海外TECH	DEV Community	Building a CRUD app with Material UI and Strapi	https://dev.to/pankod/building-a-crud-app-with-material-ui-and-strapi-5gcn	Building a CRUD app with Material UI and Strapi IntroductionWe will build an admin panel that supports CRUD operations has built in authentication and a mutation mode feature using industry standard best tools Industry standard tools and practices can be hard to reach and time consuming to maintain on your own Frameworks can save you time by doing these jobs for you So we ll use powerful frameworks including Material UI Strapi and refine to build a high quality admin panel UI design can be a complex and time consuming process but a tool like Material UI can help simplify the process and speed up the development cycle In this tutorial we ll use Material UI s benefits and handle data fetching and mutations We ll also integrate the Strapi data provider that Refine has built in support We ll walk through the process of listing creating and deleting posts in a refine application and make use of refine s components and hooks to build out our functionality Steps we ll cover includes What are the benefits of using refine Bootstrapping the refine appImplementing Strapi v data providerCRUD operationsListing recordsAdding resources and connect pages to refine appHandling relational dataCreating a recordEditing a recordDeleting a recordImplementing mutation modeSharing the current page with filtersConclusionLive StackBlitz Example PrerequisitiesBefore we dive into the meat of the article let s first take a look at the tools documents we ll be using refinerefine StrapiV data provider Material UIrefine Material UI TutorialYour node version need to be mininum v What are the benefits of using refine refine is a headless React internal tool framework that helps you develop quickly while developing both BB and BC applications It speeds you up while allowing full customization making it an ideal choice for rapid development with pro features It is Open Source under the MIT license It is easy to use and learn There are many examples to help you get started as well as documentation Is a framework that does not require you to use any UI libraries or frameworks Supports Ant Design and Material UI natively for quick and easy solutions Thanks to the headless approach you can easily integrate your own UI solution Backend agnostic so you can connect to any backend you want Customizable which means you can change it to fit your needs Some of the main features are data fetching and state management routings authentication authorization internationalization real time mutation modes with optimistic and pessimistic and undoable modes Bootstrapping the refine appWe ll use superplate CLI wizard to create and customize refine application Run the following commandnpx superplate cli p refine react material ui exampleSelect the following options to complete CLI wizard Do you want to use a UI Framework ❯Material UI Do you want an extended theme ❯No Do you want to add dark mode support ❯No Router Provider ❯React Router v Data Provider ❯Strapi v Do you want a customized layout ❯No in Internationalization ❯NoCLI should be create a project and install the selected dependencies Implementing Strapi v data providerData providers are refine hooks making it possible to consume different API s and data services conveniently The required Strapi data provider setups are added automatically by the CLI wizard To consume refine s Fake Strapi API we ll need to change the API URL in the project folder src constants tsexport const API URL Refer to refine docs for more detailed information about refine Strapi V support→Refer to refine s data provider documentation for detailed information→Refer to official Strapi v documentation→ CRUD operationsWe are going to implement CRUD operations features like listing creating and editing records Listing recordsWe need to create PostList page to show data on the UI First we ll need an interface to work with the data from the API endpoint We ll create a new folder named interfaces under src if you don t already have one Then create a index d ts file with the following code src interfaces index d tsexport interface ICategory id number title string export interface IPost id number title string content string status published draft rejected category ICategory createdAt string Now we ll create a new folder named pages posts under src Under that folder create a list tsx file with the following code src pages posts list tsximport React from react import useDataGrid DataGrid GridColumns DateField List from pankod refine mui import IPost from interfaces export const PostList React FC gt const dataGridProps useDataGrid lt IPost gt const columns React useMemo lt GridColumns lt IPost gt gt gt field title headerName Title flex minWidth field createdAt headerName CreatedAt minWidth renderCell function render row return lt DateField format LLL value row createdAt gt return lt List gt lt DataGrid dataGridProps columns columns autoHeight gt lt List gt We import and use Material UI components from refine s pankod refine mui to show data lt DataGrid gt is a native Material UI component It renders records row by row as a table lt DataGrid gt expects a columns prop as a required refine hook useDataGrid fetches data from API and wraps them with various helper hooks required for the lt DataGrid gt component Data interaction functions like sorting filtering and pagination will be instantly available on the lt DataGrid gt with this single line of code Refer to refine s useDataGrid hook docs to more information→columns array are used for mapping and formatting each field shown on the lt DataGrid gt field prop maps the field to a matching key from the API response renderCell prop is used to choose the appropriate Field component for the given data type Info The useDataGrid hook works in compatible with both the lt DataGrid gt and the lt DataGridPro gt component Note you will need src App tsx file to find your pages and posts In the pages folder put this index tsx file in it which allows everything in the posts folder to be used elsewhere src pages posts index tsxexport from list Refer to offical refine s Material UI tutorial for detailed explanations and examples→ Adding resources and connect pages to refine appNow we are ready to start connecting to our API by adding a resource to our application We ll add posts endpoint from our example API as a resource We ll add the highlighted code to our App tsx to connect to the endpoint and List page App tsximport Refine from pankod refine core import notificationProvider RefineSnackbarProvider CssBaseline GlobalStyles

complete navigate to the project folder and start your project with npm run devThe application should redirect now to an URL defined by the name property It ll ask you to login to the app Try with these credentials Username demo refine devPassword demodemoCheck that the URL is routed to posts and posts are displayed correctly in a table structure and even the pagination works out of the box Handling relational dataRelations are not populated when fetching entries We ll use metaData option to use relational population for Strapi v API The records from posts endpoint that had a category id field To get category titles automatically from categories endpoint for each record and show on our table we need to use populate feature of Strapi v We ll set populate parameter to define which fields will be populated src pages post list tsx const dataGridProps useDataGrid lt IPost gt gt metaData populate category lt To show category field in table we need to add new column to the PostList component src pages post list tsx const columns React useMemo lt GridColumns lt IPost gt gt gt gt field category title headerName Category minWidth flex renderCell function render row return row category title lt Tip We use benefits of Strapi V relational population feature by using populate parameter It handles to getting relational data automatically If you use another REST API that relational populations need to be handled manually you can check the example at the link→Refer to refine Strapi v documentation for more information Creating a recordThe Material UI provides already styled but still very customizable inputs that encapsulate adding labels and error handling with helper texts However we need a third party library to handle forms when using Material UI React Hook Form is one of the best options for this job The React Hook Form library has been integrated with refine pankod refine react hook form This means you can now use Material UI for your forms and manage them using pankod refine react hook form First we ll create PostCreate page to create new records src pages posts createimport Box TextField Autocomplete useAutocomplete Create from pankod refine mui

will trigger the edit forms for each record allowing you to update the record data Deleting a recordDeleting a record can be done in two ways The first way is adding a delete button on each row since refine doesn t automatically add one so we have to update our lt PostList gt component to add a lt DeleteButton gt for each record We are going to add new cell to the Actions column to show delete button on each row src pages list tsximport React from react import useDataGrid DataGrid GridColumns EditButton DateField List Stack gt DeleteButton lt from pankod refine mui import IPost from

in an edit form Implementing mutation modeWe ll like to show how mutation modes making your app feel more responsive to the user Refine offers three modes for mutations called pessimistic optimistic and undoable This modes determines when the side effects are executed If we briefly describe pessimistic UI updates are delayed until the mutation is confirmed by the server optimistic UI updates are immediately updated before confirmed by server undoable UI updates are immediately updated but you can undo the mutation We ll implement undoable mutation mode The mutation is applied locally redirection and UI updates are executed immediately as if the mutation is successful Waits for a customizable amount of timeout period before mutation is applied During the timeout mutation can be cancelled from the notification with an undo button and UI will revert back accordingly Refer to Refine mutation mode docs for more detailed information→To activate mutation mode we ll set mutationMode property to the lt Refine gt component App tsx function App return lt ThemeProvider theme LightTheme gt lt CssBaseline gt lt GlobalStyles styles html WebkitFontSmoothing auto gt lt RefineSnackbarProvider gt lt Refine notificationProvider notificationProvider Layout Layout ReadyPage ReadyPage catchAll lt ErrorComponent gt routerProvider routerProvider authProvider authProvider

ThemeProvider gt export default App Tip The default timeout period is setted to ms You can change it by setting undoableTimeout property to the lt Refine gt component Sharing the current page with filtersImagine we need to share the current page with filtering and sorting parameters to our colleagues The proper way to do is sharing the URL that has include all needed parameters like posts current amp pageSize amp sort createdAt amp order descRefine offers syncWithLocation property that allow us to editing query parameters manually and share current page items count per page sort and filter parameters easily to others App tsx function App return lt ThemeProvider theme LightTheme gt lt CssBaseline gt lt GlobalStyles styles html WebkitFontSmoothing auto gt lt RefineSnackbarProvider gt lt Refine mutationMode undoable gt syncWithLocation lt gt lt RefineSnackbarProvider gt lt ThemeProvider gt export default App Now we can get current information from URL as a query parameters We can either use this link to share to others or define filter pagination and sorting parameters manually by changing URL parameters ConclusionIn this article we ll show you how to build a CRUD admin panel using refine and Material UI This approach will allow you to quickly create an admin interface for your application with minimal coding We ll start by setting up our project with the required dependencies Then we ll create our CRUD components using Material UI Finally we ll wire everything up and add some extra features from refine like mutation mode We covered How to bootstrap refine appConnecting Strapi v data provider to refine app Creating pages for CRUD operationsImplementing some of refine features like mutation mode and location sync refine is an open source tool that rapidly and flexibly develops for CRUD admin panels or web apps It is easy to get started with and doesn t require a lot of code It has nice documentation that covered examples guidelines and tutorials using best practices refine is constantly being updated with new features and improvements Refer to official refine page for more information→ Live StackBlitz ExampleUsername demo refine

海外TECH	DEV Community	How I host my Full-stack Application SaaS for Free on AWS	https://dev.to/ixartz/how-i-host-my-full-stack-application-saas-for-free-on-aws-41ij	How I host my Full stack Application SaaS for Free on AWSDeploying your application to production can become quite expensive on AWS if you don t take the time to think about your infrastructure In this article I will show you how I manage to host my full stack application for free on AWS Frontend Backend Database Monitoring and Email service all hosted for free on AWS ContextI m an indie maker with limited financial resources I need to optimize the hosting costs If you are working for a larger company this article can still give you some idea on how to reduce your cost on AWS My whole application is hosted on AWS Because everything is centralized on AWS it makes easier to manage the infrastructure Also as a solo developer with limited time the infrastructure is serverless So you don t need to worry about server management AWS handles it for you They configure and update the server for you Thanks to the centralization and serverless I can focus on my business and product You can check out the live demo of my application at the full stack React Boilerplate demo Or if you need to see a real SaaS product you can check out PostMage app AuthenticationLet s start by looking at the authentication where I use AWS Cognito to secure my full stack application All the authentication system is managed and secured by AWS so I don t need to worry about it With Cognito it s extremely easy to implement email and social authentication with Google Facebook Amazon and Apple The good news is that AWS Cognito has a very generous free tier policy Below monthly active users you can stay at the free tier without any time limitation always free I think it s one of the most generous free tier policies in the market For example Auth only offers monthly active users FrontendThe developer experience has recently improved with Netlify and Vercel With these two tools I can build and deploy your frontend directly from your GitHub repository Did you know you can have the same experience with AWS without any external services Yes with AWS Amplify Hosting you can host your frontend on AWS without compromising on your developer experience AWS Amplify Hosting also offers a free tier but it s limited to one year The free plan includes build minutes and GB of bandwidth per month Compared to Vercel and Netlify you don t need to pay a subscription for each developer seat With Amplify Hosting you only need to pay based on your usage BackendFor the REST API I host it on AWS Lambda the serverless computer service from AWS No need to set up an EC instance to host a backend So no need to update your server and no need to manage the scaling With AWS Lambda you only need to deploy your code and AWS will take care of the rest You can invoke your AWS Lambda million requests per month for free And it isn t limited in time When you go above the free tier you only need to pay based on the number of requests Basically you don t need to pay anything if you don t have any requests In the past you usually need an API gateway It s needed to route requests to the correct Lambda function It also comes at a small cost But again there is also a free tier Like AWS Lambda the API gateway can handle million requests per month for free More recently AWS has released AWS Lambda Function URLs So you can directly invoke your Lambda function without an API gateway And the good news with AWS Lambda Function URLs is free with Lambda DatabaseYou might already notice that there aren t a lot of providers for serverless databases Fortunately for us DynamoDB checks all the requirements you expected for a serverless database scale to zero pay per request automatically manage the scaling and so on So I choose DynamoDB as my database for my SaaS application Again I won t disappoint you DynamoDB has a very generous always free tier policy GB of storage provisioned Write and Read Capacity Based on the official description this enough to handle million requests per month I don t know this is true or not but I think it s definitely enough to handle a middle sized application for free Monitoring Logging and ObservabilityThe infrastructure is serverless and managed by AWS But I still need to keep an eye on the application to see if there are any errors So I use CloudWatch to monitor the application and the infrastructure I also set up some alerts to be notified when something goes wrong For CloudWatch AWS offers an always free tier custom metrics alarms GB of log ingestion etc Using only what the free tier offering you can still have a better idea of how your application is behaving in production EmailBy using AWS Cognito for the authentication there are several steps in the authentication process where Cognito will send an email with AWS SES For example if you have a registration form you can send a confirmation email to the user after he registers Not only for the authentication but the application itself also needs to send an email My SaaS application has team support where users can invite their friends or coworker to work together in the same workspace So the application needs to send an email when the user start inviting his friends You won t get any surprise But AWS SES has an extremely generous always free tier you can send emails per month for free I think it s one of the most generous free tiers in the market for email service ConclusionAll the AWS services I used for my SaaS application have a free tier Currently I m paying nothing for hosting my full stack application on AWS In this article I hope I give you some inspiration on how you can also reduce your AWS bill If you like my article and my stack you should be definitively interested in my Full stack React Boilerplate a pre configured template for you to start a new project quickly It s exactly the same stack mentioned in the article serverless hosted on AWS You ll find inside the boilerplate everything configures for you It includes TypeScript Tailwind CSS Serverless framework Linter Code formatter Jest Cypress and VSCode configuration So you don t need to lose your time fighting with configuration files Not only you ll find configuration files in the boilerplate but you ll also find code for your application For example it includes pre built code for authentication landing page user dashboard multi tenancy support team support subscription payment and more Instead of wasting time reinventing the wheel and developing from scratch you can focus on the core of your project It ll save you months of development time	2022-07-27 14:04:45

海外TECH	Engadget	The best smart speakers you can buy	https://www.engadget.com/2020-01-22-smart-speakers-guide-google-amazon-echo-sonos.html?src=rss	The best smart speakers you can buyWhen Amazon first introduced Alexa and the Echo speaker years ago the idea of talking to a digital assistant wasn t totally novel Both the iPhone and Android phones had semi intelligent voice controls ーbut with the Echo Amazon took its first step toward making something like Alexa a constant presence in your home Since then Apple and Google have followed suit and now there s a huge variety of smart speakers available at various price points As the market exploded the downsides of having a device that s always listening for a wake word have become increasingly apparent They can get activated unintentionally sending private recordings back to monolithic companies to analyze And even at the best of times giving more personal information to Amazon Apple and Google can be a questionable decision That said all these companies have made it easier to manage how your data is used ーyou can opt out of humans reviewing some of your voice queries and it s also less complicated to manage and erase your history with various digital assistants too The good news is that there s never been a better time to get a smart speaker particularly if you re a music fan For all their benefits the original Amazon Echo and Google Home devices did not sound good Sonos on the other hand made great sounding WiFi connected speakers but they lacked any voice controlled smarts That s all changed now Sonos is including both Alexa and Google Assistant support in its latest speakers Google and Amazon meanwhile made massive improvements in sound quality with recent speakers Even lower end models like the Echo Dot and Nest Mini sound much better than earlier iterations With the growing popularity of these speakers there are now more options than ever Let s walk through the best choices at different price points and for different uses Picking an assistantThe first thing most people should do is decide what voice assistant they want to use Google Assistant and Amazon s Alexa are both well supported options that are continually evolving with new features added at a steady clip A few years ago Alexa worked with more smart home devices but at this point basically any smart device worth buying works with both It s mostly a matter of personal preference If you already use Google Assistant on your Android phone it makes sense to stick with that But while Alexa isn t quite as good at answering general knowledge questions it syncs just fine with things like calendars from your Google account And it works with perhaps the widest variety of smart home devices as well If you ve never used Alexa or Google Assistant you can download their apps to your smart phone and spend some time testing them out before buying a speaker As for Apple you won t be surprised to learn its HomePod mini is the only Siri compatible speaker on the market now that Apple has discontinued the larger HomePod Siri has a reputation for not being as smart as Alexa or Google Assistant but it s totally capable of handling common voice queries like answering questions controlling smart home devices sending messages making calls and playing music Technically Siri and Apple s HomeKit technology doesn t work with as many smart home devices as the competition but it s not hard to find compatible gear And since the HomePod mini arrived last fall Apple has added some handy features like a new Intercom tool Apple is also starting to support music services besides Apple Music Currently Pandora is the only other option but Apple has confirmed that Amazon Music will eventually work natively on the HomePod mini as well Best smart speaker under Amazon Echo DotEngadgetMost people s entry point into the smart speaker world will not be an expensive device Amazon s fourth generation Echo Dot and Google s Nest Mini are the most obvious places to start for two important reasons One they re cheap Both the Nest Mini and Echo Dost cost Two they re capable Despite the low price these speakers can do virtually the same things as larger and more expensive devices Buy Echo Dot at Amazon Buy Nest Mini at Walmart The Nest Mini was released in late but Amazon just refreshed the Echo Dot in After testing both devices I think the Echo Dot is the best small smart speaker for most people Amazon keeps improving the audio quality across its Echo line and the Echo Dot is no exception It produces much louder and clearer audio than I d expect from a speaker The Nest Mini doesn t sound bad and it s perfectly fine for listening in the bedroom while getting ready for the day but the Echo Dot is a better all purpose music listening device From a design perspective Amazon broke the mold with the latest Echo Dot Instead of a small puck like the Nest Mini the new Dot is shaped like a little globe It s much bigger than the Nest Mini but that size gives it room for higher end audio components The Dot keeps the handy physical volume buttons and mute switch on top along with a button to activate Alexa While the Dot doesn t look as sleek as the Nest Mini having physical buttons makes it easier to adjust volume and mute the mic I do wish the Dot had a way to physically pause music on the Nest Mini if you tap the middle of the device the music stops Another benefit the Echo Dot has over the Nest Mini is its mm audio out jack which means you can plug it into other speakers and instantly upgrade the audio quality When you do that you can ask Alexa to stream music and it ll output to whatever speaker you have connected That ll help you get more mileage out of the Dot in the long run The Nest Mini answers with a handy wall mount for people who want to keep their counter or shelf clear The Echo Dot s new bulbous form is definitely not suited to this so if you want a speaker you can really hide the Nest Mini is probably the better choice Overall the Dot is the best choice for most people but I wouldn t hesitate to recommend the Nest Mini either I generally prefer using Google Assistant over Alexa and anyone who feels the same should go ahead and get the Nest Mini The Dot does sound notably better so if you plan to listen to audio on a regular basis that s probably the way to go But if you only plan to use it for a quick song or podcast when you re getting ready in the morning just pick your favorite assistant and go from there Best smart speaker under Amazon EchoAmazonAmazon Apple and Google all have smart speakers the fourth generation Echo the HomePod mini and the Nest Audio respectively All three companies claim superior audio quality so for lots of people these speakers will be the sweet spot between small speakers like the Echo Dot and Nest Mini and bigger more expensive models like the Sonos One Buy Echo at Amazon Buy HomePod mini at B amp H Buy Nest Audio at Walmart Once again Amazon punches above its weight Like the Dot the new Echo is totally redesigned and the new internals were made with music in mind It combines a three inch woofer with two inch tweeters ーa more advanced setup than either the Nest Audio or HomePod mini The Nest Audio uses a three inch woofer but only a single inch tweeter while the HomePod mini makes do with a single “full range driver and two passive radiators In practice this means the Echo is noticeably louder than either the Nest Audio or HomePod mini and much better suited to filling a large room than the competition It also delivers an impressive bass thump and powerful mid range frequencies In fact my main complaint with the speaker is that highs aren t quite crisp enough Compare the Echo to a Sonos One and the One sounds much more lively while the Echo comes off a bit muddy Then again the Sonos One costs twice as much as the Echo While the Echo may beat the Nest Audio and HomePod mini on volume and bass Google and Apple s speakers are not bad options The HomePod mini is the quietest of the three speakers but it still sounds balanced across the entire audio spectrum The bass isn t too assertive but there s more presence than I would have expected given its tiny size it s by far the smallest of these three speakers And it has a few nice perks if you re using an iPhone or newer Thanks to the U “ultra wideband chip in recent iPhones the HomePod mini can tell when there s a phone near it which makes handing off music from your phone to the speaker or vice versa quite simple Playback controls for the HomePod mini will automatically pop up as well and your phone s lock screen will display music suggestions if the speaker isn t currently playing Setup is also dead simple ーjust bring an iPhone or iPad near the speaker and it ll automatically start the process Google s Nest Audio is also quite pleasant to listen to It s a little louder than the HomePod mini and has stronger bass to boot It doesn t have the same overall power and presence that the Echo does but for it s a well balanced speaker that should serve most people s needs All three of these speakers support stereo pairing as well if you want more volume or crave a more immersive experience For two Echoes will fill a large room with high quality sound and enough bass to power a party A pair of HomePod mini or Nest Audio speakers aren t quite as powerful but it makes for a great upgrade if you re a more avid listener A pair of Nest Audio or HomePod mini speakers sounded great on my desk during the workday I don t need overwhelming volume but can appreciate the stereo separation And two of those speakers together can easily power a larger living space although the Echo is the better choice if volume is a priority Here too I think that picking the assistant that works best in your house and with your other gadgets is probably the most important factor ーbut given Alexa s ubiquity and the new Echo s superior sound quality I think it s the best smart speaker at this price point Best midrange smart speakers Sonos One Amazon Echo StudioIf you have more than a passing interest in music the Echo Dot and Nest Mini aren t really going to cut it Spending more money to upgrade to a speaker designed with audio in mind is one of the best decisions I ve made For years I didn t have a proper home music solution but in the end the modest investment has made my life much more pleasant For a long time my default recommendation was the Sonos One It hits a sweet spot of size and convenience and it s a huge upgrade in sound quality over the Nest Mini or Echo Dot not to mention the larger Echo and Nest Audio You can use either Alexa or the Google Assistant with it and Sonos supports a huge variety of music services But most importantly it simply sounds great especially if you tune the speaker to your room using the Sonos iOS app It takes just a few minutes and makes the One sound lively with punchy bass and clear highs Buy Sonos One at Sonos Buy Echo Studio at Amazon But Amazon flipped the script in with the Echo Studio a Alexa powered smart speaker that can stand up against the Sonos One Yes it s larger than nearly every other speaker in this guide but the bang for the buck factor is extremely high with the Echo Studio Naturally it s a full fledged member of the Alexa ecosystem which means you can do multi room playback with other Echo speakers or set up two Studios in a stereo pair All of Alexa s features are on board here and it has a built in Zigbee smart home hub if you happen to need that The Echo Studio has a few other unique features for music lovers If you sign up for Amazon s hi def music service you can play a very limited selection of songs in Sony s Reality Audio format Amazon refers to this as D music It may sound great but the selection is so sparse that we can t recommend it as a reason to buy into the Echo Studio ーbut it will be nice as Amazon expands its catalog over time That said the Echo Studio s five speaker degree design naturally provides a more D effect than a speaker like the Sonos One which has a more traditional forward firing design The Studio also supports Dolby Atmos making it a candidate for a home theater setup ーbut it only works with Amazon s own Fire TV devices And using a single speaker for watching movies is odd it may sound great but it s not the immersive experience you ll get with a dedicated soundbar and surround speakers A stereo pair plus Amazon s Echo Sub should sound notably better but we haven t been able to get that setup yet Given the quality of the Studio the speaker shines when used with a high def streaming service like Amazon Music HD or Tidal s HiFi tier The downside is that you ll pay for those ーbut if you want to stick with standard Spotify or Apple Music the Studio still sounds great While the Studio is comparable to the Sonos One in terms of pure audio quality the Sonos ecosystem does have a few advantages over Amazon Sonos speakers that support voice commands like the One work with either Alexa or Google Assistant So if you prefer Google Sonos is probably the way to go And Sonos speakers work with a much broader set of music services I ve spent a lot of time recently comparing the One to the Echo Studio and I go back and forth on which is superior in terms of music quality They definitely have different profiles and while I have come to prefer Sonos over Amazon I know plenty of people including my colleague Billy Steele who find the opposite to be true If you have a smaller home and aren t concerned with multi room playback the Echo Studio should be your pick But if you re interested in building out a multi room setup over time Sonos currently provides a greater variety of speakers for that mission But either way you ll end up with a setup that puts something like the Echo Dot or Nest Mini to shame Best smart speaker for music lovers Sonos FiveAs nice as the Echo Studio and Sonos One are there s only so much you can get out of them If you crave more bass clarity and stereo separation the Sonos Five is one of our favorite pure music speakers It has all the conveniences of the One except for one which we ll get to and sounds significantly better than any other Sonos speaker It also sounds much better than the Echo Studio and anything Google is currently selling Buy Sonos Five at Sonos That said the Five stretches our definition of a smart speaker here because it doesn t have a built in voice assistant But it s so good at music playback that it s worth recommending you pick one up along with an Echo Dot or Nest Mini Both of those speakers work with Sonos so you can use voice commands to control the Five just as you would a dedicated Alexa or Google Assistant device It s also easier to recommend than it was a year ago because Sonos refreshed the speaker last spring with a new wireless radio as well as more memory and a faster processor This means it should stay current and work with future Sonos software updates for years to come Since we re talking best here I m going to go ahead and recommend that true music junkies splash out on two Five speakers and pair them in stereo Put simply it s the most enjoyable experience I ve had listening to music in years I found myself picking up new details while listening to albums I ve heard over and over again It s a wonderful experience and worth saving for if you re a music lover Put simply I didn t know what I was missing until I tried the Five Best portable smart speaker Sonos RoamEngadgetWhile many people will be happy with a few speakers strategically placed throughout their home you might want something that works outside as well as inside Fortunately you can find speakers that pair voice controls and strong music playback performance with portable weatherproof form factors For my money it s hard to beat the Sonos Roam for sheer versatility not to mention audio quality Buy Sonos Roam at Sonos When used inside the home the Roam works like any other Sonos speaker It fits in with an existing multi room Sonos setup or you can get a pair for stereo playback Like most other Sonos speakers it works with either the Google Assistant or Amazon Alexa and it supports essentially every major music service available It sounds very good given its tiny size it s quieter and not quite as clear as the Sonos One but it still packs a surprising bass thump and distinct highs Since it was designed with on the go usage in mind the Roam has a battery and Bluetooth so you can take it anywhere and use it far away from your WiFi network And its diminutive size makes it easy to take it everywhere both around the house and out and about It s also the first Sonos speaker that is fully waterproof as well as dust and drop resistant so you shouldn t worry about taking it to the pool or beach The Roam gets about hours of battery life whether you re on WiFI or Bluetooth There are other portable speakers that last longer so if you re really going to push the battery you might be better served by another option Sonos also has another portable option the Move Like the Roam it s a full fledged Sonos speaker when on WiFi and works with Bluetooth when you re away from home But it s and much larger than the Roam and even bigger than the Sonos One This means it is very loud and has better audio quality than all the other speakers I ve mentioned but it s not something you can toss in a bag and bring with you anywhere When I reviewed it I liked having a speaker I could tote around the house with me and out to my porch but the Roam does that all just as well in a much smaller package The Move is a good option if you want a high quality speaker for a living room with the option to occasionally drag it to the backyard While this guide is all about smart speakers we d be remiss if we didn t mention all of the solid portable speakers out there that either have limited smart features or none at all We have an entire guide to the best portable Bluetooth speakers and some of our favorites that support smart voice commands come from Bose The SoundLink Flex supports Siri and Google Assistant commands plus it has an IP design that s roughly the size of a small clutch bag It pumps out bright dynamic sound and can pair with other speakers for stereo sound too On the higher end of the spectrum the Bose Portable Smart speaker supports Alexa and Google Assistant commands and since it can connect to WiFi you can ask your preferred assistant to play music from Spotify Amazon Music and other services On top of that it produces well rounded sound sports an IPX design with a convenient carry handle and will last up to hours on a single charge	2022-07-27 14:15:15
