海外TECH	DEV Community	RxJS pipe as a React hook	https://dev.to/kosich/rxjs-pipe-as-a-react-hook-3lne	RxJS pipe as a React hookEver tried to use an Rx Observable in React Then you know what s the problem with this code function App let time setTime useState timer pipe filter x gt x map x gt x subscribe setTime return lt h gt time lt h gt Yeah it subscribes to the timer with each render Which happens on each timer emission Which leads to a re render Which leads to well you know memory leaks and weird behaviour And on top of that it won t be destroyed with the component unmount In this short post I want to share with you a non canonical idea probably not original one how to fix that tl dr online playground with hook pipe 🪝The hookWe could devise a custom react hook that will fix that Lets use a useEffect hook which will subscribe to the source and push messages to our observer setTime in the example above let useObservable observable observer gt useEffect with empty deps will call this only once useEffect gt let sub observable subscribe observer connect return gt sub unsubscribe lt unsub on unmount And it will be used like this function App let time setTime useState useObservable timer pipe filter x gt x map x gt x setTime return lt h gt time lt h gt Which looks react ish but not rx ish Not nice We can do better So let s explore another way ️RxJS pipesBut before we continue a quick reminder of RxJS pipe operator mechanics Roughly speaking RxJS pipe operator like map is just a function that takes one Observable and returns a new Observable source Observable lt A gt gt Observable lt B gt So when we subscribe to the resulting Observable lt B gt operator subscribes to the source Observable lt A gt And when that source emits a value operator applies its logic to it map filter etc and decides what when and how to push to the resulting Observable lt B gt map will push modified values filter will push only values that satisfy given condition Okay back to hooks 🪝️The hook pipeWe can modify the hook to implement the Rx Operator interface while still enclosing a useEffect hook Let s start with how we ll use it in a component function App let time setTime useState timer pipe filter x gt x map x gt x useUntilUnmount subscribe setTime return lt h gt time lt h gt And here s it s implementation function useUntilUnmount Observable gt Observable interface return source gt new Observable observer gt create a new Subscription we ll use it to handle un mounts and unsubscriptions let sub new Subscription this is run only once useEffect gt connect observer to source sub add source subscribe observer on unmount destroy this subscription return gt sub unsubscribe return sub to handle un subscriptions return sub This is really just lines of code Disclaimer while being leak free and working as promised this might not be the best way to use Observables in React Tried lt gt fragment already OutroTry our shiny hook pipe with dependencies in this online playground and leave a comment here with your opinion And in the future when pipeline operator gt lands in JS we ll probably substitute the subscribe with our custom hook subscribe Like this function App let time setTime useState timer gt filter x gt x gt map x gt x gt subscribeHook setTime return lt h gt time lt h gt That s it for today Follow me here and on twitter for more RxJS React and JS posts I hope you had fun If you enjoyed reading ーplease indicate that with ️buttons ーit helps a lot Thank you for reading this article Stay reactive and have a nice day Cya Psst Check out my other Rx React articles Fetching Data in React with RxJS and lt gt fragment Turn a Stream of Objects into an Object of Streams Queries for Observables Crazy amp Simple Intro to Recks Rx JSX experiment header image by Victor Garcia on Unsplash gif taken from giphy com	2021-04-26 17:34:36
海外TECH	DEV Community	Beginners guide to async-await in Javascript	https://dev.to/a_shokn/beginners-guide-to-async-await-in-javascript-33k8	Beginners guide to async await in JavascriptAsync Await is syntactical sugar wrapped around to make the implementation of promises easier If you don t understand how promises works make sure you check out this post The purpose of async await is to simplify the syntax necessary to consume promise based APIs Let s jump into an example that will help us understand Async Await in a better way function newRequest place return new Promise resolve reject gt if place home resolve You have reached home else resolve You haven t reached home function makeRequest response return new Promise resolve reject gt console log response resolve Current location response newRequest home then response gt return makeRequest response then makeResponse gt console log makeResponse catch err gt console log err Output You have reached home Current location You have reached home In the above example the newRequest function returns a promise that takes a parameter place based on which promise is resolved The makeRequest function returns a promise which is always resolved The two functions are executed in order the second promise waits for the first one The above code can be simplified by with the use of Async Awaitfunction newRequest place return new Promise resolve reject gt if place home resolve You have reached home else resolve You haven t reached home function makeRequest response return new Promise resolve reject gt console log response resolve Current location response async function checkLocation try const response await newRequest home const processed await makeRequest response console log processed catch err console log err checkLocation OUTPUT You have reached home Current location You have reached home In this example checkLocation is declared using the async keyword The async keyword tells javascript that the following function is asynchronous The checkLocation works exactly the same as the promises returning the same output As you can see it looks a lot better and readable than the first example Error handling is done with the help of a try catch block Async Await is just like promises in a way makes it easier to write promises Thank for your time	2021-04-26 17:05:04
