How to Handle Image Paths Correctly in React.js Projects?

Correct Approach for Image Paths in React.js

Determining the correct path for images in React.js projects has been a common challenge. Traditionally, relative paths were used within the src attribute, based on the project's file structure. However, in React.js projects built with create-react-app, this approach may not always work.

This is evident from the example provided, where images are displayed correctly when the route is "/details/2" but not when it is "/details/2/id." This inconsistency arises because the relative path is being interpreted based on the URL structure rather than the file architecture.

To resolve this issue, an alternative method is recommended for defining image paths in React.js projects. Instead of using relative paths in the src attribute, images can be imported using the import statement. For example:

import logo from './logo.png';

class Nav extends Component {
  render() {
    return (<img src={logo} alt="logo" />);
  }
}

In this approach, the import statement specifies the relative path to the image file, and the image is then stored as a variable. When rendering the component, this variable is used as the source for the image.

This method ensures that the image path remains consistent across different routes handled by React-router, as the relative path is established during the import process and not based on the current URL structure. As a result, all images will be displayed correctly regardless of the specific route being accessed.
