ember-template-lint

How CodeRabbit runs ember-template-lint to lint Ember Handlebars template files on pull requests — including supported file types, project detection, configuration, and skip conditions.

ember-template-lint is a linter for Ember and Glimmer Handlebars (.hbs) template files. It checks for accessibility violations, deprecated patterns, template anti-patterns, and style issues in Ember.js and Glimmer templates.

Files

ember-template-lint considers files with the following extensions:

• .hbs

Project detection

CodeRabbit runs ember-template-lint only when changed .hbs files appear to belong to an Ember project. A pull request is treated as Ember-related when at least one of these signals is present:

• A changed .hbs file is under a standard Ember template or component path, such as app/templates/, app/components/, addon/templates/, addon/components/, or tests/dummy/app/.
• The repository contains an Ember project marker, such as .ember-cli, ember-cli-build.js, ember-cli-build.cjs, or ember-cli-build.mjs.
• A nearby package.json or the repository-root package.json includes Ember dependencies, such as packages named ember, ember-*, or @ember/*.

This avoids running ember-template-lint on unrelated Handlebars files, such as generator templates, when the repository does not contain Ember project signals.

Configuration

ember-template-lint reads its configuration from your repository automatically. Supported config files include:

• .template-lintrc.js
• .template-lintrc.cjs
• .template-lintrc.mjs
• .template-lintrc.json
• .template-lintrc.yaml
• .template-lintrc.yml

If no config file is found, ember-template-lint runs with its default rule set.

To enable or disable ember-template-lint, use your .coderabbit.yaml file or the CodeRabbit web UI:

.coderabbit.yaml

.coderabbit.yaml

reviews:
  tools:
    emberTemplateLint:
      enabled: true

Web UI

Go to Reviews → Tools → ember-template-lint in your organization or repository settings and toggle ember-template-lint on or off.

When CodeRabbit skips ember-template-lint

CodeRabbit skips ember-template-lint when:

• No .hbs files are present in the pull request diff.
• Changed .hbs files are not under standard Ember template paths and CodeRabbit cannot find Ember project markers or Ember dependencies nearby.
• ember-template-lint is already running as a step in your CI pipeline (detected via GitHub Checks).
