- 1. Introduction to Front-End Development Understanding the Fundamentals of Client-Side Web Development Chandrashekhar Chaurasiya Course: B.Tech/ CSE/ 4th Year/A Roll No: 2101200100054
- 2. What is Front-End Development? • Definition: Front-end development focuses on the part of the web that users interact with directly. • Technologies: HTML, CSS, JavaScript. • Key Points: • - Client-side development • - User experience (UX) & User interface (UI) • - Ensuring responsiveness and performance
- 3. Front-End vs Back-End • Front-End: UI/UX, Browsers, HTML, CSS, JavaScript, responsive design. • Back-End: Server-side, Databases, APIs, authentication.
- 4. Core Technologies of Front- End • HTML (HyperText Markup Language): Structure of a web page. • - Tags, elements, attributes. • - Example: <div>, <p>, <h1>. • CSS (Cascading Style Sheets): Styling and layout. • - Selectors, properties, media queries. • - Example: color: red;, flexbox, grid. • JavaScript: Adds interactivity. • - DOM manipulation, event handling, fetch API.
- 5. Popular Front-End Frameworks and Libraries • React: Component-based library by Facebook, JSX, virtual DOM. • Angular: Full-featured framework by Google, two- way data binding. • Vue.js: Progressive framework for building UIs. • Comparison Chart: • - React: Flexibility, large community. • - Angular: Full-featured, opinionated. • - Vue: Lightweight, easy to integrate.
- 6. Tools and Workflow • Version Control: Git & GitHub. • Task Runners & Build Tools: Gulp, Webpack, Parcel. • Package Managers: npm, Yarn. • Browser DevTools: Chrome/Firefox DevTools for debugging. • Responsive Design Tools: Figma, Sketch.
- 7. Responsive and Mobile-First Design • Definition: Adapting the layout to various screen sizes (desktop, tablet, mobile). • Media Queries: Example of a media query in CSS. • Frameworks: Bootstrap, Materialize CSS. • Mobile-First Approach: Designing for mobile screens first and progressively enhancing for larger screens.
- 8. Web Accessibility • Definition: Ensuring websites can be used by people with disabilities. • Best Practices: • - Alt text for images. • - ARIA roles and attributes. • - Keyboard navigability.
- 9. Performance Optimization • Key Techniques: • - Image optimization (lazy loading, compression). • - Minifying CSS/JS. • - Reducing HTTP requests. • - Using a Content Delivery Network (CDN).
- 10. Browser Compatibility • Challenges: Different browsers interpret code slightly differently. • Tools: CanIUse, Polyfills. • Best Practices: • - Writing cross-browser compatible code. • - Graceful degradation and progressive enhancement.
- 11. Front-End Development Process • Steps: • - Requirement gathering. • - Wireframing/Prototyping. • - UI/UX design. • - Development. • - Testing and Debugging.
- 12. Introduction to Web APIs • What is an API? • APIs allow front-end applications to communicate with back-end servers. • Examples: • - Fetch API to make HTTP requests. • - Geolocation API, Web Storage API.
- 13. Front-End Development Best Practices • Clean and Maintainable Code: Following a coding standard, using comments. • Modular Development: Breaking down UI components (React, Vue). • Testing: Unit tests (Jest), Integration tests, E2E tests (Cypress).
- 14. Career Opportunities in Front-End • Job Titles: • - Front-End Developer, UI/UX Developer, Web Developer. • Skills Required: Proficiency in HTML, CSS, JavaScript, frameworks (React, Angular, Vue). • Growing Demand: Importance of mobile and responsive design.
- 15. Conclusion • Front-end development is essential for creating interactive, user-friendly web experiences. • Understanding the core technologies (HTML, CSS, JavaScript) is critical. • Keep up with the latest trends and tools. • Next Steps: • - Explore frameworks (React, Angular). • - Practice building responsive and accessible websites.
