ℹ️ Markdown Preview runs entirely client-side using regex-based rendering. No server API is needed. Here's how to use a similar approach in your own code:
Simple Markdown to HTML conversion in JavaScript.
// Client-side Markdown rendering — no API call neededfunctionrenderMarkdown(md) {
return md
.replace(/^### (.+)$/gm, '<h3>$1</h3>')
.replace(/^## (.+)$/gm, '<h2>$1</h2>')
.replace(/^# (.+)$/gm, '<h1>$1</h1>')
.replace(/\*\*(.+?)\*\*/g, '<strong>$1</strong>')
.replace(/\*(.+?)\*/g, '<em>$1</em>')
.replace(/`([^`]+)`/g, '<code>$1</code>')
.replace(/\n\n/g, '</p><p>');
}
const html = renderMarkdown("# Hello\n\n**Bold** and *italic*");
// → "<h1>Hello</h1></p><p><strong>Bold</strong> and <em>italic</em>"
