Configuration Files & Environment Setup

This guide provides an overview of configuration management for LightSpeedWP projects, including tooling setup, build configuration, linting rules, and development environment initialization.

Overview

Configuration files define how LightSpeedWP projects behave across development, testing, and production environments. This document serves as a high-level guide to configuration management strategies and patterns.

For detailed configuration file documentation, see Configuration Files Index.

Configuration Categories

Build & Compilation

Configuration files that control how code is built and compiled:

• babel.config.md — Babel transpilation configuration
• webpack.config.md — Module bundling (if applicable)
• tsconfig.json — TypeScript compilation settings

Linting & Code Quality

Tools that enforce code standards:

• eslint.config.md — JavaScript/TypeScript linting rules
• prettier.config.md — Code formatting standards
• stylelint.config.md — CSS/SCSS linting (if applicable)
• yamllint.config.md — YAML validation

Testing & Coverage

Configuration for automated testing:

• jest.config.md — JavaScript testing framework
• playwright.config.md — End-to-end browser testing

Environment & Runtime

Files that configure runtime behavior:

• .editorconfig — Editor standardization
• .env.example — Environment variable templates
• .npmrc / .yarnrc — Package manager settings

Package & Dependencies

Dependency and package configuration:

• package.json — NPM package definition and scripts
• package-lock.json — Locked dependency versions
• composer.json — PHP dependency management (if applicable)

Validation & Standards

Configuration for schema and compliance:

• frontmatter.schema.json — Documentation frontmatter validation
• .prettier.config.js — Formatting consistency

Environment Setup

Local Development

1. Install Dependencies

   npm install    # JavaScript/Node.js dependencies
   composer install  # PHP dependencies (if applicable)

2. Configure Environment Variables

   cp .env.example .env.local
   # Edit .env.local with local settings

3. Initialize Pre-commit Hooks

   npm run prepare  # Install Husky pre-commit hooks

Build & Compilation

npm run build     # Production build
npm run dev       # Development build with watch mode
npm run lint      # Run linters (ESLint, Prettier, etc.)

Testing

npm test          # Run all tests
npm run test:e2e  # Run end-to-end tests
npm run coverage  # Generate coverage reports

Common Configuration Tasks

Adding a New Environment Variable

1. Add to .env.example with explanation
2. Document in CONFIGURATIONS.md
3. Update deployment/CI configuration
4. Test in all environments

Updating Linting Rules

1. Modify rule in .eslintrc.json or eslint.config.cjs
2. Run linter across codebase: npm run lint:fix
3. Document change in PR description
4. Update this guide if needed

Changing Build Output

1. Update build config (tsconfig.json, babel.config.js, etc.)
2. Test build locally: npm run build
3. Verify output in build artifacts
4. Update CI configuration if needed

Quick Reference

Config File	Purpose	Status
eslint.config.cjs	JS/TS linting	Active
prettier.config.js	Code formatting	Active
.editorconfig	Editor settings	Active
jest.config.js	Testing	Active
package.json	Dependencies	Active
tsconfig.json	TypeScript	Active
playwright.config.js	E2E testing	Active

Configuration Standards

Naming Conventions

• Use lowercase for filenames: .eslintrc.json, prettier.config.js
• Use camelCase for configuration keys: ignorePattern, arrowParens
• Use kebab-case for CLI flags: --no-cache, --max-workers

File Format

• Prefer JSON for static configuration (validate against schema)
• Use JavaScript files for dynamic configuration logic
• YAML for Docker and CI/CD configuration
• Comments in configuration files (where supported)

Documentation

• Every configuration file should have a .md guide in docs/config/
• Include purpose, structure, and common customizations
• Provide examples and troubleshooting tips

Troubleshooting

Issue: Configuration changes not taking effect

• Clear build cache: npm run clean or rm -rf dist/
• Verify file syntax: Run config validation
• Check for duplicate configuration files
• Restart development server

Issue: Linting failures after update

• Review linting rule changes in .eslintrc.json
• Run fixer: npm run lint:fix
• Check for conflicting rules (ESLint ↔ Prettier)

Issue: Environment variables not available

• Verify .env.local contains required variables
• Check environment variable loading in build config
• Ensure variables are exported in shell environment

Next Steps

• Review Linting Standards for code quality configuration
• See Configuration Files Index for detailed file documentation
• Check Testing Guide for test configuration details
