cloud-shepherd v0.2.2

cloud-shepherd :ox: :dromedary_camel: :cow2: :water_buffalo: :ram:

STILL IN ALPHA DEVELOPMENT A promise based, multi-cloud POISIX style client wrapper that abstracts away the complexities of Object Storage services, such as AWS s3, as well as File Storage services, such as Dropbox, in order to easily interact with and move files between multiple clouds using an intuitive, familiar, and simple interface.

Amaze your friends and family as you enter the multi-cloud future and leave behind the days of having to research provider specific documentation, write complicated (and dangerous :scream:) cloud 2 cloud migration scripts, or spend time thinking about the esoteric semantics of blobs vs keys.

Installing

npm install cloud-shepherd --save

Getting Started

Require the library.

const shepherd = require('cloud-shepherd');

Call '.herd' with the name of your respective cloud provider, as well as a JSON object containing your unique access credentials to instantiate your client.

const credentials = {
    secretAccessKey : 'yourSecret',
    accessKey : 'yourAccessKey'
};

const service = 's3';

const source = shepherd.herd(service, credentials);

Methods

#####migrate(srcPath, destHerd, destPath)

Migrate a file or a directory from one Cloud to another.

    const sourceCloud = shepherd.herd('s3', srcCredentials);
    const destinationCloud = shepherd.herd('rackspace', destCredentials);

    sourceCloud.migrateFile('/sourcebucket/fileToMigrate.txt',
                            destinationCloud, 
                            '/destbucket/fileToMigrate.txt');
    
    sourceCloud.migrateDir('/cloudshepherdtesting/mydir/',
                            destinationCloud,
                            '/destinationcloudtest/testagain/');

#####ls(path)

List all files and directories in your Cloud from a given path context.

    cloud.ls('/')
        .then( data => {
            console.log(data);
        })
        .catch( err => {
            console.log(data);
        });
    
    cloud.ls('/sourcebucket/')
        .then( data => {
            console.log(data);

        .catch( err => {
            console.log(data);
        });
    
    cloud.ls('/sourcebucket/dir/sub-dir/')
        .then( data => {
            console.log(data);
        })
        .catch( err => {
            console.log(data);
        });                  

#####stat(path)

List detailed information about files and/or directories from a given path context.

    cloud.stat('/sourcebucket/fileToMigrate.txt')
        .then( data => {
            console.log(data);
        })
        .catch( err => {
            console.log(data);
        });

####mkdir(path)

Create a directory at the given path.

    cloud.mkdir('/sourcebucket/')
        .then( data => {
            console.log(data);
        })
        .catch( err => {
            console.log(err);
        });

####uploadFile(writePath,readStream)

Upload a file to the given write path context, from a given Readable stream.

        const Readable = require('stream').Readable;
        const readStream = Readable({objectMode: true});
        
        readStream._read = () => {};
        readStream.push('buffalo');
        readStream.push('yaks');
        readStream.push(null);
        
        cloud.uploadFile( '/testingdirs/fileToWrite.txt', readStream)
            .then(data => {
                console.log('Successfully placed file');
            })
            .catch(err => {
                console.log(err);
            });
        
       

####downloadFile(readPath,writeStream)

Read the data from a given path, and write that data to a given Writable stream.

    cloud.downloadFile( '/testingdirs/fileToWrite.txt', process.stdout)
        .then(data => {
            console.log('Successfully placed file');
        });

####unlink(path)

Delete a file or dir from a given path context.

    cloud.unlink('/container/dir/subdirtodelete/')
             .then(item => {
                 console.log(item);
             });

####destroy(path)

A destroy file and destroy dir method have been implemented, to give you peice of mind while removing items. These methods will throw an error if you accidentally delete a file instead of a dir and vice versa.

    cloud.destroyFile('/testingdirs/fileToWrite3.txt')
        .then((file) => {
            console.log('Successfully destroyed file:' + file);
        });
            
    cloud.destroyDir('/testingdirs/')

            console.log('Successfully destroyed file:' + dir);
        });

NOT YET IMPLEMENTED:: empty(path)

Will delete all items from a supplied directory context, but will not delete the directory.

    cloud.emptyDir('/container/dir/')
        .then(data => {
            console.log(data);
        })
        .catch((err) => {
            console.log(err);

            console.log(data);
        })
        .catch((err) => {
            console.log(err);
        });

####itemExists(path)

    cloud.fileExists('/gigofbuffalos/buffalo.jpg')
        .then(doesFileExist => {
            console.log('Does file exist? : ', doesFileExist );
        })
        .catch((err) => {
            console.log(err);
        });
    cloud.dirExists('/containertodelete/dir/subdir/')
        .then(doesFileExist => {
            console.log('Does dir exist? : ', doesFileExist );
        })
        .catch((err) => {
            console.log(err);
        });
    cloud.rootDirExists('/containertodelete/')

            console.log('Does root dir exist? : ', doesFileExist );
        })
        .catch((err) => {
            console.log(err);
        });

        .then(data => {
            console.log(data);
            console.log('Successfully copied file');
        })
        .catch((err) => {
            console.log(err);
        });
        
    cloud.copyDir('/cloudshepherdtesting/copytest/', 
                    '/cloudshepherdtesting/')
        .then(data => {

        .then(data => {
            console.log(data);
