A pipe can accept any number of optional parameters to fine-tune its output. The parameterized pipe can be created by declaring the pipe name with a colon ( : ) and then the parameter value. If the pipe accepts multiple parameters, separate the values with colons. Let’s take a birthday example with a particular format(dd/MM/yyyy):
1 2 3 4 5 6 7 8 9 | import { Component } from '@angular/core'; @Component({ selector: 'app-birthday', template: `<p>Birthday is {{ birthday | date:'dd/MM/yyyy'}}</p>` // 18/06/1987 }) export class BirthdayComponent { birthday = new Date(1987, 6, 18); } |
Note: The parameter value can be any valid template expression, such as a string literal or a component property.
