Identity:: s3

API docs

Description

This adapter provides interface for Nodestream to transfer bytes between your app and Amazon S3 cloud storage.

Usage

Installation

npm install --save nodestream-s3

Configuration

When configuring Nodestream instance, the only required option is the bucket. The rest is optional and is passed along unmodified to the AWS.S3() constructor. No default values are provided.

const Nodestream = require('nodestream')
const nodestream = new Nodestream({
  adapter: 's3',
  config: {
    // Required - cannot do anything without a bucket!
    bucket: 'my-s3-bucket',
    // The rest of the options is passed as-is to the AWS.S3() constructor
    // NOTE: You will probably need the AWS credentials here 😀
    accessKeyId: 'my-access-key-id',
    secretAccessKey: 'my-secret!'
  }
})

Usage

Uploading

When uploading files, you may specify a directory and name for the upload. Both are optional - if no name is given, a random GUID will be generated.

You can also specify custom options for the upload() method to specify options like ACL or part size for multipart uploads.

const file = fs.createReadStream('/users/me/profile-pic.png')
nodestream.upload(file, {
  directory: 'avatars',
  name: 'user-123.png',
  s3: {
    // This corresponds to the first argument of the S3.upload() method
    // NOTE: Specifying `Key`, `Body` or `Bucket` here will have no effect
    params: {
      ACL: 'public-read'
    },
    // This corresponds to the second argument of the S3.upload() method
    options: {
      partSize: 10 * 1024 * 1024
    }
  }
})

Downloading

You can also specify options for the getObject() method via s3 object (this adapter's identity) in the third argument.

const dest = fs.createWriteStream('/users/me/profile-pic.png')
nodestream.download('avatars/user-123.png', dest, {
  s3: {
    Range: '1000-'
  }
})
 
// Perhaps in an Express controller, you would pipe the file to the client
res.setHeader('content-type', 'image/png')
res.setHeader('content-disposition', 'attachment')
nodestream.download('avatars/user-123.png', res)
.then(results => {
  // Client received the file
})
