How to Properly Render Images in React with webpack

When working with a React application, one common issue that developers face is rendering images. Especially when you're using webpack for your module bundling, you might encounter errors such as “failed to load resource..404 not found”. This post will guide you through how to solve this issue and properly structure your images in React.

The Problem

You’re trying to render images using a relative path in your React app, but the image fails to load. In the example provided, you have this code in your App.js:

While the imported image displays correctly, the image with a relative path does not. Let's break down how to fix this issue.

Understanding Your Project Structure

Before diving into solutions, it’s crucial to understand your project structure:

As you can see, the images are located within the src/images directory. This is an important detail that affects how webpack manages your resources.

Solution: Moving Images to the Public Folder

Why It’s Necessary

When you want to use relative paths for assets like images in your React application, they need to be accessible from a public URL. This means they should be located in the public folder of your project. By default, webpack only processes files found within the src directory during the build.

Steps to Fix the Issue

Create a Public Folder:

Create a directory at the root of your project named public.

Move Your Images:

Move your images folder into the public directory. The structure should look like this:

Update Your Image Tag:

Now that the test.jpg image is within the public/images folder, update your img tag in App.js to reference the new path:

Conclusion

Using the public folder for static assets like images allows you to take advantage of relative paths in React applications managed by webpack. This method not only solves the 404 errors but keeps your application organized.

By following the above steps, you should be able to render images in your React application smoothly, regardless of their path. If you run into any other issues with webpack or React, don't hesitate to reach out for further assistance.

With these changes, you can focus more on building your application rather than worrying about missing image resources. Happy coding!
