Web Development Internet Programming

Internet Programming Study Notes

Web Development

• Definition: The process of creating websites and web applications.
• Key Components:
  • Front-end: User interface and user experience (UI/UX).
  • Back-end: Server, database, and application logic.
• Development Tools: IDEs (Integrated Development Environments), version control (e.g., Git).
• Frameworks:
  • Front-end: React, Angular, Vue.js.
  • Back-end: Node.js, Django, Ruby on Rails.

Server-side Programming

• Definition: Code that runs on the server, handling requests and responses.
• Languages:
  • JavaScript (Node.js)
  • Python (Django, Flask)
  • Ruby (Ruby on Rails)
  • PHP
  • Java (Spring)
• Key Functions:
  • Database interaction (CRUD operations).
  • Authentication and authorization.
  • Business logic processing.

Web Technologies

• HTML: Structure of web pages.
• CSS: Styling and layout control.
• JavaScript: Client-side interactivity and dynamic content.
• Web Servers: Software that serves web pages (e.g., Apache, Nginx).
• Databases:
  • SQL (MySQL, PostgreSQL) for structured data.
  • NoSQL (MongoDB, Redis) for unstructured or semi-structured data.

Client-side Scripting

• Definition: Code executed in the user's browser.
• Primary Language: JavaScript, often enhanced with libraries (e.g., jQuery).
• Functions:
  • DOM manipulation to update content dynamically.
  • Event handling for user interactions.
  • AJAX for asynchronous data retrieval.

API Integration

• Definition: Connecting different software applications to communicate and share data.
• Types of APIs:
  • REST (Representational State Transfer): Stateless operations, uses standard HTTP methods (GET, POST, etc.).
  • SOAP (Simple Object Access Protocol): Protocol for exchanging structured information.
  • GraphQL: Flexible query language for APIs.
• Key Concepts:
  • Endpoints: URLs where APIs can be accessed.
  • Request methods: Defines actions (GET, POST, PUT, DELETE).
  • Authentication: Ensuring secure access (e.g., API keys, OAuth).

Summary

Internet programming encompasses web development which integrates front-end and back-end technologies, enabling dynamic user experiences. Server-side programming handles core functionality, while web technologies provide the necessary tools and frameworks. Client-side scripting enhances interactivity and user engagement, and API integration allows disparate systems to communicate efficiently.

Web Development

• Involves creating websites and web applications.
• Key components include front-end (UI/UX design) and back-end (server, database, application logic).
• Development tools are IDEs and version control systems like Git.
• Popular front-end frameworks: React, Angular, Vue.js.
• Notable back-end frameworks: Node.js, Django, Ruby on Rails.

Server-side Programming

• Refers to code executed on the server, managing requests and responses.
• Common programming languages: JavaScript (Node.js), Python (Django, Flask), Ruby (Ruby on Rails), PHP, and Java (Spring).
• Key server-side functions encompass database interactions (CRUD), authentication, authorization, and business logic processing.

Web Technologies

• HTML provides the structure of web pages.
• CSS is used for styling and layout control.
• JavaScript enables client-side interactivity and dynamic content.
• Web servers (e.g., Apache, Nginx) serve web pages to users.
• Databases facilitate data management, with SQL solutions (MySQL, PostgreSQL) for structured data and NoSQL solutions (MongoDB, Redis) for unstructured data.

Client-side Scripting

• Involves code executed within the user's browser.
• Primary language is JavaScript, frequently enhanced with libraries such as jQuery.
• Functions include DOM manipulation for dynamic content updates, event handling for user interactions, and AJAX for asynchronous data retrieval.

API Integration

• Represents the connection of different software applications for data sharing.
• Types of APIs include REST (stateless operations using HTTP), SOAP (structured information exchange), and GraphQL (flexible query language).
• Key concepts include endpoints (URLs for API access), request methods (actions like GET, POST, PUT, DELETE), and authentication mechanisms (such as API keys and OAuth).

Summary

• Internet programming integrates web development's front-end and back-end technologies, facilitating dynamic user experiences.
• Server-side programming underpins critical functionality while web technologies provide essential tools and frameworks.
• Client-side scripting boosts interactivity, and API integration streamlines communication between diverse systems.
