 The sw-precache module has the ability to include the sw-toolbox code and configuration alongside its own configuration. Using the `runtimeCaching` configuration option in sw-precache ([see below](#runtimecaching-arrayobject)) is a shortcut that accomplishes what you could do manually by importing sw-toolbox in your service worker and writing your own routing rules.
