Markdown Stream Parser by NLUX 🌲✨💬

A lightweight JS/TS library that can be used to parse markdown streams as they are being read or generated.
It can be useful for LLM-powered applications that need to parse markdown streams in real-time.

This package is part of the NLUX UI toolkit for AI ecosystem.

Usage

Parsing Markdown Stream

import {
    MarkdownStreamParser,
    MarkdownStreamParserOptions,
    createMarkdownStreamParser,
} from "@nlux/markdown";

const options: MarkdownStreamParserOptions = {
    // markdownLinkTarget?: 'blank' | 'self';                       // default: 'blank'
    // syntaxHighlighter: (( Highlighter from @nlux/highlighter )), // default: undefined — for code blocks syntax highlighting
    // showCodeBlockCopyButton?: boolean,                           // default: true — for code blocks
    // skipStreamingAnimation?: boolean,                            // default: false
    // streamingAnimationSpeed?: number,                            // default: 10 ( milliseconds )
    // waitTimeBeforeStreamCompletion?: number | 'never',           // default: 2000 ( milliseconds )
    // onComplete: () => console.log("Parsing complete"),           // triggered after the end of the stream
};

const domElement = document.querySelector(".markdown-container");
const mdStreamParser: MarkdownStreamParser = createMarkdownStreamParser(
    domElement!,
    options,
);

// On each chunk of markdown
mdStreamParser.next("## Hello World");

// To call when the markdown stream is complete
// This indicates to the parser that now additional text will be added
mdStreamParser.complete();

Parsing Markdown Snapshot

import { parseMdSnapshot } from "@nlux/markdown";
const parsedMarkdown = parseMdSnapshot(snapshot, options);
