Package Exports

cloudku-uploader
cloudku-uploader/src/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cloudku-uploader) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

🚀 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>
  )
}

🚀 Express.js API

import express from 'express'
import multer from 'multer'
import { uploadSmart, uploadBatch } from 'cloudku-uploader'

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

// Single file upload
app.post('/upload', upload.single('file'), async (req, res) => {
  try {
    const { buffer, originalname } = req.file
    const expiry = req.body.expiry || null
    
    const result = await uploadSmart(buffer, originalname, expiry)
    
    if (result.status === 'success') {
      res.json({
        success: true,
        data: {
          url: result.result.url,
          filename: result.result.filename,
          size: result.result.size,
          expires: expiry ? `in ${expiry}` : 'never'
        }
      })
    } else {
      res.status(400).json({ error: result.message })
    }
  } catch (error) {
    res.status(500).json({ error: error.message })
  }
})

// Batch upload
app.post('/upload/batch', upload.array('files'), async (req, res) => {
  try {
    const files = req.files.map(file => ({
      buffer: file.buffer,
      name: file.originalname,
      expire: req.body.expiry || null
    }))
    
    const results = await uploadBatch(files)
    
    res.json({
      success: true,
      total: files.length,
      results: results.map(r => ({
        status: r.status,
        data: r.data?.result || null,
        error: r.error?.message || null
      }))
    })
  } catch (error) {
    res.status(500).json({ error: error.message })
  }
})

app.listen(3000, () => {
  console.log('🚀 Server running on port 3000')
})

🔄 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,
  filename: r.data?.result?.filename || 'failed',
  url: r.data?.result?.url || 'N/A'
})))

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
