# Infrastructure
## Package Manager
**Use `bun`, never npm/yarn/pnpm.**
```bash
bun install # Install deps
bun add <pkg> # Add package
bun add -D <pkg> # Add dev dependency
bun run <script> # Run script
bunx <cmd> # Execute binary
```
## Monorepo Structure
```
comp/
├── apps/
│ ├── api/ # NestJS backend
│ ├── app/ # Next.js main app
│ └── portal/ # Next.js portal
├── packages/
│ ├── db/ # Prisma (@trycompai/db)
│ ├── ui/ # Legacy UI (@trycompai/ui); prefer @trycompai/design-system
│ └── ...
├── turbo.json
└── package.json
```
## Running Commands
```bash
# Multi-package (via turbo)
bun run build # Build all
bun run lint # Lint all
bun run typecheck # Type check all
bun run dev # Dev all
# Single package
bun run -F apps/app dev
bun run -F @trycompai/db prisma:generate
turbo build --filter=@trycompai/ui
```
## Importing Between Packages
```tsx
// ✅ Import from package name
import { Button } from '@trycompai/design-system';
import { prisma } from '@trycompai/db';
// ❌ Never relative paths across packages
import { Button } from '../../../packages/ui/src/button';
```
## Adding Dependencies
```bash
# To specific package
bun add axios -F apps/app
bun add -D vitest -F @trycompai/ui
# To root (dev tools only)
bun add -D -w prettier typescript
```
## After Code Changes
**Always run checks:**
```bash
bun run typecheck
bun run lint
```
Fix all errors before committing.
## Common TypeScript Fixes
- **Property does not exist**: Check interface definitions
- **Type mismatch**: Verify expected vs actual type
- **Empty interface extends**: Use `type X = SomeType` instead
## Common ESLint Fixes
- **Unused variables**: Remove or prefix with `_`
- **Any type**: Add proper typing
- **Empty object type**: Use `type` instead of `interface`
## Creating a New Package
```bash
mkdir packages/my-package
```
```json
// packages/my-package/package.json
{
"name": "@trycompai/my-package",
"version": "0.0.0",
"private": true,
"main": "./src/index.ts",
"scripts": {
"build": "tsup src/index.ts --format cjs,esm --dts",
"typecheck": "tsc --noEmit"
}
}
```
```json
// packages/my-package/tsconfig.json
{
"extends": "@trycompai/tsconfig/base.json",
"include": ["src"]
}
```
## Package Boundaries
**✅ Create packages for:**
- Code used by 2+ apps
- Self-contained, focused functionality
**❌ Don't create packages for:**
- Code only used in one app (colocate instead)
- App-specific business logic
