eslint-plugin-json

Lint JSON files

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-json:

$ npm install eslint-plugin-json --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-json globally.

Add json to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "json"
    ]
}

You can run ESLint on individual JSON files or you can use the --ext flag to add JSON files to the list.

eslint --ext .json --ext .js
eslint example.json
