A Node.js package that provides an easy interface to upload and manage files on both Cloudinary and AWS S3. This package supports both JavaScript and TypeScript projects, making it versatile and easy to integrate into various environments.

Table of Contents

Installation

To install the package, use npm or yarn:

npm install multi-cloud-upload

or

yarn add multi-cloud-upload

Features

  • Supports Cloudinary and AWS S3: Easily switch between Cloudinary and AWS S3 for file uploads and management.
  • Compatible with JavaScript and TypeScript: Includes type definitions for TypeScript support.
  • Simple and Extensible: Easy-to-use interface that can be extended to support additional cloud services.

Usage

JavaScript

const {StorageFactory} = require ("multi-cloud-upload")
const fs = require("fs")
const path = require("path")
require("dotenv").config();

// Load configurations from environment variables
const accessKeyId = process.env.AWS_ACCESS_KEY_ID || '';
const secretAccessKey = process.env.AWS_SECRET_ACCESS_KEY || '';
const region = process.env.AWS_REGION || '';
const bucket = process.env.AWS_BUCKET || '';

const cloudinaryConfig = {
  cloud_name: process.env.CLOUDINARY_CLOUD_NAME || '',
  api_key: process.env.CLOUDINARY_API_KEY || '',
  api_secret: process.env.CLOUDINARY_API_SECRET || '',
  // additional params can go in here.
};


const s3Config = {
  accessKeyId: accessKeyId,
  secretAccessKey: secretAccessKey,
  region: region,
  bucket: bucket,

};

const cloudinaryProvider = StorageFactory.createProvider('cloudinary', cloudinaryConfig);
const s3Provider = StorageFactory.createProvider('s3', s3Config);

// Read the actual image file into a buffer
const filePath = path.join(__dirname, 'test.png');
const fileBuffer = fs.readFileSync(filePath);

console.log(fileBuffer, "sdfnjbfdvbfd");


// Now you can use either provider with the same interface
(async () => {
    let context = {}
    // upload
    const example1 = await cloudinaryProvider.upload(fileBuffer, 'example.png', context);
    const example2 = await cloudinaryProvider.download('example.png', context);
    const example3 = await cloudinaryProvider.list(context);
    const example4 = await cloudinaryProvider.delete('example.png', context);
    const example5 = await cloudinaryProvider.getUrl('gccyckcnbpcy5vx8gjyd', context);
  
  
    // // upload file
    const example6 = await s3Provider.upload(fileBuffer, 'examplex.png', {ContentType: 'image/png'} );
    // donwload file
    const example7 = await s3Provider.download("examplex.png", context)
    // delete object
    const example8 = await s3Provider.delete('examplex.png',context)
    // list objects
    context = {MaxKeys:5, ContinuationToken: 'xyz'}
    const example9 = await s3Provider.list(context)
    // get single object
    context = {expiresIn: 60 * 1}
    const example10 = s3Provider.getUrl('examplex.png', context)
  

})()
  

TypeScript

// Usage example
import {StorageFactory} from "multi-cloud-upload"
import * as dotenv from 'dotenv';
import * as fs from 'fs';
import * as path from 'path';
dotenv.config(); 

// Load configurations from environment variables
const accessKeyId = process.env.AWS_ACCESS_KEY_ID || '';
const secretAccessKey = process.env.AWS_SECRET_ACCESS_KEY || '';
const region = process.env.AWS_REGION || '';
const bucket = process.env.AWS_BUCKET || '';

const cloudinaryConfig = {
  cloud_name: process.env.CLOUDINARY_CLOUD_NAME || '',
  api_key: process.env.CLOUDINARY_API_KEY || '',
  api_secret: process.env.CLOUDINARY_API_SECRET || '',
};

const s3Config = {
    accessKeyId: accessKeyId,
    secretAccessKey: secretAccessKey,
    region: region,
    bucket: bucket,
  
  };

const cloudinaryProvider = StorageFactory.createProvider('cloudinary', cloudinaryConfig);
const s3Provider = StorageFactory.createProvider('s3', s3Config);

// Read the actual image file into a buffer
const filePath = path.join(__dirname, 'test.png');
const fileBuffer = fs.readFileSync(filePath);

// Now you can use either provider with the same interface
(async () => {
    let context = {}
    // upload
    const example1 = await cloudinaryProvider.upload(fileBuffer, 'example.png', context);
    const example2 = await cloudinaryProvider.download('example.png', context);
    const example3 = await cloudinaryProvider.list(context);
    const example4 = await cloudinaryProvider.delete('example.png', context);
    const example5 = await cloudinaryProvider.getUrl('gccyckcnbpcy5vx8gjyd', context);
  
  
    // // upload file
    const example6 = await s3Provider.upload(fileBuffer, 'examplex.png', {ContentType: 'image/png'} );
    // donwload file
    const example7 = await s3Provider.download("examplex.png", context)
    // delete object
    const example8 = await s3Provider.delete('examplex.png',context)
    // list objects
    context = {MaxKeys:5, ContinuationToken: 'xyz'}
    const example9 = await s3Provider.list(context)
    // get single object
    context = {expiresIn: 60 * 1}
    const example10 = s3Provider.getUrl('examplex.png', context)
  

})()

Configuration

  • options: Optional parameters for the upload.

download(fileName: string, context: object={}): Promise<any>

  • fileName: The name of the file to be downloaded.
  • options: Optional parameters for the download.

delete(fileName: string, context: object={}): Promise<any>

  • fileName: The name of the file to be deleted.
  • options: Optional parameters for the delete operation.

list(context: object={}): Promise<string[]>

  • options: Optional parameters for listing files.
  • Returns: A Promise that resolves to an array of file names.

getUrl(fileName: string, context: object={}): Promise<string>

  • fileName: The name of the file for which to generate the URL.
  • options: Optional parameters.
  • Returns: A Promise that resolves to the pre-signed URL.

CloudinaryProvider

list(context: object={}): Promise<string[]>

Lists files from Cloudinary.

getUrl(fileName: string, context: object={}): Promise<string>

Generates a URL for accessing a file in Cloudinary.

S3Provider

The S3Provider class implements the StorageProvider interface for AWS S3.

upload(file: Buffer, fileName: string, context: object={}): Promise<any>

Uploads a file to an S3 bucket.

download(fileName: string, context: object={}): Promise<any>

Downloads a file from an S3 bucket.

delete(fileName: string, context: object={}): Promise<any>

Deletes a file from an S3 bucket.

list(context: object={}): Promise<string[]>
