This is an example project reproducing an issue with source maps in htmlparser2. See:
When building for production, the source maps generated by the htmlparser2 package are being inlined in the codebase instead of being stored in separate files. This is causing the bundle size to grow significantly, which is not ideal for production environments.
To observe this behavior please run the following commands:
npm install
npm run build
npm run analyze
You will notice that the source maps occupy more that 30% of the entire bundle size.
