## Usage
|
||||||
|
|
||||||
|
Use TypeScript for best in class instellisense.
|
||||||
|
|
||||||
|
> Note: smartq uses native ES6 promises
|
||||||
|
> smartq does not repeat any native functions, so for things like .all() simply use Promise.all()
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
import * as q from '@pushrocks/smartpromise'
|
||||||
|
|
||||||
|
// Deferred
|
||||||
|
// -----------------------------------------------
|
||||||
|
let myAsyncFunction = (): Promise<string> => {
|
||||||
|
let done = q.defer<string>() // returns your typical Deferred object
|
||||||
|
setTimeout(() => {
|
||||||
|
done.resolve('hi') // will throw type error for other types than string as argument ;)
|
||||||
|
},6000);
|
||||||
|
|
||||||
|
console.log(done.status) // logs "pending";
|
||||||
|
done.promise.then(() => {
|
||||||
|
console.log(done.status) // logs "fullfilled"
|
||||||
|
console.log(done.duration) // logs the milliseconds between instantiation and fullfillment
|
||||||
|
})
|
||||||
|
|
||||||
|
return done.promise
|
||||||
|
}
|
||||||
|
|
||||||
|
let myAsyncFunction2 = async () => {
|
||||||
|
let aString = await myAsyncFunction()
|
||||||
|
console.log(aString) // will log 'hi' to console
|
||||||
|
}
|
||||||
|
|
||||||
|
myAsyncFunction2();
|
||||||
|
|
||||||
|
|
||||||
|
// Resolved and Rejected promises
|
||||||
|
// ------------------------------------------------
|
||||||
|
q.resolvedPromise(`I'll get logged to console soon`)
|
||||||
|
.then(x => {
|
||||||
|
console.log(x)
|
||||||
|
})
|
||||||
|
|
||||||
|
q.rejectedPromise(`what a lovely error message`)
|
||||||
|
.then(() => {
|
||||||
|
console.log('This never makes it to console')
|
||||||
|
}/*, alternatively put a reject function here */)
|
||||||
|
.catch(err => {
|
||||||
|
console.log(err)
|
||||||
|
})
|
||||||
|
|
||||||
|
// Promisify (typed)
|
||||||
|
// ------------------------------------------------
|
||||||
|
|
||||||
|
let myCallbackedFunction = (someString: string, someNumber: number, cb) => {
|
||||||
|
cb(null, someString)
|
||||||
|
}
|
||||||
|
|
||||||
|
let myPromisedFunction = q.promisify(myCallbackFunction)
|
||||||
|
myPromisedFunction('helloThere', 2).then(x => {
|
||||||
|
console.log(x) // will log 'helloThere' to console
|
||||||
|
})
|
