In this video we will discuss deleting data on the server using Angular HttpClient service.

To issue a DELETE request, we use HttpClient service delete() method.

In employee.service.ts file, include the following deleteEmployee() method

baseUrl = 'http://localhost:3000/employees';

deleteEmployee(id: number): Observable<void> {
    return this.httpClient.delete<void>(`${this.baseUrl}/${id}`)

Code Explanation:
  • deleteEmployee() method takes the ID of the employee to delete as a parameter
  • delete() method does not return anything so we have set the return type to void
  • The URL that is passed as a parameter to the HttpClient delete() method has the ID of the employee to delete
Delete button click event handler is in DisplayEmployeeComponent. So modify deleteEmployee() method in display-employee.component.ts file as shown below.

deleteEmployee() {
    () => console.log(`Employee with ID = ${} Deleted`),
    (err) => console.log(err)

The success callback function logs the ID of the deleted employee to the console and the error callback function logs the error to the console.
