Developing a custom form validation tool using AngularJS in tandem with Django REST on the server

Currently, I am incorporating Angular on the client side to interact with a Django REST Framework backend.

To expedite the launch of the project's Alpha version, we opted to utilize server-side validation directly.

With Django REST, a JSON string is returned displaying errors corresponding to each field in a one-to-one fashion.

This functionality in Django allowed me to implement a similar feature in jQuery within minutes.

Now, the question arises – how can I achieve the same in Angular?

Example code:

form:

<label for="uname">Login:</label>
                    <div class="inputUnit" name="email">
                        <input tpye="email" class="text" name="email" ng-model="formData.email">
                    </div>
<label for="password">password:</label>
                    <div class="inputUnit">
                        <input type="password" class="text" name="password" ng-model="formData.password">
                    </div>

JSON response from the server if both fields are left empty:

{"password": ["This field is required."], "email": ["This field is required."]}

JSON response from the server when password is missing and email does not match regex:

{"password": ["This field is required."], "email": ["Enter a valid e-mail address."]}

What is the recommended approach to create a generic component that displays these errors to the user?

The desired HTML structure after showing the errors:

<label for="uname">Login:</label>
                    <div class="inputUnit" name="email">
                        <input tpye="email" class="text" name="email" ng-model="formData.email">
<label for="error">Email error here</lable>
                    </div>
<label for="password">password:</label>
                    <div class="inputUnit">
                        <input type="password" class="text" name="password" ng-model="formData.password">
<label for="error">Password error here</lable>
                    </div>
