uglier

Config files should be short

Without Uglier — sprawling JSON config

// .eslintrc.json — 200+ lines of this
{
  "extends": ["eslint:recommended", "prettier"],
  "plugins": ["@stylistic"],
  "rules": {
    "semi": ["error", "never"],
    "quotes": ["error", "double"],
    "indent": ["error", 2],
    "@stylistic/arrow-parens": ["error", "as-needed"],
    "@stylistic/brace-style": ["error", "1tbs"],
    "@stylistic/keyword-spacing": ["error", {
      "before": true, "after": false,
      "overrides": { "return": { "after": true } }
    }],
    // ... another 50 rules ...
  }
}
// And you still need prettier.config.js too.

With Uglier — composable, readable, done

// eslint.config.js — that's it, that's the whole file
import uglify from "@gesslar/uglier"

export default [
  ...uglify({
    with: [
      "lints-js",
      "lints-jsdoc",
      "node",
    ]
  })
]
