  2. Spring Boot + Angular 8 CRUD, Part 1 - Develop Spring Boot CRUD Rest APIs
  3. Spring Boot + Angular 8 CRUD, Part 2 - Create Angular 8 App
  4. Spring Boot + Angular 8 CRUD, Part 3 - Develop Angular 8 CRUD Operations
  5. Spring Boot + Angular 8 CRUD, Part 4 - Angular 8 CRUD App Configuration
  6. Spring Boot + Angular 8 CRUD, Part 5 - Running Angular 8 CRUD App

In this final Part 5 of Spring Boot + Angular 7 CRUD Example Tutorial, we will run an Angular 8 CRUD App.

Running Angular 8 Client Application

Let's run the above developed Angular App with a command:
ng serve
By default, the Angular app runs on 4200 port but you can change default port with the following command:
ng serve --port 4201


Hit http://localhost:4200 link in a browser will host this Angular 8 CRUD app.

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

Employee List Page

Add Employee Page

View Employee Details Page

Delete Employee

This completed the complete development of Angular 8 CRUD application with spring boot as back end.

  1. I just have cloned you git project and It is coming with error at the backend.
    POST request for "http://localhost:8080/api/v1/employees" resulted in 404 (null); invoking error handler
    Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 404 null.
    At this line
    Employee result = restTemplate.postForObject(CREATE_EMPLOYEE_ENDPOINT_URL, newEmployee, Employee.class);

    1. SpringRestClient.java file, i have created for testing REST APIs so you can delete that file or comment it out. Anyway i have removed this file from my GitHub repository. Let me know if have still issues.

  2. I cant add a employee at the frontend. When I send a request from postman to localhost:4200/add coming error like "Cannot POST /add" inside body
