Observations of the demo

The de-coupling power of the hypermedia approach is clear:

• When both client and backend follow the hypermedia approach, the backend architecture can change without also having to release a new version of the client.
• bob is a console application. What if we also had a web application as a client, a mobile app, some B2B integrations?
  • We would have to roll out new versions of each of these clients.
  • To avoid such expensive client rollouts, teams will often run multiple versions of the APIs so old clients can use keep using v1 and newer clients can use v2.
  • Some teams even include v1 in the initial release, anticipating there will be a v2
• By following the hypermedia approach APIs can evolve without versioning.
