What is the proper method for correctly loading assets from a NPM package generated by webpack?

Currently, I am using webpack to create the necessary files for an npm package that will contain a selection of react components. These components include CSS that links to various fonts and icons.

However, when employing the file loader, these assets are improperly referenced with absolute paths (e.g. fonts/my-font.woff) in the main application, resulting in missing files.

Is there a solution to rectify this issue and ensure that the main app locates the correct files? I prefer to address the problem within the package itself rather than resorting to methods like manually copying the assets, as suggested by others, since I may not have complete control over the main application.

Answer №1

Including fonts in a component can be tricky, as it may conflict with the main app's style and branding. However, one way to handle this is by base64 encoding the fonts and icons and inline them in the CSS using Webpack encoder plugins.

For icons, converting them to SVG and serving them within the code is a good option. You can also base64 encode PNGs in the CSS as a fallback.

Benefits of this approach:

  • Reduces HTTP requests in the parent app
  • Ensures the parent app always has the latest icons and fonts without caching issues
  • Avoids concerns about paths and external file packaging

Cons to consider:

  • Increasing script sizes significantly
  • Losing some caching benefits
  • Potential violation of Terms of Service if you do not own the icons or fonts
