source SVG:
SVGR converts these colors to `fill=''` and `fill='currentColor'` respectively. These icons are exposed via `svg-icon.js`, which sets the css `fill` and `color` of the SVG according to the required theme.
