@next-friday/eslint-plugin-friday

Next Friday-specific ESLint rules for structural constraints generic lint stacks do not encode.

• Rules target module boundaries, React component structure, JSX layout, props shape, and identifier quality.
• Rules expose focused behavior and documented options.
• The plugin is intentionally narrow: it adds Next Friday-specific semantics instead of duplicating maintained ecosystem rules.

Usage

Register the plugin in an ESLint Flat Config and enable the rules you need:

import friday from "@next-friday/eslint-plugin-friday";

export default [
  {
    plugins: {friday},
    rules: {
      "friday/no-lazy-identifiers": "error",
    },
  },
];

The package exports rule implementations and their documented options.
