This module is designed to be used with TypeScript for the best developer experience, providing type safety and IntelliSense in your IDE.
|
||||
|
||||
## Usage
|
||||
|
||||
Use TypeScript for best in class instellisense.
|
||||
`@push.rocks/smartpromise` simplifies the use of promises and deferred constructs in TypeScript, offering a set of utility functions that extend native Promise capabilities in specific scenarios. This guide walks you through its functionalities, showcasing how to leverage this library in a TypeScript project.
|
||||
|
||||
> Note: smartq uses native ES6 promises
|
||||
> smartq does not repeat any native functions, so for things like .all() simply use Promise.all()
|
||||
### Setting Up Your Project
|
||||
|
||||
```typescript
|
||||
import * as q from '@pushrocks/smartpromise';
|
||||
Ensure your TypeScript project is configured to support ES Module syntax. In your `tsconfig.json`, you should have:
|
||||
|
||||
// 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
|
||||
});
|
||||

||||
#### Creating a Deferred
|
||||
|
||||
For further information read the linked docs at the top of this readme.
|
||||
Deferred objects in `@push.rocks/smartpromise` give you more control over your promises, allowing for manual resolution or rejection beyond the initial executor function.

|
||||
```typescript
|
||||
import { defer } from '@push.rocks/smartpromise';
|
||||
|
||||
async function exampleDeferred(): Promise<string> {
|
||||
const myDeferred = defer<string>();
|
||||
|
||||
// Simulate an async task
|
||||
setTimeout(() => {
|
||||
myDeferred.resolve('Hello, Deferred!');
|
||||
}, 1000);
|
||||
|
||||
return myDeferred.promise;
|
||||
}
|
||||
|
||||
exampleDeferred().then((result) => console.log(result));
|
||||
```
|
||||
|
||||
#### Cumulative Deferred
|
||||
|
||||
For scenarios where multiple asynchronous tasks need to be tracked collectively before proceeding, use `CumulativeDeferred`. It waits for all added promises to resolve.
|
||||
|
||||
```typescript
|
||||
import { cumulativeDefer } from '@push.rocks/smartpromise';
|
||||
|
||||
async function exampleCumulativeDeferred() {
|
||||
const myCumulativeDeferred = cumulativeDefer();
|
||||
|
||||
for (let i = 0; i < 5; i++) {
|
||||
myCumulativeDeferred.addPromise(new Promise((resolve) => setTimeout(resolve, 1000 * i)));
|
||||
}
|
||||
|
||||
await myCumulativeDeferred.promise;
|
||||
console.log('All tasks completed!');
|
||||
}
|
||||
|
||||
exampleCumulativeDeferred();
|
||||
```
|
||||
|
||||
#### Utilizing Resolved and Rejected Promises
|
||||
|
||||
Quickly create already resolved or rejected promises for testing or initialization purposes.
|
||||
|
||||
```typescript
|
||||
import { resolvedPromise, rejectedPromise } from '@push.rocks/smartpromise';
|
||||
|
||||
resolvedPromise('immediately resolved').then(console.log);
|
||||
rejectedPromise('immediately rejected').catch(console.error);
|
||||
```
|
||||
|
||||
### Advanced Use Cases
|
||||
|
||||
#### Promisify Callback Functions
|
||||
|
||||
`@push.rocks/smartpromise` does not directly provide a `promisify` function like Node.js `util` module, but you can easily integrate existing functions or use third-party libraries to convert callback-based functions into promises.
|
||||
|
||||
#### Handling Timeouts and Continuations
|
||||
|
||||
Managing timeouts or long-running promises gets easier with helper functions.
|
||||
|
||||
```typescript
|
||||
import { timeoutWrap, timeoutAndContinue } from '@push.rocks/smartpromise';
|
||||
|
||||
async function exampleTimeout() {
|
||||
const myPromise = new Promise((resolve) => setTimeout(() => resolve('Done!'), 2000));
|
||||
|
||||
// Will reject if the promise does not resolve within 1 second
|
||||
try {
|
||||
const result = await timeoutWrap(myPromise, 1000);
|
||||
console.log(result);
|
||||
} catch (error) {
|
||||
console.error('Promise timed out');
|
||||
}
|
||||
|
||||
// Continues after 1 second, regardless of whether the promise has resolved
|
||||
const result = await timeoutAndContinue(myPromise, 1000);
|
||||
console.log(result); // May log `null` if the original promise did not resolve in time
|
||||
}
|
||||
|
||||
exampleTimeout();
|
||||
```
|
||||
|
||||
#### Map and Reduce Asynchronous Functions
|
||||
|
||||
Suppose you have a collection of items that you need to process asynchronously. You can use the `map` function to apply an asynchronous function to each item in the array and wait for all the promises to resolve.
|
||||
|
||||
```typescript
|
||||
import { map } from '@push.rocks/smartpromise';
|
||||
|
||||
async function processData(items: string[]): Promise<string[]> {
|
||||
return map(items, async (item) => {
|
||||
// Simulate an async operation
|
||||
await new Promise((resolve) => setTimeout(resolve, 100));
|
||||
return item.toUpperCase();
|
||||
});
|
||||
}
|
||||
|
||||
processData(['hello', 'world']).then(console.log);
|
||||
```
|
||||
|
||||
### Handling Complex Promise Scenarios
|
||||
|
||||
#### Managing Multiple Deferreds
|
||||
|
||||
If you have multiple deferred objects and you want to manage them collectively, you can do so using the `CumulativeDeferred` class. This is especially useful when you have a dynamic number of deferreds to resolve.
|
||||
|
||||
```typescript
|
||||
import { defer, cumulativeDefer } from '@push.rocks/smartpromise';
|
||||
|
||||
async function exampleComplexDeferred(): Promise<void> {
|
||||
const task1 = defer<string>();
|
||||
const task2 = defer<string>();
|
||||
const cumulative = cumulativeDefer();
|
||||
|
||||
cumulative.addPromise(task1.promise);
|
||||
cumulative.addPromise(task2.promise);
|
||||
|
||||
// Simulate async tasks
|
||||
setTimeout(() => task1.resolve('Task 1 complete'), 1000);
|
||||
setTimeout(() => task2.resolve('Task 2 complete'), 2000);
|
||||
|
||||
await cumulative.promise;
|
||||
|
||||
console.log('All tasks completed');
|
||||
}
|
||||
|
||||
exampleComplexDeferred();
|
||||
```
|
||||
|
||||
### Other Utilities
|
||||
|
||||
#### Race Condition Handling with `getFirstTrueOrFalse`
|
||||
|
||||
This helper function resolves immediately when one of the provided promises resolves to `true` or when all promises are resolved to `false`.
|
||||
|
||||
```typescript
|
||||
import { getFirstTrueOrFalse } from '@push.rocks/smartpromise';
|
||||
|
||||
async function exampleRaceCondition() {
|
||||
const task1 = new Promise<boolean>((resolve) => setTimeout(() => resolve(true), 1000));
|
||||
const task2 = new Promise<boolean>((resolve) => setTimeout(() => resolve(false), 2000));
|
||||
|
||||
const result = await getFirstTrueOrFalse([task1, task2]);
|
||||
console.log(result); // Outputs: true
|
||||
}
|
||||
|
||||
exampleRaceCondition();
|
||||
```
|
||||
|
||||
### Complete Use Case
|
||||
|
||||
Let's create a comprehensive example that showcases multiple features of `@push.rocks/smartpromise`.
|
||||
|
||||
```typescript
|
||||
import {
|
||||
defer,
|
||||
cumulativeDefer,
|
||||
resolvedPromise,
|
||||
rejectedPromise,
|
||||
timeoutWrap,
|
||||
timeoutAndContinue,
|
||||
map,
|
||||
getFirstTrueOrFalse,
|
||||
} from '@push.rocks/smartpromise';
|
||||
|
||||
async function completeUseCaseExample() {
|
||||
console.log('Starting Complete Use Case Example!');
|
||||
|
||||
// Using Deferred
|
||||
const myDeferred = defer<string>();
|
||||
setTimeout(() => myDeferred.resolve('Deferred Resolved!'), 500);
|
||||
console.log(await myDeferred.promise); // Outputs: "Deferred Resolved!"
|
||||
|
||||
// Using Cumulative Deferred
|
||||
const myCumulativeDeferred = cumulativeDefer();
|
||||
myCumulativeDeferred.addPromise(new Promise((resolve) => setTimeout(() => resolve('Task 1'), 1000)));
|
||||
myCumulativeDeferred.addPromise(new Promise((resolve) => setTimeout(() => resolve('Task 2'), 2000)));
|
||||
await myCumulativeDeferred.promise;
|
||||
console.log('All cumulative tasks completed');
|
||||
|
||||
// Using Resolved and Rejected Promises
|
||||
await resolvedPromise('Instant Resolve').then(console.log); // Outputs: "Instant Resolve"
|
||||
await rejectedPromise('Instant Reject').catch(console.error); // Outputs: "Instant Reject"
|
||||
|
||||
// Using timeoutWrap
|
||||
try {
|
||||
const delayedPromise = new Promise((resolve) => setTimeout(() => resolve('Finished'), 3000));
|
||||
const result = await timeoutWrap(delayedPromise, 1000);
|
||||
console.log(result);
|
||||
} catch (e) {
|
||||
console.error('Timeout occurred'); // Outputs: "Timeout occurred"
|
||||
}
|
||||
|
||||
// Using timeoutAndContinue
|
||||
const resultContinue = await timeoutAndContinue(
|
||||
new Promise((resolve) => setTimeout(() => resolve('Finished eventually'), 3000)),
|
||||
1000
|
||||
);
|
||||
console.log(resultContinue); // Outputs: null (since it didn't resolve in 1 second)
|
||||
|
||||
// Using Map
|
||||
const items = ['a', 'b', 'c'];
|
||||
const processedItems = await map(items, async (item) => {
|
||||
await new Promise((resolve) => setTimeout(resolve, 500));
|
||||
return item.toUpperCase();
|
||||
});
|
||||
console.log(processedItems); // Outputs: ['A', 'B', 'C']
|
||||
|
||||
// Using getFirstTrueOrFalse
|
||||
const raceResults = await getFirstTrueOrFalse([
|
||||
new Promise<boolean>((resolve) => setTimeout(() => resolve(false), 1000)),
|
||||
new Promise<boolean>((resolve) => setTimeout(() => resolve(true), 2000)),
|
||||
]);
|
||||
console.log(raceResults); // Outputs: true
|
||||
|
||||
console.log('Complete Use Case Example Finished!');
|
||||
}
|
||||
|
||||
completeUseCaseExample();
|
||||
```
|
||||
|
||||
### Testing Your Code
|
||||
|
||||
Testing is crucial to ensure the reliability of your asynchronous workflows. You can write tests using the `@push.rocks/tapbundle` library to create unit tests for your promises and deferred constructs.
|
||||
|
||||
```typescript
|
||||
import { tap, expect } from '@push.rocks/tapbundle';
|
||||
import * as smartpromise from '@push.rocks/smartpromise';
|
||||
|
||||
tap.test('should resolve a deferred promise', async () => {
|
||||
const deferred = smartpromise.defer<string>();
|
||||
deferred.resolve('Resolved!');
|
||||
const result = await deferred.promise;
|
||||
expect(result).toEqual('Resolved!');
|
||||
});
|
||||
|
||||
tap.test('should timeout a long-running promise', async () => {
|
||||
const longRunningPromise = new Promise((resolve) => setTimeout(resolve, 2000));
|
||||
try {
|
||||
await smartpromise.timeoutWrap(longRunningPromise, 1000);
|
||||
} catch (err) {
|
||||
expect(err.message).toEqual('timeout');
|
||||
}
|
||||
});
|
||||
|
||||
tap.test('should map async function to an array', async () => {
|
||||
const inputArray = ['a', 'b'];
|
||||
const result = await smartpromise.map(inputArray, async (item) => item.toUpperCase());
|
||||
expect(result).toEqual(['A', 'B']);
|
||||
});
|
||||
|
||||
tap.start();
|
||||
```
|
||||
|
||||
By following this guide and using the examples provided, you should be able to effectively use `@push.rocks/smartpromise` for managing promises and deferred constructs in your TypeScript project. The library's extensive utility functions, combined with TypeScript support, make it a powerful tool for modern asynchronous programming needs.
