ember-cli-is-component

This addon provides a new helper: is-component to be used as follows:

{{is-component componentName}}

The helper returns true when the first parameter can be looked up a component; false otherwise.

Example with the {{component}} helper

The {{component}} helper throws an error when an invalid component name is given as parameter. Used with {{if}}, the (is-component) helper offers a nice failsafe to avoid the rendering error when the component may not exist:

{{#if (is-component componentName)}}
  {{component componentName}}
{{else}}
  Sorry, {{componentName}} is not a known component.
{{/if}}

Example as a computed property

isComponent: inject(),
exists: computed(function() {
  return this.get('isComponent').test('my-component');
})
