  [Button Text](button:https://example.com)

Installation

npm install @uniwebcms/content-reader

Usage

Basic usage:

const { markdownToProseMirror } = require("@uniwebcms/content-reader");

const markdown = `
# Hello World

This is a **bold** statement with a [link](https://example.com).

- List item 1
- List item 2
  - Nested item
`;

const doc = markdownToProseMirror(markdown);

Using with TipTap

The library is designed to work seamlessly with TipTap editors:

import { Editor } from "@tiptap/core";
import { markdownToProseMirror } from "@uniwebcms/content-reader";

const editor = new Editor({
  content: markdownToProseMirror(markdown),
  // ... other TipTap configuration
});

Advanced Features

Working with Image Roles

The library supports extended image syntax for different display contexts:

const markdown = `
![Header image](background:header.jpg)
![Profile photo](gallery:profile.jpg)
![Settings](icon:settings.svg)
`;

const doc = markdownToProseMirror(markdown);
// Each image will have a 'role' attribute in its output structure

Handling Tables with Alignment

Tables support column alignment and formatted content:

const markdown = `
| Name | Status | Actions |
|:-----|:------:|--------:|
| John | Active | **Edit** |
| Jane | Away   | *View*   |
`;

const doc = markdownToProseMirror(markdown);
// Table cells will have appropriate alignment attributes

Architecture

The library is organized into several modules:

• Parser Core: Handles the main parsing logic and orchestration
• Block Parser: Processes block-level elements
• Inline Parser: Handles inline formatting and text
• Extensions: Manages extended syntax features
• Schema: Defines the document structure
