Your Front-End Development Journey Begins Here

Welcome to the start of an exciting journey in front-end development! I'm thrilled guiding you step-by-step from the very basics to advanced concepts and frameworks. In this blog series, I will break down complex topics into manageable, easy-to-understand posts published weekly. (For more Context please read this post).

Each post is designed to build on the previous one, ensuring you develop a solid foundation before moving on to more advanced topics. Together, we'll explore the essential skills and knowledge needed to become a proficient front-end developer.

Get ready to dive deep, ask questions, and apply what you learn. By the end of this series, you'll not only have a comprehensive understanding of front-end development but also the confidence to create your own web projects. Let's embark on this learning adventure together!

Stage 0: Foundations of Web Development

Before we start learning HTML or CSS and before we dive into meta frameworks, we need to build a foundation for our journey. How can you be a good front-end developer if you don't know what HTTP is? How will you handle caching if you've never heard of a CDN? Hypothetically, if you build a website, how will the world find a route to your servers?

Unfortunately, many new front-end developers today jump straight into learning React. They often skip the basic concepts that are crucial for a solid understanding of web development. These foundational topics are essential for becoming a skilled front-end developer, yet they are often overlooked in favor of popular choices.

Kids this days!

This might seem a bit tedious at times, but this is where the distinction between a good and a bad front-end developer is made. I assure you, this line becomes more bold and significant as you progress in your journey. As you get deeper into front-end development, the importance of these basics will become increasingly clear.

  • How does the internet work? - (web pages, networking and web servers)

  • How we talk to each other? - (ip, dns, tcp, HTTP, browsers)

  • Who are you? - (protocol, domain, tld, url)

  • Where are you? - (vps/v ds hosting, edge computing)

Stage 1: HTML - The Backbone of Web Pages

We, as front-end developers, are responsible for creating user-friendly and accessible interfaces. Our journey begins with HTML, which serves as the backbone of any web page. HTML provides the fundamental structure, much like the skeleton of a body, upon which everything else is built. It defines the layout and organizes the content, ensuring that the page is both readable and navigable. This initial step is crucial, as it sets the stage for creating well-structured, accessible, and efficient web pages that meet the needs of all users.

  • Html basics

  • Html tags

  • Semantic elements (plus a little bit of seo)

  • Accessibility

  • Forms and validation

Well, it's not a lot, but it's crucial, especially accessibility. Later, you will understand what I'm talking about and why I'm emphasizing it so much.

Stage 2: CSS - Bringing Life to Web Pages

Without CSS, it is possible to have web pages, but they would look like primitive cave paintings. CSS, or Cascading Style Sheets, brings life and vibrancy to web pages by allowing us to style and layout our HTML content. It enables us to define colors, fonts, spacing, and positioning, transforming a plain HTML structure into a visually appealing and human-friendly interface.

CSS also plays an important role in ensuring that web pages are responsive and adaptable to different screen sizes and devices, providing a consistent experience for all users.

  • CSS basics

  • Selectors and naming conventions

  • Units and variables

  • Box sizing and positioning

At this point, we won't worry about the responsiveness of our pages yet. We will practice and create some beautiful web pages.

Stage 3: JavaScript Basics - Adding Interactivity

Alright, now that we have a basic understanding of how the web works, along with foundational knowledge of HTML and CSS, we can move on to creating our first interactive web page. This is where JavaScript (JS) comes into play. JavaScript is a powerful scripting language that allows us to add interactivity and dynamic behavior to our web pages.

With JavaScript, we can create features like image sliders, interactive maps and much more. It enables us to manipulate the page content (HTML or CSS), respond to user actions, and communicate with servers to fetch or send data.

To get started, we will:

  • Basics of JavaScript syntax and structure

  • Dom and Dom manipulation

  • Fetch and Fetch api

  • Event handling in respond to user actions

By the end of this stage, you will be able to build web pages that not only look good but also engage users with interactive features. This will set the foundation for more advanced JavaScript concepts and frameworks that we will explore later.

Stage 4: Advanced CSS - Enhancing Styling Skills

Now that we have a solid foundation in HTML, CSS, and JavaScript, it's time to further enhance our skills. In this step, we will focus more on styling. As a front-end developer, being skilled in styling is essential.

We will also cover responsive design, ensuring you can create pages that look good on any screen size or device. This means your web pages will automatically adjust and rearrange their layout to provide an optimal viewing experience, whether they are viewed on a desktop, tablet, or smartphone.

In this stage, we will dive deeper into CSS by learning:

  • Flex and Grid

  • Animations and Transitions:

  • Responsive Design

  • Advanced Selectors and Pseudo-Classes

By the end of this stage, you will have a comprehensive understanding of advanced CSS techniques. You will be able to create web pages that are not only aesthetically pleasing but also highly functional and responsive. This will significantly improve your front-end development skills and prepare you for tackling more complex projects in the future.

For historical context, we might also learn about CSS preprocessors like Sass and Less. They are still widely used in the industry, even though modern tools like Tailwind are more popular.

Stage 5: Advanced JavaScript - Deepening Your Knowledge

Alright, here we are. We have reached the gates of modern front-end development. Learning React or Next.js begins here. In this stage, we will move beyond just templates (HTML & CSS) and dive deep into JavaScript. before we start learning modern frameworks its necessary to learn more about JS.

in this stage we will learn about:

  • Asynchronousity

  • Class and objects (OOP)

  • Modules

  • Scripts (Npm, Yarn, ...)

  • JS runtime environments (like v8)

  • Debugging

  • DOM diffing

  • State and stitching state to DOM

I should mention that these topics are not all you should learn. There are many other subjects like TypeScript, bundling, and more that we will cover later at the appropriate time.

Learning TypeScript is beneficial for new web developers because it adds static types to JavaScript, helping catch errors early and making code easier to maintain. Its strong typing system and tools improve productivity and code quality, and it's widely used in the industry, enhancing job opportunities. Mastering TypeScript leads to more robust, scalable, and professional code, setting you apart in web development.

While I admit that these subjects may seem overwhelming (and let's be honest, a bit strange and scary), learning them is essential.

This i the way

This is going to be challenging, but you are going to become a fantastic front-end developer.

Stage 6: Pre-React Essentials

In this step, we will dive into and practice several important subjects that are crucial before starting to learn React. These subjects include GIT, Tailwind CSS, and a bit of VSCode customization (don't be worry by the way, i will convert you to that guy who lives in arch and codes in neovim, just give me the required amount of time and you will be the wizard)

In this stage we will learn more about the following subjects

  • Tailwind CSS

  • GIT

  • VS code and its ecosystem

Stage 7: Mastering React

React is a web development library. For many years it was just a front-end library, but in recent year, with the introduction of many server-side features, it is becoming more and more of a full-stack framework.

If you choose to step in this road, next years of your life would get dedicated to learning and digging deeper in react ecosystem.

Heads up!
React is a library with over a decade of history. It's widely used in the industry, and many solutions and use cases have developed around it. Today, React is not just a web framework. By learning React, you can create web apps, mobile apps, and even desktop apps that can run on most operating systems. However, it's important to note that learning React alone is not enough to develop apps for other platforms. You also need to learn other tools like React Native, Expo, Electron and many more!

This are going to be the subjects that we will learn:

  • Components and their life cycle

  • JSX and templates in react

  • Hooks and state management

  • Different Styling methods

  • Rendering

  • Routing

  • Forms

  • Testing and bundling

  • UI libraries (Shadcn, Headless UI, ...)

Stage 8: Exploring Meta Frameworks - Next.js

After we learned about react we will continue our journey with Next. Next.js is built on top of React, enhancing it with additional features and optimizations. It is often considered the next step for React developers who want to build more robust and scalable applications.

Next.js provides server-side rendering, static site generation, and API routes, making it a powerful tool for creating dynamic and high-performance web applications. It simplifies many of the complexities involved in setting up a React project, offering built-in support for routing, data fetching, and more.

By mastering Next.js, you will be able to build full-fledged applications that are not only efficient but also SEO-friendly and fast. This stage of learning will involve diving deep into the features and capabilities of Next.js, understanding how it extends React, and exploring best practices for building modern web applications.

There are many other alternatives to Next.js, like Remix.js. I personally prefer Remix because it relies on standard web APIs and has fewer magical elements. However, since Next.js is widely adopted across the industry, you have more access to learning materials and better chances of finding a job.

in this stage we will learn about the following subjects:

  • Routing, Navigation and pages (api, layouts, middlewares, ...)

  • Data fetching and catching

  • Rendering paradigms (CSR, SSR, SSG, ISR)

  • Client/Server paradigms

  • Authentication and security

  • Asset optimization (images, fonts, ...)

  • Streaming, Error handling and debugging

  • SEO

  • internationalization

  • Edge runtime
