# 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)
|
|
```
