SpringtBoot-Web-Application-Packt

Welcome to the SpringBoot-Web-Application repository! A Self-Learning Project for a SpringBoot Web Application using the guidelines from the "SpringBoot 3.0" book from Chapter 2 by Packt Publishing. This is a tech stack that uses Java, JavaScript & Mustache!

Update 1 | Creating a Controller

Used spring.start.io to generate a Spring Boot project quickly. Added the Spring Web dependency, which allows me to build web applications using the SpringMVC. Afterwards, I created a web controller class designed to respond to HTTP requests.

Update 2 | Adding a Mustache Template

Created a index.mustache to display contents onto a website. Updated the controller to be able to add demo data and display it onto the web page.

Update 3 | A Better Design

Updated the controller to remove it's ability to add demo data and moved the adding mechanism to the VideoService class. Refactored the controller to be able to perform constructor injection.

Update 4 | A JSON-based API & HTTP Calls

Created a new class called ApiController that is used to produce a JSON array by Jackson. Also took some time to understand the 4 different HTTP calls as follows:

  • GET calls are expected to od nothing but return data
  • POST calls are used to introduce new data to the system
  • PUT is similar to POST but is used to update existing records
  • DELETE calls are used to remove something from the server

Update 5 | JavaScript with Node.js

Made a React.js application and created the files index.js, App.js, ListOfVideos.js & NewVideo.js. Created a new mustache file called react.mustache. Updated the web controller method to be able launch to react application.
