海外TECH	DEV Community	Upgrade to Yarn V3/Berry. But Why?	https://dev.to/raxraj/upgrade-to-yarn-v3berry-but-why-2cfo	Upgrade to Yarn V Berry But Why Yarn is a package manager that has gained popularity in the JavaScript community due to its speed reliability and ease of use It was initially released by Facebook in as an alternative to npm the default package manager for NodeJS From that point onwards it just kept growing Yarn has been a staple in the JavaScript community for years but it just outdid itself with the release of Yarn Berry It s like Yarn on steroids and it s packing some serious punches So why upgrade to Yarn Berry you ask Let s dive in What changed Let me tell you a little story about how Yarn Berry came to be It all started with one brave soul who decided to take on the pesky node modules directory You know that clunky beast that can get as heavy as a black hole in your project and suck it in if you re not careful Say goodbye to the old days of node modules with Yarn Berry Thanks to its global cache you can now enjoy faster and more efficient package installations without worrying about disk space or cluttered file systems Trust me It is fast Yarn v is like a superhero swooping in to save the day with its Berrylicious superfast speed Its new architecture and Plug n Play system But why trust me when you can look at it yourself I m gonna install dotenv express passport into my project folder for each of the package manager and after that I m just gonna run yarn install in both of these to see which runs faster Well that was fast only ms Way to go Yarn v It was only ms Less than half of v So to all the doubters out there I say this Trust me I know what I m talking about Don t let your trust issues get in the way of experiencing the magic of Yarn Berry What is even this Plug n Play Think of the Plug n Play system in Yarn berry like a shared pantry in a big office building Instead of every employee bringing in their own snacks and drinks and storing them in their individual cubicles there s a central pantry where everyone can access the same goodies This saves space in individual cubicles avoids duplicate snacks and makes it easier for everyone to find what they need without having to search through their own personal stash Similarly with Yarn berry instead of each project having its own pantry of packages in the node modules directory they all share the same pantry in the global cache This saves space on your computer avoids duplicate packages and makes it faster to install the packages you need for your project Does it really helps in minimising dependency collision In Yarn v workspaces are an important feature that allows you to work with multiple packages as if they were a single project This is particularly useful if you have a large codebase with many interdependent packages or if you re working on a monorepo With Yarn v you can define a workspace in your project s package json file which lists all the packages you want to work with Yarn will then link all these packages together so that you can work on them as if they were a single project One of the benefits of this approach is that you can share dependencies between packages For example if you have two packages that both depend on the same version of React you can define React as a dependency in your root package json file and then both packages will use the same version of React No more conflicts between package versions as Yarn v keeps everything in line like a drill sergeant Plus you ll have less duplication in your codebase as you only need to install each package once It s like decluttering your closet but for your project Cache Me If You Can Yarn v s Groovy Package Caching SystemYarn v comes with a new and improved caching system that makes package caching more efficient and effective than ever before The caching system is smarter and more optimised Yarn v s caching system is always up to date so you ll never feel like you re stuck in the past with outdated packages It s like having a personal package stylist that always keeps you on trend Yarn s Got It Together Improved Stability Yarn v also known as Berry is the result of years of experience and hard work With this new version the Yarn team has finally been able to fix longstanding design issues that had been plaguing the previous version known as Classic Thanks to a streamlined resolution pipeline improved data structures and the inclusion of workspaces as core components Yarn v is significantly less likely to suffer from incorrect assumptions and other design flaws In short Yarn v is a modern marvel that developers can rely on for stable and efficient package management ConclusionIn a nutshell upgrading to Yarn v Berry offers a wide range of benefits including improved performance workspace management and error reporting If these reasons don t sway you then I m not sure what will So don t be hesitant embrace the upgrade and experience the positive impact on your project s dependencies management Let s get groovy and upgrade to Yarn v Berry And as always Thanks for reading	2023-04-27 13:30:22
海外TECH	DEV Community	React Hooks: Exploring the power of `useEffect` Hook.	https://dev.to/ghostaram/react-hooks-exploring-the-power-of-useeffect-hook-b11	React Hooks Exploring the power of useEffect Hook Are you excited about learning React at a time when you don t need class components at all Well I am excited too because I would have had such a difficult time having to learn lifecycle methods like those componentDidSomething s We are learning at such an interesting time when the React team has gone through all possible troubles to introduce React hooks In this article we will talk about the useEffect Hook in particular and its role in React functional components The useEffect hook gives functional components a way to synchronize with external systems an operation that was originally possible only with class component lifecycle methods Without too much small talk let us get into the good stuff about the useEffect hook In order to use the useEffect hooks we need to import it from react using the line below import useEffect from react The useEffect hook is provided as a named export so we import it inside curly braces The useEffect hook can be used to perform various tasks including Binding event listeners fetching data from an external API removing event listeners making and canceling subscriptions and making network requests just to mention a few More of these tasks with deeper dives are available in the new react docs The syntax for calling useEffect hook is simple you need to call the useEffect function with the setup code and a dependencies array useEffect setupCode dependecyArray The parameter setupCode represents the code that performs a side effect and the dependencyArray represents and array of all props and or states that the side effect dependent on Depending on which tasks you need to run inside the hook and how often you want to cause there side effects the useEffect can be called in different ways We will discuss the options below beginning with calling the useEffect hook to run a side effect only once Running Side Effects only once after the Initial RenderSometimes you want to perform a particular side effect only once after the initial render and no more Such cases can be binding an event listener to an element in the DOM In order to run side effects only once after the initial render we call the useEffect hook with an empty dependency array useEffect gt window addEventListener mousemove logMousePosition return gt window removeEventListener mousemove logMousePosition In the code snippet the mousemove event listener is added to window once after the initial render Running Side Effects ConditionallyMore often than not we want to run perform side effect operations based on changes in the values of props or states or sometimes both In this case we need to tell React to observe specific variables for changes If any change occurs in the values the side effect is dependent on the setup code in the side effect is triggered In order to achieve this we call useEffect with a list of dependencies useEffect gt document title The count is count count This time the useEffect hook is called with a dependency inside the dependency array This means that the hook will always watch for changes in the value of the count variable and if its value changes the side document title is updated with the new value of count Running Sides Effects after every RenderTake for example you want to update and display the value of a particular variable on the screen after every second from the time of rendering to the time when the Component rendering that variable is removed from the DOM In this case you want the effect to be cause after every re render In order to achieve this behavior we call the useEffect hook with the code we want to run but we do not define the dependency array We do not define it all as in the code snippet below const tick counter gt setCounter gt counter console log call effect const interval setInterval gt tick counter This code snippet updates the value of count and renders it after an interval of microseconds This effect runs right after the first render and after all re renders Cleaning Up Side Effects with useEffectIn the above code snippets we have performed side effects and we are getting what we want Yes we are getting what we want but what happens to the side effects when we remove the component from the DOM Well this is where cleanup comes in play Every time a component is removed from the DOM we should also revert all its side effects Reverting side effects may include operations like canceling network requests removing event listeners canceling subscriptions removing timers ect Cleaning up side effects may be done by returning the cleanup code inside the useEffect function call as done in the code snippet below useEffect gt const tick counter gt setCounter gt counter console log call effect const interval setInterval gt tick counter return gt clearInterval interval This is the same code in the previous section but this time we are adding a cleanup code to clear interval when the component causing this effect is umounted removed from the DOM Keep in mind that the returned code runs only when the component firing the side effect is removed from the DOM That s all about useEffect hook for today look for more examples and practice If you are interested in diving deeper into this please consider looking into the docs from react team Happy learning	2023-04-27 13:29:54

海外TECH	DEV Community	Async Redux: Updating 2 Slices at Once	https://dev.to/dawnteigh/async-redux-updating-2-slices-at-once-1kca	Async Redux Updating Slices at Once    Allow me to paint a scenario you have a React application that connects to a relational database let s say you re using Ruby on Rails Active Record You are using asynchronous Redux with Thunk Check out Redux Toolkit to fetch data from three different models and save them into state The models and their relationships are as follows So would we need to create a slice for all three models in order to manage all of our state Well no Assuming that both a user and a movie are serialized to include an array of their reviews a reviewsSlice isn t necessary all of the reviews can be accessed and updated through association methods That leaves us needing one slice to handle the current user in the session hash sessionsSlice and another to manage the movies from the database moviesSlice Asynchronous action creator sends a GET request to your SessionsController in the back endexport const fetchUser createAsyncThunk sessions fetchUser gt return fetch your route for the current user then response gt response json then data gt data const sessionsSlice createSlice name sessions initialState currentUser status idle reducers extraReducers Dispatching fetchUser in the front end will run the pending action first then the fulfilled action when the response from the GET request comes back fetchUser pending state state status loading fetchUser fulfilled state action state currentUser action payload state status idle We can directly mutate state thanks to Immer included in the Redux Toolkit The code to get the movies will look very similar only the endpoint in the fetch and the initialState should differ and the name of the slice and async action but you knew that right Now when we access state we should be able to call currentUser reviews or reviews on any given movie and render accordingly We have all of our data in state and it only took two fetches But how do we update state in both slices whenever we create edit or delete a review Are we sending two POST requests Heck no The key is going to be writing additional actions to dispatch alongside your review related requests A review has both a user id and a movie id so it would make sense to at least have your create and update actions in the back end be through one of these associations Since the current user is the one performing these actions it makes the most sense to create and update using their id Thus we will be performing all of our asynchronous actions in sessionsSlice export const addReview createAsyncThunk reviews addReview reviewObj gt return fetch reviews method POST headers Content Type application json body JSON stringify reviewObj then r gt r json then data gt data this line gives us our action payload i e the new review Down in extraReducers addReview pending state state status loading addReview fulfilled state action state currentUser reviews push action payload state status idle You can see from the above code that we are passing in a reviewObj parameter for the body of the POST request This is simply the controlled form data from your review creating component and the id of the movie being reviewed const reviewObj movie id movie id from props content form content from controlled form rating form rating So if you can pass this object in when you dispatch addReview you can also use it to update the movie s reviews right Well let s see const moviesSlice createSlice name movies initialState entities array of movies status idle loading state reducers addMovieReview state action const movie state entities find m gt m id action payload movie id movie reviews push action payload And in the review form component const handleSubmit e gt e preventDefault dispatch addReview reviewObj dispatch addMovieReview reviewObj user id currentUser id brought in from the store And there you have it Both the user s reviews and the movie s reviews are updated with one click and Redux automatically rerenders the app to reflect the changes While this seems alright on the surface there is one glaring issue there is no accounting for failure If the review doesn t pass validations on the back end we get an error pushed into our user reviews and an invalid review attributed to our movie So how do we fix this We start by removing the second dispatch from our review form s handleSubmit There s nothing wrong with the addMovieReview action we just won t be calling it here Next we will be adding a few things in sessionsSlice error handling and some shiny new variables in initialState name sessions initialState currentUser review null for storing a new updated review instance errors to push error messages into status idle reducers We ll throw some new actions in here so we can update our new variables from the components setReview state action state review action payload setErrors state action state errors action payload extraReducers addReview pending state state status loading addReview fulfilled state action Here we conditionally handle the error key that we return from the back end should it show up in our response if action payload error state errors action payload error state status idle else If the payload does not contain the error key we can add the new review to the user object in state and store it inside of our new review variable as well state currentUser reviews push action payload state review action payload state status idle The two new variables can now be used in combination with the useEffect hook at our app s top level component The errors variable can be used to inform the user should their request go awry I like to use a pop up or overlay to render the errors with a dismiss or x button that can dispatch setErrors on click but you could also opt to reset the errors inside of addReview fulfilled after a successful post is made More importantly we can now finally add our new review to its respective movie Behold App jsconst review useSelector state gt state sessions review useEffect gt if review dispatch addMovieReview review dispatch setReview null Here you can programmatically navigate to another page or anything else you want to do after a review is created review So for a quick rundown The user submits a new review dispatching the addReview action in sessionsSliceIf the review clears validations it is added into state in sessions currentUser reviews and stored in sessions reviewThe review variable is pulled from state in the application s top level component triggering a useEffect the second it becomes a truthy value i e the new review instance The useEffect dispatches two actions one to add the new review to the corresponding movie and the other to reset the review variable to nullAnd there you have it Two slices of state updated with a single click though there s a lot more going on behind the scenes This same flow can be applied to update and destroy actions as well with the use of the review in question s id See if you can get it figured out on your own or check out the Redux Toolkit documentation where there s certain to be a way better solution that I overlooked You ve got this Shoot if you made it through this roller coaster of a blog there s probably nothing you can t do	2023-04-27

海外TECH	DEV Community	Blockchain: Understanding basics	https://dev.to/pvishnuprasaath/blockchain-understanding-basics-5hda	Blockchain Understanding basicsIn this article let s try to demystify and understand the basics of the blockchain infrastructure and see how it contributes to the web ecosystem What is a blockchain Basically blockchain is a Data Structure Very similar to other data structures like databases rows columns tables text files CSV images lists and so on Blockchain competes most closely with a database For an analogy let s visualize blockchain as pages in a bookChain BookBlock PageBlocks in Chain Pages in BookEach page in a book contains text content storyinformation about the page chapter number title page numberSimilarly in a blockchain block each block has contents of the block Transaction details in cryptocurrency or any data which we prefer to storeheader Metadata data about the block Some sort of technical info about the block a reference to the previous block and a fingerprint hash of the data for the current blockIn blockchains each block references the previous block by a computed hash value called the blocks fingerprint The fingerprint is computed based on the contents of the block The concept of maintaining a reference to the previous blocks can be visualized as a linked list structure In the linked list each node holds a reference to the next node whereas in the blockchain each block holds a reference to the previous block This creates the fancy structure called the blockchain The fingerprint in each block is responsible for taking care of the consistency and validity of the data If someone tries to meddle with any of the data they have to end up regenerating all the fingerprints from that point forwards and the blockchain will look different This is basically impossible as the process of creating fingerprints is difficult and slow Therefore if someone wants to re write parts of the blockchain it will take them a long time and they have to catch up with and overtake the rest of the honest network Which is not feasible Hence the blockchain is called immutable as it cannot be changed The below image shows the inside of a blockchain block the fingerprints are unique to the blocks contents Data DistributionThere are two ways of distributing data in a network Client Server and Peer to peer Blockchain is built on top of the peer to peer model Client serverThis is a traditional approach where the server holds of the data and the clients connect via required protocols to access consume the data Peer to peerIn peer to peer models each peer has of the data or as close to it as possible and updates are shared around This is less efficient than client server as data is replicated many times However it s more robust as there is no central server that can be controlled so closing down peer to peer networks is harder But on the contrary the peer to peer model comes with its downsides In the real world each peer on the network is gonna process and update at its own speed and latency and end up having varied states at a given timestamp Deciding on which peer holds the valid data and which peer has stale or tampered data is ambiguous This conflict is resolved by a rule called the longest chain rule If you see multiple blocks treat the longest chain as legitimate We can discuss in depth on this conflict resolution and consensus in a separate article ConclusionBlockchain is not something that is associated with only Bitcoin Ethereum is a great variant of blockchain with smart contracts There are significant challenges involved On the other hand private or internally distributed ledgers and blockchains can be deployed to solve a wide range of problems and use cases	2023-04-27 13:05:31

海外TECH	Engadget	The best WiFi extenders in 2023	https://www.engadget.com/best-wifi-extender-130021313.html?src=rss	The best WiFi extenders in A reliable home internet connection has never been more important Many of us work from home part time or full time now and others increasingly have more of their home powered by smart devices Also we all just have more connected devices in general ーphones tablets consoles TVs and more In setting up and maintaining all of your tech you might have discovered you have a dead spot or a weaker WiFi signal in your garage than the rest of your home or spotty coverage in your makeshift home office And depending on the size of your abode your WiFi s strength might be abysmal on its outskirts This is where WiFi extenders come in These relatively affordable gadgets as their name suggests extend your home network to provide more widespread coverage These devices can give you connectivity in places you may have never had it before like garages backyards and the farthest corners of your property And they won t cost you a fortune like many of the latest mesh network systems you ll find today Let s break down how these gadgets work what you should consider before picking one up and the best WiFi extenders we tested How do WiFi extenders work These handy devices do exactly what their name suggests extend your WiFi network so it covers more areas of your home Most WiFi extenders plug into an AC outlet and connect to your existing network so they can then rebroadcast it to spots that your router alone may not cover well As a rule of thumb you ll get the best results by placing the extender half way between your router and the dead zone you re trying to fix One important thing to note about WiFi extenders also sometimes called “repeaters is that most of them actually create a new WiFi network when rebroadcasting your existing one That network will have a new name it ll often be your default network s name with an EXT appended at the end unless you change it and that means you ll have to connect to different networks when in different parts of your home While that s a small tradeoff in return for improved coverage some will be more inconvenienced than others If you d rather have one much larger network in your home you re better off upgrading to mesh WiFi Mesh systems come with a main router and access points that by default create one large WiFi network that should be accessible throughout your entire home But that also translates to more expensive and possibly more complicated devices Mesh systems are by far more costly than a simple WiFi extender plus you may have to work with your ISP to get your home s existing network working on your new router What to look for in a WiFi extenderSpeedExtenders today can support single dual or tri band WiFi and they will tell you the maximum speeds they support on all of their available bands For example one dual band device might support Mbps speeds over its GHz band and up to Mbps over its GHz band for a combined maximum speed of Mbps For the best performance you ll want to go with a WiFi extender that has the highest speeds possible and those as you might expect tend to cost more However it s important to remember that WiFi extenders are not designed to increase speeds across your home In fact you may find that the extender s network is slower than your router s Instead extenders are designed to increase the WiFi coverage throughout your home making them ideal for filling in dead zones Range and number of supported devicesWith the name of the gaming being coverage area taking note of a device s range is important Depending on the size of your home and property you may only need up to square feet of coverage But those with larger homes will want to spring for an extender that can support upwards of square feet of coverage Similarly those with lots of gadgets will want an extender that can handle them all at once If you spend most of your time on your phone or laptop and maybe have your smart TV online for a few hours each day you could get by with a more limited extender Smart home aficionados and tech lovers should invest in one that won t buckle under the pressure of a few dozen connected devices This is especially important if you plan on linking all of the devices in a certain part of your home to your extender s network rather than directly to your router DesignThere isn t a ton of innovation when it comes to design in the WiFi extender space Most of the ones you ll find today are rounded rectangles roughly the size of your hand that plug into a standard AC outlet They usually have a few indicator lights that will show you when the extender is connected how strong its signal strength is and when there s a problem and some will even have moveable antennas that companies claim provide even better WiFi coverage Aside from that there are the scant few standalone WiFi extenders that sit on an end table or a desk and those look pretty similar to regular ol routers But make no mistake anything labeled as an extender or a “repeater will need an anchor router in order for it to work Another convenient feature you ll find on most WiFi extenders is an extra Ethernet port or a few This allows you to use the extender as a WiFi access point if you connect it to your router or an adapter to provide devices like TVs smart home hubs or game consoles a hardwired connection to the internet Unsurprisingly this wired connection usually provides you with the fastest speeds possible so you may want to use it for your most crucial devices Engadget picksBest for most TP Link AX WiFi extender REX or REX TP Link has a bunch of WiFi extenders under its umbrella but the one that will likely serve most people the best is this AX model which comes in two variations the REX and the REX Both extenders have the same specs including WiFi support but the X has a slightly different design with pull out antennas on either side I tested the X so I m basing my recommendation off of my experience with that model specifically Setting up this extender was as easy as plugging it in and following instructions in TP Link s Tether mobile app All of the devices I tried followed the same basic setup process first plug the extender in close to your router follow instructions in a mobile app or on a setup webpage and once the connection is established move the extender to your desired location It took all of five minutes to pair the X with my Verizon FiOS router probably the most time consuming bit was deciding what I wanted to name the new Ghz and Ghz networks I went with the same name for both because I didn t want to manually choose from two different bands when connecting things like my phone or laptop The device will automatically pair your device with the appropriate band ーfor example connecting most smart home gadgets to the Ghz network The permanent location where I moved all of the extenders I tested was in my basement since that s where we can get the spottiest signal I first ran speed tests on my iPhone and MacBook using Speedtest net and Speedcheck org so I could compare them with the standard speeds I got when connected to my router s main network Unsurprisingly the speeds generated by TP Link s extender were much slower than those from my router s network but that was the case with all of the devices I tested Only our premium pick see below got close to my router s standard speeds but I expected this WiFi extenders aren t going to make your connection better they re just going to give you a wider area of coverage From a spec perspective both the X and the X are rated for speeds up to Mbps on the GHz band and Mbps on GHz band Despite the results of my tests I was happy to discover that I wasn t held back by the X s seemingly slower speeds I worked as normal for hours with my phone and laptop connected to the extenders network answering emails messaging in Slack streaming YouTube videos and otherwise maintaining a few dozen tabs in Chrome without any hiccups or noticeable slow downs I was not surprised to find TP Link s Tether companion app to be easy to use if a little simple because that was my experience with TP Link s smart home app Tether is specifically used with the company s networking devices and you probably won t spend a ton of time in it after initial setup I especially like that you can name devices that are connected to your extenders network like your phone and smart TV That makes it much easier to know which things in your home are constantly paired with the extender rather than your router s default network One important thing to note with these TP Link extenders is that they both support OneMesh which is the company s feature that allows you to create one seamless mesh network if you have a compatible router Since I m still using the router provided to me by my ISP I wasn t able to test out this feature but it works like this if you have a OneMesh router and OneMesh compatible extenders you can link them all together under the same network name So rather than having a router network and an extender network under the same roof everything would be linked and filed under your main network s name It s a small perk that becomes not so small if you have a spotty extender or even just an awkwardly laid out home In my testing I found my phone disconnecting from some extenders networks when I went upstairs to the main floor of the house from my basement It would then attempt to reconnect to the extender network when really I would have preferred it to default back to my router s network That thankfully didn t happen with TP Link s REX but it s something to keep in mind when considering buying a WiFi extender at all If you can get one that has a feature like OneMesh it ll make your life much easier Coming in at and respectively the REX and REX may not be the cheapest WiFi extenders out there but their coverage range WiFi support and max speeds make either of them a good pick If you know exactly where you want to put an extender and it s not in an awkward or hard to reach location the slightly cheaper antenna free REX may work just fine for you But if you want that extra ability to tweak antennas to suit your needs the REX is the way to go Best budget TP Link AC WiFi extender RE TP Link s RE WiFi extender is physically very similar to the REX but with lower specs and that s what makes it a device You ll get up to Mbps speeds on the GHz band and Mbps on the GHz band and it only provides coverage for up to square feet That won t be as much of an issue for most people as max speeds will but if you have a particularly large property you re better off going with a more expensive extender that can cover more space There s also no WiFi support on the RE which may be a dealbreaker for those who recently invested in a WiFi router This model does support OneMesh though which is nice if you already have a OneMesh system in your home I m focusing on specification differences because my experience with the RE wasn t that far off from the REX Setup was just as plain and simple since the RE also uses the Tether mobile app and while speeds were slightly lower in my testing I didn t notice too much of a difference in real world use For normally and often closer to when on sale the RE is an easy pick for anyone who wants a budget friendly way to fill WiFi dead zones in their home Best premium Netgear AX WiFi mesh range extender EAX Having more than one WiFi network in your house is par for the course when it comes to adding an extender into the mix But that s not so with the Netgear EAX mesh range extender it has “seamless smart roaming which allows you to set it up under your existing SSID name So instead of disconnecting from your main network and reconnecting to the extender s network when you move from your living room to your basement all you have to do is…move from one room to another and let Netgear s device do the heavy lifting That s one of the premium features included on the EAX but its price tag can be attributed more so to some other perks It s a dual band WiFi mesh range extender that will work with pretty much any router you may have It supports speeds up to Gbps and can have more than devices connected to it at once As far as square footage goes it ll widen your WiFi s coverage by up to square feet which should be plenty for small and medium sized homes It performed well in our speed tests coming very close to the upload download speeds I got when being connected to my main network before installing the extender There s nothing out of the ordinary about the Nighthawk mobile app which is what you ll use to initially set up the EAX extender After that you can use the app to troubleshoot check WiFi speeds and see which devices are on your network It ll likely be a big list since you ll see everything that s paired to your router s network as well My only gripe is that you can t edit device names For example my den s TV shows up as “LGwebOSTV and our soundbar in our basement shows up as “sonyaudio ーbut there are a number of connected devices with no name at all and we re just stuck with that Aside from its fast speeds and reliable connection two things set this Netgear extender apart from the other devices I tested First is that seamless smart roaming feature not having to switch between WiFi networks when going around my home was super convenient I never had to worry about my laptop losing connection to a dedicated extender network when I moved from my basement to my second floor which is something I frequently had to deal with when testing other devices The second differentiating factor is the EAX s design Unlike other range extenders that are chunky blocks that plug directly into an AC outlet Netgear s model looks more like a standalone router While that does mean it has a larger footprint than other devices I tested it was actually easier to find good spots for it in my home because it didn t have to be chained to the wall right above an outlet Most people especially those tight on space will probably prefer the standard extender design but the EAX gave me a bit more flexibility I also appreciated that the EAX has four built in Ethernet ports for physically connecting things like TVs consoles and more plus one USB A port for hardwiring a printer Netgear s EAX range extender is a solid option if you don t mind dropping a bit of money to get a bunch of convenient features on top of stellar speeds and WiFi support But it s worth noting that Netgear has a few options that are similar to the EAX but with various differences in speed coverage and feature set The most similar is the EAX extender which includes square feet of coverage support for WiFi and up to Gbps speeds plus seamless smart roaming capabilities The wall plug version of that the EAX is actually a tad more expensive
