How to Save User Input from Angular ReactiveForm in a Variable

When you work with Angular's Reactive Forms, capturing user input can sometimes be tricky—especially if you’re trying to save that input in your component. If you've found yourself with empty variables despite submitting your form, you're not alone. Let's dive into a common issue that developers face when handling input data and how to resolve it effectively.

Understanding the Issue

The problem usually arises when trying to retrieve form values incorrectly. In your case, you're submitting a form that consists of an email and password input, but you're ending up with empty strings when trying to access those values in your component.

Common Mistake

You might be using the following code to submit the login form:

However, the variables emailLogin and passwordLogin are not being populated as you might expect. This is a common mistake when using Angular forms because the values need to be accessed differently.

The Solution

To effectively capture user input data from your React Form, you can use the getRawValue() method on your form group. Here are the steps to achieve this.

Step 1: Retrieve Form Data

You will need to update your submitLogin method as follows:
