s3 folder upload

Little script to upload statics to a S3 bucket by using official Amazon SDK.

AWS Credentials

In order to use this module, you'll need to have AWS Credentials. You can load them, two ways:

By passing directly to the method as second parameter.
By having a ENV variable with the path to a file with the credentials. The ENV variable is AWS_CREDENTIALS_PATH and it should have accessKeyId, secretAccessKey, region and bucket.

Install

npm install s3-folder-upload -D

In case you want to use the CLI, you can install it globally:

npx s3-folder-upload

Require

const s3UploadFolder = require('s3-folder-upload')
// ES6: import s3UploadFolder from 's3-folder-upload'

const directoryName = 'statics'
// I strongly recommend to save your credentials on a JSON or ENV variables, or command line args
const credentials = {
  "accessKeyId": "<Your Access Key Id>",
  "secretAccessKey": "<Your Secret Access Key>",
  "region": "<Your Aimed Region>",
  "bucket": "<Your Bucket Name>"
}

// optional options to be passed as parameter to the method
const options = {
  useFoldersForFileTypes: false,
  useIAMRoleCredentials: false
}

// optional cloudfront invalidation rule
const invalidation = {
    awsDistributionId: "<Your CloudFront Distribution Id>",
    awsInvalidationPath: "<The Path to Invalidate>"
}

s3FolderUpload(directoryName, credentials, options, invalidation)

Options

useFoldersForFileTypes (default: true) - Upload files to a specific subdirectory according to its file type.

useIAMRoleCredentials (default: false) - It will ignore all the credentials passed via parameters or environment variables in order to use the instance IAM credentials profile.

uploadFolder (default: undefined) - If it's specified, the statics will be uploaded to the folder, so if you upload static.js to https://statics.s3.eu-west-1.amazonaws.com with a uploadFolder with value my-statics the file will be uploaded to: https://statics.s3.eu-west-1.amazonaws.com/my-statics/static.js.

CLI

s3-folder-upload <folder>

Example:
s3-folder-upload statics

For the AWS Credentials

you can define a ENV variable called AWS_CREDENTIALS_PATH with the path of the file with the needed info.

you can pass the needed info via command line parameters:

s3-folder-upload <folder> --accessKeyId=<your access key id> --bucket=<destination bucket> --region=<region> --secretAccessKey=<your secret access key>

you can use useIAMRoleCredentials option in order to rely on IAM Profile instance instead any passed by variables and environment

For Options

you can pass the needed info via command line parameters:

s3-folder-upload <folder> <credentials parameters> --useFoldersForFileTypes=false

For CloudFront invalidation

you can pass the needed info via command line parameters, the invalidation needs both parameters:

s3-folder-upload <folder> <credentials parameters> --awsDistributionId=<distributionId> --awsInvalidationPath="/js/*"

Wish list

Upload a entire folder to S3 instead file
Async upload of files to improve time
Detect automatically the content type of (limited support)
Return the list of files uploaded with the final URL
Better support for parameters with the CLI
Improve content type function in order to get more and better types of files
Avoid to re-upload files if they didn't change
Check if cache is blocking updates of statics on website.
Map uploaded paths to create a default invalidation paths rule in CloudFront.
