GitHub - chuanqisun/semidown: Semi-incremental markdown parser and renderer, optimized for LLM output.

A semi-incremental streaming markdown parser and renderer for the web, designed for handling LLM streaming out.

Below is a simplified usage example. See src/main.ts for a full-featured demo with UI controls.

import { Semidown } from "semidown";

const outputContainer = document.getElementById("output");
const parser = new Semidown(outputContainer);

// Simulate streaming input
const markdown = "# Hello\nThis is a **streaming** demo.";
let idx = 0;
const interval = setInterval(() => {
  if (idx < markdown.length) {
    parser.write(markdown[idx++]);
  } else {
    parser.end();
    clearInterval(interval);
  }
}, 50);
