[Testing Strategy](#testing-strategy) + +--- + +## Overview + +### Problem Statement + +Currently, Guardian uses hardcoded rules and layer paths. This prevents: +- ❌ Customization for different project structures +- ❌ Disabling specific rules +- ❌ Per-file or per-directory overrides +- ❌ Team-specific configurations +- ❌ Framework-specific presets (NestJS, Express, etc.) + +**Without configuration support, Guardian cannot scale to enterprise adoption.** + +### Solution + +Add comprehensive configuration system with: +- ✅ Multiple file format support +- ✅ Zero-config presets +- ✅ Rule-level customization +- ✅ Custom layer paths +- ✅ Ignore patterns +- ✅ CLI overrides + +### Success Criteria + +- [ ] Support 5+ configuration file formats +- [ ] Provide 4+ built-in presets +- [ ] Enable/disable any rule via config +- [ ] Custom layer path mapping +- [ ] Per-file/directory ignore patterns +- [ ] CLI can override any config option +- [ ] 100% backward compatible (default config) +- [ ] Complete documentation with examples +- [ ] 95%+ test coverage + +--- + +## Goals & Non-Goals + +### Goals + +✅ **Configuration Discovery** +- Support multiple file formats +- Auto-discover config in project root +- Clear precedence order + +✅ **Zero-Config Experience** +- Works without config (sensible defaults) +- Presets for common architectures + +✅ **Flexibility** +- Enable/disable any rule +- Custom severity levels +- Per-file ignores + +✅ **Developer Experience** +- `guardian init` command +- Config validation +- Helpful error messages + +### Non-Goals + +❌ **Remote Configuration** +- No fetching config from URLs (v1.0+ maybe) + +❌ **Shareable Config Packages** +- No `@company/guardian-config` packages (v0.7+ maybe) + +❌ **GUI Config Editor** +- CLI/text-based only (v1.0+ maybe) + +--- + +## Configuration File Format + +### Supported File Formats + +Guardian will discover configuration in this order: + +1. `guardian.config.js` (ES modules) - **Recommended** +2. `guardian.config.cjs` (CommonJS) +3. `guardian.config.mjs` (ES modules, explicit) +4. `.guardianrc` (JSON) +5. `.guardianrc.json` (JSON,

& Answers + +### Q: Will this be a breaking change? + +**A:** No, v0.6.0 is 100% backward compatible. If no config file exists, Guardian uses the same default behavior as v0.5.1. + +### Q: Can I migrate incrementally? + +**A:** Yes! Start with `preset: 'clean-architecture'` and customize one rule at a time. + +### Q: Will presets be updateable? + +**A:** Presets are versioned with Guardian. When you update Guardian, presets update too. You can pin to a specific preset version in future versions. + +### Q: Can I use TypeScript for config? + +**A:** Yes, in v0.7.0+ we'll add `guardian.config.ts` support.
