NoteApp

• this application is meant to be simple and was created to demonstrate basic simplicity / complexity and capabilities of SpringBoot framework

• it was originally written:

  • as simple as possible to make it work
  • with minimum dependencies
  • for educational purposes

• purpose of the app can be changed in the future only by the author

Dependencies included

• spring-boot-starter-web - preconfigured Spring for web, including REST, runs TomCat container

• org.projectlombok:lombok - service/logic

• jakarta.validation-api - service/logic

• com.h2database:h2 - data

• spring-boot-starter-data-jpa- data

• spring-boot-starter-thymeleaf- view ("FrondEnd")

Service layer

• lombok is used mainly to omit a need to write tons getters and setters and it's easy to understand
• jakarta.validation is used to validate inputs (e.g. to prevent creating title thousands lines long)
• Does NOT include mapstract for now (even-though mapstract reduces boiler code significantly, it does so by "hiding" the mapping logic from newcomers, and it can get into conflict with lombok requiring "bridge" to solve . Also lombok is easier to grabs on IMHO.)

Data layer

• Spring boot starter data jpa -> allows app to communicate with database(s).
• H2 includes in-memory database H2 to simplify deploying at dev's local machine
• H2 can be switched to persistent one (PostgreSQL, MySQL, ect) but it requires the database to be setup e.g. as service on local machine or on server

View aka "FrontEnd"

• includes simple thymeleaf template made frontend for demonstrating and educational purposes. It allows to experiment and learn without building standalone front end.

Testing

• Sprint boot starter test - used in testing
• JUnit5 or other testing "tools" might be used sooner or later
