stack-promises
A stack of tasks that are executed one by one, but the result is taken from the last. Identical functions on the stack (check by reference) are executed only once.
Install
npm
npm install stack-promises
yarn
yarn add stack-promises
Usage
import creteStackPromises from 'stack-promises';
const stackPromises = creteStackPromises();
stackPromises.add(() => Promise.resolve(1));
stackPromises.add(() => Promise.resolve(2));
stackPromises().then(data => {
console.log(data); /// 2
});
Execute after add
import creteStackPromises from 'stack-promises';
const stackPromises = creteStackPromises();
stackPromises
.add(() => Promise.resolve(1))() // execute
.then(data => {
console.log(data); // 1
});
stackPromises
.add(() => Promise.resolve(2))() // execute
.then(data => {
console.log(data); // 2
});
stackPromises().then(data => {
console.log(data); // 2
});
Add after execute
import creteStackPromises, { isPromiseIsNotActualError } from 'stack-promises';
import delayPromise from 'promise-delay';
const stackPromises = creteStackPromises();
let checkQue = 0;
const request1 = () =>
delayPromise(3000, 1).finally(() => {
checkQue += 1;
});
const resultAfter1 = stackPromises.add(request1)();
const request2 = () =>
delayPromise(1000, 2).finally(() => {
checkQue *= 2;
});
const resultAfter2 = stackPromises.add(request2)();
Promise.allSettled([resultAfter1, resultAfter2]).then(([{ reason }, { value }]) => {
isPromiseIsNotActualError(reason); // true
value; // 2
checkQue; // 2
// request1 called 1 times
// request2 called 1 times
});
Chaining
stackPromises.add(() => Promise.resolve(1)).add(() => Promise.resolve(2));
