kandi X-RAY | cwait Summary

cwait is a TypeScript library typically used in Programming Style, Reactive Programming, Nodejs applications. cwait has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

[npm version] cwait provides a queue handler ([TaskQueue] #api-TaskQueue)) and a wrapper ([Task] #api-Task)) for promises, to limit how many are being resolved simultaneously. It can wrap any ES6-compatible promises. This allows for example limiting simultaneous downloads with minor changes to existing code. Just wrap your existing "download finished" promise and use it as before. This is a tiny library with a single dependency, usable both in browsers and Node.js.

QUESTION

Skip waiting if async function (Promise) is taking too much time

Asked 2021-May-11 at 15:35

In my express application, I am making call to 2 APIs. The 2nd API is managed by 3rd party and sometimes can take more than 5 seconds to respond. Hence, I want to just wait for 1 second for the API to respond. If it does not, just proceed with data from 1st API.

Below is the mock-up of the functions being called. I am thinking to use setTimeout to throw error if the API takes more than 1 second. If the API responds within 1 second then I just cancel the setTimeout and no error is ever thrown.

But there is problem with this approach:

setTimeout errors cannot be catched using try...catch block.

I cannot use axios's timeout option, as I still need to wait for the 2nd API to finish the processing and save the data in the DB. This will ofcourse, can happen later, when the 2nd API call finishes.

please note, this is not the answer as it was when it was accepted as I misread the question and failed to call saveInDB in a timed out situation

Promise.race seems perfect for the job

Also, you'd actually use your cWait function, not for mock-up, but to actually do something useful ... win the race :p

First, you asked a question about a failing solution attempt. That is called X/Y problem.

So in fact, as I understand your question, you want to delay some DB request.

You don't want to delay the resolving of a Promise created by a DB request... Like No! Don't try that! The promise wil resolve when the DB will return a result. It's a bad idea to interfere with that process.

I banged my head a while with the library you tried... But I could not do anything to solve your issue with it. So I came with the idea of just looping the data and setting some timeouts.

I made a runnable demo here: Delaying DB request in small batch

Here is the code. Notice that I simulated some data and a DB request. You will have to adapt it. You also will have to adjust the timeout delay. A full second certainly is too long.
