Web Development
Web development refers to the process of creating and maintaining websites and web applications. It involves several disciplines, including:
1. Front-End Development:
- HTML (HyperText Markup Language): The standard markup language used to create web pages. It structures the content on the web.
- CSS (Cascading Style Sheets): Used for styling HTML elements, defining layout, colors, fonts, and other visual aspects of a web page.
- JavaScript: A programming language that enables interactive features on websites, such as animations, form validation, and dynamic content updates.
- Front-End Frameworks/Libraries:
- React: A JavaScript library for building user interfaces, especially single-page applications.
- Angular: A platform and framework for building single-page client applications using HTML and TypeScript.
- Vue.js: A progressive JavaScript framework for building user interfaces.
2. Back-End Development:
- Server-Side Languages:
- Node.js: JavaScript runtime for executing server-side code.
- Python: Often used with frameworks like Django or Flask.
- Ruby: Typically used with the Ruby on Rails framework.
- PHP: A widely-used open-source server-side scripting language.
Databases:
- SQL (Structured Query Language): Used for managing and querying relational databases (e.g., MySQL, PostgreSQL).
- NoSQL Databases: Used for non-relational databases (e.g., MongoDB).
- Back-End Frameworks:
- Express.js: A minimal and flexible Node.js web application framework.
- Django: A high-level Python web framework.
- Laravel: A PHP framework for web artisans.
3. Full-Stack Development:
- Involves both front-end and back-end development. A full-stack developer is proficient in working with both the client-side and server-side technologies.
4. Web Design:
- UI/UX Design: Focuses on the user interface (UI) and user experience (UX) to create visually appealing and user-friendly websites.
- Responsive Design: Ensures that websites work well on a variety of devices and screen sizes, using techniques like fluid grids, flexible images, and media queries.
5. Web Development Tools:
- Version Control: Tools like Git for tracking changes in code.
- Build Tools: Tools like Webpack, Gulp, and Grunt for automating tasks.
- Package Managers: Tools like npm (Node Package Manager) and Yarn for managing project dependencies.
6. Web Hosting and Deployment:
- Hosting Services: Platforms like AWS, Heroku, and Netlify for deploying web applications.
- CI/CD (Continuous Integration/Continuous Deployment): Automating the process of testing and deploying code.
7. Security:
- HTTPS/SSL: Ensuring secure communication over the web.
- Authentication and Authorization: Implementing secure login and user access control.
- OWASP: Following security best practices to protect against vulnerabilities.
- Web development is a dynamic field that continually evolves with new technologies, tools, and best practices. Whether you’re interested in building the visual interface, managing server-side logic, or working across the entire stack, there are many opportunities to specialize and grow in this area.
Web development refers to the creating, building, and maintaining of websites. It includes aspects such as web design, web publishing, web programming, and database management. It is the creation of an application that works over the internet i.e. websites.
The word Web Development is made up of two words, that is:
- Web: It refers to websites, web pages or anything that works over the internet.
- Development: It refers to building the application from scratch.
Web Development can be classified into two ways:
- Frontend Development
- Backend Development
Frontend DevelopemntThe part of a website where the user interacts directly is termed as front end. It is also referred to as the ‘client side’ of the application.
Popular Frontend Technologies
- HTML: HTML stands for HyperText Markup Language. It is used to design the front end portion of web pages using markup language. It acts as a skeleton for a website since it is used to make the structure of a website.
- CSS: Cascading Style Sheets fondly referred to as CSS is a simply designed language intended to simplify the process of making web pages presentable. It is used to style our website.
- JavaScript: JavaScript is a scripting language used to provide a dynamic behavior to our website.
- Bootstrap: Bootstrap is a free and open-source tool collection for creating responsive websites and web applications. It is the most popular CSS framework for developing responsive, mobile-first websites. Nowadays, the websites are perfect for all browsers (IE, Firefox, and Chrome) and for all sizes of screens (Desktop, Tablets, Phablets, and Phones).
Backend Development
Backend is the server side of a website. It is part of the website that users cannot see and interact with. It is the portion of software that does not come in direct contact with the users. It is used to store and arrange data.
Backend Roadmap
Popular Backend Technologies
- PHP: PHP is a server-side scripting language designed specifically for web development.
- JavJava is one of the most popular and widely used programming languages. It is highly scalable.
- Python: Python is a programming language that lets you work quickly and integrate systems more efficiently.
- Node.js: Node.js is an open source and cross-platform runtime environment for executing JavaScript code outside a browser.
Databases
In web technology, a database is a structured collection of data that is stored electronically and accessed via a web application. It serves as the backend component where data is stored, managed, and retrieved. Databases can be relational (like MySQL, PostgreSQL) using structured tables and SQL for queries, or non-relational (like MongoDB, CouchDB) which store data in flexible, document-oriented formats. They enable web applications to handle dynamic content, user data, transactions, and more by providing efficient storage, retrieval, and manipulation capabilities. Database management systems (DBMS) are used to interact with the database, ensuring data integrity, security, and performance.
Databases
Relational Database
A relational database stores data in tables, similar to a spreadsheet, where each table has rows and columns. The rows hold individual records, and the columns define the data attributes. Tables can be linked to each other through special keys, allowing related data to be connected.
- Postgre SQL: PostgreSQL is a powerful, open-source relational database that supports advanced SQL features and complex queries. It handles structured data, ensures ACID compliance, and is known for its reliability and extensibility.
- MariaDB: MariaDB is an open-source relational database that evolved from MySQL, offering improved performance, security, and features. It supports SQL queries, ACID compliance, and is highly compatible with MySQL.
- MySQL: MySQL is an open-source relational database management system that uses SQL for managing structured data. It’s known for its reliability, ease of use, and performance, widely used in web applications.
NoSql Database
A NoSQL database stores data in a flexible, non-tabular format, unlike traditional relational databases. Instead of using tables with rows and columns, NoSQL databases might use documents, key-value pairs, wide-columns, or graphs to store data. This allows them to handle large amounts of unstructured or semi-structured data efficiently. They are designed to scale easily and manage big data applications.
- Mongodb: MongoDB is a NoSQL database storing data in JSON-like documents. It handles unstructured data, supports powerful queries, and scales easily across servers, making it popular for flexible, scalable applications.
- Cassandra: Apache Cassandra is an open-source NoSQL database that is used for handling big data. It has the capability to handle structure, semi-structured, and unstructured data.
