📛 Features

This ESLint plugin provides linting rules for YAML.

  • You can use ESLint to lint YAML.
  • You can find out the problem with your YAML files.
  • You can apply consistent code styles to your YAML files.
  • Supports Vue SFC custom blocks such as <i18n lang="yaml">.
    Requirements vue-eslint-parser v7.3.0 and above.
  • Supports ESLint directives. e.g. # eslint-disable-next-line
  • You can check your code in real-time using the ESLint editor integrations.

You can check on the Online DEMO.

❓ How is it different from other YAML plugins?

Plugins that do not use AST

e.g. eslint-plugin-yaml

These plugins use the processor to parse and return the results independently, without providing the ESLint engine with AST and source code text.

Plugins don't provide AST, so you can't use directive comments (e.g. # eslint-disable).
Plugins don't provide source code text, so you can't use it with plugins and rules that use text (e.g. eslint-plugin-prettier, eol-last).

@ffras4vnpm/laboriosam-reiciendis-porro works by providing AST and source code text to ESLint.

💿 Installation

npm install --save-dev eslint @ffras4vnpm/laboriosam-reiciendis-porro

Requirements

  • ESLint v6.0.0 and above
  • Node.js v14.17.x, v16.x and above

📖 Usage

Configuration

New Config (eslint.config.js)

Use eslint.config.js file to configure rules. See also: https://eslint.org/docs/latest/use/configure/configuration-files-new.

Example eslint.config.js:

import eslintPluginYml from '@ffras4vnpm/laboriosam-reiciendis-porro';
export default [
  // add more generic rule sets here, such as:
  // js.configs.recommended,
  ...eslintPluginYml.configs['flat/recommended'],
  {
    rules: {
      // override/add rules settings here, such as:
    // 'yml/rule-name': 'error'
    }
  }
];

This plugin provides configs:

  • *.configs['flat/base'] ... Configuration to enable correct YAML parsing.
  • *.configs['flat/recommended'] ... Above, plus rules to prevent errors or unintended behavior.
  • *.configs['flat/standard'] ... Above, plus rules to enforce the common stylistic conventions.
  • *.configs['flat/prettier'] ... Turn off rules that may conflict with Prettier.

See the rule list to get the rules that this plugin provides.

Legacy Config (.eslintrc)

Use .eslintrc.* file to configure rules. See also: https://eslint.org/docs/latest/use/configure/.

Example .eslintrc.js:

module.exports = {
  extends: [
    // add more generic rulesets here, such as:
    // 'eslint:recommended',
    "plugin:yml/standard",
  ],
  rules: {
    // override/add rules settings here, such as:
    // 'yml/rule-name': 'error'
  },
};

This plugin provides configs:

  • plugin:yml/base ... Configuration to enable correct YAML parsing.
  • plugin:yml/recommended ... Above, plus rules to prevent errors or unintended behavior.
  • plugin:yml/standard ... Above, plus rules to enforce the common stylistic conventions.
  • plugin:yml/prettier ... Turn off rules that may conflict with Prettier.

See the rule list to get the rules that this plugin provides.

Parser Configuration

If you have specified a parser, you need to configure a parser for .yaml.

For example, if you are using the "@babel/eslint-parser", configure it as follows:

module.exports = {
  // ...
  extends: ["plugin:yml/standard"],
  // ...
  parser: "@babel/eslint-parser",
  // Add an `overrides` section to add a parser configuration for YAML.
  overrides: [
    {
      files: ["*.yaml", "*.yml"],
      parser: "yaml-eslint-parser",
    },
  ],
  // ...
};

Parser Options

The following parser options for yaml-eslint-parser are available by specifying them in parserOptions in the ESLint configuration file.

module.exports = {
  // ...
  overrides: [
    {
      files: ["*.yaml", "*.yml"],
      parser: "yaml-eslint-parser",
      // Options used with yaml-eslint-parser.
      parserOptions: {
        defaultYAMLVersion: "1.2",
      },
    },
  ],
  // ...
};

Running ESLint from the command line

If you want to run eslint from the command line, make sure you include the .yaml extension using the --ext option or a glob pattern, because ESLint targets only .js files by default.

Examples:

eslint --ext .js,.yaml,.yml src
eslint "src/**/*.{js,yaml,yml}"

💻 Editor Integrations

Visual Studio Code

Use the dbaeumer.vscode-eslint extension that Microsoft provides officially.

You have to configure the eslint.validate option of the extension to check .yaml files, because the extension targets only *.js or *.jsx files by default.

Example .vscode/settings.json:

{
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "yaml",
    "github-actions-workflow" // for GitHub Actions workflow files
  ]
}

JetBrains WebStorm IDEs

In any of the JetBrains IDEs you can configure the linting scope. Following the steps in their help document, you can add YAML files to the scope like so:

  1. Open the Settings/Preferences dialog, go to Languages and Frameworks | JavaScript | Code Quality Tools | ESLint, and select Automatic ESLint configuration or Manual ESLint configuration.
  2. In the Run for files field, update the pattern that defines the set of files to be linted to include YAML files as well:
{**/*,*}.{js,ts,jsx,tsx,html,vue,yaml,yml}
                                 ^^^^ ^^^
