inflight
Add callbacks to requests in flight to avoid async duplication
USAGE
var inflight = require('inflight')
// some request that does some stuff
function req(key, callback) {
// key is any random string. like a url or filename or whatever.
//
// will return either a falsey value, indicating that the
// request for this key is already in flight, or a new callback
// which when called will call all callbacks passed to inflightk
// with the same key
callback = inflight(key, callback)
// If we got a falsey value back, then there's already a req going
if (!callback) return
// this is where you'd fetch the url or whatever
// callback is also once()-ified, so it can safely be assigned
// to multiple events etc. First call wins.
setTimeout(function() {
callback(null, key)
}, 100)
}
// only assigns a single setTimeout
// when it dings, all cbs get called
req('foo', cb1)
req('foo', cb2)
