React for Beginners: A Practical Guide for Web Publishers

Can you work with HTML/CSS, but find React difficult?

First Steps in React for Web Publishers! From Building a Responsive Shopping Mall to Deployment

Can you build webpages with HTML and CSS and know some JavaScript, but feel overwhelmed about where to start with React?

New concepts such as components, Props, State, and Hooks may feel unfamiliar.

This course is designed for those who want to learn React based on their existing web publishing experience.

Starting with familiar HTML/CSS, you will learn the core syntax of React and ultimately complete a fully functional, responsive shopping mall website.

Rather than simply following syntax and examples, you’ll experience the React development process by implementing the entire website interface yourself.

🛒 First, check out the project you’ll complete!

By the end of the course, you will have completed a responsive shopping mall website featuring a product list, search and filtering, sorting, pagination, and more.

Experience the completed shopping mall project firsthand

Explore the project yourself to preview the features you’ll implement in this course.

Key Features to Implement

• Product List: Display product data fetched from an external JSON API using React components

• Product filtering: Browse products using various criteria such as category, brand, and price

• Product sorting: Sort the product list according to your preferred criteria

• Pagination: Display product data across multiple pages

• Responsive web: Configure the screen layout to suit PC and mobile environments

• Website deployment: Publish the completed project using Vercel

In this course, you will apply React’s core concepts, such as components, Props, State, events, and list rendering, in practice.

💡 What will you learn?

STEP 01. Understanding React from a Publisher’s Perspective

Learn why you should learn React and how it differs from traditional web publishing methods.

• Comparison of Traditional HTML/CSS/JavaScript and React Development Approaches

• Setting Up a React Development Environment with Vite

• Understanding JSX Syntax and Components

• Passing Data Using Props

• Implementing Dynamic UIs Using State and Events

STEP 02. Applying Existing Web Publishing Skills to React

Expand your familiar HTML/CSS authoring experience into React component development.

• Display the appropriate screen based on the situation with conditional rendering

• Rendering repeated elements using map and key

• Utilizing CSS Modules and Global Styles

• Image and Icon Management

• Resolving Common Errors That Occur During Development

STEP 03. Implementing a Responsive Shopping Mall with React

Apply what you have learned so far to an actual shopping mall UI.

• Configuring a Common Header and Menu

• Creating a Reusable Product Card Component

• Fetch product data and display it as a list

• Implementing a UI using events and state management

• Responsive design that accounts for various screen sizes

Rather than simply creating the final product, this section focuses on the process of converting web publishing work into a React project.

STEP 04. Implementing Features Required for a Real Online Shopping Mall

Implement product browsing functionality using React’s data processing and state management features.

• Integrating Product Data Using a JSON API

• Filtering using category, brand, and price criteria

• Product sorting

• Implementing pagination

• State Management Basics Using Context API

In the process of implementing each feature, you’ll see how React’s core syntax is used in a real-world project.

STEP 05. Deploying the Completed Project

Perform a final review and deploy the shopping mall website you created.

• Review the Entire Project’s Code and Structure

• Check the Implemented Features

• Website deployment using Vercel

• Explore the direction of your next steps in frontend learning

✅ After completing the course, you will be able to do the following.

• You can leverage existing HTML/CSS-based web publishing experience in React development.

• You can understand core concepts such as JSX, components, props, and state.

• You can build web pages using reusable React components.

• You can display and process data fetched via an API on the screen.

• You can implement practical features such as product filtering, sorting, and pagination.

• You can create and deploy responsive React websites.

Ultimately, you will have a React shopping mall project that you implemented yourself as a finished portfolio piece.

Key Learning Content and Features 📚

Practical, industry-style instruction 📘

Rather than simply learning React syntax, you will implement the entire main page of a website as if it were a real project. As you build the project, you will learn how to write the HTML structure needed for implementation by referring to the design, how to write CSS styles that match the design, and how to write scripts according to the required functionality, in that order.

Creating and Implementing a React Project 📘

Create a project using React, then implement it using HTML, CSS, and React (JavaScript).

Implement filtering and sorting 📘

Based on what you learned in the React basics section, retrieve product information and display the products through list rendering (map). Implement filtering and sorting according to conditions in the displayed product list.

Implement pagination 📘

Display the specified products from the rendered product list according to the conditions, and display the products on the corresponding page when a button is clicked.

Responsive Design Implementation 📘

Use media queries to adjust the number of products displayed for various devices.
