Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-jest-dom:

$ npm install eslint-plugin-jest-dom --save-dev

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

Usage

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

{
    "plugins": [
        "jest-dom"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "jest-dom/prefer-checked": "error",
        "jest-dom/prefer-enabled-disabled": "error",
        "jest-dom/prefer-required": "error"
    }
}
