ESLint rules for WebdriverIO

You'll first need to install ESLint:

npm i eslint --save-dev

Next, install eslint-plugin-wdio:

npm install eslint-plugin-wdio --save-dev

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

This plugin export a recommended configuration that enforce good practices.

To enable this configuration use the extends property in your .eslintrc config file:

{
    "plugins": ["wdio"],
    "extends": [
        "eslint:recommended",
        "plugin:wdio/recommended"
    ]
}

If you are using the latest version of Eslint with the flat configuration, you can embed this plugin as follows:

// eslint.config.mjs
import { configs as wdioConfig } from "eslint-plugin-wdio";

export default [
    {
        extends: [
            wdioConfig['flat/recommended'],
            // ...
        ]
    }
];

See ESLint documentation for more information about extending configuration files.
