Web Development

▎Common Backend Development Terms

1. Server: A computer or system that provides data, resources, or services to other computers (clients) over a network.

2. Database: An organized collection of data that can be easily accessed, managed, and updated. Common databases include MySQL, PostgreSQL, MongoDB, and SQLite.

3. API (Application Programming Interface): A set of protocols and tools that allows different software applications to communicate with each other, often exposing endpoints for data interaction.

4. REST (Representational State Transfer): An architectural style for designing networked applications that use HTTP requests to access and manipulate data, typically in JSON or XML format.

5. GraphQL: A query language for APIs that allows clients to request only the data they need, providing a more efficient and flexible alternative to REST.

6. Middleware: Software that acts as a bridge between different applications or services, often handling requests and responses in web applications.

7. Authentication: The process of verifying the identity of a user or system, often using methods like passwords, tokens, or OAuth.

8. Authorization: The process of determining whether a user or system has permission to perform a specific action or access certain resources.

9. Session Management: The technique used to manage user sessions in web applications, allowing users to stay logged in and maintain state across multiple requests.

10. Microservices: An architectural style that structures an application as a collection of small, loosely coupled services, each responsible for a specific business function.

11. Monolithic Architecture: A traditional software architecture where all components of an application are combined into a single, unified codebase.

12. CRUD (Create, Read, Update, Delete): The four basic operations of persistent storage, representing the fundamental functions of a database.

13. ORM (Object-Relational Mapping): A programming technique used to convert data between incompatible type systems in object-oriented programming languages, allowing developers to interact with databases using objects instead of SQL queries.

14. Web Server: A server that handles HTTP requests from clients, serving web pages and resources. Examples include Apache, Nginx, and Microsoft IIS.

15. Load Balancer: A device or software that distributes network or application traffic across multiple servers to ensure reliability and performance.

16. Caching: The process of storing copies of files or data in temporary storage locations to reduce latency and improve performance in data retrieval.

17. Continuous Integration/Continuous Deployment (CI/CD): A set of practices that enable developers to automatically test and deploy code changes to production environments quickly and reliably.

18. Version Control: A system that tracks changes to code over time, allowing developers to collaborate effectively and manage different versions of their applications, commonly using tools like Git.

19. Containerization: A method of packaging an application and its dependencies into a container that can run consistently across different computing environments, often using tools like Docker.

20. Serverless Computing: A cloud computing model where the cloud provider automatically manages the infrastructure required to run applications, allowing developers to focus on writing code without worrying about server management.

▎Additional Common Node.js Terms

1. REPL (Read-Eval-Print Loop): An interactive programming environment that takes single user inputs, executes them, and returns the result to the user, often used for testing snippets of code.

2. EventEmitter: A core class in Node.js that allows objects to emit events and listen for them, facilitating event-driven programming.

3. Child Process: A module in Node.js that allows the creation of child processes to execute shell commands or run other Node.js scripts concurrently.

4. CORS (Cross-Origin Resource Sharing): A security feature implemented in web browsers that restricts web pages from making requests to a different domain than the one that served the web page, often configured in Node.js applications.

5. dotenv: A popular Node.js package used to load environment variables from a .env file into process.env, simplifying configuration management.

6. WebSocket: A protocol that provides full-duplex communication channels over a single TCP connection, enabling real-time data transfer between clients and servers.

7. Body Parser: A middleware function in Express.js that parses incoming request bodies and makes the data available under req.body, commonly used for handling form submissions.

8. Rate Limiting: A technique used to control the number of requests a client can make to a server within a certain time frame, helping to prevent abuse and overload.

9. Authentication: The process of verifying the identity of a user or service, often implemented using strategies like JWT (JSON Web Tokens) or OAuth in Node.js applications.

10. Authorization: The process of determining whether a user has permission to perform a specific action or access certain resources after authentication has been completed.

11. Logging: The practice of recording application events and errors for monitoring and debugging purposes, often implemented using libraries like winston or morgan.

12. Static Files: Files served directly by the web server without any processing, such as HTML, CSS, JavaScript, images, and fonts, often handled by middleware in Express.js.

13. Proxy: A server that acts as an intermediary for requests from clients seeking resources from other servers, commonly used for load balancing and security.

14. Template Engine: A library used to generate HTML dynamically by embedding JavaScript code into HTML templates, examples include EJS, Pug, and Handlebars.

15. Session Management: The process of storing user session data on the server side to maintain state across multiple requests, often using libraries like express-session.

16. API Gateway: A server that acts as an entry point for client requests to various microservices, handling routing, authentication, and request aggregation.

17. Microservices: An architectural style where an application is composed of small, independent services that communicate over APIs, allowing for better scalability and maintainability.

18. Load Balancer: A device or software that distributes network traffic across multiple servers to ensure no single server becomes overwhelmed, improving performance and reliability.

19. Debugging Tools: Software tools used to test and debug Node.js applications, such as Chrome DevTools, Node Inspector, and Visual Studio Code's built-in debugger.

20. Deployment Pipeline: A set of automated processes that allow developers to build, test, and deploy applications consistently and reliably across different environments.
