My-Deferred
A tiny library to help with promises you can check and resolve from outside
Installation
Just add the npm package to your project with
npm install -S my-deferredUsage
This is how you create a deferred and resolve it later.
const def = new Deferred<string>();
// def.val will now return null;
def.promise.then((val) => {
console.log(`Promise has been resolved with ${val}!`)
})
console.log(def.isPending())
// prints true
console.log(def.isResolved())
// prints false
def.resolve("Hello World");
// will now output "Promise has been resolved with Hello World!"you can also reject the deferred using
const def = new Deferred<string>();
def.promise
.then(() => console.log("won't happen"))
.catch(err => console.log(err))
def.reject({
message: "something has gone wrong!"
});
// Will now print out "somehting has gone wrong!"
