+# inflight
+
+Add callbacks to requests in flight to avoid async duplication
+
+## USAGE
+
+```javascript
+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)
+req('foo', cb3)
+req('foo', cb4)
+```
