## 🚀 Quick Start
### Basic Upload
```javascript
import { uploadFile } from 'cloudku-uploader'
// Simple permanent upload
const result = await uploadFile(fileBuffer, 'image.jpg')
console.log('✅ Upload URL:', result.result.url)
// Temporary upload with expiry
const tempResult = await uploadFile(fileBuffer, 'temp.pdf', '7d')
console.log('⏰ Expires in 7 days:', tempResult.result.url)
```
### Smart Upload (Recommended)
```javascript
import { uploadSmart } from 'cloudku-uploader'
// Auto-detects expiry format
const result = await uploadSmart(fileBuffer, 'document.pdf', '30d')
console.log('🎯 Smart upload:', result)
```
### Quick Time-Based Uploads
```javascript
import {
upload30s, upload15m, upload6h,
upload7d, upload3M, upload1y
} from 'cloudku-uploader'
// Ultra-fast temporary uploads
const quick = await upload30s(buffer, 'temp.jpg') // 30 seconds
const short = await upload15m(buffer, 'preview.png') // 15 minutes
const daily = await upload6h(buffer, 'report.pdf') // 6 hours
const weekly = await upload7d(buffer, 'backup.zip') // 7 days
const quarterly = await upload3M(buffer, 'archive.tar') // 3 months
const longterm = await upload1y(buffer, 'storage.mp4') // 1 year
```
## 💻 Usage Examples
### 📱 **React Component**

## 🔄 Migration Guide
### From v2.5 to v2.7
#### ✅ **What's Compatible**
- All existing `uploadFile()` calls
- Response format unchanged
- Error handling consistent
#### 🆕 **New Features to Adopt**
```javascript
// Old way (still works)
import UploadFile from 'cloudku-uploader'
const result = await new UploadFile().upload(buffer, 'file.jpg', '7d')
// New way (recommended)
import { uploadSmart } from 'cloudku-uploader'
const result = await uploadSmart(buffer, 'file.jpg', '7d')
// Even better - use shortcuts
import { upload7d } from 'cloudku-uploader'
const result = await upload7d(buffer, 'file.jpg')
```
#### 📦 **Import Changes**
```javascript
// v2.5
import UploadFile from 'cloudku-uploader'
// v2.7 - Multiple import options
import {
uploadFile, // Core function
uploadSmart, // Smart parsing
uploadBatch, // Batch processing
upload30s, // Quick shortcuts
upload7d,
upload1y,
parseExpireTime // Utility function
} from 'cloudku-uploader'
// Or import everything
import * as CloudKu from 'cloudku-uploader'
```
## 🧪 Testing & Development
### Unit Testing
```javascript
import { uploadSmart, parseExpireTime } from 'cloudku-uploader'
import { describe, it, expect } from 'vitest'
describe('CloudKu Uploader', () => {
it('should parse expiry times correctly', () => {
expect(parseExpireTime('7d')).toMatch(/^\d{4}-\d{2}-\d{2}$/)
expect(parseExpireTime('1y')).toMatch(/^\d{4}-\d{2}-\d{2}$/)
expect(parseExpireTime(null)).toBe(null)
})
it('should upload file successfully', async () => {
const buffer = new Uint8Array([0xFF, 0xD8, 0xFF]) // JPEG header
const result = await uploadSmart(buffer, 'test.jpg', '1d')
expect(result.status).toBe('success')
expect(result.result.url).toContain('cloudkuimages')
})
})
```
### Performance Testing
```javascript
import { uploadBatch } from 'cloudku-uploader'
import { performance } from 'perf_hooks'
async function benchmarkUpload() {
const files = Array.from({ length: 10 }, (_, i) => ({
buffer: new Uint8Array(1024 * 100), // 100KB each
name: `test-${i}.bin`,
expire: '1d'
}))
const start = performance.now()
const results = await uploadBatch(files)
const end = performance.now()
console.log(`⚡ Uploaded ${files.length} files in ${end - start}ms`)
console.log(`📊 Success rate: ${results.filter(r => r.status === 'fulfilled').length}/${files.length}`)
}
```
## 🌟 Advanced Use Cases

quality = 85,
format = 'jpeg',
expiry = '30d'
} = options
// Process image
const processed = await sharp(imageBuffer)
.resize(width, null, { withoutEnlargement: true })
.jpeg({ quality })
.toBuffer()
// Upload processed image
const result = await uploadSmart(
processed,
`processed-${Date.now()}.${format}`,
expiry
)
return {
...result,
originalSize: imageBuffer.length,
processedSize: processed.length,

}
}
async trackUpload(buffer, filename, expiry) {
const start = Date.now()
this.metrics.uploads++
this.metrics.totalSize += buffer.length
try {
const result = await uploadSmart(buffer, filename, expiry)
if (result.status === 'success') {
this.metrics.successes++
} else {
this.metrics.failures++
}
const responseTime = Date.now() - start
this.metrics.avgResponseTime =
(this.metrics.avgResponseTime + responseTime) / 2
return result
} catch (error) {
this.metrics.failures++
throw error
}
}
getStats() {
return {
...this.metrics,
successRate: `${(this.metrics.successes / this.metrics.uploads * 100).toFixed(2)}%`,
totalSizeMB: `${(this.metrics.totalSize / 1024 / 1024).toFixed(2)} MB`,
