# 2025 Best Practices for TPMJS Monorepo
This document outlines recommendations to make TPMJS a cutting-edge 2025 monorepo optimized for both human and agentic development (Claude Code, Cursor, etc.).
## High-Impact Additions
### 1. Agent-First Documentation
```
packages/docs/
├── architecture-decisions/ # ADRs in markdown
├── patterns/ # Common patterns with examples
├── schemas/ # JSON schemas for all data structures
└── examples/ # Working code examples per feature
```
**Why:** Claude Code and other agents work better with:
- Explicit decision documentation (ADRs)
- Pattern libraries showing "the right way"
- Machine-readable schemas
- Real working examples to reference
### 2. Automated Testing Pyramid
```bash
# Add to package.json scripts
"test:unit": "vitest" # ✅ Already have this
"test:integration": "vitest -c vitest.integration.config.ts" # Add
"test:e2e": "playwright test" # Add
"test:visual": "playwright test --grep @visual" # Add
"test:contracts": "pactum" # Add for API testing
```
**Packages to add:**
- `@playwright/test` - E2E testing
- `@playwright/experimental-ct-react` - Component testing
- `pactum` or `msw` integration tests (you have mocks setup)
- `chromatic` or `percy` - Visual regression
### 3. Type Coverage & Quality Gates
```json
// Add to root package.json
{
"scripts": {
"type-check": "tsc --noEmit",
"type-coverage": "type-coverage --at-least 95",
"find-deadcode": "knip",
"check-architecture": "depcruiser --validate"
}
}
```
**Add packages:**
- `type-coverage` - Ensure no implicit `any`
- `knip` - Find unused files/exports/dependencies
- `dependency-cruiser` - Enforce architecture rules
- `@total-typescript/ts-reset` - Better built-in types
### 4. Development Containers
```json
// .devcontainer/devcontainer.json
{
"name": "TPMJS Dev",
"dockerComposeFile": "docker-compose.yml",
"service": "dev",
"features": {
"ghcr.io/devcontainers/features/node:1": {},
"ghcr.io/devcontainers-contrib/features/pnpm:2": {}
},
"customizations": {
"vscode": {
"extensions": [
"biomejs.biome",
"bradlc.vscode-tailwindcss",
"lokalise.i18n-ally"
]
}
}
}
```
**Why:** Agents like Claude Code work better when environment is reproducible. This also helps human developers.
### 5. Code Generation & Scaffolding
```typescript
// packages/cli/ - Internal dev tool
import { scaffold } from '@tpmjs/cli';
// Commands:
pnpm gen:component ButtonGroup
pnpm gen:package @tpmjs/new-package
pnpm gen:app marketing-site
```
**Create:**
- `plop` or `hygen` templates
- Component scaffolding (with tests, stories, exports)
- Package scaffolding (with tsconfig, package.json, exports)
- Consistent file structure generation
**Why:** Agents can use these commands to create new code following your exact patterns.
### 6. Enhanced Strict Mode TypeScript
```json
// packages/tsconfig/base.json - Add these
{
"compilerOptions": {
"exactOptionalPropertyTypes": true,
"noUncheckedIndexedAccess": true,
"noPropertyAccessFromIndexSignature": true,
"allowUnusedLabels": false,
"allowUnreachableCode": false,
"noImplicitOverride": true
}
}
```
### 7. Bundle Analysis & Performance
```json
{
"scripts": {
"analyze": "turbo run build --filter=@tpmjs/web -- --analyze",
"lighthouse": "lhci autorun",
"bundle-size": "size-limit"
}
}
```
**Add:**
- `@next/bundle-analyzer`
- `@lhci/cli` - Lighthouse CI
- `size-limit` - Bundle size tracking in CI
### 8. Smart Dependency Management
```json
// .github/renovate.json
{
"extends": ["config:base"],
"packageRules": [
{
"matchPackagePatterns": ["*"],
"matchUpdateTypes": ["minor", "patch"],
"groupName": "all non-major dependencies",
"groupSlug": "all-minor-patch"
}
]
}
```
**Use:** Renovate or Dependabot with auto-merge for passing tests
### 9. API Documentation Generation
```bash
pnpm add -D -w typedoc typedoc-plugin-markdown
```
Auto-generate API docs from TSDoc comments that both humans and agents can read.
### 10. Schema-First Development
```typescript
// packages/schemas/ - Central schema definitions
export * from './tool-schema';
export * from './registry-api-schema';
export * from './event-schema';
// Use Zod for runtime + type generation
// Agents can read schemas to understand contracts
```
## Monorepo-Specific Improvements
### 11. Better Local Development
```typescript
// turbo.json
{
"pipeline": {
"dev": {
"cache": false,
"persistent": true,
"dependsOn": ["^build"]
},
"build": {
"dependsOn": ["^build"],
"outputs": ["dist/**", ".next/**"]
}
}
}
```
### 12. Workspace Protocols & Constraints
```yaml
# .pnpm-workspace.yaml
packages:
- 'apps/*'
- 'packages/*'
# Add constraints
pnpm-workspace-constraints:
dependencies:
'@tpmjs/ui': 'workspace:*'
'@tpmjs/utils': 'workspace:*'
```
## Recommended Final Structure
```

```
## Priority Order for Implementation
### Phase 1 (Foundation)
1. **Knip + type-coverage** - Catch issues early
2. **Code generation scripts** - Ensure consistency
3. **ADR documentation structure** - Decision tracking
### Phase 2 (Quality)
4. **E2E testing with Playwright** - Full user flow coverage
5. **Bundle analysis + performance budgets** - Keep app fast
6. **Stricter TypeScript settings** - Catch more bugs at compile time
### Phase 3 (DX)
7. **Dev containers** - Reproducible environments
8. **API documentation generation** - Auto-generated from code
9. **Renovate automation** - Keep dependencies fresh
## Benefits for Agent-Driven Development
1. **Explicit Patterns** - Agents can reference documented patterns instead of guessing
2. **Code Generation** - Consistent scaffolding commands agents can use
3. **Machine-Readable Schemas** - JSON schemas help agents understand data structures
4. **Quality Gates** - Automated checks catch agent mistakes early
5. **Working Examples** - Agents can copy-paste-adapt proven patterns
6. **Architecture Enforcement** - Dependency rules prevent agents from creating invalid imports
## Next Steps
Start with the highest ROI items:
1. Install Knip to find dead code
2. Set up code generation for components/packages
3. Create docs/patterns/ with common examples
4. Add stricter TypeScript compiler options
5. Set up Playwright for E2E testing
These changes will make the codebase more maintainable and significantly improve the experience of working with AI coding agents.

# Quality Gates Setup
This document describes the quality gate tools configured for the TPMJS monorepo.
## Installed Tools
### 1. TypeScript Type Checking
```bash
pnpm type-check
```
Runs `tsc --noEmit` across all packages to catch type errors.
### 2. Type Coverage
```bash
pnpm type-coverage
```
Uses `type-coverage` to ensure no implicit `any` types. Currently configured for 95% minimum coverage.
### 3. Dead Code Detection
```bash
pnpm find-deadcode
```
Uses `knip` to find:
- Unused files
- Unused dependencies
- Unused exports
- Unresolved imports
**Configuration:** `knip.json`
- Ignores test files, build artifacts (dist, .next, storybook-static)
- Workspace-aware for monorepo structure
### 4. Architecture Validation
```bash
pnpm check-architecture
```
Uses `dependency-cruiser` to enforce:
- No circular dependencies
- No unresolvable imports
- No deprecated dependencies
- **Custom rule:** Packages cannot import from apps (keeps packages reusable)
**Configuration:** `.dependency-cruiser.js`
- Simplified to standard rules only
- Excludes build artifacts automatically
- One custom rule: packages stay independent of apps
## Node.js Version
**Required:** Node.js 22+ (LTS)
The project uses `.nvmrc` to specify Node version:
```bash
nvm use
```
## Integration
### Pre-commit Hook (Optional)
Add to `.lefthook.yml`:
```yaml
pre-commit:
commands:
type-check:
run: pnpm type-check
deadcode:
run: pnpm find-deadcode
```
### CI Pipeline (Recommended)
Add to `.github/workflows/ci.yml`:
```yaml
- name: Type check
run: pnpm type-check
- name: Check architecture
run: pnpm check-architecture
- name: Find dead code
run: pnpm find-deadcode
```
## Current Status
### ✅ Type Check
All packages pass type checking.
### ✅ Architecture Check
**1 error, 14 warnings**
- **Error:** Missing export in `@tpmjs/ui/Tabs/types` (needs fix)
- **Warnings:** React listed in both dependencies and devDependencies (informational, not blocking)
### ⚠️ Dead Code Detection
**Minor issues found:**
- 1 unused file: `packages/config/eslint/react.js`
- 5 unused dependencies (can be cleaned up)
- 6 unused devDependencies (can be cleaned up)
These are informational and don't block development.
## Philosophy
The configuration follows a **practical, non-blocking** approach:
- Standard rules that prevent real problems
- No overly strict custom rules that make development difficult
- Warnings for things worth knowing about, errors for things that will break
- Build artifacts and config files are properly excluded
## Maintenance
Run these periodically to keep the codebase clean:
```bash
# Check everything
pnpm type-check && pnpm check-architecture && pnpm find-deadcode
# Or just the quick ones
pnpm type-check && pnpm find-deadcode
```
