Tutorial: “Angular SpringBoot CRUD MariaDB Example”

In the tutorial, I introduce how to create an “SpringBoot Angular MariaDB CRUD Example” with POST/GET/PUT/DELETE requests to SpringBoot RestAPIs.

  • Design overview system by Architecture Diagram that includes: Angular Client, SpringBoot RestAPIs, and MariaDB database.
  • Implement Angular CRUD Client with Angular built-in HttpClient to communicate with server side.
  • Implement SpringBoot RestAPIs that gets data from MariaDB using Spring Data JPA and returns back data as Json format to requested Angular Client.

You can check out the complete code of the application on this github repository.

Angular CRUD Application is designed with 3 main layers:

  • Service Layer is used to define Angular Common Services and HttpClient Services to interact with RestAPIs
  • Component Layer is used to define Angular Components to show views in Browser for interacting with Users
  • Router Layer is used to route URLs mapping with the corresponding Angular Components

Angular Project Structure:

[caption id=“attachment_1085” align=“alignnone” width=“796”]Angular SpringBoot CRUD MariaDB Example - Angular CRUD Application - Project Structure Angular CRUD Application - Project Structure[/caption]

Angular CRUD Application defines 3 components, 2 services, 1 routers, and 2 data models:

  • Components:
  • add-customer component is used to add a new customer to system
  • list-customer component is used to show all customers on view pages, delete a customer and update a customer
  • message component is used to define a view to show logging message on browser
  • Services:
  • customer.service.ts defines POST/GET/PUT/DELETE HTTP requests to SpringBoot RestAPIs with the built-in Angular HttpClient.
  • message.service.ts defines an array storage to log all messages when Angular CRUD App running
  • Router: app-routing.module.ts defines how to map a corresponding Angular component with an URL.

  • Models:

  • customer.ts defines the main data model of our application.
  • message.ts defines the response data model between SpringBoot and Angular application.

– React.js project will consume the SpringBoot CRUD RestAPIs by Ajax then show up on Reactjs component’s views.

We build a SpringBoot project with 2 layers:
– SpringJPA Repository is used to interact with MariaDB database by a set of CRUD operations.
– RestController layer is a web layer for SpringBoot project, it will directly handle all incomming requests and do the corressponding responses to the calling client.

  • React.js components let you split the UI into independent, reusable pieces, and think about each piece in isolation.
  • Ajax is used by Reactjs component to fetch (post/put/get/delete) data from remote restapi by http request

Reactjs CRUD Application defines 5 components:

  • Home.js is used serve as the landing page for your app.
  • AppNavbar.js is used to establish a common UI feature between components.
  • CustomerList.js is used to show all customers in the web-page
  • CustomerEdit.js is used to modify the existed customer
  • App.js uses React Router to navigate between components.
