Odd Promises

Library to do some odd things with promises

Installation

install using your package manager:

npm install odd-promises

OR for yarn

yarn add odd-promises

Examples

The following example shows how you can do some API calls but only wait for so long for a reply. The underlying promises are still resolved, so while the shown result is "Took to long", the actually promise that was prematurely resolved is still running in the background.

Takeaway only do this when the action's result isn't as important as the fact that it resolved.

const promises = toInteractivePromisesArray(
    someApiCall("test"), // will finish in 5000ms
    someApiCall("test 1"), // will finish in 5000ms
    someApiCall("test 2", 500) // will finish in 500ms
);

timeoutAt(1000, promises, "Took to long");
const result = await Promise.allSettled(getUnderlyingPromises(promises));

expect(result).toEqual([
    { status: "rejected", reason: "Took to long" }, // took longer than 1000ms
    { status: "rejected", reason: "Took to long" }, // took longer than 1000ms
    { status: "fulfilled", value: "test 2" }, // took less than 1000ms
]);

The following is a very basic example, in which we overwrite the result from the api call by prematurely resolving to "not test".

const interactivePromise = new InteractivePromise(someApiCall("test", 1000));
interactivePromise.resolve("not test");
const result = await interactivePromise.promise; // result === "not test";
