Supercharge team productivity with Husky, ESLint, and Prettier

<div><h3> Introduction </h3> In the ever-evolving world of software development, maintaining code quality and consistency is crucial for successful team collaboration. As projects grow in complexity and involve multiple developers, the risk of introducing bugs, inconsistent coding styles, and maintainability issues increases. Fortunately, modern tools and practices have emerged to address these challenges, enabling teams to work more efficiently and deliver high-quality code. In this blog post, we'll explore the power of tools like Husky, ESLint, Prettier, and more, and how they can enhance your team's development workflow. <h3> The Importance of Code Quality and Consistency </h3> Code quality and consistency are essential for any software project, but they become even more critical when working in a team environment. Poorly written or inconsistent code can lead to increased technical debt, making it harder for developers to understand, maintain, and extend the codebase over time. This, in turn, can significantly impact team productivity and project timelines. Overlooked errors and style inconsistencies can also introduce bugs and make it challenging to collaborate effectively. Imagine a situation where one developer follows a specific coding style, while another has a different approach. This can make code reviews more time-consuming and increase the risk of merge conflicts, ultimately slowing down the development process. Fortunately, automated tools can help teams enforce coding standards, identify potential issues, and maintain a consistent codebase across the entire project. <h3> Introducing Husky: The Pre-Commit Hook Powerhouse </h3> Husky is a powerful tool that allows you to run scripts before committing code or pushing changes to a remote repository. It's particularly useful for enforcing code quality checks and preventing developers from accidentally committing code that doesn't adhere to the team's coding standards. With Husky, you can define pre-commit hooks that run specific scripts before each commit. For example, you could set up a pre-commit hook that runs ESLint (a code linting tool) and Prettier (a code formatting tool) to ensure that your code is free of errors and follows consistent styling conventions. <ul> <li> Setting up Husky in Your Project </li> </ul> <div class="highlight js-code-highlight"> <pre class="highlight javascript"><code># Using npm npm install husky --save-dev # Using yarn yarn add husky --dev </code></pre> </div> By using pre-commit hooks with Husky, you can catch potential issues early in the development process, reducing the risk of introducing bugs and maintaining a clean, consistent codebase. <h3> Enforcing Code Quality with ESLint: The JavaScript Linting Powerhouse </h3> ESLint is a powerful tool for identifying and fixing problems in JavaScript code. It can help teams enforce coding standards, detect potential bugs, and promote best practices, ensuring that the codebase remains maintainable and easy to understand. <ul> <li> Setting up ESLint in Your Project </li> </ul> <div class="highlight js-code-highlight"> <pre class="highlight javascript"><code># Using npm npm install eslint --save-dev # Using yarn yarn add eslint --dev </code></pre> </div> ESLint provides a wide range of rules that can help you catch potential issues, such as unused variables, missing semicolons, inconsistent naming conventions, and more. By enforcing these rules across your codebase, you can maintain a consistent coding style and prevent common coding mistakes, ultimately improving code quality and maintainability. <h3> Ensuring Code Consistency with Prettier: The Code Formatting Guru </h3> While ESLint focuses on code linting and identifying potential issues, Prettier is a tool designed specifically for code formatting. It helps teams maintain a consistent coding style by automatically formatting code according to predefined rules. <ul> <li> Integrating Prettier into Your Workflow </li> </ul> <div class="highlight js-code-highlight"> <pre class="highlight javascript"><code># Using npm npm install prettier--save-dev # Using yarn yarn add prettier --dev </code></pre> </div> <div class="highlight js-code-highlight"> <pre class="highlight javascript"><code>module.exports = { semi: true, singleQuote: true, trailingComma: 'all', printWidth: 80, // Add more rules as needed }; </code></pre> </div> By enforcing consistent code formatting across your codebase, Prettier reduces the cognitive load for developers when reading and reviewing code. It also helps eliminate unnecessary code style discussions during code reviews, allowing teams to focus on more important aspects of the codebase. <h3> Combining Husky, ESLint, and Prettier: The Ultimate Team Development Trifecta </h3> While each of these tools is powerful on its own, combining them can create a seamless and efficient development workflow that ensures code quality and consistency at every step. By combining these powerful tools, you can create a streamlined development workflow that promotes code quality and consistency from the very beginning, reducing technical debt and making it easier for team members to collaborate and maintain the codebase over time. <h3> Additional Tools and Best Practices </h3> While Husky, ESLint, and Prettier are powerful tools for enforcing code quality and consistency, they are just a few examples of the many tools and practices that can enhance your team's development workflow. Here are a few additional tools and best practices to consider: <ol> <li>TypeScript: TypeScript is a superset of JavaScript that adds static typing to the language. By using TypeScript, you can catch type-related errors during development, improving code quality and maintainability.</li> <li>Tailwind CSS: Tailwind CSS is a utility-first CSS framework that can help teams maintain consistent styling across their projects. It provides a set of pre-defined utility classes that can be used to style components, reducing the need for custom CSS and promoting a more consistent UI.</li> <li>Folder Structure and Organization: Maintaining a well-organized and consistent folder structure is crucial for large projects with multiple team members. By following best practices for folder structure and organization, you can make it easier for developers to navigate and understand the codebase.</li> <li>Pair Programming: Pair programming is a practice where two developers work together on the same code, taking turns as the "driver" (who writes the code) and the "navigator" (who reviews and provides guidance). This practice can help catch issues early, promote knowledge sharing, and ensure that code is written following agreed-upon standards and best practices.</li> <li>Version Control: Using a version control system like Git is essential for team collaboration and maintaining a clear history of code changes. By following best practices for branching strategies, pull requests, and merge workflows, teams can ensure that code changes are reviewed, tested, and merged consistently.</li> </ol> <h3> Real-World Applications and Benefits </h3> The benefits of using tools like Husky, ESLint, and Prettier, and implementing best practices for code quality and consistency are not just theoretical; they have been proven time and again in real-world projects. <blockquote> At @<a href="https://dev.to@creowis/">CreoWis</a> , we developed an open-source template repository using Next.js, TypeScript, Tailwind CSS, Husky, Prettier, and ESLint.

Why React is Both a Library and a Framework (And You’re Not Wrong to Say It’s a Framework)

<div>I wrote this article as a result of a discussion (I won't call it an argument because it occurred in a learning platform and we're all learning) - React is a Library, or React is a framework. I've been working with React for quite sometime and all the Devs I've worked with usually just call it a framework. And personally, I see it as a framework myself. I was surprised to see some folks saying that's wrong and it's just a Library. This article I believe should do a bit of expo to that, and if you have any reservation, feel free to comment. In the world of JavaScript, one debate that continues to persist is whether React is a library or a framework. Officially, React is described by its creators at Facebook (now Meta) as a "JavaScript library for building user interfaces." However, if you've heard someone call it a framework, they aren't necessarily wrong. In this article, we’ll break down the reasons why React can be seen as both a library and a framework, and clarify the difference between a JavaScript library and a JavaScript framework. What is a JavaScript Library? A JavaScript library is a collection of pre-written JavaScript code that helps developers solve common problems and build features more easily. A library provides tools to perform specific tasks, but it leaves the developer in control of the application’s structure and architecture. For example: <ul> <li> React is often referred to as a UI library because it allows developers to build reusable UI components without dictating how the rest of the application should be built.</li> <li> Lodash is a popular JavaScript utility library that provides functions for tasks like working with arrays, objects, and strings. Lodash doesn’t dictate how your project should be structured; it just provides tools you can use where necessary.</li> </ul> In a library, the developer calls the library. This means the developer decides when and where to use the library's functions. What is a JavaScript Framework? A JavaScript framework, on the other hand, is a full-fledged toolset that dictates much more about how you should build your application. Frameworks provide a structured and opinionated approach to development, offering a complete solution for building applications. In a framework, the framework calls the developer’s code, not the other way around. This distinction is referred to as "inversion of control." Frameworks provide default configurations, and the developer fills in the gaps by writing specific logic where needed. For example: <ul> <li> Angular is a framework that enforces a particular structure and pattern, such as using components, services, and a module system.</li> <li> Vue.js, although lighter and more flexible, still qualifies as a framework because it provides an end-to-end solution for building user interfaces and applications.</li> </ul> Frameworks are often seen as being "opinionated" because they come with rules about how you should structure your code, enforce patterns, and offer tools to handle routing, state management, and more. Why React is a Library React is officially described as a library because: <ul> <li> It is focused on one specific task: building user interfaces.</li> <li> React does not impose a specific structure or architecture on your application. You can use React as little or as much as you need without adopting an entire ecosystem or specific conventions.</li> <li> Unlike frameworks like Angular or Vue, React doesn’t come with built-in tools for routing, state management, or making HTTP requests. Developers can add these features by using additional libraries (like React Router for routing or Redux for state management).</li> </ul> Essentially, React provides components and a way to render them efficiently. It doesn’t care how the rest of your application is organized, making it more flexible and modular than a traditional framework. Why React is also a Framework While React is a library at its core, calling it a framework is not entirely wrong either. Here’s why: React Ecosystem: <ul> <li>In practice, many developers use React alongside additional libraries and tools to build full applications, including React Router (for navigation), Redux (for state management), and Next.js (for server-side rendering). These tools combined create a full-fledged development experience, much like a traditional framework.</li> <li>The React ecosystem has grown to the point where you can build entire applications using only React-centric tools. Once you're immersed in the React way of doing things, it can feel just like using a framework.</li> </ul> Inversion of Control: <ul> <li>While React doesn’t force you into a particular architecture, it does take control over rendering the UI and managing component states. This "inversion of control" characteristic is a hallmark of frameworks.</li> <li>React components dictate when they render and how their states change over time. The React lifecycle methods, hooks like <code>useEffect</code>, and the virtual DOM management are part of how React controls parts of your application.</li> </ul> Developer Experience: <ul> <li>The fact that React often requires the use of a set of libraries (often React-specific) to build a complete application puts it in a similar category as a framework. When most developers think about using React, they are thinking not just about the core library but about the surrounding ecosystem of tools.</li> <li>Popular frameworks like Next.js, which is built on top of React, offer an all-encompassing structure that feels very framework-like, giving developers routing, server-side rendering, and static site generation—all using React.</li> </ul> Community and Conventions: <ul> <li>Over the years, the React community has developed conventions and best practices around React development, such as the use of hooks, JSX, and component-based architecture. These conventions help streamline development and make React behave like a framework by providing guidance on how applications should be structured.</li> </ul> Full Application Development: <ul> <li>With the introduction of tools like React Native (for mobile apps) and Next.js (for server-side rendered React apps), React has evolved beyond just a UI library. These tools allow developers to build full applications across different platforms, which aligns more with what frameworks traditionally offer.</li> </ul> Library vs. Framework: A Grey Area The line between library and framework isn’t always clear. As we’ve seen with React, a tool can exhibit characteristics of both depending on how it's used. This grey area is common in modern JavaScript development, where the ecosystem is modular, and tools can grow beyond their original purposes. <ul> <li> React, as a core tool, is a library that focuses on UI.</li> <li> However, the ecosystem around React and its conventions provide the framework-like structure for building full applications.</li> <li> When someone calls React a framework, they’re acknowledging the broad scope and ecosystem React offers, which resembles the capabilities of a framework.</li> </ul> Final Thoughts Whether you call React a library or a framework depends largely on how you use it and the surrounding tools. What’s most important is recognizing that React can scale from a lightweight, flexible UI library to a powerful tool that acts as a framework in real-world applications. So next time someone tells you React is "just a library," feel free to point out that it might just be a framework, too—depending on how you look at it.</div>

Comprehensive Step-by-Step Guide to Setting Up a Next.js Project

<div>Next.js is one of the most popular frameworks for building modern web applications. Built on top of React.js, Next.js offers server-side rendering, static site generation, file-based routing, and other powerful features to streamline the web development process. 1. What is Next.js? Before diving into the setup, it’s crucial to understand what makes Next.js different from other React frameworks: <ul> <li>Server-Side Rendering (SSR): Pages are pre-rendered on the server, enhancing performance and SEO.</li> <li>Static Site Generation (SSG): Pre-renders pages at build time for lightning-fast performance.</li> <li>File-Based Routing: Routes are automatically generated based on the files in the pages directory.</li> <li>API Routes: Define backend endpoints directly within the same Next.js project.</li> <li>Full Stack Capabilities: Supports hybrid static & server-side rendering, with a flexible deployment system.</li> </ul> 2. Setting Up a Next.js Project Next.js is constantly evolving, and in 2024, it’s easier than ever to set up and start building your application. Step 1: Prerequisites Ensure that you have the following prerequisites installed: Node.js: Version 18.x or higher. You can check your version by running: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>node -v </code></pre> </div> If you don't have Node.js, download it from <a href="https://www.nodejs.org/" rel="noopener noreferrer">nodejs.org</a>. npm or yarn: npm comes bundled with Node.js, but you can also use yarn as a package manager if preferred. Step 2: Creating a New Next.js Project Next.js provides a command-line tool called create-next-app that streamlines the setup process. <ol> <li>Navigate to the folder where you want to create your project: </li> </ol> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>cd /path/to/your/directory </code></pre> </div> <ol> <li>Run the command to create a Next.js app: If you're using <code>npm</code>, run: </li> </ol> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>npx create-next-app@latest </code></pre> </div> For yarn, use: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>yarn create next-app </code></pre> </div> Follow the prompts: <ul> <li> Project Name: Give your project a name (e.g., nextjs-app).</li> <li> Typescript: Decide whether to use TypeScript or JavaScript.</li> <li> ESLint: Enable or disable linting (recommended to enable).</li> <li> Tailwind CSS: You can choose to add Tailwind CSS during the setup, or add it later manually.</li> <li> Import Alias: Decide whether to configure import aliases for cleaner file imports.</li> </ul> After this, the Next.js starter project will be created with all the essential configurations. Step 3: Exploring the Folder Structure Once your project is created, the structure will look like this: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>nextjs-app/ ├── node_modules/ ├── pages/ │ ├── api/ │ │ └── hello.js │ ├── _app.js │ ├── index.js ├── public/ ├── styles/ │ ├── globals.css │ ├── Home.module.css ├── .eslintrc.json ├── next.config.js ├── package.json └── README.md </code></pre> </div> <ul> <li> pages/: This is where the routes and page components are defined.</li> <li> pages/api/: API routes are stored here; <code>hello.js</code> is an example.</li> <li> public/: Static assets (e.g., images, fonts) are placed here.</li> <li> styles/: Global and module-specific stylesheets.</li> </ul> Step 4: Running the Development Server Navigate into your project directory: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code> cd nextjs-app </code></pre> </div> Start the development server: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code> npm run dev </code></pre> </div> or <div class="highlight js-code-highlight"> <pre class="highlight shell"><code> yarn dev </code></pre> </div> This will start the Next.js server at <a href="http://localhost:3000/" rel="noopener noreferrer">http://localhost:3000</a>. You can now open your browser and visit <a href="http://localhost:3000/" rel="noopener noreferrer">http://localhost:3000</a> to see the default Next.js page. 3. Core Features of Next.js A. File-Based Routing Next.js uses a file-based routing system, meaning every file in the <code>pages/</code> directory automatically becomes a route. <ul> <li>Create a new page:</li> </ul> Create a new file called about.js inside the <code>pages/</code> directory: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code> touch pages/about.js </code></pre> </div> <ul> <li>Add the following content to the file: </li> </ul> <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code> const About = () => { return <h1>About Us</h1>; } export default About; </code></pre> </div> Access the page: Open your browser and visit <a href="http://localhost:3000/about" rel="noopener noreferrer">http://localhost:3000/about</a>, and you’ll see the content from the About component. B. Linking Between Pages Next.js comes with a built-in Link component to handle client-side navigation. Modify your index.js file to include a link to the About page: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code> import Link from 'next/link'; const Home = () => { return ( <div> <h1>Welcome to the Home Page</h1> <Link href="/about">Go to About Page</Link> </div> ); }; export default Home; </code></pre> </div> Now, when you click on the "Go to About Page" link, you will be routed to the about page. C. CSS and Styling in Next.js Next.js allows you to import CSS files globally or use CSS modules for component-level styles. Global CSS: In the styles/globals.css file, you can add global styles: <div class="highlight js-code-highlight"> <pre class="highlight css"><code> body { font-family: Arial, sans-serif; margin: 0; } </code></pre> </div> Import this file in your _app.js component: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code> import '../styles/globals.css'; function MyApp({ Component, pageProps }) { return <Component {...pageProps} />; } export default MyApp; </code></pre> </div> CSS Modules: For component-specific styles, Next.js supports CSS Modules. Modify Home.module.css: <div class="highlight js-code-highlight"> <pre class="highlight css"><code> .title { color: red; } </code></pre> </div> Then, import it in your index.js file: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code> import styles from '../styles/Home.module.css'; const Home = () => { return <h1 className={styles.title}>Welcome to the Home Page</h1>; }; export default Home; </code></pre> </div> 4. Data Fetching in Next.js Next.js offers multiple ways to fetch data for pages. A. Static Site Generation (SSG) Pre-render the page at build time by using the getStaticProps function: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code> export async function getStaticProps() { const res = await fetch('https://api.example.com/data'); const data = await res.json(); return { props: { data } }; } const Home = ({ data }) => { return ( <div> <h1>Data from API:</h1> <pre>{JSON.stringify(data, null, 2)}</pre> </div> ); }; export default Home; </code></pre> </div> B. Server-Side Rendering (SSR) Fetch data at request time using the getServerSideProps function: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code> export async function getServerSideProps() { const res = await fetch('https://api.example.com/data'); const data = await res.json(); return { props: { data } }; } const Home = ({ data }) => { return ( <div> <h1>Server-Side Data:</h1> <pre>{JSON.stringify(data, null, 2)}</pre> </div> ); }; export default Home; </code></pre> </div> 5. API Routes in Next.js Next.js allows you to define backend routes within the same project. These routes are created inside the <code>pages/api/</code> folder. Create a file called hello.js inside <code>pages/api/</code>: <div class="highlight js-code-highlight"> <pre class="highlight javascript"><code> export default function handler(req, res) { res.status(200).json({ message: 'Hello from Next.js API!' }); } </code></pre> </div> Access the API endpoint at <a href="http://localhost:3000/api/hello" rel="noopener noreferrer">http://localhost:3000/api/hello</a>. 6. Deployment in Next.js Next.js projects can be deployed on various platforms like Vercel, Netlify, or any Node.js server. Here's how to deploy on Vercel: Install Vercel CLI: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code> npm install -g vercel </code></pre> </div> Deploy: From your project directory, run: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code> vercel </code></pre> </div> PS: Localhost is not a URL you can access over the internet; it only works on your local computer. It refers to the server running on your machine, typically at <a href="http://localhost/" rel="noopener noreferrer">http://localhost</a>, and is used for development purposes.</div>

Mastering TypeScript with React: A Step-by-Step Guide

<div><h2> 🙋🏻‍♀️ Introduction </h2> TypeScript adds static typing to JavaScript, which helps catch potential bugs before they even run. When paired with React, TypeScript enhances your components by enforcing type safety. In this article, we'll walk through the essential concepts for using TypeScript with React. <h2> ⚛️ How to Use TypeScript with React? </h2> First, you need to install TypeScript in a React project. If you're starting from scratch, create a new React app with TypeScript enabled: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>npx create-react-app my-app --template typescript </code></pre> </div> For an existing project, you can add TypeScript by running: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>npm install typescript @types/react @types/react-dom </code></pre> </div> Now, you can start using <code>.tsx</code> files instead of <code>.js</code> or <code>.jsx</code>, and your React components will benefit from TypeScript’s features. <h2> Types for React Component Props </h2> When you’re defining a component in React, you can specify the types for its props to make the usage of the component clearer and safer. Here’s a basic example: <div class="highlight js-code-highlight"> <pre class="highlight tsx"><code>type UserProps = { name: string; age: number; }; const UserCard = ({ name, age }: UserProps) => ( <div> <h1>{name}</h1> <p>{age} years old</p> </div> ); </code></pre> </div> In this example, <code>UserCard</code> expects two props: <code>name</code> (a string) and <code>age</code> (a number). If you try to pass incorrect types, TypeScript will show an error. <h2> ReactNode Vs ReactElement </h2> You might wonder when to use <code>ReactNode</code> or <code>ReactElement</code> for typing React components. <ul> <li>ReactNode: Represents anything that can be rendered by React. This includes strings, numbers, JSX, arrays, and <code>null</code>.</li> <li>ReactElement: Refers to an actual React element, which is more specific and doesn’t cover strings or <code>null</code>.</li> </ul> Example: <div class="highlight js-code-highlight"> <pre class="highlight tsx"><code>type CardProps = { children: ReactNode; }; const Card = ({ children }: CardProps) => <div>{children}</div>; // Usage <Card><p>Hello, World!</p></Card> </code></pre> </div> <code>ReactNode</code> is used here because <code>children</code> can be any renderable element, not just React elements. <h2> Type Vs Interface </h2> When defining the shape of props or other objects, both <code>type</code> and <code>interface</code> can be used. So, what’s the difference? <ul> <li> Type: Best for creating union types or more complex combinations.</li> <li> Interface: Often better when you plan to extend or implement additional types.</li> </ul> Here’s a comparison: <div class="highlight js-code-highlight"> <pre class="highlight tsx"><code>// Using type type ButtonProps = { label: string; onClick: () => void; }; // Using interface interface LinkProps { href: string; openInNewTab?: boolean; } </code></pre> </div> While both are similar, <code>interface</code> can be extended more naturally: <div class="highlight js-code-highlight"> <pre class="highlight tsx"><code>interface IconButtonProps extends ButtonProps { icon: string; } </code></pre> </div> <h2> How to Type Props with TypeScript? </h2> To type props for a component, declare a <code>type</code> or <code>interface</code> and pass it as the type annotation for the component's props. Example: <div class="highlight js-code-highlight"> <pre class="highlight tsx"><code>type AlertProps = { message: string; severity: 'error' | 'warning' | 'info'; }; const Alert = ({ message, severity }: AlertProps) => ( <div className={`alert ${severity}`}>{message}</div> ); </code></pre> </div> <h2> How to Type Functional Component Props? </h2> To type a functional component's props, you can use <code>React.FC<Props></code> or declare the props explicitly. While <code>React.FC</code> was commonly used, now many prefer explicit types. Here’s an example using explicit types: <div class="highlight js-code-highlight"> <pre class="highlight tsx"><code>type BadgeProps = { text: string; color: string; }; const Badge = ({ text, color }: BadgeProps) => ( <span style={{ backgroundColor: color }}>{text}</span> ); </code></pre> </div> In this example, <code>Badge</code> has two props, <code>text</code> and <code>color</code>, both typed as strings. <h2> ⛓ React Hooks with TypeScript </h2> React hooks can also be typed in TypeScript to ensure type safety for the state and effect logic in your components. Here’s how to use <code>useState</code> and <code>useEffect</code> with TypeScript: <div class="highlight js-code-highlight"> <pre class="highlight tsx"><code>import { useState, useEffect } from 'react'; const Counter = () => { const [count, setCount] = useState<number>(0); useEffect(() => { console.log(`Count is: ${count}`); }, [count]); return ( <div> <button onClick={() => setCount(count + 1)}>Increment</button> <p>Count: {count}</p> </div> ); }; </code></pre> </div> In this example, the <code>useState</code> hook is typed to ensure <code>count</code> is always a number, and <code>useEffect</code> logs the current count whenever it changes. By following these best practices, you’ll be able to harness the full potential of TypeScript in your React applications, leading to more robust, maintainable code.

Here are 5 effective ways to make API request in Reactjs

<div>Data fetching is a core aspect of dynamic and responsive applications in modern web development. <a href="https://react.dev/" rel="noopener noreferrer">Reactjs</a> is a popular frontend library, which offers several ways to fetch and manage data. Whether you’re building a simple app or a complex large app, It’s important to understand the various methods you can use to fetch data in react While building a large and complex application, it is considered best practice to keep your files and folders clean and more organized way to avoid duplication and navigate easily and understandable. There are many ways but, I’m sharing with you the most popular way. Learn more about <a href="https://programmingly.dev/atomic-design-pattern-how-to-set-up-your-reactjs-project-structure/" rel="noopener noreferrer">Setting up your Reactjs project structure by using atomic design pattern</a>. In this article, I’m going to share 5 different methods for fetching data from servers using RESTful API in reactjs: <ul> <li>Fetch API</li> <li>Axios</li> <li>React Query</li> <li>SWR</li> <li>GraphQL (Apollo Client)</li> </ul> If you’re curious about native javascript ways, read this article on <a href="https://mroman7.medium.com/here-are-5-different-ways-to-make-api-calls-in-javascript-e6636ceba288" rel="noopener noreferrer">making API calls in javascript in 5 different ways</a>. 1) Fetch API The Fetch API is a modern & built-in javascript function for making asynchronous calls. It’s a native browser API that returns a promise. The Fetch API is built on top of javascript promises which makes handling requests much easier and cleaner to write. Here is an example of fetching data in reactjs using Fetch API: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code>import React, { useEffect, useState } from "react"; export default function PostsListWrapper() { const [posts, setPosts] = useState([]); const [loading, setLoading] = useState(true); const getPosts = () => { return fetch("https://jsonplaceholder.typicode.com/posts") .then((response) => response.json()) .then((data) => { setPosts(data); setLoading(false); }) .catch((error) => console.error("Error: ", error)); }; useEffect(() => { getPosts(); }, []); if(loading) return <p>Loading...</p> return ( <section> <h3>Posts List</h3> <ul>{posts && posts?.map((item, idx) => <li key={item.id}>{item.title}</li>)}</ul> </section> ); } </code></pre> </div> 2) Axios <a href="https://axios-http.com/" rel="noopener noreferrer">Axios</a> is the most popular third-party library for making asynchronous calls, based on javascript promises. Axios is simpler, faster, and much more powerful than native Fetch API, it provides control over our HTTP request. Some of the best features I love that make it unique and powerful, such as, <ul> <li>easy syntax</li> <li>creating different instances</li> <li>configure request</li> <li>playing with interceptors (middleware) to manipulate data in request and response</li> <li>retry or cancel the request</li> <li>handling errors</li> <li>and many others</li> </ul> In order to use axios in the react application, you need to install it as a dependency. Run the below command to install Axios: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>npm i axios </code></pre> </div> Let’s see Axios in action: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code>import React, { useEffect, useState } from "react"; // import axios import axios from "axios"; // defining a base url const BASE_URL = "https://jsonplaceholder.typicode.com"; // creating an instance const publicInstance = axios.create({ baseURL: BASE_URL, }); export default function PostsListWrapper() { const [posts, setPosts] = useState([]); const [loading, setLoading] = useState(true); const getPosts = async () => { try { let posts = await publicInstance({ url: "/posts", method: "GET", }); setLoading(false); setPosts(posts?.data); } catch (error) { console.log("Error: ", error); } }; useEffect(() => { getPosts(); }, []); if (loading) return <p>Loading...</p>; return ( <section> <h3>Posts List</h3> <ul> {posts && posts?.map((item, idx) => <li key={item.id}>{item.title}</li>)} </ul> </section> ); } </code></pre> </div> 3) React Query React Query is a powerful data-fetching and state management library that handles caching, automatic prefetching, providing request status (loading, success, fetching, error, and more), and many other useful features that we have to manage manually. React Query library is built by TenStack, they build multiple useful and powerful react libraries like these to make work easier and faster. If you’re interested, take a quick start guide of react-query by following <a href="https://tanstack.com/query/latest/docs/framework/react/quick-start" rel="noopener noreferrer">this link</a>. You need to install the react-query as a third-party dependency to your react app to start using it. Use the below command to install react-query, and devtools to see requests in action. <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>npm i @tanstack/react-query @tanstack/react-query-devtools </code></pre> </div> Here is an example of how to use React Query: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code>import React from 'react'; import { useQuery } from 'react-query'; import axios from 'axios'; const fetchPosts = async () => { const { data } = await axios.get('https://jsonplaceholder.typicode.com/posts'); return data; }; export default function PostsListWrapper() { const { data, error, isLoading, isSuccess } = useQuery('posts', fetchPosts); if (isLoading) return <p>Loading...</p>; if (error) return <p>Error fetching data.</p>; return ( <div> <h1>Posts</h1> {data.map((post) => ( <div key={post.id}> <h2>{post.title}</h2> <p>{post.body}</p> </div> ))} </div> ); }; </code></pre> </div> 4) SWR SWR (Stale While Revalidate) is a react hook-based library for making asynchronous calls. This library is created and maintained by Vercel (Company behind Nextjs) It focuses on cache management, revalidation, and minimal API requests. SWR is a strategy to first return the data from the cache (stale), then send the fetch request (revalidate), and finally come up with the up-to-date data. [by, <a href="https://swr.vercel.app/" rel="noopener noreferrer">SWR</a>] Like react-query, it caches data, revalidates provides request status (loading, success, error). The reason it is recommended is because it is: <ul> <li>lightweight</li> <li>easy syntax</li> <li>fast</li> <li>provides real-time experience</li> <li>and SSR / ISR / SSG ready</li> </ul> You can install SWR using the below command: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>npm i swr </code></pre> </div> Let’s understand it with an example in action: <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>import React from 'react'; import useSWR from 'swr'; const fetcher = (url) => fetch(url).then((res) => res.json()); export default function PostsListWrapper() { const { data, error, isLoading } = useSWR('https://jsonplaceholder.typicode.com/posts', fetcher); if (isLoading) return Loading...; if (error) return Error fetching data.; return ( <div> <h1>Posts</h1> {data.map((post) => ( <div key={post.id}> <h2>{post.title}</h2> {post.body} </div> ))} </div> ); }; </code></pre> </div> 5) GraphQL with Apollo Client GraphQL is becoming a new standard for making API calls. It provides efficient data handling and state management. GraphQL on its own is a big topic, so I’ll try to keep it simple and short. GraphQL is like a query language for APIs, it means instead of RESTful API which provides all the field values and keys, GraphQL allows the frontend to request exactly the data they need in a single request. This reduces the over-fetching and unnecessary data. Apollo Client on the other hand is a state management library that integrates with GraphQL. It is like a wrapper around GraphQL in our app which simplifies the process of fetching, caching, and managing data in client applications. It works with many different frameworks like React, Vue, Angular, and others. <a href="https://www.apollographql.com/docs/react/#community-integrations" rel="noopener noreferrer">See the Full list of supported frameworks</a>. In order to use it in your react app, install the below command: <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>npm install @apollo/client graphql </code></pre> </div> See Apollo GraphQL in action: <div class="highlight js-code-highlight"> <pre class="highlight jsx"><code>import React from 'react'; import { useQuery, gql } from '@apollo/client'; const GET_POSTS = gql` query GetPosts { posts { id title body } } `; export default function PostsListWrapper() { const { loading, error, data } = useQuery(GET_POSTS); if (loading) return <p>Loading...</p>; if (error) return <p>Error fetching data</p>; return ( <div> <h1>Posts</h1> {data.posts.map((post) => ( <div key={post.id}> <h2>{post.title}</h2> <p>{post.body}</p> </div> ))} </div> ); }; </code></pre> </div> This blog is originally posted at <a href="https://programmingly.dev/" rel="noopener noreferrer">Programmingly.dev</a>.

What is Behavior Driven Development (BDD)?

Introduction What is bdd ? Behavior Driven Development (BDD) is an agile software development methodology that emphasizes collaboration among all stakeholders—developers, testers, and business analysts—to create a shared understanding of the behavior of a software application. BDD extends Test Driven Development (TDD) by focusing on the behavior of the application from the end user's perspective. It uses natural language constructs to describe the expected behavior, making it accessible to non-

UI Libraries in React

<div>UI libraries that can create aesthetically pleasing websites are what every developer looks for. These libraries not only help developers but also make life easier for users by enabling them to navigate the system quickly. So, what are some great UI libraries that developers can use with React.js? Let’s see them one by one. Before that, it’s imperative to understand what React UI component libraries are. These libraries are *collections of pre-coded user-interface elements. * The elements included in component libraries are buttons, cards, tables, etc. Ultimately, they help developers ensure quick development and prototyping. Now, let’s see some of the best React UI Component Libraries. Chakra UI It’s one of the simpler UI libraries loved by almost every developer because of its modular and accessible components. It is built on top of React UI primitives. Moreover, to ensure that all components are accessible, Chakra UI uses WAI-ARIA guidelines. Some pros of using Chakra UI include: <ul> <li>Responsive components</li> <li>Availability of stack components</li> <li>Dark mode</li> <li>Multiple color modes</li> <li>Custom values</li> </ul> But why should you use it over others? Chakra UI's main focus is accessibility. This ensures that the app you build is usable by everyone. Additionally, it emphasizes simplicity. This might also be why it’s popular. As of today, Chakra UI has more than 37k stars on GitHub. Prime React Another library that developers love to use is PrimeReact. It is an open-source front-end library that helps in building responsive websites. However, for beginners, it’s challenging to learn. Some also call it the underdog because it’s not very popular. Part of the reason might be marketing. On GitHub, it has 6.1k stars. Why do I love this library? Developers don’t need to install extra packages to accomplish tasks. They can do a lot with just the library. Some pros of using PrimeReact include: <ul> <li>Data table components</li> <li>Customizable templates and themes</li> <li>Responsiveness</li> <li>Better accessibility</li> </ul> NextUI Another library that is popular in React.js is NextUI. It is renowned for its flexible nature and performance. NextUI is particularly recommended for building landing pages quickly. Moreover, NextUI offers immediate styling and components that developers can use after making some edits. It’s built on top of TailWind CSS and React Aria. Some advantages of NextUI include: <ul> <li>Gentle learning curve</li> <li>Use of high-quality and customizable components</li> <li>Adherence to WAI-ARIA guidelines</li> <li>Well-scaled default dark theme</li> <li>Lazy loading (helpful for app performance)</li> <li>Support for internationalization</li> <li>Form validation</li> </ul> Semantic UI If you prefer a library that is full of pre-built components then you need to use semantic UI. Some of the advantages of using Semantic UI include: <ul> <li>Auto-controlled state</li> <li>Shorthand props</li> <li>Augmentation</li> <li>Customization of themes</li> <li>Community support</li> </ul> Ant Design If you want to build enterprise applications, then go for Ant Design. This is because this UI library has many features that can make applications accessible as well as scalable. In fact, the reason it is too popular is because it has good performance and accessibility. Moreover, it gives developers the ability to tailor design elements as well. There are varying internalisation tools, too. The best part about Ant Design is that it enables the creation of a minimalist website. Ant Design focuses more on simplicity and consistency. <ul> <li>Typescript friendly</li> <li>Comprehensive</li> <li>Best (if you have to take a lot of input)</li> <li>Variety and customization</li> <li>Thorough documentation</li> </ul></div>
