Browser-only import
You can also import filenamify/browser, which only imports filenamify and not filenamify.path, which relies on path being available or polyfilled. Importing filenamify this way is therefore useful when it is shipped using webpack or similar tools, and if filenamify.path is not needed.
const filenamify = require('filenamify/browser');
filenamify('<foo/bar>');
//=> 'foo!bar'
