海外TECH DEV Community Speed up your code with Promise.all https://dev.to/dperrymorrow/speed-up-your-code-with-promiseall-3d4i Speed up your code with Promise allSo one of the things I see commented on all the time in Javascript code reviews Say you have some code as such async function myFunction await someThing await someOtherThing await yetAnotherThing Do we need to each of these one at a time Cant we fork this and call them all together What being pointed out here is that we have to wait on each one of these Promises to return before the next one can start One of the most amazing things about working with Javascript is its concurrency Meaning it can run your code in parallel instead of waiting for each Promise to finish before moving starting the next Commonly referred to as forking Using Promise all vs await eachSince this ability is so powerful lets make sure we are using it Let s take a look at the example above and see how we can make that run in parallel function delayedResponse return new Promise resolve reject gt setTimeout resolve async function time label fn const start new Date await fn console log new Date start seconds to load label time sequential async gt await delayedResponse await delayedResponse await delayedResponse time parallel async gt await Promise all delayedResponse delayedResponse delayedResponse Ok here is some code that we can test this idea with I have a function that returns a Promise that takes sec to resolve function delayedResponse return new Promise resolve reject gt setTimeout resolve and a function that times how long a function passed to it takes to run async function time label fn const start new Date await fn console log new Date start seconds to load label These are not important I just wanted to explain what they were The main thing that we are talking about here is the difference in speed with the two approaches we are timing here Ok lets run this code and see what happens seconds to load parallel seconds to load sequentialWhoah that s almost times as fast for the parallel one Makes sense as there are three calls and each one takes a second You can see how this would greatly effect your performance if you had many Promises to wait on Say for example we had calls instead of What would the timing on that look like seconds to load parallel seconds to load sequentialYou guessed it twice as much on the difference Real world exampleSay for example you have a front end app that makes a few API requests before it s ready to render and become interactive This could make a HUGE difference to your users Capturing the responsesOne of the common excuses I have seen for awaiting each Promise is that But I need to save each response from each Promiseasync function const myData await someApiCall do something with your data You can still do that with Promise all Promise all returns the results in an Array in the order that the Promises were invoked not in the order that they resolve This is a common misconception Ok lets test this idea function randomDuration const min const max return Math random max min min function delayedResponse msg return new Promise resolve reject gt setTimeout resolve randomDuration msg done async function time label fn const start new Date await fn console log new Date start seconds to load label the code we are benchmarkingasync function sequential const res await delayedResponse first const res await delayedResponse second const res await delayedResponse third console log res res res async function parallel const results await Promise all delayedResponse first delayedResponse second delayedResponse third console log results time sequential sequential time parallel parallel Ok the main difference here is that I am giving each Promise a random duration before it returns between and second That way I can show that they come back in the order invoked not the order resolved first done second done third done seconds to load parallel first done second done third done seconds to load sequentialNotice that even though I randomized how long each Promise will take to resolve the results array is in the order that I called them in Fantastic Example where this won t workThere are some cases where you cannot call all your promises at the same time Take for example API calls like I mentioned above Say you need part of the result from one before you can call the next For example say you are using REST routes that are nested javascriptasync function const user await Api getUser const account await Api getAccount user id const articles await Api getArticles user id Well you cant call all these together but you may be able to still group some Just do the best you can javascriptasync function const user await Api getUser const account articles await Promise all Api getAccount user id Api getArticles user id Promise all vs Promise allSettledOne very important thing to note If ANY of the promises reject Promise all will reject at the first failure Think of it as fail fast If you need to handle each rejection and need a response for every Promise no matter what happens use Promise allSettled instead of Promise all 2022-11-23 21:15:15
