Promise-stuff
Because promises can use a lot more stuff!
promise-stuff
is an awesome little library that adds extra functionality to your promises. It can be installed on any promise implementation or used as a set of static functions.
Using promise-stuff
There are a few ways of using the functions offerred by promise stuff.
As operators
Here is an example:
import {Operators} from 'promise-stuff'
let p = new Promise(...);
let result = Operators.lastly(p, x => {
//cleanup
});
These operators return a promise of exactly the same type as the original.
Create a new, derived promise
Create a new promise constructor from an existing one, like a native Promise
or a different implementation.
import {PromiseStuff} from 'promise-stuff';
export MyExtendedPromise = PromiseStuff.deriveNew(Promise);
let newPromise = new MyExtendedPromise(...); //promise constructor
newPromise.lastly(x => {
//cleanup
});
Install on an existing promise
import {PromiseStuff} from 'promise-stuff';
PromiseStuff.extendExisting(Promise);
let pr = new Promise(...);
pr.lastly(x => {
//cleanup
});
Examples
