海外TECH DEV Community Refine vs React-Admin Which is Better for Your Project? https://dev.to/pankod/refine-vs-react-admin-which-is-better-for-your-project-nj0 Refine vs React Admin Which is Better for Your Project If you are reading this chances are you are a developer researching options for delivering an admin panel or another internal tool Together with you we will take a look at the best admin panel frameworks in response to this need Motivation is our most important resource when developing a project If you lose your motivation as your project progresses you will not be able to produce a successful product The point where you will lose this feeling the most is the point where you cannot meet your Business needs Different UI UX solutions may be requested for many business models and it is very important that you can realize them regardless of the framework you use When you decide to use these types of frameworks we need to know to what extent and how they solve your work If we do not know what these frameworks do and how customizable they are the problems we may encounter can reduce our motivation We will examine how the frameworks we will talk about solve our work and how customizable they are under the title of Customization React AdminReact Admin is an BB application framework based on Material Design using Material UI It provides ready to fetch data components so you just compose them together to create an application It can fetch data from any API connected to the data source like REST GraphQL RPC It s powered by React React Router Redux and Redux Saga while Material UI is responsible for the visual React admin uses Redux and redux saga for state management React Admin creates actions and reducers automatically Developer should only create data provider which is used for running requests to the server side and parse server responses But in some cases it is necessary to run non typical request to the server side or to change custom Store parameters In this case React Admin gives possibility to create custom actions reducers and sagas React admin is a framework that has been developed for a long time and has a wider community Besides being stable it works with old technologies InstallationCan be included in another React app Installation is very simplenpm install react admin oryarn add react admin FeaturesIt can be used with any backend Rest GraphQL SOAP API based The UI fetches the data from an API connected to the data source Powered by Material UI Redux Redux Saga React router Supports any authentication provider of your choice REST API OAuth Basic Auth Internationalization Uses inSupports data validation SSR Next js SupportReact Admin does not support SSR Next js Therefore it only helps you develop BB and admin panel applications RoutingReact admin does it with react router dom to save routes You need to create your own module and define it in the lt Route gt component import as React from react import Route from react router dom import Foo from Foo import Bar from Bar export default lt Route exact path foo component Foo gt lt Route exact path bar component Bar gt Then pass this array as customRoutes prop in the lt Admin gt component import as React from react import Admin from react admin import customRoutes from customRoutes const App gt lt Admin customRoutes customRoutes dataProvider simpleRestProvider gt lt Admin gt export default App Now when a user browses to foo or bar the components you defined will appear in the main part of the screen Data Provider LogicWhen React admin needs to communicate with API it uses Data Provider Here are the React Admin data provider methods const dataProvider getList resource params gt Promise getOne resource params gt Promise getMany resource params gt Promise getManyReference resource params gt Promise create resource params gt Promise update resource params gt Promise updateMany resource params gt Promise delete resource params gt Promise deleteMany resource params gt Promise GraphQL Data ProviderWe can say that React Admin is a bit lacking in terms of both graphql provider and its documentation React Admin calls the GraphQL endpoint by running an introspection query for GraphQL import React from react import Component from react import buildGraphQLProvider from ra data graphql simple import Admin Resource from react admin import PostCreate PostEdit PostList from posts const App gt const dataProvider setDataProvider React useState null React useEffect gt buildGraphQLProvider clientOptions uri http localhost then graphQlDataProvider gt setDataProvider gt graphQlDataProvider if dataProvider return lt div gt Loading lt div gt return lt Admin dataProvider dataProvider gt lt Resource name Post list PostList edit PostEdit create PostCreate gt lt Admin gt export default App When we want to see this data in a table all GraphQL entities are queried requested by default even if you don t add columns to the table This is against GraphQL s approach and is a scenario we would not want The way to prevent this is to override all your queries import buildGraphQLProvider buildQuery from ra data graphql simple const myBuildQuery introspection gt fetchType resource params gt const builtQuery buildQuery introspection fetchType resource params if resource Command amp amp fetchType GET ONE return Use the default query variables and parseResponse builtQuery Override the query query gql query Command id ID data Command id id id reference customer id firstName lastName return builtQuery export default buildGraphQLProvider buildQuery myBuildQuery Although this is a solution it complicates your project in many ways debugging maintenence etc React Admin Avaible ProvidersThe providers that React admin supports are as follows Simple Rest Json Server Simple GrapgQL Local JSON Local Strage Supabase You can view the full list of providers here gt CustomizationWith React Admin you can develop effective BB applications and admin panels in a very short time Although most of the processes are handled with hooks the general architecture is built on components In general we can say that it is customizable but not very flexible In some cases or business models you may need to think about this yourself and make some additions UI UX Customization React Admin offers solutions in component architecture The disadvantage of this is that you will have difficulty meeting your customization needs or different business requests These customizable but they can be a bit of a hard for different business models Logic Customization React Admin uses redux and redux saga for state management You should know these two technologies well In some cases you may need to create the actions and reducers yourself This is also a disadvantage for many situations PricingIn addition to these features it provides React Admin offers some modules as Enterprise Edition A few of these modules are as follows RBACEditable DatagridRealtimeSearch NavigationFor more information about Enterprise Edition and other modulesReact Admin Docs amp Demo Documentation Live Demo Refinerefine is a React based framework that helps you to develop admin panel BB and dashboard that can be fully customized with Ant Design refine directly provides Ant Design components and some hooks to work with those components These hooks give you the required props for those Ant Design components refine is a collection of helper hooks components and providers They are all decoupled from your UI components and business logic so they never keep you from customizing your UI or coding your own flow refine uses React Query for data processing caching and state management In this respect you do not need to define anything extra for every cases and model Although refine is a newer framework it is successful in identifying deficiencies in development and producing solutions accordingly Using new technologies it offers users more effective and simpler development options InstallationInstallation is very simple and customizable options can be added npx superplate cli demo refine project FeaturesConfiguration One line setup with superplate

React Location React Location router provider support SSR Next js Supportrefine has support for SSR Next js This is an important feature that separates refine from other frameworks Thanks to this feature refine provides the opportunity to develop BC applications in addition to BB and admin panel refine can be used with Next js to SSR your pages It doesn t get in the way and follows Next js conventions and also provides helper modules when necessary SSR Next js Setupnpm i pankod refine pankod refine nextjs router SSR Next js Basic Usage lt Refine gt must wrap your pages in a custom App

React Query to manage data fetching React Query handles important concerns like caching invalidation loading states etc GraphQL Data ProviderIt is well covered by GraphQL data provider refine and explained step by step in the documentation refine GraphQL data provider is built with qql query builder and graphql request The purpose here is to send dynamic queries that we can do with qql query builder as requests with graphql request Query builder helps us build queries and mutations We can use these queries with the getList getMany and getOne methods in our data provider On the other hand the create createMany update updateMany deleteOne and deleteMany methods generate a mutation to send a request In order to create a query we need to specify the fields that we will use from our data

Support and Training For more info about Enterprise gt refine Docs amp Demo Documentation Live Demo ConclusionWith the pricing customization and flexibility that refine offers you you will be able to meet all your business demands In addition you can easily develop both BB and BC applications using a single framework with the support of SSR Next js In general these frameworks that we are comparing have appeared for the same purpose All of them are successful in meeting business demands and offering you a solution Here are the this solutions way that they offer they may differ and there may be distinguishing features between them At this point the questions you should ask when choosing these of framework may be as follows How flexible are they in offering solutions to the different business demands we may encounter How difficult will it be to implement the providers and features we will be using If any problem arises can I easily find a solution from the documentation How dependent am I on this framework when using it in my project and does it offer customization possibilities What does it offer me as an extra feature In this article we tried to answer these questions By reading this article you can choose the appropriate framework for your project and use it This comparison table strives to be as accurate and as unbiased as possible If you use any of these libraries and feel the information could be improved feel free to suggest changes with notes or evidence of claims contact info refine dev or you can open a issue on Github 2021-11-29 06:39:22
海外TECH DEV Community JavaScript Reduce Method Made Simple https://dev.to/alexdevero/javascript-reduce-method-made-simple-1hb3 JavaScript Reduce Method Made SimpleThe JavaScript reduce method is one of the most used array methods It is also a part of functional programming In this tutorial you will learn what the reduce method is and how it works You will also learn how to use this method and what are some of the things it can do with it IntroductionThe reduce method is one of the features that was add to JavaScript in ES ECMAScript It quickly became one of the most often used array methods What this method does is it reduces a given array into a single value by executing a reducer function you provided It essentially reduces an array into a single value The syntaxThe syntax of reduce method is simple This method takes two parameters The first one is a callback function The callback function will be invoked for every element in the array When it is invoked the reduce passes four parameters into this callback function These parameters are accumulator currentValue index and the original array The accumulator is the value reduce returns after the last call of the callback One exception is when reduce runs for the first time In this case the value of accumulator is the value you provided as the initialValue argument The currentValue is the current element being processed in a given array The index is the index of the current element that is being processed in the array If you provide the initialValue this index starts at If you omit the initialValue index will start at Last parameter is the array that is being processed The second parameter of reduce method is the initialValue This is the initial value you want the reduce method to start with This initial value is used as the first argument for the first call of the callback function If you omit it reduce will use the first element in the array as the initial value Syntax of reduce someArray reduce callback initialValue Hypothetical reducer callback function const reducer accumulator currentValue index gt do something UsageThe reduce method is usually used for operations such as calculating total sums and averages or finding minimum and maximum values in a given array That said you can also use reduce for other things For example to change structure of objects or to flatten two dimensional arrays Summing values in an arrayOne of the simplest examples of using the reduce method is summing values in an array This can be done with a simple callback function in which we take the currentValue and add it to the accumulator This will repeat for every iteration currentValue will be added to the increasing value of the accumulator After the last number in the array is processed reduce will return the accumulated value of accumulator If we want the reduce to start from a different number than we can set that starting number as the initial value Otherwise we can set the initial value to and reduce will start with that Create array of numbers const numbers Sum the numbers array const sum numbers reduce accumulator currentValue index gt accumulator currentValue For each iteration add the currentValue to the value of the accumulator Log the result console log sum Finding averagesWe can also use if else statement to return different results from the callback function This is handy for example when we want to get the average of numbers in an array We can add a if else statement that will check if the currently processed item is the last item of the array This check will use the index of currently processed item and the length of the array If the currently processed item is the last item in the array we will divide the accumulated value by the length of the array If it is not the last item we will return the accumulated value Before each check we will add the currently processed value to the accumulator Create array of numbers const numbers Find the average const average array reduce accumulator currentValue index array gt For each iteration add the currentValue to the value of the accumulator accumulator currentValue Check if currentItem is the last item in the array if index array length If it is divide the accumulated value by the length of the array and return the result return accumulator array length else Otherwise return the accumulated value return accumulator Log the result console log average Finding minimum and maximum valuesWe can use reduce to find the minimum value in an array by comparing the value of accumulator and currentValue arguments If the value of accumulator is less than the value of currentValue we will return the accumulator Otherwise we will return the currentValue Create array of numbers const numbers Find minimum value const min numbers reduce accumulator currentValue gt If the value of accumulator is less than currentValue return the accumulator else return the currentValue return accumulator lt currentValue accumulator currentValue Log the result console log min We can easily find the maximum value by switching the condition inside the callback function Create array of numbers const numbers Find maximum value const max numbers reduce accumulator currentValue gt If the value of accumulator is greater than currentValue return the accumulator else return the currentValue return accumulator gt currentValue accumulator currentValue Log the result console log max Flattening arraysThe reduce method can be also helpful when we want to flatten multi dimensional arrays We can do this by using the concat method on the accumulator passing the currentValue as an argument to the concat method Note that this simple solution will work only with two dimensional arrays If you have an array with more than two dimensions the flat method will do the job Create array of numbers const numbers Flatten an array const numbersFlattened numbers reduce accumulator currentValue gt Concatenate the accumulator with the currentValue return accumulator concat currentValue Log the result console log numbersFlattened Counting number of occurrencesWe can use the reduce method also for tasks such as counting the number an item occurred in an array We can do this by setting the initial value to an empty object During each iteration we will check if currently processed item is an existing property of that object If it is we will change the value of this property by This is the number of occurrences If the item is not an existing property we will add it with a value of Then we will return the accumulator object At the end we will get an object with all items as properties and number of occurrences as values Create array of numbers const fruit apple pear lemon avocado apple banana pear apple pineapple Count the number of occurrences const occurrences fruit reduce accumulator currentItem gt Check if item exists in accumulator object if currentItem in accumulator If so increase the number of occurrences by accumulator currentItem accumulator currentItem else Else register new occurrence accumulator currentItem Return the accumulator object return accumulator Log the result console log occurrences apple pear lemon avocado banana pineapple Changing shape of objects inside arraysWhen we reduce an array we don t have to reduce it to a single value We can also change its content For example if it is an array of objects we can change the shape of those objects The returned value will be still an array only the shape of the objects inside the array will be different Create array of numbers const records name Joe grade A name Tom grade B name Sandra grade B name Joel grade C name Victoria grade A Change the structure of objects in records array const updatedRecords records reduce accumulator currentItem gt During each iteration transform currently processed object into this shape accumulator currentItem name grade currentItem grade passed A B includes currentItem grade Return the modified object return accumulator Log the result console log updatedRecords Joe grade A passed true Tom grade B passed true Sandra grade B passed true Joel grade C passed false Victoria grade A passed true Conclusion JavaScript Reduce Method Made SimpleEven thought the syntax of reduce method is simple it can help us do interesting things with arrays I hope that this tutorial helped you understand what the reduce method does how it works and how to use it 2021-11-29 06:33:22
