ember-eslint-parser

This is the eslint parser for ember's gjs and gts files (using <template>), and also for Handlebars (.hbs) template files.

It is meant to be used with eslint-plugin-ember, which provides nice defaults for all the different file types in ember projects.

It's recommended to only use overrides when defining your eslint config, so using this parser would look like this:

    {
      files: ['**/*.gjs'],
      parser: 'ember-eslint-parser',
      plugins: ['ember'],
      extends: [
        'eslint:recommended',
        'plugin:ember/recommended',
        'plugin:ember/recommended-gjs',
      ],
    },
    {
      files: ['**/*.gts'],
      parser: 'ember-eslint-parser',
      plugins: ['ember'],
      extends: [
        'eslint:recommended',
        'plugin:ember/recommended',
        'plugin:ember/recommended-gts',
      ],
    },

if we detect a typescript parser, it will also be used for all files, otherwise babel parser will be used. If we cannot find a typescript parser when linting gts we throw an error.

HBS (Handlebars) support

For .hbs template files, use the ember-eslint-parser/hbs parser. In ESLint's flat config format (ESLint 9+):

// eslint.config.mjs
import hbsParser from 'ember-eslint-parser/hbs';

export default [
  {
    files: ['**/*.hbs'],
    languageOptions: {
      parser: hbsParser,
    },
  },
];

Note: In .hbs files, all locals not defined in the template are assumed to be defined at runtime. This avoids false-positive no-undef errors for template identifiers. This is a known limitation of the classic HBS format — use .gjs/.gts for full static analysis.

Support

eslint-plugin-ember is the primary consumer of this parser library, so SemVer may not be respected for other consumers.
