海外TECH	DEV Community	React Pro Tip #1 - Name your `useEffect`!	https://dev.to/deckstar/react-pro-tip-1-name-your-useeffect-54ck	React Pro Tip Name your useEffect There s a very simple trick that will x your useEffect hooks readability and probably improve their performance too use named functions as callbacks for your useEffects You might even find that you don t need an effect at all Contents TLDRBackstoryDrawbacksFurther reading TLDR Do this useEffect function doSomethingAfterMounting lt name me Your effect code Not this useEffect gt Your effect code Note that this may or may not make sense to you in months time What for This should provide key benefits More clarity in the purpose of the effect so other programmers would could easily tell what it s supposed to do just by reading the name If the effect throws an error the function s name will show up in the stack trace which should help debugging It should psychologically nudge the programmer into trying to make the effect do only one thing and to split different tasks into several useEffects if necessary But before you even write a useEffect consider if you even need one There are plenty of situations where using props directly or another hook like useMemo may make much more sense BackstoryuseEffect can be a dangerous hook if you don t know what you re doing Doubly so because it s usually opaque with little indication of intent I can t count how many times I ve stared at a giant useEffect with no idea what it was written to do or what its authors were thinking Once upon a time I had to refactor a huge amount of logic for a form page The original author had used useEffect in exactly the way that React doesn t recommend for updating state based on new props for caching for initializing field values for fetching data from an API and other bad practices Even worse he had often written all of that functionality into just one useEffect Clearly someone had never heard of useMemo There were several useEffects that stretched to lines or more Worse yet there were often several of them in one file each of which had its own setState calls that made the effects dependent on each other One file had such useEffects which side note is almost certainly far far too much code for any single component And alas that was not the end of it It turned out that these bad practices were littered throughout the website on code written by several programmers over many months The refactoring took a week and while it s nice to have some stable work to do I m pretty sure both I and the client would ve preferred if I had been doing something more productive It was around that time that I realized that not only is useEffect is very easy to abuse but that probably the worst part of it was how opaque it was I was reading Bob Martin s Clean Code around this time and noticed that this gentleman had some pretty nice tips Among other pearls of wisdom he advised that all variables and functions should have a clear informative name functions should be small and short aim to do one thing have no side effects have minimal or no repetition and should have separated error handlingthe best comment is no comment at all ーyour code should be self explanatory in its intention through its concise logic and good namingIt was obvious to anyone with eyes that these principles were being woefully neglected in our client s codebase So as I did my rewrites I aimed to break up the enormous components with multiple useEffects into smaller easily understandable parts One file could turn into two or five or even ten This meant having to figure out what all of those giant effects actually did ーand to do that I often pulled out big chunks of logic into their own shorter functions fetch effects got their own functions as did moveUI openModal reorderList and many others It turned out that many of these things didn t even need to be effects and were thus eliminated But other things needed to stay as effects ーthings like autoClose or setHasMounted and I wanted to find a way for these effect hooks to also have names I aspired to code in a way so that even a person who didn t know how to program or at least didn t know JavaScript could see a name and instantly know the point of those few lines Comments wouldn t do so I started out with the simple idea of using a memoized callback that would get automatically called whenever its dependencies changed Idea using a named useCallback to add clarity to useEffect don t do this const doSomethingInAnEffect useCallback gt The effect code useEffect gt doSomethingInAnEffect doSomethingInAnEffect This definitely made things better The effects finally had a meaning even if they required this superfluous use of a memoized function It was at that point that one day it just struck me like a lightbulb if all I need is a name why not just use an old fashioned named function instead of an arrow function It seemed so simple and why not We never needed to use this inside the effect And then we could avoid the new useCallback hell that was festering Could it really be so simple I turned to Google and as it turns out I wasn t the first person with the idea see the sources below And if it s on Twitter it must be a great idea right Idea just using an old fashioned named function DO do this useEffect function doSomething insert effect in here lt notice no extra dependencies As I tried to name my effects I realized that their names weren t always so obvious ーand usually this was because one effect was trying to do too many things Once I realized this it became natural to split things apart until each effect did just one thing or just got removed completely and our code quickly got more clearer and simpler as a result Who knew that naming things well would turn out to be a gift that keeps gift on giving And so since then I ve always used named functions whenever I needed useEffect and I advise everyone else to do so too I don t blame my colleagues whom I also call my friends for writing messy useEffects I ve written plenty of unmaintainable code too haven t we all Plus back in those days we didn t have awesome guidance articles like You Might Not Need an Effect which I very much recommend you to read by the way I d also argue that we had inherited the psychological burden of only having one place for effects ーnamely componentDidUpdate ーfrom back in the days when we only had class components and this may have nudged us into a write a giant effect that handles everything state of mind that was didn t always shake off naturally So what have we learned I d say that this experience taught me a few lessons Make sure to keep your functions as short as possible Ideally they should do one thing This tip includes React components too If you need to render a giant form it s probably better to split it up into different files for each section and maybe even each field useEffect shouldn t be treated as a go to solution and can be dangerous if you don t know what you re doing To avoid hurting your app s performance consider if you can get by with just using the prop itself or with using useMemo and useCallback And finally while naming things may be one of the only two hard things in computer science it is absolutely vital for the readability of your code Which is why you absolutely must name all of your useEffects with named functions Drawbacks Are there even any So far I haven t had any issues with this method but have certainly felt the benefits One issue I can imagine occurring is pointer mismatches if you use the this keyword in your effect Recall that arrow functions do not have their own this but rather use their parent s this That said I have never ever seen this being used in an effect or in fact at all in a functional component so I guess it s a non issue ConclusionFrom what I can see we should all switch to using named functions in useEffect and should do so immediately This should make our code cleaner and more reliable and doesn t seem to have any drawbacks Not only would a simple name let everyone know your intentions but it should push you to write short do only one thing effects too What do you think Let me know in the comments And thanks for reading Further reading Sergio Xalambrí Pro Tip Name your useEffect functionsCory House Twitter thread about named
