# ember/template-no-restricted-invocations

<!-- end auto-generated rule header -->

Disallow certain components, helpers or modifiers from being used.

Use cases include:

- You bring in some addon like ember-composable-helpers, but your team deems one or many of the helpers not suitable and wants to guard against their usage
- You want to discourage use of a deprecated component

## Examples

Given a config of:

```json
["foo-bar"]
```

This rule **forbids** the following:

```hbs
{{foo-bar}}
```

```hbs
{{#foo-bar}}{{/foo-bar}}
```

```hbs
<FooBar />
```

## Configuration

One of these:

- string[] - helpers or components to disallow (using kebab-case names like `nested-scope/component-name`)
- object[] - with the following keys:
  - `names` - string[] - helpers or components to disallow (using kebab-case names like `nested-scope/component-name`)
  - `message` - string - custom error message to report for violations (typically a deprecation notice / explanation of why not to use it and a recommended replacement)
