it does 5 things in this order in an async/await fashion

  1. Verify TypeScript Setup
  2. load Custom Routes
  3. add ExportPathMap to Routes Makes next export exportPathMap work in development mode. So that the user doesn't have to define a custom server reading the exportPathMap
  4. start hotReloader
  5. records telemetry [source code]

It prepare or make the next.js code ready to use another server (In their example express) for handling SSR.
