# Comprehensive Code Review - January 2025
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The WorkForce Pro codebase has been thoroughly reviewed across 74 iterations. This document outlines additional improvements, best practices, and optimizations beyond the critical fixes already applied.
|
||||
|
||||
## ✅ Previously Fixed Issues (Confirmed Working)
|
||||
|
||||
1. **Stale Closure Bugs** - Fixed in `use-app-actions.ts`
|
||||
2. **Express Admin Login** - Fixed in `LoginScreen.tsx`
|
||||
3. **Avatar URLs** - Added to all users in `logins.json`
|
||||
4. **Error Boundaries** - Added to `ViewRouter.tsx`
|
||||
5. **Metrics Memoization** - Optimized in `use-app-data.ts`
|
||||
|
||||
## 🔍 New Findings & Recommendations
|
||||
|
||||
### 1. Performance Optimizations
|
||||
|
||||
#### 1.1 Translation Loading
|
||||
**Current State**: Translations are loaded dynamically on locale change, but no caching strategy.
|
||||
|
||||
**Issue**: Repeated locale switches reload the same JSON files.
|
||||
|
||||
**Recommendation**: Implement a translation cache.
|
||||
|
||||
**Priority**: Medium
|
||||
|
||||
#### 1.2 Redux State Persistence
|
||||
**Current State**: Redux state resets on page refresh.
|
||||
|
||||
**Issue**: Users lose their view, search query, and UI state on refresh.
|
||||
|
||||
**Recommendation**: Persist UI state to localStorage/KV.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
#### 1.3 Large List Rendering
|
||||
**Current State**: All views render full lists without virtualization.
|
||||
|
||||
**Issue**: Performance degrades with >100 items.
|
||||
|
||||
**Recommendation**: Implement virtual scrolling for large datasets.
|
||||
|
||||
**Priority**: Medium
|
||||
|
||||
### 2. Code Quality Improvements
|
||||
|
||||
#### 2.1 TypeScript Strictness
|
||||
**Finding**: Some files use `any` types unnecessarily.
|
||||
|
||||
**Examples**:
|
||||
- `use-app-actions.ts` line 21: `addNotification: (notification: any)`
|
||||
- Various component props using `any`
|
||||
|
||||
**Recommendation**: Replace with proper typed interfaces.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
#### 2.2 Error Handling Consistency
|
||||
**Finding**: Inconsistent error handling patterns across the app.
|
||||
|
||||
**Examples**:
|
||||
- Some components use try-catch with toast
|
||||
- Others just log to console
|
||||
- Some don't handle errors at all
|
||||
|
||||
**Recommendation**: Create a standardized error handling utility.
|
||||
|
||||
**Priority**: Medium
|
||||
|
||||
#### 2.3 Magic Numbers and Strings
|
||||
**Finding**: Hard-coded values throughout the codebase.
|
||||
|
||||
**Examples**:
|
||||
```typescript
|
||||
// In LoginScreen.tsx
|
||||
setTimeout(() => { ... }, 800)
|
||||
|
||||
// In various files
|
||||
padStart(5, '0')
|
||||
Date.now() + 30 * 24 * 60 * 60 * 1000
|
||||
```
|
||||
|
||||
**Recommendation**: Extract to named constants.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
### 3. Security Enhancements
|
||||
|
||||
#### 3.1 Password Storage in JSON
|
||||
**Current State**: Passwords stored in plain text in `logins.json`.
|
||||
|
||||
**Issue**: Not suitable for production (though acceptable for demo).
|
||||
|
||||
**Status**: ⚠️ Known limitation - Document clearly
|
||||
|
||||
**Action**: Add prominent warning in documentation
|
||||
|
||||
#### 3.2 Permission Checks
|
||||
**Current State**: `PermissionGate` component exists but not used consistently.
|
||||
|
||||
**Finding**: Some sensitive operations lack permission checks.
|
||||
|
||||
**Recommendation**: Audit all sensitive operations and add gates.
|
||||
|
||||
**Priority**: High
|
||||
|
||||
#### 3.3 Input Sanitization
|
||||
**Finding**: User inputs are not consistently sanitized.
|
||||
|
||||
**Risk**: XSS vulnerabilities in search queries and text fields.
|
||||
|
||||
**Recommendation**: Add input sanitization utility.
|
||||
|
||||
**Priority**: High
|
||||
|
||||
### 4. Accessibility Issues
|
||||
|
||||
#### 4.1 Keyboard Navigation
|
||||
**Finding**: Some interactive elements lack keyboard support.
|
||||
|
||||
**Examples**:
|
||||
- Custom dropdowns may trap focus
|
||||
- Modal dialogs need better focus management
|
||||
- Some buttons lack proper ARIA labels
|
||||
|
||||
**Recommendation**: Complete accessibility audit.
|
||||
|
||||
**Priority**: Medium
|
||||
|
||||
#### 4.2 Screen Reader Support
|
||||
**Finding**: Dynamic content updates don't announce to screen readers.
|
||||
|
||||
**Examples**:
|
||||
- Toast notifications
|
||||
- Loading states
|
||||
- Data table updates
|
||||
|
||||
**Recommendation**: Add ARIA live regions.
|
||||
|
||||
**Priority**: Medium
|
||||
|
||||
#### 4.3 Color Contrast
|
||||
**Finding**: Some color combinations may not meet WCAG AA standards.
|
||||
|
||||
**Status**: Needs verification with contrast checker tool.
|
||||
|
||||
**Recommendation**: Audit all color pairings.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
### 5. State Management Issues
|
||||
|
||||
#### 5.1 Redundant State
|
||||
**Finding**: Some data is duplicated between Redux and local component state.
|
||||
|
||||
**Example**: Search queries stored in both Redux and some component states.
|
||||
|
||||
**Recommendation**: Single source of truth for each piece of data.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
#### 5.2 Derived State
|
||||
**Finding**: Some derived data is stored instead of computed.
|
||||
|
||||
**Example**: Dashboard metrics could be selectors instead of stored state.
|
||||
|
||||
**Recommendation**: Use Redux selectors with memoization.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
#### 5.3 State Hydration Race Conditions
|
||||
**Finding**: Redux initializes before KV data loads.
|
||||
|
||||
**Issue**: `use-locale-init.ts` has race condition potential.
|
||||
|
||||
**Status**: Currently mitigated with `useRef` flag.
|
||||
|
||||
**Recommendation**: Monitor for edge cases.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
### 6. Bundle Size & Loading
|
||||
|
||||
#### 6.1 Lazy Loading Coverage
|
||||
**Current State**: Views are lazy loaded ✅
|
||||
|
||||
**Finding**: Some large dependencies are not code-split.
|
||||
|
||||
**Examples**:
|
||||
- `recharts` (large charting library)
|
||||
- `three` (3D library - if used)
|
||||
- Icon libraries
|
||||
|
||||
**Recommendation**: Dynamic imports for heavy libraries.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
#### 6.2 Unused Dependencies
|
||||
**Status**: Need audit of package.json
|
||||
|
||||
**Action**: Run `npm prune` and verify all dependencies are used.
|
||||
|
||||
**Priority**: Low
|
||||
|
||||
### 7. Testing Gaps

## 🚀 Quick Wins (Can Implement Now)
|
||||
|
||||
### 1. Constants File
|
||||
Create a constants file for magic numbers:
|
||||
|
||||
```typescript
|
||||
// src/lib/constants.ts
|
||||
export const TIMEOUTS = {
|
||||
LOGIN_DELAY: 800,
|
||||
TOAST_DURATION: 3000,
|
||||
POLLING_INTERVAL: 30000,
|
||||
} as const
|
||||
|
||||
export const FORMATS = {
|
||||
DATE: 'yyyy-MM-dd',
|
||||
DATETIME: 'yyyy-MM-dd HH:mm:ss',
|
||||
TIME: 'HH:mm',
|
||||
} as const
|
||||
|
||||
export const DURATIONS = {
|
||||
INVOICE_DUE_DAYS: 30,
|
||||
SESSION_TIMEOUT_MINUTES: 60,
|
||||
AUTO_SAVE_DELAY_MS: 2000,
|
||||
} as const
|
||||
|
||||
export const LIMITS = {
|
||||
MAX_FILE_SIZE_MB: 10,
|
||||
MAX_BATCH_SIZE: 100,
|
||||
PAGE_SIZE: 20,
|
||||
} as const
|
||||
```
|
||||
|
||||
### 2. Error Handler Utility
|
||||
```typescript
|
||||
// src/lib/error-handler.ts
|
||||
import { toast } from 'sonner'
|
||||
|
||||
export function handleError(error: unknown, context?: string) {
|
||||
const message = error instanceof Error ? error.message : 'An unexpected error occurred'
|
||||
|
||||
console.error(`[${context || 'Error'}]:`, error)
|
||||
|
||||
toast.error(context ? `${context}: ${message}` : message)
|
||||
}
|
||||
|
||||
export function handleAsyncError<T>(
|
||||
promise: Promise<T>,
|
||||
context?: string
|
||||
): Promise<T | null> {
|
||||
return promise.catch((error) => {
|
||||
handleError(error, context)
|
||||
return null
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Input Sanitizer
|
||||
```typescript
|
||||
// src/lib/sanitize.ts
|
||||
export function sanitizeHTML(input: string): string {
|
||||
const element = document.createElement('div')
|
||||
element.textContent = input
|
||||
return element.innerHTML
|
||||
}
|
||||
|
||||
export function sanitizeSearchQuery(query: string): string {
|
||||
return query
|
||||
.trim()
|
||||
.replace(/[<>]/g, '')
|
||||
.slice(0, 200)
|
||||
}
|
||||
|
||||
export function sanitizeFilename(filename: string): string {
|
||||
return filename
|
||||
.replace(/[^a-zA-Z0-9._-]/g, '_')
|
||||
.slice(0, 255)
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Type Guard Utilities
|
||||
```typescript
|
||||
// src/lib/type-guards.ts
|
||||
export function isNotNull<T>(value: T | null | undefined): value is T {
|
||||
return value !== null && value !== undefined
|
||||
}
|
||||
|
||||
export function isValidDate(date: unknown): date is Date {
|
||||
return date instanceof Date && !isNaN(date.getTime())
|
||||
}
|
||||
|
||||
export function isValidTimesheet(obj: unknown): obj is Timesheet {
|
||||
// Add runtime validation
|
||||
return (
|
||||
typeof obj === 'object' &&
|
||||
obj !== null &&
|
||||
'id' in obj &&
|
||||
'workerName' in obj &&
|
||||
'hours' in obj
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
**Purpose**: Eliminate magic numbers and strings throughout the codebase
|
||||
|
||||
**Features**:
|
||||
- `TIMEOUTS`: Login delay, polling intervals, debounce delays
|
||||
- `FORMATS`: Date/time display formats
|
||||
- `DURATIONS`: Invoice due days, session timeout
|
||||
- `LIMITS`: File sizes, batch sizes, password requirements
|
||||
- `BREAKPOINTS`: Responsive design breakpoints
|
||||
- `STATUS_COLORS`: Consistent status color mapping
|
||||
- `ERROR_MESSAGES`: Standard error message strings
|
||||
|
||||
**Example Usage**:
|
||||
```typescript
|
||||
import { TIMEOUTS, LIMITS } from '@/lib/constants'
|
||||
|
||||
setTimeout(refresh, TIMEOUTS.POLLING_INTERVAL) // Instead of 30000
|
||||
if (file.size > LIMITS.MAX_FILE_SIZE_BYTES) { /* error */ }
|
||||
```
|
||||
|
||||
### 7. ✅ Created Error Handler Utility
|
||||
**File**: `/src/lib/error-handler.ts`
|
||||
|
||||
**Purpose**: Standardized error handling across the application
|
||||
|
||||
**Features**:
|
||||
- Custom error classes: `ValidationError`, `AuthenticationError`, `NetworkError`
|
||||
- `handleError()`: Centralized error logging and user notifications
|
||||
- `handleAsyncError()`: Async wrapper with automatic error handling
|
||||
- `withErrorHandler()`: Higher-order function wrapper
|
||||
- `logError()`: Persistent error logging to KV store
|
||||
|
||||
**Example Usage**:
|
||||
```typescript
|
||||
import { handleError, handleAsyncError } from '@/lib/error-handler'
|
||||
|
||||
try {
|
||||
await riskyOperation()
|
||||
} catch (error) {
|
||||
handleError(error, 'Operation Name')
|
||||
}
|
||||
|
||||
const data = await handleAsyncError(fetchData(), 'Fetch Data')
|
||||
if (!data) { /* handled gracefully */ }
|
||||
```
|
||||
|
||||
### 8. ✅ Created Input Sanitization Library

||||
- `sanitizeHTML()`: Strip dangerous HTML tags
|
||||
- `sanitizeSearchQuery()`: Clean search inputs
|
||||
- `sanitizeEmail()`: Normalize email addresses
|
||||
- `sanitizeURL()`: Validate and clean URLs
|
||||
- `sanitizeFilename()`: Safe filename generation
|
||||
- `sanitizeNumericInput()`: Parse and validate numbers
|
||||
- Plus 10+ more specialized sanitizers
|
||||
|
||||
**Example Usage**:
|
||||
```typescript
|
||||
import { sanitizeEmail, sanitizeSearchQuery } from '@/lib/sanitize'
|
||||
|
||||
const email = sanitizeEmail(userInput) // Lowercase, trim, limit length
|
||||
const query = sanitizeSearchQuery(searchTerm) // Remove dangerous chars
|
||||
```
|
||||
|
||||
### 9. ✅ Created Type Guard Library
|
||||
**File**: `/src/lib/type-guards.ts`
|
||||
|
||||
**Purpose**: Runtime type validation for improved TypeScript safety
|
||||
|
||||
**Features**:
|
||||
- Basic guards: `isNotNull`, `isDefined`, `isValidDate`
|
||||
- Validation guards: `isValidEmail`, `isValidPhoneNumber`, `isValidURL`
|
||||
- Entity guards: `isValidTimesheet`, `isValidInvoice`, `isValidWorker`
|
||||
- Collection guards: `isArrayOf`, `isRecordOf`
|
||||
- Property guards: `hasProperty`, `hasProperties`
|
||||
|
||||
**Example Usage**:
|
||||
```typescript
|
||||
import { isValidTimesheet, isArrayOf } from '@/lib/type-guards'
|
||||
|
||||
if (isValidTimesheet(data)) {
|
||||
// TypeScript knows data is Timesheet
|
||||
console.log(data.workerName)
|
||||
}
|
||||
|
||||
if (isArrayOf(items, isValidTimesheet)) {
|
||||
// TypeScript knows items is Timesheet[]
|
||||
}
|
||||
```
|
||||
|
||||
### 10. ✅ Created Validation Library
|
||||
**File**: `/src/lib/validation.ts`
|
||||
|
||||
**Purpose**: Comprehensive form validation with detailed error messages
|
||||
|
||||
**Features**:
|
||||
- Field validators: email, password, username, phone, URL
|
||||
- Numeric validators: range checking, integer validation
|
||||
- Date validators: date format, date range validation
|
||||
- File validators: size and type checking
|
||||
- Form validator: batch validation with error collection
|
||||
- Validation result type: `{ isValid: boolean, errors: string[] }`
|
||||
|
||||
**Example Usage**:
|
||||
```typescript
|
||||
import { validateEmail, validateFormData } from '@/lib/validation'
|
||||
|
||||
const result = validateEmail(email)
|
||||
if (!result.isValid) {
|
||||
console.log(result.errors) // ['Email format is invalid']
|
||||
}
|
||||
|
||||
const { isValid, errors } = validateFormData(formData, {
|
||||
email: validateEmail,
|
||||
password: validatePassword,
|
||||
age: (v) => validateNumber(v, 18, 120, 'Age'),
|
||||
})
|
||||
```
|
||||
|
||||
### 11. ✅ Enhanced Utils Export
|
||||
**File**: `/src/lib/utils.ts`
|
||||
|
||||
**Update**: Now exports all utility modules for convenient imports
|
||||
|
||||
```typescript
|
||||
// Before: Multiple imports
|
||||
import { cn } from '@/lib/utils'
|
||||
import { TIMEOUTS } from '@/lib/constants'
|
||||
import { handleError } from '@/lib/error-handler'
|
||||
|
||||
// After: Single import
|
||||
import { cn, TIMEOUTS, handleError } from '@/lib/utils'
|
||||
```
|
||||
|
||||
### 12. ✅ Updated LoginScreen with New Utilities
|
||||
**File**: `/src/components/LoginScreen.tsx`
|
||||
|
||||
**Improvements**:
|
||||
- Uses `TIMEOUTS.LOGIN_DELAY` instead of magic number 800
|
||||
- Uses `sanitizeEmail()` before processing
|
||||
- Uses `isValidEmail()` for validation
|
||||
- Uses `handleError()` for error handling
|
||||

import { sanitizeNumericInput, sanitizeInteger } from '@/lib/sanitize'
|
||||
|
||||
const num = sanitizeNumericInput(value) // Returns number or null
|
||||
const int = sanitizeInteger(value, 0, 100) // Clamps to min/max
|
||||
```
|
||||
|
||||
**Filenames & Special Fields**
|
||||
```typescript
|
||||
import {
|
||||
sanitizeFilename,
|
||||
sanitizePhoneNumber,
|
||||
sanitizeUsername,
|
||||
sanitizePostalCode
|
||||
} from '@/lib/sanitize'
|
||||
|
||||
const filename = sanitizeFilename(upload.name)
|
||||
const phone = sanitizePhoneNumber(phoneInput)
|
||||
const username = sanitizeUsername(userInput)
|
||||
```
|
||||
|
||||
**Data Export**
|
||||
```typescript
|
||||
import { sanitizeCSVValue, truncateString } from '@/lib/sanitize'
|
||||
|
||||
const csvSafe = sanitizeCSVValue(cellValue)
|
||||
const short = truncateString(longText, 100, '...')
|
||||
```
|
||||
|
||||
### 5. `type-guards.ts`
|
||||
|
||||
Runtime type checking and validation guards.
|
||||
|
||||
#### Basic Guards:
|
||||
|
||||
```typescript
|
||||
import { isNotNull, isDefined, isValidDate } from '@/lib/type-guards'
|
||||
|
||||
if (isNotNull(value)) {
|
||||
// TypeScript knows value is not null/undefined
|
||||
}
|
||||
|
||||
if (isValidDate(dateInput)) {
|
||||
// TypeScript knows it's a Date
|
||||
}
|
||||
```
|
||||
|
||||
#### Validation Guards:
|
||||
|
||||
```typescript
|
||||
import {
|
||||
isValidEmail,
|
||||
isValidPhoneNumber,
|
||||
isValidURL,
|
||||
isPositiveNumber,
|
||||
isValidCurrency
|
||||
} from '@/lib/type-guards'
|
||||
|
||||
if (isValidEmail(email)) {
|
||||
// Email format is correct
|
||||
}
|
||||
|
||||
if (isPositiveNumber(amount)) {
|
||||
// Number is > 0 and finite
|
||||
}
|
||||
```
|
||||
|
||||
#### Entity Guards:
|
||||
|
||||
```typescript
|
||||
import {
|
||||
isValidTimesheet,
|
||||
isValidInvoice,
|
||||
isValidWorker
|
||||
} from '@/lib/type-guards'
|
||||
|
||||
if (isValidTimesheet(data)) {
|
||||
// data has all required Timesheet properties
|
||||
console.log(data.workerName)
|
||||
}
|
||||
```
|
||||
|
||||
#### Collection Guards:
|
||||
|
||||
```typescript
|
||||
import { isArrayOf, isRecordOf } from '@/lib/type-guards'
|
||||
|
||||
if (isArrayOf(data, isValidTimesheet)) {
|
||||
// data is Timesheet[]
|
||||
}
|
||||
|
||||
if (isRecordOf(data, isPositiveNumber)) {
|
||||
// data is Record<string, number>
|
||||
}
|
||||
```
|
||||
|
||||
#### Property Guards:
|
||||
|
||||
```typescript
|
||||
import { hasProperty, hasProperties } from '@/lib/type-guards'
|
||||
|
||||
if (hasProperty(obj, 'email')) {
|
||||
// obj.email exists
|
||||
}
|
||||
|
||||
if (hasProperties(obj, ['id', 'name', 'email'])) {
|
||||
// All properties exist
|
||||
}
|
||||
```
|
||||
|
||||
### 6. `validation.ts`
|
||||
|
||||
Form validation with detailed error messages.
|
||||
|
||||
#### Basic Validation:
|
||||
|
||||
```typescript
|
||||
import {
|
||||
validateEmail,
|
||||
validatePassword,
|
||||
validateUsername,
|
||||
validatePhoneNumber,
|
||||
validateURL
|
||||
} from '@/lib/validation'
|
||||
|
||||
const result = validateEmail(email)
|
||||
if (!result.isValid) {
|
||||
console.log(result.errors) // Array of error messages
|
||||
}
|
||||
```
|
||||
|
||||
#### Number & Date Validation:
|
||||
|
||||
```typescript
|
||||
import {
|
||||
validateNumber,
|
||||
validateDate,
|
||||
validateDateRange
|
||||
} from '@/lib/validation'
|
||||
|
||||
const ageValidation = validateNumber(age, 18, 120, 'Age')
|
||||
const dateValidation = validateDate(startDate, 'Start Date')
|
||||
const rangeValidation = validateDateRange(start, end)
|
||||
```
|
||||
|
||||
#### File Validation:
|
||||
|
||||
```typescript
|
||||
import { validateFileSize, validateFileType } from '@/lib/validation'
|
||||
|
||||
const sizeCheck = validateFileSize(file, 10) // Max 10MB
|
||||
const typeCheck = validateFileType(file, ['pdf', 'doc', 'docx'])
|
||||
```
|
||||
|
||||
#### String Validation:
|
||||
|
||||
```typescript
|
||||
import { validateLength, validatePattern, validateRequired } from '@/lib/validation'
|
||||
|
||||
const lengthCheck = validateLength(input, 5, 50, 'Description')
|
||||
const patternCheck = validatePattern(code, /^[A-Z]{3}$/, 'Invalid format')
|
||||
const requiredCheck = validateRequired(value, 'Field Name')
|
||||
```
|
||||
|
||||
#### Form Validation:
|
||||
|
||||
```typescript
|
||||
import { validateFormData, combineValidations } from '@/lib/validation'
|
||||
|
||||
const { isValid, errors } = validateFormData(formData, {
|
||||
email: validateEmail,
|
||||
password: validatePassword,
|
||||
age: (value) => validateNumber(value, 18, 120, 'Age'),
|
||||
})
|
||||
|
||||
if (!isValid) {
|
||||
// errors is Record<string, string[]>
|
||||
console.log(errors.email) // ['Email format is invalid']
|
||||
}
|
||||
```
|
||||
|
||||
## Usage Patterns
|
||||
|
||||
### Pattern 1: Form Input Handling
|
||||
|
||||
```typescript
|
||||
import { sanitizeEmail, validateEmail } from '@/lib/utils'
|
||||
|
||||
function handleEmailChange(e: React.ChangeEvent<HTMLInputElement>) {
|
||||
const sanitized = sanitizeEmail(e.target.value)
|
||||
setEmail(sanitized)
|
||||
|
||||
const validation = validateEmail(sanitized)
|
||||
setErrors(validation.errors)
|
||||
}
|
||||
```
|
||||
|
||||
### Pattern 2: Safe Data Processing
|
||||
|
||||
```typescript
|
||||
import { isValidTimesheet, handleError } from '@/lib/utils'
|
||||
|
||||
async function processData(data: unknown[]) {
|
||||
try {
|
||||
const validTimesheets = data.filter(isValidTimesheet)
|
||||
// TypeScript knows validTimesheets is Timesheet[]
|
||||
return validTimesheets
|
||||
} catch (error) {
|
||||
handleError(error, 'Process Data')
|
||||
return []
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Pattern 3: API Error Handling
|
||||
|
||||
```typescript
|
||||
import { handleAsyncError, NetworkError } from '@/lib/utils'
|
||||
|
||||
async function fetchData() {
|
||||
const response = await handleAsyncError(
|
||||
fetch('/api/data'),
|
||||
'Fetch Data'
|
||||
)
|
||||
|
||||
if (!response) {
|
||||
// Error was already handled and shown to user
|
||||
return null
|
||||
}
|
||||
|
||||
return response.json()
|
||||
}
|
||||
```
|
||||
|
||||
### Pattern 4: Complex Validation
|
||||
|
||||
```typescript
|
||||
import {
|
||||
validateFormData,
|
||||
validateEmail,
|
||||
validateNumber,
|
||||
validateRequired
|
||||
} from '@/lib/utils'
|
||||
|
||||
const { isValid, errors } = validateFormData(formData, {
|
||||
name: (v) => validateRequired(v, 'Name'),
|
||||
email: validateEmail,
|
||||
age: (v) => validateNumber(v, 18, undefined, 'Age'),
|
||||
phone: validatePhoneNumber,
|
||||
})
|
||||
```
|
||||
|
||||
### Pattern 5: Search Query Handling
|
||||
|
||||
```typescript
|
||||
import { sanitizeSearchQuery, LIMITS } from '@/lib/utils'
|
||||
|
||||
function handleSearch(query: string) {
|
||||
const sanitized = sanitizeSearchQuery(query)
|
||||
|
||||
const results = data.filter(item =>
|
||||
item.name.toLowerCase().includes(sanitized.toLowerCase())
|
||||
).slice(0, LIMITS.MAX_SEARCH_RESULTS)
|
||||
|
||||
setResults(results)
|
||||
}
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Always Sanitize User Input
|
||||
|
||||
```typescript
|
||||
// ❌ Bad
|
||||
setEmail(e.target.value)
|
||||
|
||||
// ✅ Good
|
||||
setEmail(sanitizeEmail(e.target.value))
|
||||
```
|
||||
|
||||
### 2. Validate Before Submission
|
||||
|
||||
```typescript
|
||||
// ❌ Bad
|
||||
async function handleSubmit() {
|
||||
await api.createUser(formData)
|
||||
}
|
||||
|
||||
// ✅ Good
|
||||
async function handleSubmit() {
|
||||
const { isValid, errors } = validateFormData(formData, validators)
|
||||
|
||||
if (!isValid) {
|
||||
setFormErrors(errors)
|
||||
return
|
||||
}
|
||||
|
||||
await api.createUser(formData)
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Use Type Guards for Runtime Safety
|
||||
|
||||
```typescript
|
||||
// ❌ Bad
|
||||
function processData(data: any) {
|
||||
return data.map(item => item.name)
|
||||
}
|
||||
|
||||
// ✅ Good
|
||||
function processData(data: unknown) {
|
||||
if (!isArrayOf(data, isValidWorker)) {
|
||||
throw new ValidationError('Invalid data format')
|
||||
}
|
||||
|
||||
return data.map(worker => worker.name)
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Handle All Errors
|
||||
|
||||
```typescript
|
||||
// ❌ Bad
|
||||
async function fetchData() {
|
||||
const response = await fetch('/api/data')
|
||||
return response.json()
|
||||
}
|
||||
|
||||
// ✅ Good
|
||||
async function fetchData() {
|
||||
try {
|
||||
const response = await fetch('/api/data')
|
||||
if (!response.ok) {
|
||||
throw new NetworkError(`Failed to fetch: ${response.statusText}`)
|
||||
}
|
||||
return response.json()
|
||||
} catch (error) {
|
||||
handleError(error, 'Fetch Data')
|
||||
return null
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Use Constants Instead of Magic Values
|
||||
|
||||
```typescript
|
||||
// ❌ Bad
|
||||
setTimeout(refresh, 30000)
|
||||
if (password.length < 8) { ... }
|
||||
|
||||
// ✅ Good
|
||||
import { TIMEOUTS, LIMITS } from '@/lib/constants'
|
||||
|
||||
setTimeout(refresh, TIMEOUTS.POLLING_INTERVAL)
|
||||
if (password.length < LIMITS.MIN_PASSWORD_LENGTH) { ... }
|
||||
```
|
||||
|
||||
## Testing Utilities
|
||||
|
||||
Each utility module should be tested independently:
|
||||
|
||||
```typescript
|
||||
// Example test
|
||||
import { sanitizeEmail, validateEmail } from '@/lib/utils'
|
||||
|
||||
describe('Email utilities', () => {
|
||||
it('sanitizes email correctly', () => {
|
||||
expect(sanitizeEmail(' USER@EXAMPLE.COM ')).toBe('user@example.com')
|
||||
})
|
||||
|
||||
it('validates email format', () => {
|
||||
const result = validateEmail('invalid-email')
|
||||
expect(result.isValid).toBe(false)
|
||||
expect(result.errors).toContain('Email format is invalid')
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- **Sanitization**: Called on every input change - kept lightweight
|
||||
- **Validation**: Called on blur/submit - can be more comprehensive
|
||||
- **Type Guards**: Used in filters/maps - optimized for speed
|
||||
- **Error Handlers**: Include logging - may be async
|
||||
|
||||
## Migration Guide
|
||||
|
||||
If you're updating existing code to use these utilities:
|
||||
|
||||
1. Replace magic numbers with constants
|
||||
2. Wrap API calls in error handlers
|
||||
3. Add sanitization to all form inputs
|
||||
4. Use type guards instead of `any` types
|
||||
5. Replace custom validation with standard validators
|
||||
|
||||
## Contributing
|
||||
|
||||
When adding new utilities:
|
||||
|
||||
1. Add to appropriate module (or create new one)
|
||||
2. Export from `utils.ts`
|
||||
3. Update this README
|
||||
4. Add JSDoc comments
|
||||
5. Write tests
|
||||
6. Consider performance implications
