What Are Angular Pipes?
Angular, offers a handy feature called
pipes. In a nutshell, pipes are short, reusable functions for transforming
and formatting data within your Angular templates.
They are versatile, offering both built-in pipes that Angular provides out
of the box, and the ability to create your own custom pipes
What Are Angular Pipes?
Angular provides several built-in pipes for common transformations, including DatePipe for formatting dates, UpperCasePipe and LowerCasePipe for capitalization, and CurrencyPipe for currency formatting, to name a few. These are readily available for use without additional setup.
Custom Pipes
Sometimes, your data needs specific transformations that aren't covered by the built-in pipes. That's where custom pipes come into play. You can create your own pipes to cater to your unique data processing requirements.
Syntax of Pipes
In your Angular templates, you can use pipes by appending a pipe operator (`|`) to the data you want to transform, followed by the pipe name. The syntax is simple and concise:
<p>{{ data | pipeName: parameter1: parameter2 }}</p>
`data`:The data you want to transform.
`pipeName`:The name of the pipe you want to apply.
`parameter1`,`parameter2`, etc.: Optional parameters that some pipes may require.
General Usage in Angular Component
Angular pipes are particularly useful within component templates. Here's how you can use a pipe within your component's template:
<!-- Using the built-in DatePipe to format a date -->
<p>{{ myDate | date: 'short' }}</p>
<!-- Applying a custom pipe called 'myCustomPipe' with a parameter -->
<p>{{ myData | myCustomPipe: parameterValue }}</p>
Whether you're working with the built-in pipes or creating your own,
Angular pipes are a powerful tool for simplifying data transformation
and enhancing your application's user experience.
So, embrace Angular pipes, and let your data shine!
