Pipe

decorator

Decorator that marks a class as pipe and supplies configuration metadata.

API

@Pipe({
  name: string;
  pure?: boolean | undefined;
  standalone?: boolean | undefined;
})

Description

Decorator that marks a class as pipe and supplies configuration metadata.

A pipe class must implement the PipeTransform interface. For example, if the name is "myPipe", use a template binding expression such as the following:

{{ exp | myPipe }}

The result of the expression is passed to the pipe's transform() method.

A pipe must belong to an NgModule in order for it to be available to a template. To make it a member of an NgModule, list it in the declarations field of the NgModule metadata.
