Keg

Keg is a messaging queue. It's not suitable for production yet. Expect things to break & change without notice. It includes TypeScript support.

Installation

npm i @joduplessis/keg

Terminology

It's helpful to think in these terms:

• Keg: overall queue ID
• Tap: outlet of messages received, identified by an ID
• Spike: a reduce orientated middleware for messages
• Refill: adds a new message to a keg:tap
• pour(): something like a next() to move through the queue

Some example usage:

Keg.keg('kegger').tap('demo', async (val, pour) => {
  // 'val' is the current value for the demo queue
  // We can process it here
  // And then move onto the next item in the queue
  // Equivalent to next()
  pour()
}, () => {
  // Tap is empty
})

// Add middleware to each message
Keg.keg('kegger').spike('demo', in => {
  return window.btoa(in)
})

Keg.keg('kegger').refill('demo', 'Some text')
Keg.keg('kegger').refill('demo', { order: 'Object message types' })
Keg.keg('kegger').refill('demo', 42)

Spiking your drink

Any middleware that gets added will act as a pipe. It take the value in & passes it onto the next spike().
