@schafevormfenster/eslint-config

This package serves as the central Configuration Hub for ESLint across the @schafevormfenster monorepo. It orchestrates community standards (Next.js, TypeScript, Prettier) and integrates our internal custom rules.

Purpose

• Standardization: Ensures all projects (apps, libraries, tests) follow the same coding standards.
• Simplicity: Projects only need to install this one package instead of managing dozens of ESLint plugins and dependencies.
• Modularity: Provides composable configurations for different tech stacks (Next.js, Library, Playwright, etc.).

General Approach

This package exports Flat Config arrays that can be easily combined in your project's eslint.config.mjs. It wraps:

• Community Plugins: @typescript-eslint, @next/eslint-plugin-next, eslint-plugin-zod, eslint-plugin-playwright, etc.
• Internal Rules: @schafevormfenster/eslint-plugin (Logging, Architecture, etc.).

Usage

In your application's eslint.config.mjs:

import { defineConfig } from "eslint/config";
import svfNext from "@schafevormfenster/eslint-config/next";
import svfLogging from "@schafevormfenster/eslint-config/logging";
import svfPlaywright from "@schafevormfenster/eslint-config/playwright";

export default defineConfig([
  // 1. Base Stack (Next.js + TypeScript + React)
  ...svfNext,

  // 2. Domain Specific Rules
  ...svfLogging,

  // 3. Testing Overrides (only applies to test files)
  ...svfPlaywright,

  // 4. Local Overrides
  {
    rules: {
      "no-console": "warn"
    }
  }
]);
