Modify html before sending to browser

[misty geyser]

I have a requirement to add a superscript tag for all registered marks in a page. I need to run a string replace regex on the final html generated by nextjs server. How can I achieve this?

Maybe you can use middleware, and use response.transformData?

I think you can wrap everything in a server component, by converting the children prop

What you can do is wrap something like

       <SuperscriptRegistered>
          We love BrandX® and BrandY®. The BrandZ® series is coming soon.
        </SuperscriptRegistered>

and SuperscriptRegistered

import React from 'react';

type Props = {
  children: string;
};

export default function SuperscriptRegistered({ children }: Props) {
  // Replace all occurrences of ® with superscript
  const replaced = children.replace(/®/g, '<sup>®</sup>');

  return (
    <span dangerouslySetInnerHTML={{ __html: replaced }} />
  );
}

You can wrap it around every text.

Or you can use a similar approach to wrap everything, but I'm not sure if it'll work, as it'll be too complex
