ember/template-require-valid-named-block-naming-format

April 20, 2026 · View on GitHub

💼 This rule is enabled in the 📋 template-lint-migration config.

🔧 This rule is automatically fixable by the --fix CLI option.

Require named blocks to use a valid naming format (camelCase or kebab-case).

The default naming format used is camelCase.

Examples

This rule forbids the following when the camelCase naming format is enabled:

<template>
  {{yield to="foo-bar"}}
  {{has-block "foo-bar"}}
  {{if (has-block "foo-bar")}}
  {{has-block-params "foo-bar"}}
  {{if (has-block-params "foo-bar")}}
</template>

This rule allows the following when the camelCase naming format is enabled:

<template>
  {{yield to="fooBar"}}
  {{has-block "fooBar"}}
  {{if (has-block "fooBar")}}
  {{has-block-params "fooBar"}}
  {{if (has-block-params "fooBar")}}
</template>

This rule forbids the following when the kebab-case naming format is enabled:

<template>
  {{yield to="fooBar"}}
  {{has-block "fooBar"}}
  {{if (has-block "fooBar")}}
  {{has-block-params "fooBar"}}
  {{if (has-block-params "fooBar")}}
</template>

This rule allows the following when the kebab-case naming format is enabled:

<template>
  {{yield to="foo-bar"}}
  {{has-block "foo-bar"}}
  {{if (has-block "foo-bar")}}
  {{has-block-params "foo-bar"}}
  {{if (has-block-params "foo-bar")}}
</template>

Configuration

  • boolean -- true enables the rule with the default camelCase format and false disables it
  • string -- "camelCase" requires the use of the camelCase naming format, and "kebab-case" requires the use of the kebab-case naming format
