Angular Pipes: Decimal, Percent, Currency, Date
Angular is a popular web application framework developed and maintained by Google. One of the many features of Angular is the ability to use pipes to transform data in templates. Pipes are a way to transform data inside template expressions. In this article, we will explore some of the built-in pipes in Angular, specifically the Decimal, Percent, Currency, and Date pipes.
Decimal Pipe
The Decimal pipe is used to format a number as a decimal number. It takes an optional argument to specify the number of digits to include after the decimal point. For example, if we have a number 3.1415926 and we want to display it with only 2 decimal places, we can use the Decimal pipe like this:
{{ 3.1415926 | number: '1.2-2' }}
Percent Pipe
The Percent pipe is used to format a number as a percentage. It multiplies the number by 100 and appends the % sign. For example, if we have a number 0.75 and we want to display it as a percentage, we can use the Percent pipe like this:
{{ 0.75 | percent }}
Currency Pipe
The Currency pipe is used to format a number as a currency. It takes an optional argument to specify the currency code and the display format. For example, if we have a number 1000 and we want to display it as USD currency, we can use the Currency pipe like this:
{{ 1000 | currency: 'USD' }}
Date Pipe
The Date pipe is used to format a date. It takes an optional argument to specify the date format. For example, if we have a date object and we want to display it in the format “dd/MM/yyyy”, we can use the Date pipe like this:
{{ dateObject | date: 'dd/MM/yyyy' }}
These are just a few examples of how to use the Decimal, Percent, Currency, and Date pipes in Angular. There are many other built-in pipes available in Angular, and you can also create your own custom pipes to meet specific formatting needs.
With the help of pipes, developers can easily transform and format data in Angular templates without having to write complex logic in the component class. This makes the presentation of data in an Angular application much more straightforward and manageable.
Overall, Angular pipes are a powerful feature that simplifies the way data is presented in templates. They provide a convenient way to format and transform data without having to write custom formatting logic in the component class, enhancing the readability and maintainability of Angular applications.
