Accessing Image Files Outside the Public Folder in React

When building a shopping website using React alongside an ASP.Net Core backend, you may encounter challenges when trying to access image files stored outside the public folder. This is a common issue for developers, particularly those who are new to React. In this guide, we will address the problem and provide a detailed solution that you can implement quickly and efficiently.

The Problem: Accessing Images Outside the Public Folder

You might find yourself attempting to directly reference an image file stored in a directory on your server. For instance, you may try to set a path like this in your React component:

Then, you may attempt to render an image like this:

However, if you try accessing images this way, it likely won't work due to the restrictions on file paths that React imposes when it comes to the public folder. React applications are built to serve static files from the public directory, which leads many developers to look for workarounds.

The Solution: Utilizing a Server URL for Your Images

To address this issue and effectively load your images, a simple yet powerful solution is to serve your image files through a URL rather than a local path. Here’s how to do it step by step:

Step 1: Serve Images via Your Backend

You need to ensure that your ASP.Net Core backend is configured to serve static files from the directory where your product images are stored. You can set this up in your ASP.Net Core application by adding the following configuration in the Startup.cs file:

Step 2: Modify Your API to Serve Images

Adjust your ASP.Net API to expose a route for accessing the images, for example:

Step 3: Update React Component to Use Server URL

With your backend configured to serve the images, you can now update your React component to reference the images via a URL. Here’s how you can do it in your component:

Finally, use this URL in your image component:

Why This Solution Works

By using a server URL instead of a file path, you ensure that your React application correctly accesses the product images served by the backend. This allows you to keep your images organized and makes it easy to manage them through your server.

Conclusion

In conclusion, accessing image files from outside the public folder in a React application can be accomplished easily by serving them through your ASP.Net Core backend. Rather than trying to directly link to local file paths, utilize a structured server URL to fetch your images dynamically. This method not only resolves access issues but also enhances the structure and maintainability of your application.

With this knowledge, you're now equipped to manage images in your React applications more effectively. Happy coding!
