Spring Boot + Angular 9 CRUD Example Tutorial

Go to Part 1
Hello everyone, this is my 1200th tutorial on this website and I hope you guys find this blog website useful. Read about me and follow me at https://www.javaguides.net/p/about-me.html.

In this tutorial, we will learn how to develop a CRUD (Create, Read, Update, Delete) Web 
Application using Angular 9 as a front-end and Spring boot 2 restful API as a backend.

Check out Angular 8 with spring boot 2 integration example at Spring Boot + Angular 8 CRUD Example Tutorial.

Check out Angular 7 with spring boot 2 integration example at Spring Boot 2 + Angular 7 CRUD Example.

Check out Angular 6 with spring boot 2 integration example at Spring Boot + Angular 6 CRUD Example.

You can download the source code of this tutorial from my GitHub repository at the end of this tutorial.

Check out Angular 8 + Spring Boot Basic Authentication Example - You can implement basic login and logout features in this CRUD example. All the REST calls made from Angular to Spring Boot will be authenticated using Basic Authentication.

What’s New In Angular 9?

Angular 9’s most prominent new feature is Ivy. Ivy is Angular’s new compiler and renderer. The renderer is the engine that takes your components and templates and translates them into instructions that manipulate the DOM. Ivy is an internal component, so you don’t interact with it directly. However, it can have a significant impact on your code, yielding much smaller JavaScript bundles and increasing performance.

Read more about Angular Ivy at https://angular.io/guide/ivy.

Simply put: upgrading to Angular 9 will make your web apps faster!

Other notable features in Angular 9 include:

• Enhancements to Angular CLI to support internationalization (i18n)
• Type-safe improvements to TestBed for unit testing.

To use Angular CLI’s i18n feature, you simply need to add the i18n attribute to your text elements, then run ng xi18n to extract your localizable text into a file.

• Install the latest version of Angular CLI
• Create Angular 8 client application using Angular CLI
• Identify Components, Services, and Modules
• Create Service & Components using Angular CLI
• Integrate JQuery and Bootstrap with Angular

Features Implementation

• Create an Employee

• Update an Employee

• List of Employees

• Delete Employee

• View Employee

• You will develop your first FULL STACK Application with Angular 8 and Spring Boot.

What we will build?

Basically, we will create two projects:

1. springboot2-jpa-crud-example: This project is used to develop CRUD RESTFul APIs for a simple Employee Management System using Spring Boot 2, JPA and MySQL as a database.
2. angular9-springboot-client: This project is used to develop single page application using Angular 9 as front-end technology. This Angular 9 application consumes CRUD Restful APIs developed and exposed by a springboot2-jpa-crud-example project.

Below are the screenshots shows UI of our Employee Management System App:

Employee List Page

Add Employee Page

Update Employee Page

View Employee Details Page

Delete Employee
