# @push.rocks/smartmarkdown
Markdown utilities for modern TypeScript projects: parse Markdown into HTML, read YAML frontmatter, and convert HTML back into clean GitHub-flavored Markdown.
`@push.rocks/smartmarkdown` wraps the Unified/Remark ecosystem for Markdown parsing and the Turndown ecosystem for HTML-to-Markdown conversion behind a small, typed API that works in Node.js and browser-oriented ESM builds.

## Install
```bash
pnpm add @push.rocks/smartmarkdown
```
## What It Does
`@push.rocks/smartmarkdown` is intentionally focused:
- Convert Markdown strings to HTML.
- Parse YAML frontmatter into a JavaScript object.
- Preserve access to the original Markdown source.
- Convert HTML strings back to Markdown using ATX headings and fenced code blocks.
- Support GitHub-flavored Markdown through `remark-gfm` and `turndown-plugin-gfm`.
## Quick Start
```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';
const html = await SmartMarkdown.easyMarkdownToHtml(`# Hello Markdown
- fast
- typed
- practical
`);
console.log(html);
// Hello Markdown
//
// - fast
// - typed
// - practical
//
```
## API
### `SmartMarkdown.easyMarkdownToHtml(markdown)`
Static convenience method for the most common path: Markdown in, HTML out.
```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';
const html = await SmartMarkdown.easyMarkdownToHtml('# Hi!');
console.log(html);
// Hi!
```
### `new SmartMarkdown().getMdParsedResultFromMarkdown(markdown)`
Parses a Markdown string into an `MdParsedResult` instance.
```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';
const smartMarkdown = new SmartMarkdown();
const result = await smartMarkdown.getMdParsedResultFromMarkdown(`---
title: Smart Docs
published: true
tags:
- markdown
- docs
---
# Smart Docs
Markdown with metadata.
`);
console.log(result.originalString); // the original Markdown input
console.log(result.html); // rendered HTML
console.log(result.frontmatterData); // { title: 'Smart Docs', published: true, tags: ['markdown', 'docs'] }
```
The returned object exposes:
- `originalString`: the Markdown input string.
- `html`: the rendered HTML output.
- `frontmatterData`: parsed YAML frontmatter as `Record`.
- `title`: currently initialized as an empty string for consumers that want to attach title metadata.
### `new SmartMarkdown().htmlToMarkdown(html)`
Converts HTML back to Markdown using Turndown with GitHub-flavored Markdown support.
```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';
const smartMarkdown = new SmartMarkdown();
const markdown = smartMarkdown.htmlToMarkdown(`
Hello
This came from HTML.
- tables, strikethrough, and task lists are handled through GFM support
`);
console.log(markdown);
// # Hello
//
// This came from HTML.
```
## Frontmatter
Frontmatter is detected with `remark-frontmatter` and parsed through `@push.rocks/smartyaml`.
```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';
const smartMarkdown = new SmartMarkdown();
const result = await smartMarkdown.getMdParsedResultFromMarkdown(`---
layout: guide
draft: false
order: 10
---
# Guide
`);
console.log(result.frontmatterData.layout); // 'guide'
console.log(result.frontmatterData.draft); // false
console.log(result.frontmatterData.order); // 10
```
If no frontmatter block is present, `frontmatterData` is an empty object.
## Markdown Features
Markdown parsing uses:
- `remark-parse` for Markdown parsing.
- `remark-gfm` for GitHub-flavored Markdown.
- `remark-frontmatter` for YAML/TOML frontmatter detection.
- `remark-html` for HTML output.
HTML-to-Markdown conversion uses:
- `turndown` with `headingStyle: 'atx'`.
- `turndown` with `codeBlockStyle: 'fenced'`.
- `turndown-plugin-gfm` for GitHub-flavored Markdown output.
## TypeScript and ESM
This package ships as an ES module and includes TypeScript declarations.
```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';
```
The package export points to the built ESM entrypoint and is ready for TypeScript, Node.js ESM, and bundler-based frontend projects.
