Build a Course Detail Page in React Native

This article guides you through building a course detail page in React Native. We’ll cover adding a back button, displaying course information like name, author, image, and description, and creating a separate component for course content. An accompanying video walks through the full process.

Learn how to create a detailed course page in your React Native application. This tutorial demonstrates how to add a back button for easy navigation, display essential course information such as the course name, author (with a fun placeholder!), and a visually appealing course image. It also covers displaying a concise course description and structuring the course content using a separate, reusable component.

Adding a Back Button

First, let’s add a back button to the course detail page for easy navigation. We’ll use the ArrowBack icon from the Expo icons library. Import the necessary component and then render it within your view. To improve the button’s appearance, apply some padding and top margin.

javascript import { ArrowBack } from ‘@expo/vector-icons’;

Displaying Course Information

Next, display the course name and author. Wrap the course name in a View and Text component, accessing the course name from the course data variable. Style the text to make it prominent with a larger font size and bold font weight. Add the author’s name below, along with styling to give it a gray color.

Adding the Course Image

Now, let’s add the course image. Import the Image component from react-native and set the source to the course image URL from the course data. Adjust the height and width styles to fit your design. Add some top margin and a border radius for a rounded look.

javascript <Image source={{ uri: course.image }} style={{ height: 200, width: ‘100%’, marginTop: 10, borderRadius: 5 }} />

Implementing the Course Description

Below the image, add a section for the course description. Start with a "About Course" heading and style it to be bold with a slightly larger font size. Then, display the course description, limiting the number of lines to keep the display concise. You can achieve this by using the numberOfLines property in the Text component. Style the description with a gray color for better readability.

javascript <Text style={{ marginTop: 10, fontWeight: ‘bold’, fontSize: 16 }}>About Course <Text numberOfLines={4} style={{ color: colors.gray }}> {course.description}

Creating a Course Content Component

For the course content section, create a separate component to keep the code organized and reusable. Create a new file called CourseContent.js and define a functional component. Import this component into the CourseDetail page and render it below the course description. Apply some top margin to the parent view of the CourseContent component.

javascript // CourseContent.js const CourseContent = () => { return ( <View style={{ marginTop: 10 }}> <Text style={{ fontWeight: ‘bold’ }}>Course Content {/ Add your course content here /} ); };

export default CourseContent;

Remember to import and render <CourseContent /> inside of your CourseDetail.js file.

Key Takeaways

• Use icons from libraries like `Expo` for common UI elements like back buttons.
• Structure your components to display dynamic data efficiently.
• Utilize styling to create a visually appealing and user-friendly interface.
• Employ separate components for reusable parts of your UI, like the course content section.
• Control text display with properties like `numberOfLines` for concise presentation.

FAQs

How do I install Expo icons?

You can install Expo icons using expo install @expo/vector-icons. Make sure you have Expo installed in your project.

How can I pass data to the CourseContent component?

You can pass data to the CourseContent component as props. For example: <CourseContent content={course.content} />. Then, access it within the component using props.content.

How do I style components in React Native?

You can use inline styles or create a StyleSheet object for more organized styling. Inline styles are applied directly to the component using the style prop. StyleSheet allows you to define styles separately and reuse them throughout your application.

By following these steps, you can create a well-structured and informative course detail page in your React Native application. Remember to focus on clear presentation, reusable components, and effective styling to provide a great user experience. This approach allows users to easily navigate and access essential course information.
