A guide on integrating a data deletion feature in Angular applications

On our website's edit page, there is a list of mat cards/workspaces with an edit icon in the top corner of each workspace. Clicking on the edit icon will take you to the edit page for that specific workspace. Within this edit page, there is a delete button that triggers a dialog box prompting the user to confirm if they want to delete the workspace.

I am currently unsure about what needs to be done for the API call.

.name.length > 0 && this.description.length > 0) {
      // Mapping data to workspace object
      this.workspace.name = this.name;
      this.workspace.description = this.description;
      this.workspace.type = WorkspaceType.public; // All workspaces are public by default

      // Creating new workspace
      this.workspaceService.createWorkspace(this.workspace).subscribe(workspace => {
        this.saving = false;
        this.gotoManage();
        this.snackbar.open(this.workspace.name + " has been created!!", "", {duration: 2500});
      }, () => this.saving = false);

    }

If you're looking to implement a similar functionality, consider the following approach:

openModalConfirmationDialog(message: TemplateRef<any>, row, progressTemplate: TemplateRef<any>, successTemplate: TemplateRef<any>) {
// Save the selected data until the page is active
  this.rowToDelete = row;
// Display the confirmation dialog
    this.modalService.open(message).then(result => {
        if (result) {
            // Open progress dialog
            this.modalService.open(progressTemplate);
            // Call custom function to delete data
            this.deleteDataAPIFunction('/name1/requestedWorkspaceDelete', row.id, successTemplate);
        }
    });
}

deleteDataAPIFunction(url, param, messageTemplate: TemplateRef<any>) { 
// Display success or error messages based on deletion outcome
 this.http.get(baseUrl + url, options)
        .subscribe(response => {
                if (response != null) {
                   // Success message for delete operation
                } else {
                    // Error message for failed delete operation
                }
            }

}

Add this code to your HTML delete button event:

(click)="openModalConfirmationDialog(confirmDialog, row, deletionInProgress, deletionSuccess)"

The above function references dialogs that are passed as parameters:

<ng-template #confirmDialog>
    <custom-directive>
        <p>Confirm delete operation</p>
        <p>Delete workspace Id: <B>{{workspace.id}}
            <br></B><B>{{moreDetails}}</B>
    </custom-directive>
</ng-template>

<ng-template #deletionInProgress>
    <custom-directive type="warning" warningTitle="Deletion in progress">
    </custom-directive>
</ng-template>

 <ng-template #deletionSuccess>
    <custom-directive type="success" successTitle="Success" btn="Close">
        <div>Workspace ID: {{workspace.id}} has been deleted</div>
    </custom-directive>
</ng-template>

    </custom-directive>
</ng-template>
