Web Development Fundamentals

Web Development

Overview

• Web development refers to the process of building and maintaining websites, web applications, and mobile applications
• Involves multiple areas of expertise, including design, development, testing, and deployment

Front-end Development

• Focuses on client-side development, dealing with user interface and user experience
• Uses programming languages like HTML, CSS, and JavaScript
• Frameworks and libraries:
  • React, Angular, and Vue.js for building dynamic user interfaces
  • Bootstrap and Materialize for styling and layout
• Tasks:
  • Building responsive and interactive web pages
  • Creating reusable UI components
  • Implementing accessibility and usability features

Back-end Development

• Focuses on server-side development, dealing with data storage, processing, and retrieval
• Uses programming languages like Java, Python, Ruby, and PHP
• Frameworks and libraries:
  • Node.js with Express.js for building scalable server-side applications
  • Django and Ruby on Rails for rapid development and prototyping
• Tasks:
  • Building RESTful APIs for data exchange
  • Creating database schema and performing CRUD (Create, Read, Update, Delete) operations
  • Implementing authentication and authorization mechanisms

Full-stack Development

• Involves working on both front-end and back-end development
• Requires knowledge of both client-side and server-side technologies
• Tasks:
  • Building complete web applications from scratch
  • Integrating front-end and back-end components
  • Troubleshooting and debugging application issues

Databases

• Types:
  • Relational databases (e.g., MySQL, PostgreSQL)
  • NoSQL databases (e.g., MongoDB, Cassandra)
  • Graph databases (e.g., Neo4j)
• Tasks:
  • Designing database schema and performing data modeling
  • Performing database operations (CRUD)
  • Ensuring data consistency and integrity

Security

• Importance:
  • Protecting user data and preventing unauthorized access
  • Ensuring secure data transmission and storage
• Best practices:
  • Validating user input and sanitizing data
  • Implementing encryption and access controls
  • Regularly updating and patching software components
