Useful SVGO[ptimization] Tools
For those of you who are not familiar with SVGO: it is a node-js based SVG optimization tool. (SVGO is an abbreviation for SVG Optimization). It comes with a set of tools and plugins that make it a great tool that you can integrate into almost any kind of workflow. (We'll go over these tools shortly.)
However, SVGO has one disadvantage: it can easily break your SVG—especially if it is animated or scripted, the document structure will change and eventually break any animations or scripting applied.
Even with the many SVGO tools and plugins available, unfortunately, we had no way to preview the result of applying SVGO optimizations to an SVG, to tell whether they will break it or not.. until now.
