sync-cloud-storage

sync-cloud-storage is a Node.js package designed to seamlessly synchronize files and directories between local environments and cloud storage providers like AWS S3. It leverages AWS SAM (Serverless) and AWS Cloud Development Kit (CDK) for powerful, modern, and flexible integrations.

Features

• Sync multiple storage at once
• Use pattern matching on finding files (single or multiple file/dir sync) by defining patterns of glob to include or exclude
• Supports a set of options as following for each file based on storage features: Prefix, Access Control List (ACL), Tags, Metadata
• Modern and uses the latest official cloud provider's SDK
  • AWS S3: aws-sdk@3.x

Installation

• npm: npm i sync-cloud-storage
• yarn: yarn add sync-cloud-storage
• pnpm: pnpm add sync-cloud-storage
• ni: ni sync-cloud-storage

Usage

AWS S3

Serverless

The integration is powered by Serverless hooks and In below, the default configured hooks are listed:

• scs:storages -> As a CLI command for serverless
• scs:tags -> As a CLI command for serverless
• scs:metadata -> As a CLI command for serverless
• before:offline:start:init -> Sync storages (scs:storages)
• before:deploy:deploy -> Sync storages (scs:storages)

Example

This setup uses before:deploy:deploy hook to sync storages before deploying the stack:

plugins:
  - sync-cloud-storage

custom:
  syncCloudStorage:
    - name: my-bucket
      patterns:
        - assets/*
      actions:
        - upload
        - delete
      prefix: assets
      acl: public-read
      metadata:
        foo: bar
        bar: foo
      tags:
        foo: bar
        bar: foo

CDK

Call storages action to sync after setting up a CDK App and Stack:

import { Stack, App } from '@aws-cdk/core'
import SyncCloudStorage from 'sync-cloud-storage'

const app = new App()
const stack = new Stack(app, 'MyStack')
const syncCloudStorage = new SyncCloudStorage(stack, {
  storages: [
    {
      name: 'my-bucket',
      patterns: ['assets/*'],
      actions: ['upload', 'delete'],
      prefix: 'assets',
      acl: 'public-read',
      metadata: {
        foo: 'bar',
        bar: 'foo',
      },
    },
  ],
})

syncCloudStorage.storages()
