MODULE-1 Presented By : Indira Devi Garden City University | 2024  FULL STACK DEVELOPMENT OVERVIEW 1 Brief introduction to the concepts covered in the presentation: React, CSS, JavaScript, Web Development principles. Garden City University | 2024  2 INTRODUCTION React is a popular open-source JavaScript library developed by Facebook for building user interfaces, particularly single-page applications where efficiency and dynamic updates are vital. It allows developers to create reusable UI components, which helps in managing the view layer of web and mobile applications. React's primary feature is its use of a virtual DOM, which optimizes rendering by updating only parts of the DOM that have changed, rather than the entire page. This results in improved performance and a smoother user experience. React's component-based architecture encourages modularity, making code more maintainable and easier to debug, which is why it has become a preferred choice for developers in creating interactive web applications.

Garden City University | React Bootstrap Example: import Button from 'react-bootstrap/Button'; 2 Primary Button Traditional Bootstrap Example: Primary Button 2024 React Bootstrap provides pre-built React components, offering better integration with React’s declarative nature. Traditional Bootstrap requires you to use HTML classes and jQuery for dynamic components (like modals and carousels). React Bootstrap eliminates jQuery and focuses on the declarative approach React offers.  4 TYPES OF INPUT ELEMENTS IN HTML5 HTML5 introduced several new input types for better user experience and validation, such as email, date, and number Garden City University | 2024 Explanation: Email: Validates email format automatically. Number: Allows only numeric input, with optional range validation. Date: Provides a date picker for user-friendly date input.  5 CSS MODULES IN REACT Explanation CSS modules help prevent naming conflicts and make styling easier to manage in React components by using local scoped styles. CSS Modules ensure that class names are locally scoped to the component and don't clash with other components’ styles. In the example, Button.module.css ensures that the.button class is unique and scoped to the Buttoncomponent.  6 ES6 FEATURES - REACT Explanation ES6 features like Arrow Functions, Template Literals, and Destructuring improve readability and maintainability of React code. Arrow Functions: Simplify function definitions, especially for callbacks. Destructuring: Simplifies extracting properties from objects or arrays Example Arrow Function: const greet = (name) => `Hello, S{name}`; Destructuring: const user = { name: "John", age: 30 }; const { name, age } = user; ASYNC/AWAIT FOR ASYNCHRONOUS DATA FETCHING 7 Example: import { useState, useEffect } from 'react'; function FetchData() { const [data, setData] = useState(null); const fetchData = async () => { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); }; useEffect(() => { fetchData(); }, []); return {data ? JSON.stringify(data) : 'Loading...'}; } Garden City University | 2024  8 ARROW FUNCTIONS AND DESTRUCTURING IN REACT Arrow functions and destructuring help make React components more concise and readable. Arrow Functions: Destructuring: Garden City University | Simplify function expressions and Allows you to extract data from improve readability. objects or arrays, reducing the need for props.title and props.content. Example Example 2024 const handleClick = () => alert('Button const MyComponent = ({ title, content Clicked'); }) => ( {title} {content} );  9 RESPONSIVE DESIGN WITH MEDIA QUERIES Media queries are used to make the layout responsive, ensuring that the app works well on different screen sizes. Media queries allow you to apply different styles based on the viewport size. In React, you can conditionally render components or styles using media queries for a responsive design. GARDEN CITY UNIVERSITY | 202 4  CSS FLEXBOX AND GRID LAYOUTS IN REACT Flexbox and Grid are CSS layout systems used to create complex, responsive designs without floats or positioning. Flexbox A powerful one-dimensional layout system (for rows or columns). container { display: flex; justify-content: space-between; Grid } A two-dimensional system that allows you to create both rows and columns.React components can use these layouts for complex and responsive design structures..container { display: grid; grid-template-columns: 1fr 2fr; Garden City University | 2024 }  11 CSS ANIMATIONS AND TRANSITIONS IN REACT CSS animations and transitions enhance user interaction by adding dynamic visual effects. CSS Transitions: Smoothly transition between states (e.g., hovering over a button). CSS Animations: Keyframe-based animations for complex effects. This CSS code snippet includes a transition effect for a button that changes its background color smoothly when hovered over, and an animation that makes a box slide in from the left and fade in.  JSX IN REACT VS TRADITIONAL JAVASCRIPT 12 JSX (JavaScript XML) is a syntax extension for JavaScript that is commonly used with React to describe what the UI should look like.. It allows developers to write HTML-like code within JavaScript, making it easier to visualize the component structure.. In contrast, traditional JavaScript would require more verbose code to achieve the same UI description, often using methods like `document..createElement` or manipulating the DOM directly.. JSX simplifies the process by allowing you to describe the UI in a more declarative manner, while React handles the rendering and updates efficiently.. This declarative approach not only makes the code cleaner and easier to read but also leverages React's ability to efficiently update the UI by understanding the component's intended output.. JSX Example: Traditional JavaScript Example: const element = Hello, world!; ```javascript In this example, JSX allows you to write an const element = document.createElement('h1'); HTML `` tag directly within your JavaScript element.textContent = 'Hello, world!'; code. When this JSX code is compiled, it is ``` transformed into a `React.createElement` call Here, you explicitly create an HTML element and set that creates a React element. its text content, which is more cumbersome and !'; less intuitive than using JSX.

Development Often developed using JavaScript frameworks like React, Commonly built using server-side languages like PHP, Ruby, Angular, or Vue.js. or Java. User Experience Provides a seamless experience with fast transitions and May feel less seamless due to frequent page reloads, but minimal page reloads. can offer more straightforward navigation. SEO More complex to optimize for search engines; requires Generally easier to handle SEO as each page has its own URL additional tools or server-side rendering for better and metadata. indexing. Examples Gmail, Google Maps, Facebook Amazon, Wikipedia, eBay URL Structure Typically uses a single URL with dynamic content Each page has a unique URL, which can improve loading and hash-based navigation. bookmarking and sharing.  Garden City University | 2024 THANK YOU Presented By : C.Indira Devi
