@sylphlab/eslint-config-sylph-strict v0.2.0

@sylphlab/eslint-config-sylph-strict

This package provides the Strict ESLint Flat Configuration for SylphLab TypeScript projects.

It extends the standard @sylphlab/eslint-config-sylph configuration and adds stricter rules suitable for mature projects or pre-release validation.

Philosophy

• Extends Standard: Builds upon the base @sylphlab/eslint-config-sylph configuration.
• Maximum Strictness: Re-enforces rules relaxed in the standard config (e.g., no-explicit-any, abbreviations) as errors.
• Low Limits: Enforces low limits for complexity, file/function length, nesting depth, and parameters as errors.

• Functional Programming: Re-introduces strict functional programming rules (immutability, no-throw) via eslint-plugin-functional.

Use this configuration when the highest level of code quality, consistency, and adherence to strict patterns is required. For general development, the standard @sylphlab/eslint-config-sylph configuration is recommended.

Installation

1. Ensure Standard Config is Installed: Follow the installation steps for @sylphlab/eslint-config-sylph first, including installing ESLint, TypeScript, and all its peer dependencies (using install-peerdeps is recommended).
2. Install This Package:

   # Using pnpm (recommended)
   pnpm add -D @sylphlab/eslint-config-sylph-strict

3. Install Additional Peer Dependencies: This package requires eslint-plugin-functional.

   pnpm add -D eslint-plugin-functional

   (Note: Other peers like eslint, typescript, typescript-eslint should already be installed via the standard config setup).

Usage (eslint.config.js or eslint.config.ts)

Import the configuration array from this package instead of the standard one.

// eslint.config.js
import { sylphStrict } from '@sylphlab/eslint-config-sylph-strict';

export default [
  ...sylphStrict,
  // Add any project-specific overrides here, if absolutely necessary
  {
    // Example: Further restrict a rule if needed
    // rules: { 'max-params': ['error', 3] }
  },
];

Important: Ensure you have a correctly configured tsconfig.json that includes all files intended for linting. This strict configuration relies heavily on type information.
