And it happens to the best teams. - -Here's the hard truth: **Architecture erodes over time**. Without active enforcement, every shortcut, every "just this once" exception, every rushed feature slowly degrades your carefully designed system. - -### The Hidden Cost - -For a typical team of 10 developers, architectural problems cost: - -- **$100,000/year** in unnecessary refactorings -- **$50,000/year** in bug fixes from violations -- **$48,000/year** in extended onboarding time -- **$20,000/year** in code review overhead - -**Total: $248,000 annually** 💸 - -But what if you could **test your architecture** the same way you test your code? - -What if violations were caught **automatically in CI/CD** before they ever reached code review? - -What if your architecture rules were **executable, not just documentation** that nobody reads? - ---- - -## The Inspiration: ArchUnit for Java - -In the Java world, there's a brilliant library called [ArchUnit](https://www.archunit.org/) that solves this exact problem. Created by TNG Technology Consulting, ArchUnit allows Java developers to write unit tests for their architecture. - -Instead of documenting rules in a wiki that nobody reads, you write executable specifications: - -```java -// Java with ArchUnit -classes() - .that().resideInAPackage("..service..") - .should().onlyBeAccessed().byAnyPackage("..controller..", "..service..") -``` - -When someone violates this rule, **the test fails**.

And until now, **JavaScript and TypeScript developers didn't have anything like it**. - ---- - -## Enter ArchUnit-TS - -I'm excited to introduce **ArchUnit-TS**—the architecture testing framework for TypeScript and JavaScript, inspired by ArchUnit's philosophy but built specifically for the JavaScript ecosystem. - -**ArchUnit-TS** lets you specify and enforce architectural rules as executable code: - -```typescript -import { ArchRuleDefinition, createArchUnit } from 'archunit-ts'; - -const rule = ArchRuleDefinition.classes() - .that() - .resideInPackage('domain') - .should() - .notDependOnClassesThat() - .resideInPackage('infrastructure'); - -const violations = await archUnit.checkRule('./src', rule); -``` - -If a developer accidentally adds an infrastructure dependency to your domain layer, **the test fails**. Immediately. Automatically. - ---- - -## Why Architecture Testing Matters - -### 1. **Prevention is Better Than Cure** - -Catching architectural violations in CI/CD is infinitely cheaper than discovering them in production—or worse, during a major refactoring. - -```typescript -// ❌ This would fail the test immediately -// File: src/domain/entities/User.ts -import { PostgresClient } from '../infrastructure/database'; - -class User { - // Domain logic shouldn't depend on infrastructure! -} -``` - -Your CI/CD pipeline fails, saving you from merging problematic code. - -### 2. **Living Documentation** - -Architecture documents get outdated. Tests don't. - -```typescript -describe('Architecture: Clean Architecture Pattern', () => { - it('domain layer should be independent', async () => { - const rule = ArchRuleDefinition.classes() - .that() - .resideInPackage('domain') - .should() - .notDependOnClassesThat() - .resideInAnyPackage('infrastructure', 'presentation'); - - await expect(archUnit.checkRule('./src', rule)).resolves.toHaveLength(0); - }); -}); -``` - -This test **is** your documentation. And it's always accurate. - -### 3. **Onboarding Made Easy** - -New developers can understand your architecture by reading the tests: - -```typescript -describe('Architecture: MVC Pattern', () => { - it('controllers should only depend on services', async () => { - // Clear rule that teaches the pattern - }); - - it('models should not depend on anything', async () => { - // Prevents coupling at the data layer - }); - - it('services orchestrate business logic', async () => { - // Documents service layer responsibility - }); -}); -``` - -No need for a 50-page architecture document. The tests tell the story. - -### 4. **Refactoring with Confidence** - -Planning to split a monolith? Migrating to microservices?

Start Small - -Begin with a few critical rules: - -```typescript -// Start with the most important boundaries -describe('Critical Architecture Rules', () => { - it('domain should be independent', async () => { - // Your most important rule - }); -}); -``` - -### 2. Make Rules Specific - -Vague rules are hard to follow: - -```typescript -// ❌ Too vague -.should().beWellDesigned() - -// ✅ Specific and actionable -.should().notDependOnClassesThat().resideInPackage('infrastructure') -``` - -### 3. Document the "Why" - -```typescript -it('domain should not depend on infrastructure', async () => { - // WHY: Domain logic should be testable without database - // WHY: Enables switching infrastructure without changing domain - - const rule = ArchRuleDefinition.classes() - .that() - .resideInPackage('domain') - .should() - .notDependOnClassesThat() - .resideInPackage('infrastructure'); - - const violations = await archUnit.checkRule('./src', rule); - expect(violations).toHaveLength(0); -}); -``` - -### 4. Run in CI - -Make architecture tests part of your CI/CD pipeline: - -```typescript -// Fail the build on violations -const violations = await archUnit.checkRule('./src', rule); -ArchUnitTS.assertNoViolations(violations); // Throws if violations exist -``` - -### 5. Review Violations Together - -When a test fails, discuss it with the team: - -- Is the rule correct? -- Is the violation necessary? -- Should we update our architecture? - ---- - -## Comparison with Alternatives - -### vs. ESLint Import Rules - -| Feature | ArchUnit-TS | ESLint | -| --------------------- | ------------- | ----------------- | -| Layered architecture | ✅ Built-in | ⚠️ Complex config | -| Decorator checking | ✅ Yes | ❌ No | -| Naming conventions | ✅ Fluent API | ⚠️ Regex patterns | -| Architecture patterns | ✅ Pre-built | ❌ No | -| Learning curve | ✅ Low | ⚠️ Medium | - -**Use both!** ESLint for code style, ArchUnit-TS for architecture. - -### vs. dependency-cruiser - -| Feature | ArchUnit-TS | dependency-cruiser | -| -------------------------- | ---------------------- | ------------------ | -| Focus | Architecture patterns | Dependency graphs | -| Fluent API | ✅ Yes | ❌ Config-based | -| OOP patterns | ✅ Classes, decorators | ⚠️ Limited | -| Test framework integration | ✅ Native | ⚠️ Separate tool | - -**ArchUnit-TS** is higher-level and more architecture-focused. - ---- - -## Real Success Stories - -### Preventing a $50K Refactoring Disaster - -**Company:** Fintech startup with 15 developers -**Challenge:** Maintaining clean architecture during rapid growth -**Solution:** Implemented ArchUnit-TS architecture tests in CI/CD - -**Results:** - -- **47 violations caught** before reaching production in first month -- **1 critical violation** would have required a week of refactoring (estimated $8,000 in developer time) -- **Zero architectural drift incidents** since implementation -- **ROI: 500%** in first quarter (calculated savings vs. tool adoption cost) - -> "We caught 47 violations before they made it to production.

Patterns are validated to ensure they don't cause security issues: - -```typescript -import { CodeAnalyzer } from 'archunitnode'; - -const analyzer = new CodeAnalyzer(); - -// ✅ Safe patterns -await analyzer.analyze('./src', ['**/*.ts', '**/*.tsx', '!**/*.test.ts', '!**/node_modules/**']); - -// Patterns are processed by the 'glob' library which handles them safely -``` - -### Package Pattern Validation - -Package patterns in rules are validated to prevent injection attacks: - -```typescript -import { ArchRuleDefinition } from 'archunitnode'; - -// ✅ Safe package patterns -ArchRuleDefinition.classes() - .that() - .resideInPackage('services') // Exact match - .should() - .beAnnotatedWith('Service'); - -ArchRuleDefinition.classes() - .that() - .resideInAnyPackage('**/services') // Wildcard pattern - .should() - .beAnnotatedWith('Service'); - -// The pattern matching uses segment-based matching to prevent false positives -// "services" will NOT match "notservices" or "services-impl" -``` - -## Error Handling - -### Error Categorization - -The CodeAnalyzer categorizes errors into types for better handling: - -```typescript -import { CodeAnalyzer } from 'archunitnode'; - -const analyzer = new CodeAnalyzer(); -const result = await analyzer.analyzeWithErrors('./src'); - -// Group errors by type -const securityErrors = result.errors.filter((e) => e.errorType === 'security'); -const parseErrors = result.errors.filter((e) => e.errorType === 'parse'); -const ioErrors = result.errors.filter((e) => e.errorType === 'io'); -const unknownErrors = result.errors.filter((e) => e.errorType === 'unknown'); - -console.log(`Security violations: ${securityErrors.length}`); -console.log(`Parse errors: ${parseErrors.length}`); -console.log(`I/O errors: ${ioErrors.length}`); -``` - -### Error Types - -| Type | Description | Examples | -| ---------- | -------------------------- | ------------------------------ | -| `security` | Path traversal, null bytes | Path traversal detected | -| `parse` | Syntax errors | Unexpected token, Parse error | -| `io` | File system errors | ENOENT, EACCES, File not found | -| `unknown` | Unclassified errors | Other unexpected errors | - -### Graceful Degradation - -The `analyzeWithErrors` method continues analysis even when individual files fail: - -```typescript -const result = await analyzer.analyzeWithErrors('./src'); - -console.log(`Successfully analyzed: ${result.filesProcessed} files`); -console.log(`Skipped due to errors: ${result.filesSkipped} files`); -console.log(`Found classes: ${result.classes.size()}`); - -// You can still use the successfully analyzed classes -const classes = result.classes; -``` - -## Best Practices - -### 1. Always Use Absolute or Project-Relative Paths - -```typescript -import * as path from 'path'; - -// ✅ Good - Absolute path -const projectRoot = path.resolve(__dirname, '..'); -await analyzer.analyze(projectRoot); - -// ✅ Good - Relative to current directory -await analyzer.analyze('./src'); - -// ❌ Bad - User-provided paths without validation -const userPath = getUserInput(); -await analyzer.analyze(userPath); // Could contain ../../../ -``` - -### 2. Validate User Input - -If accepting paths from users, validate them first: - -```typescript -import * as path from 'path'; - -function analyzeUserProject(userProvidedPath: string) { - // Resolve and validate the path - const resolvedPath = path.resolve(userProvidedPath); - const projectRoot = path.resolve('.'); - - // Ensure path is within project boundaries - if (!resolvedPath.startsWith(projectRoot)) { - throw new Error('Invalid path: Outside project boundaries'); - } - - return analyzer.analyze(resolvedPath); -} -``` - -### 3. Handle Errors Appropriately - -```typescript -const result = await analyzer.analyzeWithErrors('./src'); - -// Check for security violations -const securityViolations = result.errors.filter((e) => e.errorType === 'security'); -if (securityViolations.length > 0) { - console.error('Security violations detected:'); - securityViolations.forEach((err) => { - console.error(` ${err.file}: ${err.error.message}`); - }); - process.exit(1); -} - -// Log other errors but continue -if (result.errors.length > 0) { - console.warn(`${result.errors.length} files could not be parsed`); -} -``` - -### 4. Use Glob Patterns to Exclude Sensitive Files - -```typescript -await analyzer.analyze('./src', [ - '**/*.ts', - '!**/*.test.ts', - '!**/*.spec.ts', - '!**/node_modules/**', - '!**/.env*', // Exclude environment files - '!**/secrets/**', // Exclude secrets directory - '!**/credentials.json', // Exclude credentials -]); -``` - -### 5. Enable Caching Safely - -Caching is safe to use as it validates file hashes: - -```typescript -// Cache is enabled by default with hash validation -const analyzer = new CodeAnalyzer({ enableCache: true }); - -// The cache checks SHA-256 hashes to detect file changes -// If a file changes, the cache is automatically invalidated -``` - -## Security Considerations for CI/CD - -When using ArchUnitNode in CI/CD pipelines: - -```typescript -// Example GitHub Actions / CI script -import { CodeAnalyzer } from 'archunitnode'; -import * as path from 'path'; - -async function analyzePullRequest() { - const analyzer = new CodeAnalyzer(); - - // Always use absolute paths in CI - const srcPath = path.resolve(process.env.GITHUB_WORKSPACE || '.', 'src'); - - const result = await analyzer.analyzeWithErrors(srcPath); - - // Fail the build if security errors are found - const securityErrors = result.errors.filter((e) => e.errorType === 'security'); - if (securityErrors.length > 0) { - console.error('Security violations found in code analysis'); - process.exit(1); - } - - return result.classes; -} -``` - -## Reporting Security Issues - -If you discover a security vulnerability in ArchUnitNode, please report it to: - -- **Email**: [Create an issue on GitHub](https://github.com/manjericao/ArchUnitNode/issues) -- **GitHub Security Advisory**: Use GitHub's security advisory feature - -Please do not disclose security vulnerabilities publicly until a fix is available. - -## Security Updates - -We take security seriously and will: - -1. Respond to security reports within 48 hours -2. Release security patches as soon as possible -3. Credit security researchers (unless they prefer to remain anonymous) -4.
