海外TECH	DEV Community	Best practices every beginner in React.js must follow to increase productivity	https://dev.to/qbentil/best-practices-every-beginner-in-reactjs-must-follow-to-increase-productivity-2kjc	Best practices every beginner in React js must follow to increase productivityReact js is a powerful and versatile library that has become one of the most popular choices for building user interfaces With its modular architecture performance optimizations and extensive community support React has revolutionized the way we create web applications However for beginners React can be quite overwhelming and it s easy to get lost in the sea of concepts tools and best practices As a beginner in React js it s important to understand the fundamental principles and best practices that can help you become more productive and efficient in your development process Whether you re building a simple todo app or a complex e commerce platform following these best practices can help you write clean maintainable and scalable code and avoid common pitfalls and mistakes Keep your components small and reusableA good rule of thumb is to follow the Single Responsibility Principle SRP and ensure your components are responsible for only one thing For example you could create a separate component for each input field such as username password and email address By keeping components small and reusable you can easily test them debug them and maintain them in the long run Example snippetimport React from react function InputField type name placeholder return lt div gt lt label htmlFor name gt name lt label gt lt input type type id name name name placeholder placeholder gt lt div gt export default InputField Use JSX correctlyJSX is a syntax extension for JavaScript that allows you to write HTML like code in your JavaScript files When using JSX make sure you use curly braces to embed JavaScript expressions within JSX code and use camelCase naming conventions for HTML attributes For example instead of using class as an attribute use className instead Avoid using if else statements in your JSX code and use conditional rendering instead to make it easier to read and maintain your code Example snippetimport React from react function Button text onClick return lt button onClick onClick gt text lt button gt function App const handleClick gt console log Button clicked return lt div gt lt h gt Hello World lt h gt lt Button text Click me onClick handleClick gt lt div gt export default App Follow the one way data flowThe one way data flow is a fundamental concept in React where data flows in one direction from the parent component to its children Avoid modifying the state of a child component from its parent and use props to pass data down from the parent to its children For example if you have a shopping cart component the parent component can pass the items to the cart component as a prop Example snippetimport React useState from react function ParentComponent const items setItems useState item item const handleAddItem gt const newItem item items length setItems items newItem return lt div gt lt button onClick handleAddItem gt Add item lt button gt lt ChildComponent items items gt lt div gt function ChildComponent items return lt ul gt items map item gt lt li key item gt item lt li gt lt ul gt export default ParentComponent Use React DevToolsReact DevTools is a browser extension that allows you to inspect and debug React components You can see the hierarchy of your components inspect their props and state and even modify them in real time For example if you have a bug in your code React DevTools can help you identify the source of the problem and make it easier to fix it import React useState from react function Counter const count setCount useState const handleIncrement gt setCount count const handleDecrement gt setCount count return lt div gt lt h gt Count count lt h gt lt button onClick handleIncrement gt Increment lt button gt lt button onClick handleDecrement gt Decrement lt button gt lt div gt export default Counter Use a CSS in JS libraryStyling components in React can be a challenging task especially for beginners Using a CSS in JS library like styled components or emotion can help you write cleaner and more maintainable code For example you can use a CSS in JS library to style a button component directly in your JavaScript file without having to create a separate CSS file Example code snippetimport styled from styled components const Button styled button background color caf border none color white padding px px text align center text decoration none display inline block font size px border radius px function App return lt div gt lt h gt Hello World lt h gt lt Button gt Click me lt Button gt lt div gt export default App Use React hooksReact hooks are a set of functions that allow you to use state and other React features in functional components Hooks can simplify your code reduce the number of class components you need to write and make it easier to share logic across different components For example you can use the useState hook to manage the state of your components and make it easier to update them based on user interactions import React useState from react function Counter const count setCount useState const handleIncrement gt setCount count const handleDecrement gt setCount count return lt div gt lt h gt Count count lt h gt lt button onClick handleIncrement gt Increment lt button gt lt button onClick handleDecrement gt Decrement lt button gt lt div gt export default Counter Use PropTypes or TypeScriptReact allows you to define the type of props that a component should receive using PropTypes or TypeScript Using these tools can help you catch errors early and ensure that your code is robust and maintainable For example if you have a component that requires a specific prop type using PropTypes or TypeScript can help you avoid type related bugs and provide better documentation for your components Example snippet on PropTypesimport React from react import PropTypes from prop types function Person name age email return lt div gt lt h gt name lt h gt lt p gt Age age lt p gt lt p gt Email email lt p gt lt div gt Person propTypes name PropTypes string isRequired age PropTypes number isRequired email PropTypes string isRequired export default Person Example snippet on TypeScriptimport React useState from react interface CounterProps initialValue number function Counter initialValue CounterProps const count setCount useState initialValue const handleIncrement gt setCount count const handleDecrement gt setCount count return lt div gt lt h gt Count count lt h gt lt button onClick handleIncrement gt Increment lt button gt lt button onClick handleDecrement gt Decrement lt button gt lt div gt export default Counter By the end of this article you ll have a better understanding of how to structure your components use JSX correctly manage state and props debug and inspect your code and leverage the latest tools and techniques to create high quality applications Whether you re a beginner or an experienced developer these best practices can help you become a better React developer and take your skills to the next level So let s dive in and explore the world of React best practices ConclusionIn this article we have explored some of the best practices that every beginner should follow to increase productivity and build efficient React applications From keeping your components small and reusable to using React DevTools CSS in JS libraries and TypeScript we have cover a range of topics that can help you improve your coding skills and build better applications Following these best practices can help you become a more efficient and effective React developer By keeping your components small and reusable using JSX correctly following the one way data flow using React DevTools using a CSS in JS library using React hooks and using PropTypes or TypeScript you can write clean maintainable and scalable

海外TECH	DEV Community	ASP.NET Core in .NET 8 is On The Way! 5 New Features Reviewed	https://dev.to/bytehide/aspnet-core-in-net-8-is-on-the-way-5-new-features-reviewed-4014	ASP NET Core in  NET is On The Way New Features ReviewedIn this article we delve into the exciting new features and updates introduced in ASP NET Core NET Preview We will explore the addition of ASP NET Core support for native AOT server side rendering with Blazor rendering Razor components outside of ASP NET Core sections support in Blazor monitoring Blazor Server circuit activity SIMD enabled by default for Blazor WebAssembly apps request timeouts and short circuit routes Join us as we take a closer look at these enhancements and how they can improve your web development experience Native AOT in ASP NET CoreHold onto your hats NET Preview brings native AOT support for ASP NET Core perfect for cloud native API apps Now publishing an ASP NET Core app with native AOT creates a self contained app AOT compiled to native code No more need for the NET runtime on the machine Why native AOT rocks in ASP NET CoreASP NET Core apps with native AOT have a smaller footprint lightning fast startup and use less memory How cool is that Plus the benefits shine in workloads with many instances like cloud infrastructure and massive services Native AOT offers Smaller disk footprint One executable contains the program and used code from external dependencies leading to smaller container images and quicker deployment Faster startup time No more JIT compilation means the app is ready in a jiffy making deployments with container orchestrators a breeze Lower memory use With less memory needed you ll see better deployment density and scalability In Microsoft s tests a simple ASP NET Core API app with native AOT saw faster startup time and smaller app size That s a game changer Minimal APIs Meet Native AOTGet ready for a fantastic combo Minimal APIs are now compatible with native AOT thanks to the Request Delegate Generator RDG As a source generator RDG turns those MapGet MapPost and other calls into RequestDelegates with routes during compile time No more runtime code generation RDG comes to life when you enable native AOT publishing Want to test your project s readiness for native AOT or reduce startup time Manually enable RDG with lt EnableRequestDelegateGenerator gt true lt EnableRequestDelegateGenerator gt in your project file Minimal APIs love JSON payloads so the System Text Json source generator steps in to handle them Just register a JsonSerializerContext with ASP NET Core s dependency injection Check Microsoft example Register the JSON serializer context with DIbuilder Services ConfigureHttpJsonOptions options gt options SerializerOptions AddContext lt AppJsonSerializerContext gt Add types used in your Minimal APIs to source generated JSON serializer content JsonSerializable typeof Todo internal partial class AppJsonSerializerContext JsonSerializerContext Now you ve got a powerful mix of Minimal APIs and native AOT Get Started with Native AOT ready TemplatesSource MicrosoftIn this preview Microsoft unveils two native AOT enabled project templates for ASP NET Core The “ASP NET Core gRPC Service template now has an “Enable native AOT publish option Tick that box and lt PublishAot gt true lt PublishAot gt pops up in your csproj file Introducing the fresh “ASP NET Core API template designed for cloud native API first projects It s different from the “Web API template because it Only uses Minimal APIs no MVC yet Employs WebApplication CreateSlimBuilder for essential features Listens to HTTP only cloud native deployments handle HTTPS Skips IIS or IIS Express launch profiles Enables JSON serializer source generator for native AOT Swaps weather forecast sample for a “Todos API Temporarily uses Workstation GC to minimize memory useCreate a new API project with native AOT using the dotnet CLI dotnet new api aotThe new “ASP NET Core API template generates this Program cs content as you can see in the Microsoft example using System Text Json Serialization using MyApiApplication var builder WebApplication CreateSlimBuilder args builder Logging AddConsole builder Services ConfigureHttpJsonOptions options gt options SerializerOptions AddContext lt AppJsonSerializerContext gt var app builder Build var sampleTodos TodoGenerator GenerateTodos ToArray var todosApi app MapGroup todos todosApi MapGet gt sampleTodos todosApi MapGet id int id gt sampleTodos FirstOrDefault a gt a Id id is todo Results Ok todo Results NotFound app Run JsonSerializable typeof Todo internal partial class AppJsonSerializerContext JsonSerializerContext Ready set go with native AOT templates Manage Request TimeoutsIn this preview release Microsoft presents a new middleware for handling request timeouts Now you can easily set timeouts for specific endpoints controllers or on the fly per request First add the request timeout services builder Services AddRequestTimeouts Next apply request timeouts using middleware with UseRequestTimeouts app UseRequestTimeouts For specific endpoints use WithRequestTimeout timeout or add RequestTimeout timeout to the controller or action Keep in mind timeouts are cooperative When they expire HttpContext RequestAborted triggers but requests won t be forcibly stopped Your app should keep an eye on the token and decide when to wrap up request processing Quick Route Short CircuitIn this update Microsoft introduces a new option for quicker route handling Usually when a route matches an endpoint the middleware pipeline runs before invoking the endpoint logic However you might not need this for certain requests like robots txt or favicon ico Use the ShortCircuit option to immediately invoke the endpoint logic and end the request app MapGet gt Hello World ShortCircuit For quickly sending a or another status code without further processing try MapShortCircuit app MapShortCircuit robots txt favicon ico This efficient approach bypasses unnecessary features like authentication and CORS Blazor s Handy SectionsMicrosoft introduces SectionOutlet and SectionContent components in Blazor making it easy to create content placeholders in layouts These sections can later be filled by specific pages using unique names or object IDs For instance add a SectionOutlet to the top row of MainLayout in a Blazor template Don t forget to include the Microsoft AspNetCore Components Sections directive in the root Imports razor file using Microsoft AspNetCore Components Sections lt div class top row px gt lt SectionOutlet SectionName TopRowSection gt lt a href target blank gt About lt a gt lt div gt Now pages can display content in the TopRowSection using SectionContent In Counter razor you could add a button to increment the counter lt SectionContent SectionName TopRowSection gt lt button class btn btn primary onclick IncrementCount gt Click me lt button gt lt SectionContent gt Sections make organizing content a breeze	2023-04-21 12:41:42
