Configuration

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 eslintPluginJsonSchemaValidator from "eslint-plugin-json-schema-validator";
export default [
  // add more generic rule sets here, such as:
  // js.configs.recommended,
  ...eslintPluginJsonSchemaValidator.configs.recommended,
  {
    rules: {
      // override/add rules settings here, such as:
      // 'json-schema-validator/no-invalid': 'warn'
    },
  },
];

This plugin provides configs:

• *.configs.base ... Configuration to enable correct JSON, YAML and TOML parsing.
• *.configs.recommended ... Above, plus rule to validate with JSON Schema.

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

For backward compatibility, the flat/ prefix can still be used:

• *.configs["flat/base"] is an alias for *.configs.base
• *.configs["flat/recommended"] is an alias for *.configs.recommended

Running ESLint from the command line

If you want to run eslint from the command line, make sure you include the .json, .jsonc, .json5, .yaml, .yml and .toml extension using the --ext option or a glob pattern, because ESLint targets only .js files by default.

Examples:

eslint --ext .js,.json,.jsonc,.json5,.yaml,.yml,.toml src
eslint "src/**/*.{js,json,jsonc,json5,yaml,yml,toml}"

:computer: 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 .json, .jsonc, .json5, .yaml, .yml and .toml files, because the extension targets only *.js or *.jsx files by default.

Example .vscode/settings.json:

{
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "json",
    "jsonc",
    "json5",
    "yaml",
    "toml"
  ]
}
