# Coding Style
|
|
|
|
## Immutability (CRITICAL)
|
|
|
|
ALWAYS create new objects, NEVER mutate:
|
|
|
|
```javascript
|
|
// WRONG: Mutation
|
|
function updateUser(user, name) {
|
|
user.name = name // MUTATION!
|
|
return user
|
|
}
|
|
|
|
// CORRECT: Immutability
|
|
function updateUser(user, name) {
|
|
return {
|
|
...user,
|
|
name
|
|
}
|
|
}
|
|
```
|
|
|
|
## File Organization
|
|
|
|
MANY SMALL FILES > FEW LARGE FILES:
|
|
- High cohesion, low coupling
|
|
- 200-400 lines typical, 800 max
|
|
- Extract utilities from large components
|
|
- Organize by feature/domain, not by type
|
|
|
|
## Error Handling
|
|
|
|
ALWAYS handle errors comprehensively:
|
|
|
|
```typescript
|
|
try {
|
|
const result = await riskyOperation()
|
|
return result
|
|
} catch (error) {
|
|
console.error('Operation failed:', error)
|
|
throw new Error('Detailed user-friendly message')
|
|
}
|
|
```
|
|
|
|
## Input Validation
|
|
|
|
ALWAYS validate user input:
|
|
|
|
```typescript
|
|
import { z } from 'zod'
|
|
|
|
const schema = z.object({
|
|
email: z.string().email(),
|
|
age: z.number().int().min(0).max(150)
|
|
})
|
|
|
|
const validated = schema.parse(input)
|
|
```
|
|
|
|
