Optimizing SVGs
As conscientious developers, we want to ensure that assets are as small as possible. The easiest way to do this with SVGs is to make use of automation tools that can optimize various particulars of SVG documents. Besides obvious economies such as removing elements (for example, stripping the title and description elements), it’s also possible to perform a raft of micro-optimizations that, when added up, make for far leaner SVG assets. Presently, for this task, I would recommend SVGO (https://github.com/svg/svgo).
If you have never used SVGO before, I would recommend starting with SVGOMG (https://jakearchibald.github.io/svgomg/). It’s a browser-based version of SVGO that enables you to toggle the various optimization plugins and get instant feedback on the file savings. Remember our example star SVG markup from the beginning of this chapter? By default, that simple SVG is 489 bytes in size. By passing that through SVGO, it’s possible to get...
