webpack.release.config.js

// The release webpack config exports three configs:
// 1. entryConfig - generates okta-sign-in.entry.js, a non-minified built
//    version of the widget that does not include any vendor dependencies. This
//    is meant to be imported through a require() statement using webpack or
//    browserify.
// 2. cdnConfig - generates okta.sign-in.min.js, a minified built version of the
//    widget that includes everything necessary to run (including all vendor
//    libraries)
// 3. noJqueryConfig - generates okta.sign-in.no-jquery.js, which is used by
//    our own internal login flow. We can remove this once we update loginpage
//    to use webpack.
