海外TECH	DEV Community	Tutorial: Internationalize Your Next.js Static Site (with App Router)	https://dev.to/rockystrongo/tutorial-internationalize-your-nextjs-static-site-with-app-router-34hp	Tutorial Internationalize Your Next js Static Site with App Router One of the amazing features that Next js offers is Static Export With static export enabled Next js generates static HTML CSS JS files based on your entire React application This approach has many benefits particularly for performance and SEO This also means that your app can be deployed and hosted on any web server that can serve HTML CSS JS static assets such as a simple and affordable nginx configuration While working with static exports one problem I came across is in and the ability to translate my app content into multiple languages I found very few online resources about this topic especially when working with the App Router introduced in Next js version Let s work together to create a basic internationalized app that demonstrates how to achieve this You can find the working demo project here  Step Initialize the projectTo create a new Next js project run the command below and follow the instructions npx create next app latestWe will use TypeScript Tailwind and App Router for the purpose of this example We can now start replacing the default project with the content of our application Our requirements are as follows  A Header with two links  Home and AboutA home page including the text Hello World An about page with the text This is a fully translated static website All texts should be translated in English and FrenchA language switcher should be available in the Header   Create a Header component  Create a components folder and a Header component components Header tsximport Link from next link export default function Header return lt div className bg gray w screen shadow gt lt nav className container flex px py gap gt lt Link href gt Home lt Link gt lt Link href about gt About lt Link gt lt nav gt lt div gt Update the homepage with Hello World app page tsxexport default function Home return lt div gt Hello World lt div gt Include the header in the app layout  app layout tsximport globals css import type Metadata from next import Header from components Header export const metadata Metadata title Create Next App description Generated by create next app export default function RootLayout children children React ReactNode return lt html lang en gt lt body className bg gray gt lt Header gt lt div className p gt children lt div gt lt body gt lt html gt Create the about page  app about page tsxexport default function AboutPage return lt div gt This application is a fully translated static website lt div gt Update the next config js file to enable static exportThanks to this config when running npm run build Next js will generate static HTML CSS JS files in the out folder type import next NextConfig const nextConfig output export module exports nextConfigAt this stage we have implemented the basic features of our app but we haven t incorporated any translation or in logic yet All the text is currently hardcoded Step internationalize the projectWe will be using the library next intl which is frequently maintained and popular in the Next js community It is mentioned in the Next js official documentation in the internationalization section npm install next intl Create translation filesFile messages en json Homepage helloWorld Hello World AboutPage aboutText This is a fully translated static website Header home Home about About File messages fr json HomePage helloWorld Bonjour tout le monde AboutPage aboutText Ceci est un site statique complètement traduit Header home Accueil about A propos Update the file structure├ーmessages​│├ーen json​│└ーfr json​└ーapp​ └ー locale ​ ├ーlayout tsx​ └ーpage tsx​ └ーlayout tsx​ └ーpage tsx​ └ーnot found tsx​First create the locale folder and move the existing page tsx file layout tsx file and the about folder inside it Do not forget to update the imports Create an app not found tsx file this will be our error page in case a user enters an incorrect url app not found tsxexport default function NotFound return lt div gt Custom Page lt div gt Create a new app layout tsx file  app layout tsximport ReactNode from react type Props children ReactNode Since we have a not found tsx page on the root a layout file is required even if it s just passing children through export default function RootLayout children Props return children create a new app page tsx file  In this page we redirect the users to the default language in our case English NOTE with static export no default locale can be used without a prefix We have to redirect incoming requests to the default language As explained in the docs app page tsximport redirect from next navigation export default function RootPage redirect en Update app locale layout tsx app locale layout tsximport globals css import type Metadata from next import Header from components Header import ReactNode from react import notFound from next navigation import NextIntlClientProvider from next intl type Props children ReactNode params locale string export const metadata Metadata title Create Next App description Generated by create next app function to get the translationsasync function getMessages locale string try return await import messages locale json default catch error notFound function to generate the routes for all the localesexport async function generateStaticParams return en fr map locale gt locale export default async function RootLayout children params locale Props const messages await getMessages locale return lt html lang en gt lt body className bg gray gt lt NextIntlClientProvider locale locale messages messages gt lt Header gt lt div className p gt children lt div gt lt NextIntlClientProvider gt lt body gt lt html gt What we have done here  Add a getMessages function to get the translationsAdd a generateStaticParams function to generate the static routes for all the localesAdd the context provider NextIntlClientProvider to make our translations available in all of the app pages Update the pages components to use the translations app page tsx use client import useTranslations from next intl export default function HomePage const t useTranslations HomePage return lt div gt t helloWorld lt div gt What we have done here  Add use client as of today translations with next intl are only supported in client components Import the useTranslations hook and use it in our jsxApply the same to other pages components  app locale about page tsx use client import useTranslations from next intl export default function AboutPage const t useTranslations AboutPage return lt div gt t aboutText lt div gt components Header tsx use client import Link from next link import useTranslations from next intl export default function Header const t useTranslations Header return lt div className bg gray w screen shadow gt lt nav className container flex px py gap gt lt Link href gt t home lt Link gt lt Link href about gt t about lt Link gt lt nav gt lt div gt Update the links to take into account the locale prefixInstead of using the Link provided by Next js or the element always use the component next intl link provided by next intl  components Header tsx use client import Link from next intl link import useTranslations from next intl export default function Header const t useTranslations Header return lt div className bg gray w screen shadow gt lt nav className container flex px py gap gt lt Link href gt t home lt Link gt lt Link href about gt t about lt Link gt lt nav gt lt div gt If you run your app you will notice that you are immediately redirected from http localhost to http localhost enThe header links are taking into account the en prefix If you change it from en to fr you will see your website translated in French We are almost done  All is left in our requirement list is the local switcher Step    Add a locale switcher Create the necessary translations File messages en json LocaleSwitcher locale locale select fr French en English other Unknown File messages fr json LocaleSwitcher locale locale select fr français en anglais other inconnu This syntax from next intl will help us to implement a multiple value select switcher You can find the documentation for message syntax here rendering messages Create a locale switcher component components LocaleSwitcher tsx use client import useLocale useTranslations from next intl import usePathname useRouter from next intl client export default function LocaleSwitcher const t useTranslations LocaleSwitcher const locale useLocale const router useRouter const pathname usePathname const onLocaleChange e React ChangeEvent lt HTMLSelectElement gt gt const newLocale e target value router replace pathname locale newLocale return lt select defaultValue locale onChange onLocaleChange gt en fr map lang gt lt option key lang value lang gt t locale locale lang lt option gt lt select gt As a last step add the locale switcher to the Header component and the job is done  Our static application is internationnalized To build the app run  npm run buildThe static export is generated in the out folder Test the generated output by running  npx serve latest outThrough the combination of Next js s features the App Router and the next intl library you ll create performant SEO friendly and language friendly web applications that reach a global user base Embrace internationalization and elevate your Next js projects to new heights	2023-07-30

海外TECH	DEV Community	Frontend And Backend Understanding the Differences	https://dev.to/amarachi_kanu_20/frontend-and-backend-understanding-the-differences-12i4	Frontend And Backend Understanding the Differences IntroductionIn the case of web development two essential concepts that often arise are frontend and backend development Frontend is client side and backend is server side These concepts refer to distinct aspects of building websites and applications Understanding the differences between frontend and backend development is important for anyone interested in pursuing a career in web development or for those who want to understand better how websites and applications are built Some backend developers still do a lot of frontend work or vice versa What is Frontend Development Being a frontend developer is so exciting you re at the forefront so to speak and directly impact how the user feels about and interacts with the product or service that the websites you build portray Frontend is all the visual things seen on the webpage images texts and buttons The visual elements that users see and interact with within a web application are implemented by it It combines two different elements the graphic design the look and the user interface the feel Each of these is created independently with most of the technical work going into creating a user interface that is responsive accessible and engaging using web languages like HTML CSS and JavaScript The frontend world is big Key technologies in frontend developmentFrontend development plays a great role in shaping website and application user experience and interface By mastering HTML CSS and JavaScript along with essential skills like responsive design and collaboration frontend developers can create engaging and user friendly digital experiences Staying updated with emerging trends and adopting best practices ensures that frontend developers can adapt to the ever evolving landscape of web development delivering exceptional user experiences Here are some technologies used in frontend development HTMLHTML which stands for Hypertext Markup Language is the standard markup language for creating web pages and applications It provides the structure and content of a webpage defining the elements and their relationships within the document You can create headings paragraphs links images forms etc It is the foundation of web development and understanding HTML is essential for building web content HTML is the foundation of web development providing the structure and content for webpages It uses tags elements and attributes to define a document s various components and relationships It is necessary for creating well structured accessible and search engine friendly web content CSSCSS which stands for Cascading Style Sheets is a styling language used to describe HTML elements presentation and visual appearance on a web page It allows web developers to control the layout colors fonts and other visual aspects of a website or application It works by applying styles to HTML elements using selectors properties and values With CSS you can create responsive designs apply animations and transitions and customize the look and feel of a webpage CSS plays a role in enhancing the user experience and creating visually appealing web content JavaScriptJavaScript is a versatile programming language that adds interactivity and dynamic functionality to web pages It is commonly used in frontend development but can also be employed on the backend Node js JavaScript allows developers to manipulate webpage elements handle user interactions and perform calculations It supports features like variables functions conditionals loops and objects making it a powerful language for building interactive web applications With JavaScript you can create form validations perform AJAX requests create animations and more It enhances user experiences and adds functionality to websites and web applications What is Backend Development Backend development focuses on the server side of a website or application It involves handling the behind the scene functionality such as server configuration database management and application logic Backend developers often work with programming languages like Python Ruby Java or PHP to create the logic and infrastructure that support the frontend Key technologies in backend developmentHere are some key technologies in backend development These technologies server side programming languages web frameworks and databases form the core of backend development which enables the creation of robust and functional server side components for web applications and software systems Server side programming languagesBackend development involves using programming languages like Python Java Ruby PHP or Node js to create the server side logic that handles data processing business logic and communication with databases and other services Web frameworksBackend web frameworks provide a structured approach to building web applications Examples include Django Python Ruby on Rails Ruby Spring Java Laravel PHP and Express js Node js These frameworks simplify development tasks and promote code organization and maintainability DatabasesBackend developers use databases like MySQL PostgreSQL MongoDB NoSQL or Redis an in memory database to store and manage data It is important for persistent data storage and retrieval in web applications The Relationship between Frontend and BackendFrontend and backend development are components that cannot be separated A well designed and interactive frontend will only be meaningful with a backend to handle data process user requests and provide content Similarly a backend would only have a purpose with a visually appealing frontend for users to interact with To enable collaboration between the frontend and backend APIs are important APIs Application Programming Interfaces allow frontend and backend components to communicate and exchange data Frontend developers make HTTP requests to the backend APIs which then process the requests perform necessary operations and return the results to the frontend Key differences between Frontend and BackendLocation of Execution The primary difference between frontend and backend development is where the code is executed Frontend code is executed on the user s device client side within their web browser On the other hand backend code runs on the server server side that hosts the website or application User Interaction Frontend development is responsible for creating the visual elements and features that users directly interact with such as buttons forms and animations Backend development focuses on processing and handling user inputs such as form submissions and retrieving or storing data in databases Technologies and Languages Frontend developers use HTML CSS JavaScript and various frameworks like React Angular or Vue js to build responsive and interactive user interfaces Backend developers work with various programming languages including but not limited to Python Ruby Java Node js and PHP depending on the project s requirements They also work with databases like MySQL MongoDB or PostgreSQL to manage data Responsibilities Frontend developers are responsible for ensuring the websites or applications visual appeal usability and performance They need to optimize for different devices and browsers making the user experience consistent across platforms Backend developers focus on the application s functionality ensuring that data is processed accurately and that the server responds efficiently to frontend requests ConclusionIn summary frontend and backend development complement each other to
