Node 6.1

Node 0.6.1 was released a few days ago, which adds improvements to documenation, cluster, and includes a host of bug fixes.

Scaffoldit

Scaffoldit (npm: scaffoldit) by Craig Condon is a scaffolding library that makes it easy to take user input and display data using templates. Templates can be written using mustache, and it has command-line support through Craig’s celeri library.

One of the examples reminds me of skeleton app generators that come with frameworks like Express:

scaffoldit({
  input: {
    projectName: 'What is your project name?'
  },

  build: function(ops, next) {
    scaffoldit.fromDir(ops, '/path/to/input/dir', '/path/to/output/dir');
  },

  complete: function() {
    //...
  }
});

Also worth noting is Tim Caswell’s Step library is used to simplify the internal asynchronous code.

Mixture

Mixture (License: MIT, npm: mixture) is a “heterogeneous cluster task manager” by Daniel Shaw. It can be used to programmatically create a diverse set of forked tasks using a straightforward API:

var mix = require('mixture').mix()
  , ioPort = 8880
  , nodeId = 0
  , i
  , workers = [];

// announce data server
mix.task('announce').fork('data.js');

// socket.io instances
var socketio = mix.task('socket.io', { filename: 'app.js' })

for (i = 0; i < count; i++) {
  ioPort++;
  nodeId++;
  workers.push(socketio.fork({ args: [ioPort, nodeId] }));
}

// At some point, workers[n].kill() could be called

Daniel has written an example app that uses the library, called Stock Quote Stream.
