Usage in a blog post page:

// app/blog/[slug]/page.js
import { getInternalLinks, applyInternalLinks } from '@/lib/internal-links';

export default async function BlogPost({ params }) {
  const [post, links] = await Promise.all([
    getPost(params.slug),
    getInternalLinks()
  ]);
  
  const contentWithLinks = applyInternalLinks(post.content, links);
  
  return (
    <article>
      <h1>{post.title}</h1>
      <div dangerouslySetInnerHTML={{ __html: contentWithLinks }} />
    </article>
  );
}

import { useState, useEffect } from 'react';

function useInternalLinks(apiKey) {
  const [links, setLinks] = useState([]);
  
  useEffect(() => {
    fetch('https://www.massblogger.com/api/internal-links?apiKey=' + apiKey)
      .then(res => res.json())
      .then(setLinks)
      .catch(console.error);
  }, [apiKey]);
  
  return links;
}

function applyInternalLinks(content, links) {
  let result = content;
  
  links.forEach(({ keyword, url }) => {
    const regex = new RegExp('\\b' + keyword + '\\b', 'gi');
    let replaced = false;
    result = result.replace(regex, (match) => {
      if (replaced) return match;
      replaced = true;
      return '<a href="' + url + '">' + match + '</a>';
    });
  });
  
  return result;
}

// Usage in component
function BlogPost({ post }) {

  );
  return response.json();
}

function applyInternalLinks(content, links) {
  let result = content;
  
  links.forEach(({ keyword, url }) => {
    // Create regex that matches whole words only
    const regex = new RegExp('\\b' + keyword + '\\b', 'gi');
    
    // Replace only first occurrence
    let replaced = false;
    result = result.replace(regex, function(match) {

      replaced = true;
      return '<a href="' + url + '">' + match + '</a>';
    });
  });

}

// Usage
document.addEventListener('DOMContentLoaded', async () => {

  const article = document.querySelector('.article-content');
  
  if (article) {
    article.innerHTML = applyInternalLinks(article.innerHTML, links);
