A value of any type to convert into a JSON-format string.

Usage notes

The following component uses a JSON pipe to convert an object to JSON format, and displays the string in both formats for comparison.

@Component({
  selector: 'json-pipe',
  template: `<div>
    <p>Without JSON pipe:</p>
    <pre>{{object}}</pre>
    <p>With JSON pipe:</p>
    <pre>{{object | json}}</pre>
  </div>`
})
export class JsonPipeComponent {
  object: Object = {foo: 'bar', baz: 'qux', nested: {xyz: 3, numbers: [1, 2, 3, 4, 5]}};
}
