- // some request that does some stuff
- function req(key) {
- // key is any random string. like a url or filename or whatever.
- return inflight(key, () => {
- // this is where you'd fetch the url or whatever
- return Promise.delay(100)
- })
- }
- // only assigns a single setTimeout
- // when it dings, all thens get called with the same result. (There's only
- // one underlying promise.)
- req('foo').then(…)
- req('foo').then(…)
- req('foo').then(…)
- req('foo').then(…)
- ```
