Next Friday Code Standards

One shared engineering contract for linting, formatting, and commit history across Next Friday JavaScript and TypeScript repositories.

Encode policy once. Keep repository behavior deterministic without rebuilding the same standards in every codebase.

Packages

Package	Purpose
@next-friday/eslint-config-friday	Strict ESLint Flat Config for JavaScript, TypeScript, React, Next.js, NestJS, Node.js, browser projects, tests, and common data formats.
@next-friday/prettier-config-friday	Shared Prettier configuration, including shell formatting.
@next-friday/commitlint-config-friday	Conventional Commit policy for commit messages.

Usage

ESLint

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

export default friday();

Browser and Node globals are available by default. Opt into framework policy explicitly:

export default friday({
  react: true,
  nextjs: true,
});

nextjs: true composes the bundled official Next.js Core Web Vitals policy. When react: true and nextjs: true are enabled together, Next.js convention files delegate module-structure semantics to Next.js while ordinary React modules keep the strict friday/component-module policy. nestjs: true adds the bundled NestJS typed recommended policy. React remains a separate explicit capability.

Prettier

{
  "prettier": "@next-friday/prettier-config-friday"
}

The package can also be referenced from a Prettier config file.

Commitlint

{
  "extends": ["@next-friday/commitlint-config-friday"]
}

The commit contract is <type>(<scope>): <subject>; scope is required and lowercase.
