Design Principles

Zero dependencies — Pure Node.js, works with v0.12+ (no npm install needed)
CMS-friendly — Output is clean HTML suitable for direct database insertion
No wrapper HTML — Outputs content HTML only (no <html>, <head>, <body>)
Safe escaping — Code blocks escape < and > to prevent XSS

Typical Use Cases

AI Content Pipeline — LLM generates Markdown → convert to HTML → publish to CMS
Static site generation — Batch convert .md files to .html
Documentation — Convert README.md to HTML for web display

Pipeline Integration Example

For automated AI content pipelines that generate Markdown but publish HTML:

var converter = require('./scripts/md2html.js');
var rawMarkdown = llmResponse.choices[0].message.content;
var htmlContent = converter.markdownToHtml(rawMarkdown);
// Now publish htmlContent to your CMS API
