  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 the 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 the UI of our Employee Management System App:

Employee List Page

Add Employee Page

Update Employee Page

View Employee Details Page

Delete Employee

This completed the complete development of the Angular 8 CRUD application with spring boot as a 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

    1. I highly recommend you to watch video tutorial of this tutorial on my youtube channel.

  3. It says invalid CORS request when i try to post a request..

  4. Hello, if I want to add Subscription List next to Employee List that has the save functionality (add, delete, and update), how I should code it? shell I repeat the same thing in app folder or what ?
    Thank you

    1. You can create a separate components in app folder for Subscription feature just like employee feature in this tutorial.

  5. when i add new employee it goes to employee list page but don't shows me the last employee i added in list. it shows only when i refresh page.

    1. everything works fine after i update the "save()" method in createEmployee component as follows :

      save() {
      .subscribe(data => {
      }, error => console.log(error));
      this.employee = new Employee();


  6. Thank You Ramesh. Everything is working fine for me. Nice tutorial

  7. Thank you. It works well.

  8. Not able to render list page
    [object Object]

  9. I open localhost:4200 but nothing shows up. No errors anywhere but I get a blank page.
