Template Variables: What Are They and How to Use Them?

If you’re into coding, you’re always looking for the next cheat code to accelerate your tech skills.

But the thing with coding is that there’s always more to learn; template variables can help you use data from one part of your template in a separate area of the template.

If you’re not already using template variables, you’re missing out on an easy way to have fail-safe code that works every time. However, learning new coding techniques isn’t always easy, so we’re here to break it down for you.

Read on for an essential guide to template variables and how to use them.

What Is a Template Variable?

In a nutshell, template variables allow you to use data from a specific part of your template in a different part of the template. They’re a simple tool to use but provide access to advanced features.

Using template variables means you can avoid creating unnecessary, extra properties because you can simply use the pre-existing data from different places in your code. Your codebase will be readable, easy to maintain, and efficient.

The user will have a more dynamic experience, and the most complex functions will appear effortless.

How to Use Template Variables

Angular is an excellent place to start, as detailed in this article on template variables. A template variable can refer to elements/DOM elements, directives, TemplateRefs, and web components.

To create an Angular template variable, add a unique identifier name to what you need to reference. To declare the template variable, you should use the # symbol.

For example: <input #email placeholder=”email address”. In this example, the unique identifier is shown with the #, and the reference is shown by the ’email’ attribute.

You can also declare a variable on a NgForm. The NgForm is a directive that helps get a reference to a different value by the reference directives name. A NgForm has the ability to track the validity and the importance of every control in the entire form.

Once you’ve created the template variable, you can use it. You should make a resource that will use it and add data using the identifier name.

Using your template variable may seem simple, but it will have a powerful effect for you on the back end, and it will improve the entire user experience; they might not know why it’s working so well, but they’ll still appreciate it.
