s3-util

High-level utility for dealing with S3.

Enables syncronizing a local directory with a remote s3 bucket (uploading local files, deleting remote files not present locally).

Usage via the Command Line

# Install as a global executable
$ npm install -g s3-util
$ s3-util -h # print help

Usage via the API

# Install as a local package
$ npm install --save s3-util

// Inside a JavaScript file...

var s3Util = require('s3-util');

// Construct the client using keys
s3Util('my-s3-bucket', {
  awsAccessKeyId: 'abcdef',
  awsSecretAccessKey: '123456'
}).then(function(client){
  // operations on client
}).catch(function(err){
  // caught async errors
});

// Construct the client using EC2 IAM Role
s3Util('my-s3-bucket', {
  awsIAMRole: 'my-role'
}).then(function(client){
  // operations on client
}).catch(function(err){
  // caught async errors
});

// Synchronizes a local file, directory, or glob pattern with an s3 destination
// if a directory is passed in, all files in the S3 destination which are not
// present locally will be deleted.
client.sync(localSource, s3DestinationPath, uploadOptions);

client.copy(s3SourceDirectory, s3DestinationDirectory);

client.diff(localDirectoryPath, s3DirectoryPath);

client.head(s3FilePath);
client.list(s3DirectoryPath);
client.updateAcl(s3Path, aclString);

client.putStream(stream, s3DestinationPath, uploadOptions);
client.putFile(localFilePath, s3DestinationPath, uploadOptions);

client.deleteFile(s3FilePath);
client.deleteMultiple([s3FilePath1, s3FilePath2]);
client.deleteDirectory(s3DirectoryPath);
