# User Guide

# 💿 Installation

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

Requirements

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

# 📖 Usage

# Configuration

Use .eslintrc.* file to configure rules. See also: https://eslint.org/docs/user-guide/configuring (opens new window).

Example .eslintrc.js:

module.exports = {
  extends: [
    // add more generic rulesets here, such as:
    // 'eslint:recommended',
    'plugin:json-schema-validator/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 (opens new window) 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}"

# 💻 Editor Integrations

# Visual Studio Code

Use the dbaeumer.vscode-eslint (opens new window) 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"
    ]
}

# ⚡️ Advanced Usage

# Settings

Use .eslintrc.* file to configure settings. See also: https://eslint.org/docs/user-guide/configuring/configuration-files#adding-shared-settings (opens new window).

Example .eslintrc.js:

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

http ... Settings to resolve schema URLs.
- getModulePath ... Module path to GET the URL. The default implementation is ./src/utils/http-client/get-modules/http.ts (opens new window).
- requestOptions ... Options used in the module.

# Example of `http`

Example of using the request module for HTTP requests.

./path/to/request-get.js:

const request = require("request")

/**
 * GET Method using request module.
 */
module.exports = function get(url, options) {
    return new Promise((resolve, reject) => {
        request.get(url, options, (error, _res, body) => {
            if (error) {
                reject(error)
                return
            }
            resolve(body)
        })
    })
}

.eslintrc.js:

module.exports = {
  settings: {
    "json-schema-validator": {
      http: {
        getModulePath: require.resolve("./path/to/request-get.js"),
        requestOptions: {
          // Example of proxy settings.
          proxy: "http://my.proxy.com:8080/"
        },
      }
    }
  }
}
