TypeScript for WebPack configuration (FE and BE)

Legend

When the project was born, everyone liked it. A white sheet of paper and everyone looked at it with expectation and imagined what prospects would open up, what problems would be solved.

The architect put the first block on the paper. There was swearing from behind. These are the developers, arguing: How best to start a new service and which starter to choose.
