How to update this project so that it doesn't lose its cool features but stays in line with new versions of libs, removal of obsolete libs, and inclusion of newer practices. Some of the libs are 5 years old and don't get an update. Performing the tutorial becomes an ordeal due to the obsolescence of packages. If anyone has an updated version of this tutorial, it would be great to disclose, how to solve problems related to webpack, rest (which no longer exists), when.all() (3 years stopped in time), etc.
