eslint-config

An opinionated, but sane ESLint shareable config that I used in my projects ✔

Install

npm install -D @hazmi35/eslint-config # npm
pnpm add -D @hazmi35/eslint-config # pnpm
yarn add -D @hazmi35/eslint-config # yarn

This package has the required dependency installed automatically by peer dependencies by default on npm v7+, pnpm, or yarn. Install them manually if not.

Usage

This package requires ESLint Flat Configuration.

Available configurations:

• common - Common JavaScript rules.
• typescript - For usage with TypeScript
• stylistic - For code styling with ESLint Stylistic. (Exclusive with Prettier)
• prettier - For code styling with Prettier. (Exclusive with ESLint Stylistic)
• browser - For usage within a browser environment (DOM and Web APIs).
• node - For usage within a Node.js or Bun environment.
• edge - For usage within an edge/serverless environment. For example Cloudflare Workers.
• modules - For usage with ES Modules.
• ignores - To enable global ignores for ESLint. Needed for ESLint to ignore files that shouldn't be linted.

Configuration

Create an eslint.config.js file in the root of your project and add the following code:

import { common, modules, node, stylistic, ignores } from "@hazmi35/eslint-config";

export default [...common, ...modules, ...node, ...stylistic, ...ignores];

module.exports = (async () => {
    const { common, node, stylistic, ignores } = await import("@hazmi35/eslint-config");

    return [...common, ...node, ...stylistic, ...ignores];
})();

import { common, modules, node, stylistic, typescript, ignores } from "@hazmi35/eslint-config";

export default [...common, ...modules, ...node, ...stylistic, ...typescript, ...ignores];

import { common, modules, node, prettier, ignores } from "@hazmi35/eslint-config";

// Prettier must not be used with stylistic config, because it will conflict with each other.
export default [...common, ...modules, ...node, ...prettier, ...ignores];

Extending rules using the extend function is recommended.

import { common, extend, modules, node, stylistic, typescript, ignores } from "./index.js";

export default [...common, ...modules, ...node, ...stylistic, ...ignores, ...extend(typescript, [
    {
        rule: "typescript/no-unnecessary-condition",
        option: [
            "warn",
            {
                allowConstantLoopConditions: false
            }
        ]
        // or
        option: ["off"]
    }
])];
