🚀 Quick Start

Basic Upload

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)

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

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

import React, { useState } from 'react'
import { uploadSmart } from 'cloudku-uploader'

function FileUploader() {
  const [uploading, setUploading] = useState(false)
  const [result, setResult] = useState(null)

  const handleUpload = async (file, expiry = null) => {
    setUploading(true)
    try {
      const buffer = await file.arrayBuffer()
      const response = await uploadSmart(
        new Uint8Array(buffer), 
        file.name, 
        expiry
      )
      setResult(response)
    } catch (error) {
      console.error('Upload failed:', error)
    } finally {
      setUploading(false)
    }
  }

  return (
    <div className="upload-container">
      <input 
        type="file" 
        onChange={(e) => handleUpload(e.target.files[0], '7d')}
        disabled={uploading}
      />
      {uploading && <p>⏳ Uploading...</p>}
      {result && (
        <div>
          <p>✅ Success!</p>
          <a href={result.result.url} target="_blank">
            View File: {result.result.filename}
          </a>
        </div>
      )}
    </div>

const app = express()
const upload = multer({ 
  limits: { fileSize: 100 * 1024 * 1024 }, // 100MB

🔄 Batch Processing

import { uploadBatch, upload7d } from 'cloudku-uploader'
import fs from 'fs'
import path from 'path'

class BatchUploader {
  async uploadDirectory(dirPath, options = {}) {
    const { concurrency = 3, expiry = null } = options
    
    const files = fs.readdirSync(dirPath)
      .map(filename => ({
        buffer: fs.readFileSync(path.join(dirPath, filename)),
        name: filename,
        expire: expiry
      }))
    
    console.log(`📦 Processing ${files.length} files...`)
    
    // Process in batches for better performance
    const results = []
    for (let i = 0; i < files.length; i += concurrency) {
      const batch = files.slice(i, i + concurrency)
      const batchResults = await uploadBatch(batch)
      results.push(...batchResults)
      
      console.log(`✅ Processed batch ${Math.ceil((i + 1) / concurrency)}`)
    }
    
    return results
  }
}

// Usage
const uploader = new BatchUploader()
const results = await uploader.uploadDirectory('./uploads', {
  concurrency: 5,
  expiry: '30d'
})

console.table(results.map(r => ({
  status: r.status,

🔄 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

// 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

// v2.5
import UploadFile from 'cloudku-uploader'

// v2.7 - Multiple import options
