• Unix Philosophy + REST + JS + ... = Quiver
  
  
• Server-side component system
  
  
• New programming paradigm
  
  
• Microservice?

• Accepts key-value args and input stream
  
  
• Returns output as result stream

var helloHandler = function(args, callback) {
  callback(null, 'Hello World!')
}

exports.quiverComponents = [
  {
    name: 'demo hello handler',
    type: 'simple handler',
    inputType: 'void',
    outputType: 'text',
    handler: helloHandler
  }
]

• Simple file server serving cat pictures

$ quiver-server . --config ./config.js --main \    'quiver file directory handler'

• ImageMagick convert command

 $ convert in.jpg -resize 200 out.jpg

{
  name: 'demo resize image handler',
  type: 'stream handler',
  configOverride: {
    commandArgsExtractor: imageResizeCommandArgsExtractor,
  },
  resultContentType: 'image/jpeg',
  handler: 'quiver file convert command handler'
}

{
  name: 'demo image thumbnail handler',
  type: 'stream pipeline',
  pipeline: [
    'quiver file directory handler',
    'demo resize image handler'
  ]
}

$ quiver-server . --config ./config.js --main \

  ],
  pipeline: [
