or

yarn add omni-cloud

Usage

Configuration

Configure OmniCloud with the necessary credentials for your chosen cloud storage providers.

import { ProviderFactory, IStorageProvider } from 'omni-cloud';

const storageConfig = {
  provider: 'aws',
  aws: {
    credentials: {
    accessKeyId: 'your-access-key-id',
    secretAccessKey: 'your-secret-access-key',
    },
    region: 'your-region',
    bucketName: 'your-bucket-name',
  },
};

const storage: IStorageProvider = ProviderFactory.createProvider(storageConfig);

Upload a File

From File System

async function uploadFileFromFileSystem() {
  try {
    await storage.uploadFile('path/to/local/file.txt', 'remote/file.txt');
    console.log('File uploaded successfully');
  } catch (error) {
    console.error('Error uploading file:', error);
  }
}

From Buffer

async function uploadFileFromBuffer(fileBuffer) {
  try {
    await storage.uploadFile(fileBuffer, 'remote/file.txt');
    console.log('File uploaded successfully');
  } catch (error) {
    console.error('Error uploading file:', error);
  }
}

From Stream

async function uploadFileFromStream(fileStream) {
  try {
    await storage.uploadFile(fileStream, 'remote/file.txt');
    console.log('File uploaded successfully');
  } catch (error) {
    console.error('Error uploading file:', error);
  }
}

Download a File

To File System

async function downloadFileToFileSystem() {
  await storage.downloadFile('remote/file.txt', { type: 'file', destination: 'path/to/local/file.txt' });
  console.log('File downloaded successfully');
}

To Buffer

async function downloadFileToBuffer() {
  return await storage.downloadFile('remote/file.txt', { type: 'buffer' });
}

To Stream

import * as fs from 'node:fs';

async function downloadFileToStream() {
  return await storage.downloadFile('remote/file.txt', { type: 'stream' });
}

Delete a File

async function deleteFile() {
  await storage.delete('remote/file.txt');
  console.log('File deleted successfully');
}

API

ProviderFactory.createProvider(config: IStorageConfig): IStorageProvider

Creates a new instance of a cloud storage provider based on the specified configuration.

uploadFile(source: string | Buffer | Stream, destination: string): Promise

Uploads a file from the local filesystem, buffer, or stream to the specified remote path in the configured cloud storage provider.

downloadFile(remotePath: string, options: { type: 'buffer' | 'stream' | 'file', destination?: string }): Promise

Downloads a file from the specified remote path in the configured cloud storage provider to the local filesystem, buffer, or stream.

delete(filePath: string): Promise

Deletes the file at the specified path in the configured cloud storage provider.
