App Example

Let’s look at a practical example. Suppose you have an application where you need to process Markdown files and convert them into HTML. Here’s a simple Node.js script that uses the markdown-it library:

  const markdownIt = require('markdown-it')();
  const fs = require('fs');

  const input = fs.readFileSync('input.md', 'utf8');
  const output = markdownIt.render(input);

  fs.writeFileSync('output.html', output);

With markdown-it-cli, you can achieve the same functionality directly from the command line without writing any code:

markdown-it input.md -o output.html
