Book Service Example

Technical spec

• Micronaut https://micronaut.io/
• Kotlin https://kotlinlang.org/

  Should I use JOOQ or Micronaut Data instead of this???

• Skaffold

How to run

minikube start
skaffold dev -p local --port-forward

You can access

• Micronaut API Server

  mysql -u user -P 9000 -D bookman -p
  Password is password.

API Endpoints

Here are API Endpoints.

Files example/*.http contains example requests.
I use REST Client https://marketplace.visualstudio.com/items?itemName=humao.rest-client

micronaut-openapi generates swagger spec files.
But, I want to write swagger spec, and then generate code!

Note & TODO

• Set MySQL TimeZone to UTC.
• Search implementations are awful...
  Use other solutions such as Elasticsearch in production.
• DB migration can be more cool imo.
• Cache Layer is not used now.
• Can I merge ***UseCase classes???
• Use BINARY(16) instead of VARCHAR(36) for UUID. it's mistake.
