no-index-component-invocation

✅ The extends: 'recommended' property in a configuration file enables this rule.

Components and Component Templates can be structured as app/components/foo-bar/index.js and app/components/foo-bar/index.hbs. This allows additional files related to the component (such as a README.md file) to be co-located on the filesystem.

For template-only components, they can be either app/components/foo-bar.hbs or app/components/foo-bar/index.hbs without a corresponding JavaScript file.

Similarly, for addons, templates can be placed inside addon/components with the same rules laid out above.

In all of these case, if a template file is present in app/components or addon/components, it will take precedence over any corresponding template files in app/templates, the layout property on classic components, or a template with the same name that is made available with the resolver API. Instead of being resolved at runtime, a template in app/components will be associated with the component's JavaScript class at build time.

Examples

This rule forbids the following:

<Foo::Index />
{{component "foo/index"}}
{{foo/index}}

This rule allows the following:

<Foo />
{{component "foo"}}
{{foo}}

Migration

  • replace all ::Index> to >
  • replace all /index}} to }}
