@eslint/js 8.56.0

The @eslint/js is a useful npm package that offers JavaScript-specific functionalities. Born out of the need to separate these functionalities from ESLint, @eslint/js provides two major configurations:

1. recommended - This configuration comprises rules that are highly recommended by the ESLint team. This is essentially a replacement for "eslint:recommended".
2. all - This configuration enables all ESLint rules and it serves as a replacement for "eslint:all".

These configurations grant you the ability to improve the quality of your JavaScript codebase and adhere to the best practices recommended by the experienced ESLint team.

The usage of @eslint/js is straightforward and well-documented. You start by installing it in your project using npm. The installation command is npm install @eslint/js -D. Once it is installed, you can use the configurations in your eslint.config.js file.

Here are a few examples of how you can use the @eslint/js configurations in your project:

To apply recommended rules to JavaScript files, you would write:

import js from "@eslint/js";

export default [
    {
        files: ["**/*.js"],
        rules: js.configs.recommended.rules
    }
]

You can also apply recommended rules with an override as follows:

import js from "@eslint/js";

export default [
    {
        files: ["**/*.js"],
        rules: {
            ...js.configs.recommended.rules,
            "no-unused-vars": "warn"
        }
    }
]

To apply all rules to your JavaScript files, the code would look something like this:

import js from "@eslint/js";

export default [
    {
        files: ["**/*.js"],
        rules: {
            ...js.configs.all.rules,
            "no-unused-vars": "warn"
        }
    }
]

Please note that you can change the rules according to your project’s requirements.

The documentation for the @eslint/js module is easily available on the ESLint website. The configurational aspects of ESLint can be found here, while a list of the rules it provides can be reviewed here.
