dezalgo

Contain async insanity so that the dark pony lord doesn't eat souls

See this blog post.

USAGE

Pass a callback to dezalgo and it will ensure that it is always called in a future tick, and never in this tick.

var dz = require('dezalgo')
 
var cache = {}
function maybeSync(arg, cb) {
  cb = dz(cb)
 
  // this will actually defer to nextTick
  if (cache[arg]) cb(null, cache[arg])
 
  fs.readFile(arg, function (er, data) {
    // since this is *already* defered, it will call immediately
    if (er) cb(er)
    cb(null, cache[arg] = data)
  })
}
