Formatting the Output of the Clarity Design Datepicker in Angular

As an Angular developer working with the Clarity Design system, you may find yourself needing to format dates gathered from a datepicker component in a specific way. For instance, you might need to transform a date input like 10.15.2021 into an ISO format such as 2021-10-15T17:56:30.728Z. This guide will guide you through the process of achieving this without relying on ngModel, utilizing Reactive Forms instead.

Why Use Reactive Forms?

Reactive Forms in Angular provide a way to manage the form states (valid, invalid, etc.) robustly and reactively. This makes it highly preferred for complex scenarios, including but not limited to the following:

Better handling of complex validation scenarios

Distinguishing validation status easily

Monitoring value changes over time

In this guide, we'll break down how to properly format dates collected from the Clarity Design Datepicker using Reactive Forms.

Setting Up Your Form

First, let's take a look at the HTML structure of your form:

Transforming the Date Format

The Challenge

By default, date inputs may not give you the formatting you need since they typically render in a format other than ISO. Our goal is to transform an input like 10.15.2021 into 2021-10-15T00:00:00.

The Solution

After some troubleshooting, we found a straightforward method to achieve the desired date format:

Capture the date input.
Start by setting a date as a controlled value:

Conclusion

In this guide, we've shown you an effective way to format dates from the Clarity Design Datepicker in Angular without relying on ngModel by utilizing the power of Reactive Forms. By capturing and manipulating the date string correctly, you can meet the unique formatting requirements of your application effortlessly.



Now you should be equipped to handle date formatting with clarity and confidence. Happy coding!
