There is no threshold time limit required for you to learn web development, however, different job roles will have different criteria for the level of experience needed for a role.

Breaking down the Web Development Roadmap further can make it more approachable for beginners.

Front-End vs. Back-End vs. Full-Stack Development

Your web application lives inside a suitable host environment, from where it is delivered to a client environment over TCP/IP in the following steps :

• Client or the “Front-End” makes an HTTP request to the host domain/IP with a request URL and some meta-data in form of HTTP headers.
• Server or “Back-End” receives the request and decides what type of response and metadata to send back to the client.
• The client receives a response and renders it as a webpage inside the browser tab.

So in the loading of a single webpage, the client initiates the transaction, the server validates the request and decides how to fulfill it, and finally, the client receives a response with which the data transaction is completed.

This separation of systems into Front-End and Back-End is the basis of understanding the Internet’s development, delivery, performance, and security landscape. Both in technical and conceptual terms.

The three types of web development are derived from this:

1. Back-End Development: Developing the core system that can receive requests, access databases, perform computation, and handle multiple clients simultaneously. It could be a static, dynamic, or hybrid system.
2. Front-End Development: This involves coding the responses received by clients, usually in the form of HTML pages with multiple dependencies, UI elements, hyperlinks, etc. It focuses on building an instance of the website/application that can be consumed in the client environment.
3. Full-Stack Developmen : Full-Stack Development refers to the comprehensive handling of both front-end and back-end development. A Full-Stack Developer has the skills to work on both the client-side and server side of the application, managing the complete data flow between the user and the server.

Each web development area has unique characteristics, advantages, and challenges. Choosing between Front-End, Back-End, or Full-Stack development depends on your project needs, career goals, or team structure.

• If you are more inclined toward visual design and user interaction, Front-End development might be for you.
• If you enjoy working on logical problems, handling data, web servers and server-side operations, Back-End development may be a suitable path.
• Full-Stack development offers that opportunity if you want to handle both aspects and comprehensively view the entire web development process.

Web Development Roadmap in 2023

If you’re looking to become a web developer, having a clear roadmap is essential to guide you through the myriad technologies and concepts you’ll need to understand.

All web developers have some things in common, but they’re also unique based on the problem they are working on and their approach to solving it.

Here are the common steps in a typical Web Development journey roadmap:

1. Learning Core Web Technologies

The first step is to learn the underlying core technologies that make up the world wide web and its contents. It includes: 

• Core Web Languages i.e. HTML, CSS and JS 
• Protocols like TCP/IP, HTTP/HTTPS, FTP, SMTP etc.
• Basics of Web Semantics, Accessibility, and Usability

2. Learn about types of Web Applications

Learn what types of applications are suitable for your use case, or if you are a student, understand the most commonly deployed types of applications on the web like:

• Static HTML pages: Web pages that have fixed content and display the same information to every visitor without any real-time interaction or updates.
• Dynamic HTML Pages: Web pages that can change content dynamically, often using JavaScript and other libraries, providing interactive and real-time user experiences.
• Server-Side Apps: Applications that run on the server and dynamically generate content, typically using languages like PHP, Python, or Java, which is sent to the client’s browser.
• Single Page Apps: Web applications that load a single HTML page and dynamically update content as the user interacts with the app, offering a smoother user experience.
• Progressive Web Apps: Web applications that provide a native-app-like experience on the web, with features like offline access, push notifications, and fast loading times.
• Hybrid Apps: Mobile applications built using web technologies that can run both on web browsers and as native apps on various mobile platforms, offering a blend of web and native functionalities.
