Learning Project

Overview

• Learning project to explore some new tech and keep up to date on full stack stuff
  • Angular
  • Springboot
  • JPA
  • Gradle
  • Docker

  • TODO - add tooling here, IDE, java versions, git etc.

      * git setup - used windows version to have the bash
      * Starting out by installing in windows but could be interesting to use the docker stuff under ubuntu
    

First steps - Setup new machine

Java install

• What version to choose:
  • At work we're using Java8 Oracle so wouldn't mind trying out something else
  • OpenJDK11 seems like a good place to start.
  • https://en.wikipedia.org/wiki/Java_version_history
• I kept things simple, unzipped OpenJDK11 to DCDev and created JAVA_HOME and added to PATH

Gradle install

I haven't worked with it before so I have a lot to learn here.

• Guides for building different types of projects - https://gradle.org/guides/
• https://gradle.org/install/

The install for windows is done manually It seems also that the Spring gradle guide is out of date compared to the latest gradle guide where there's a gradle init to setup and standard java project structure etc.…

Start Development

Springboot

• Basic tutorial with gradle/maven etc.
  • https://spring.io/guides/gs/spring-boot/
  • https://spring.io/guides/gs/gradle/
    • really old 2.13 vs actual 5.4.1 - issues when using the gradlew commands since my JDK 11 was not compatible.

Event driven vs Reactive

• Event driven is from process based events, Reactive is data driven - reacting to the change of a data value.
