Pipe

The pipe name to use in template bindings. Typically uses lowerCamelCase because the name cannot contain hyphens.

When true, the pipe is pure, meaning that the transform() method is invoked only when its input arguments change. Pipes are pure by default.

If the pipe has internal state (that is, the result depends on state other than its arguments), set pure to false. In this case, the pipe is invoked on each change-detection cycle, even if the arguments have not changed.

Angular pipes marked as standalone do not need to be declared in an NgModule. Such pipes don't depend on any "intermediate context" of an NgModule (ex. configured providers).

More information about standalone components, directives, and pipes can be found in this guide.
