# @push.rocks/smartmarkdown
do more with markdown files

## Install
To install `@push.rocks/smartmarkdown`, you can use npm or yarn. Run one of the following commands in your terminal:

```bash
npm install @push.rocks/smartmarkdown --save
```

or if you use yarn:

```bash
yarn add @push.rocks/smartmarkdown
```

This module is designed to be used in a Node.js environment or in a frontend project that supports ES Modules.

## Usage
`@push.rocks/smartmarkdown` offers powerful tools to work with markdown files, including parsing markdown to HTML, extracting frontmatter data, and converting HTML back to markdown. Below, we'll explore how to utilize these features effectively.

### **Parsing Markdown to HTML**

Let's start by converting a simple Markdown string to HTML:

```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';

async function parseMarkdown() {
  const mdString = `# Hello World
  
This is a simple markdown string.`;
  const htmlString = await SmartMarkdown.easyMarkdownToHtml(mdString);
  console.log(htmlString); // Logs the HTML string
}

parseMarkdown();
```

In this example, `SmartMarkdown.easyMarkdownToHtml` is a convenient static method that takes a markdown string and returns its HTML representation.

### **Working with Frontmatter**

Markdown files often contain frontmatter, which is metadata specified at the top of the file. `@push.rocks/smartmarkdown` can extract this data along with converting the content.

```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';

async function parseMarkdownWithFrontmatter() {
  const markdownWithFrontmatter = `---
title: "My First Post"
date: 2023-01-01
tags: ["blog", "post"]
---
  
# Hello World
  
This is a post with frontmatter.`;
  
  const smartmarkdownInstance = new SmartMarkdown();
  const mdParsedResult = await smartmarkdownInstance.getMdParsedResultFromMarkdown(markdownWithFrontmatter);
  console.log(mdParsedResult.frontmatterData); // Logs: { title: "My First Post", date: "2023-01-01", tags: ["blog", "post"] }
  console.log(mdParsedResult.html); // Logs: HTML content
}

parseMarkdownWithFrontmatter();
```

In the code above, we manually create an instance of `SmartMarkdown` to access the `getMdParsedResultFromMarkdown` method, which returns an object containing both the HTML and the frontmatter data.

### **HTML to Markdown Conversion**

Sometimes, you may need to convert HTML back to Markdown. Here's how you can do it:

```typescript
import { SmartMarkdown } from '@push.rocks/smartmarkdown';

const smartmarkdownInstance = new SmartMarkdown();
const htmlString = '<h1>Hello World</h1><p>This is a simple HTML string.</p>';
const markdownString = smartmarkdownInstance.htmlToMarkdown(htmlString);
console.log(markdownString);
```

In this example, we use the `htmlToMarkdown` method to convert an HTML string back to Markdown. This is particularly useful when working with content editing interfaces that support both formats.

### **Advanced Usage: Parsing Markdown with Custom Plugins**

`@push.rocks/smartmarkdown` leverages Unified, Remark, and Turndown to provide its functionality. You can extend its capabilities by using custom plugins.

For instance, if you wanted to use a custom Remark plugin to highlight code blocks, you would:

1. Create a new SmartMarkdown instance.
2. Configure it to use your custom plugins.
3. Process your markdown content.

```typescript
// This is a hypothetical example. Please refer to the respective plugin documentation for actual implementation details.

import { SmartMarkdown } from '@push.rocks/smartmarkdown';
import myRemarkPlugin from 'remark-myplugin';

async function parseMarkdownWithPlugin(mdString: string) {
  const smartMarkdownInstance = new SmartMarkdown();
  smartMarkdownInstance.useRemarkPlugin(myRemarkPlugin, pluginOptions);
  const result = await smartMarkdownInstance.getMdParsedResultFromMarkdown(mdString);
  // Now `result` will include transformations done by your custom plugin.
}
```

`@push.rocks/smartmarkdown` provides a solid base for performing various markdown related tasks in your projects. Whether parsing, transforming, or exporting content, its utilities and integrations offer flexibility for most needs. By leveraging ES Modules and TypeScript, it ensures type safety and enhances developer experience with excellent IntelliSense support.
