Node - Storage Pipe Manager

Node.js idiomatic client for [Cloud Storage]

Node - Storage Pipe Manager allows world-wide storage and retrieval of any amount of data at any time. You can use Google Cloud Storage, AWS S3 Bucket for a range of scenarios including serving website content, storing data for archival and disaster recovery, or distributing large data objects to users via direct download. Storage Pipe Manager is a Pipe Factory that allow you easily switch between Google CLoud AWS S3, CLOUDINARY and FS without breaking anything or any extra configurations

Quickstart

Before you begin

Make Sure to define your credentials using enviromental vairable for AWS, Google and FS in your .zshrc or .bashrc file

Google Bucket Declaration

export GOOGLE_APPLICATION_CREDENTIALS=/Users/nitrocode/comics-eagle-39849343-837483483.json

AWS S3 Declaration

export AWS_ACCESS_KEY_ID=284893748923yuwfhsdkfjshkfjh
export AWS_SECRET_ACCESS_KEY=982u289432u48jsdfkjsr3894
export AWS_SESSION_TOKEN (optional)

Cloudinary Declaration

export CLOUDINARY_URL=cloudinary://4737858435783453:3827489jksdhfjasfhjBB@nitrocode

Digital Ocean Spaces

export DG_ACCESS_KEY=284893748923yuwfhsdkfjshkfjh
export DG_SECRET_KEY=982u289432u48jsdfkjsr3894

Local NFS Declaration

export MOUNT_POINT=/Users/nitrocode/bucket/

Would advice to declare all at once for easy switch between clients

Installing the client library

npm i node_storage_manager

Using the client library on GCLOUD

node_storage_manager allows you to switch between clients easily without reconfigurations

  // Imports the node_storage_manager library
  const Storage = require('node_storage_manager');

  // Set Storage Instance between AWS,GCLOUD and FS  
  let StorageInstance =  Storage.getInstance('GCLOUD');

  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
   // let bucketName = 'bucket-name';

    async function download(bucketName) {
      // Creates the new bucket
     await StorageInstance.download(bucketName, 'file', 'destination');
      console.log(`file downloaded`);
    }

Using the client library on AWS

  // Imports the node_storage_manager library
  const Storage = require('node_storage_manager');

  // Set Storage Instance between AWS,GCLOUD and FS  
  let StorageInstance =  Storage.getInstance('AWS');

  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
  // let bucketName = 'bucket-name';

  async function download(bucketName) {
    // Creates the new bucket
   await StorageInstance.download(bucketName, 'file', 'destination');
      console.log(`file downloaded`);
  }

Using the client library on CLOUDINARY

  // Imports the node_storage_manager library
  const Storage = require('node_storage_manager');

  // Set Storage Instance between AWS,GCLOUD and FS  
  let StorageInstance =  Storage.getInstance('CLOUDINARY');

  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
  // let bucketName = 'bucket-name';

  async function download(bucketName) {
    // Creates the new bucket
  let result = await StorageInstance.upload(bucketName, 'filepath', 'image or video');
      console.log(result);
  // This way you can get all data returned from Cloudinary Client e.g result.url e.t.c
  }

Using the client library on DigitalOcean Spaces

  // Imports the node_storage_manager library
  const Storage = require('node_storage_manager');

  // Set Storage Instance between AWS,GCLOUD and FS  
  let StorageInstance =  Storage.getInstance('DG', "Region e.g Asia");

  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
  // let bucketName = 'bucket-name';

  async function download(bucketName) {
    // Creates the new bucket
  let result = await StorageInstance.upload(bucketName, 'filepath', 'image or video');
      console.log(result);
  // This way you can get all data returned from Cloudinary Client e.g result.url e.t.c
  }

Using the client library on NFS

  // Imports the node_storage_manager library
  const Storage = require('node_storage_manager');

  // Set Storage Instance between AWS,GCLOUD and FS  
  let StorageInstance =  Storage.getInstance('NFS');

  /**
   * TODO(developer): Uncomment these variables before running the sample.
   */
  // let bucketName = 'bucket-name';

  async function download(bucketName) {
    // Creates the new bucket
   await StorageInstance.download(bucketName, 'file to download', 'destination e.g /Users/nitrocode/tmp/');
      console.log(`file downloaded`);
  }

Integration Samples

## API Documentation

StorageInstance functions

This contains a reference to the storage-pipe module. It is a valid use case to use both this module and all it’s functions

Note to specify region on S3 and DigitalOcean Spaces you need to pass it parameter on getInstance

  // Imports the node_storage_manager library
  const Storage = require('node_storage_manager');
  let StorageInstance =  Storage.getInstance('AWS'or 'DG', 'Asia');
  StorageInstance.upload()
  }

StorageInstance.download()

Download file from S3, AWS & NFS using storage pipe

parameters:

• bucketName - required, S3 bucket name to download files from.
• filename - required, file to download from bucket
• destination - required, where to put the file when done downloading

StorageInstance.upload()

Uploads file to S3, AWS & NFS using storage pipe

parameters:

• bucketName - required, S3 bucket name to upload files to.
• filename - required, file to up to bucket
• destination - optional, for renaming file during upload i.e if file bob.jpg is beign uploaded setting destination on upload method will use destination value to rename the file

parameters required if on CLOUDINARY Instance:

• bucketName - required, S3 bucket name to upload files to.
• filename - required, file to up to bucket
• fileType - required, Type of file to upload e.g image, video

StorageInstance.createBucket()

Versioning

This library follows Semantic Versioning.

This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
