How to point to an Image source after compiler changes the file name?

When working with TypeScript, it is common for the compiler to change the file names of your assets, including images. This can lead to broken image links if you are referencing the image by its original file name. In this blog post, we will explore a few solutions to this problem.

Solution 1: Using a relative path

One way to ensure that your image source points to the correct file even after the compiler changes its name is by using a relative path. By referencing the image using a relative path, you can ensure that the correct file is always loaded, regardless of its name.

Here’s an example of how you can use a relative path to reference an image:

Make sure to adjust the path according to your project structure and the location of the image file.

Solution 2: Using a build tool

Another solution to this problem is to use a build tool, such as Webpack or Gulp, that can handle the renaming of file names during the build process. These build tools allow you to define rules and configurations to handle file renaming and ensure that your image references are updated accordingly.

Here’s an example of how you can configure Webpack to handle file renaming:

module.exports = {
  // ... other Webpack configurations
  module: {
    rules: [
      {
        test: /.(png|jpe?g|gif)$/i,
        use: [
          {
            loader: 'file-loader',
            options: {
              name: '[name].[ext]',
              outputPath: 'assets/images/',
              publicPath: 'assets/images/'
            }
          }
        ]
      }
    ]
  }
}

This configuration tells Webpack to rename any image files with the same name and extension and output them to the specified output path. The publicPath option ensures that the image references in your code are updated accordingly.

Remember to adjust the configuration according to your project’s needs and file structure.

Solution 3: Using a dynamic import

If you prefer a more dynamic approach, you can use a dynamic import to load the image at runtime. This allows you to programmatically determine the correct file name and path based on the compiler’s changes.

Here’s an example of how you can use a dynamic import to load an image:

const image = import('./assets/image.jpg').then(module => {
  const img = document.createElement('img');
  img.src = module.default;
  document.body.appendChild(img);
});

This code dynamically imports the image file and sets the src attribute of the img element to the resolved module’s default export, which is the file path.

Choose the solution that best fits your project’s needs and structure. By implementing one of these solutions, you can ensure that your image sources are correctly referenced even after the compiler changes the file names.
