💿 Installation

npm install --save-dev eslint eslint-plugin-jsonc eslint-plugin-json-schema-validator


  • ESLint v6.0.0 and above
  • Node.js v14.18.x, v16.x and above

📖 Usage


Use .eslintrc.* file to configure rules. See also:

Example .eslintrc.js:

module.exports = {
  extends: [
    // add more generic rulesets here, such as:
    // 'eslint:recommended',
  rules: {
    // override/add rules settings here, such as:
    // 'json-schema-validator/no-invalid': 'error'

This plugin provides configs:

  • plugin:json-schema-validator/base ... Configuration to enable correct JSON, YAML and TOML parsing.
  • plugin:json-schema-validator/recommended ... Above, plus rule to validate with JSON Schema.

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.


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

💻 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": [


The rules with the following star are included in the configs.


Rule ID Description Fixable RECOMMENDED
json-schema-validator/no-invalid validate object with JSON Schema.

Advanced Usage


Use .eslintrc.* file to configure settings. See also:

Example .eslintrc.js:

module.exports = {
  settings: {
    "json-schema-validator": {
      http: {
        getModulePath: "",
        requestOptions: {},

Example of http

    return new Promise((resolve, reject) => {
        request.get(url, options, (error, _res, body) => {
            if (error) {


module.exports = {
  settings: {
    "json-schema-validator": {
      http: {
        getModulePath: require.resolve("./path/to/request-get.js"),
