@ffras4vnpm/laboriosam-reiciendis-porro is ESLint plugin provides linting rules for YAML.
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">
.
Requirementsvue-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.
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.
See documents.
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
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.
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.
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",
},
],
// ...
};
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",
},
},
],
// ...
};
See also https://github.com/ota-meshi/yaml-eslint-parser#readme.
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}"
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
]
}
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:
- Open the Settings/Preferences dialog, go to Languages and Frameworks | JavaScript | Code Quality Tools | ESLint, and select Automatic ESLint configuration or Manual ESLint configuration.
- 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}

The --fix
option on the command line automatically fixes problems reported by rules which have a wrench 🔧 below.
