Install

npm install -D @tucchi-/eslint-config eslint typescript typescript-eslint @eslint/js eslint-plugin-unicorn globals

Usage

Create eslint.config.js:

import config from "@tucchi-/eslint-config";

export default config();

With Options

import config from "@tucchi-/eslint-config";

export default config({
  files: ["src/**/*.ts"],
  ignores: ["dist/", "coverage/"],
  maxDepth: 2, // Allow one level of nesting if needed
  rules: {
    "unicorn/no-null": "off", // Override specific rules
  },
});

With Bun

Add Bun global:

import config from "@tucchi-/eslint-config";

export default [
  ...config(),
  {
    languageOptions: {
      globals: { Bun: "readonly" },
    },
  },
];

What's Enforced

• null → undefined
• Full variable names (msg → message, cb → callback)
• node: protocol for Node.js imports
• Top-level await preferred
• No nesting allowed (early return pattern enforced)
• No any type
• No non-null assertions (!)
• type only (no interface)
• Arrow functions only (no function)
