In this lesson, we’ll explore the process of combining all of your SVG icons into one SVG sprite, to be included directly into markup. We’ll use the command line, along with the svgo and svg-sprite-generator npm packages to automate the process of compressing the SVGs and creating the sprite.
Note: This lesson assumes you have npm installed.
Install:
npm i - svgo svg-sprite-generator
Run:
svgo -f icons -o icons/out && svg-sprite-generate -d icons/out -o icons/out/sprite.svg
