Installation

Integrating the MarkdownEditor Plugin into your project is straightforward. You can install it using NPM, import the JavaScript file directly, or use a CDN for rapid deployment.

Install via NPM

For projects utilizing bundling tools like Webpack, run:

npm install markdown-text-editor

---

Usage

After installation, import the MarkdownEditor class from the package:

import MarkdownEditor from "markdown-text-editor";

Basic Initialization

To get started, include a <textarea> element in your HTML and initialize the editor by targeting its container:

HTML

<textarea class="editor-container"></textarea>

JavaScript

const editor = new MarkdownEditor('.editor-container', {
    placeholder: 'Write your markdown...',
    toolbar: ['heading', 'bold', 'italic', 'strikethrough', 'ul', 'ol', 'checklist', 'blockquote', 'link', 'preview'],
});

---

CSS Setup

Using TailwindCSS

If you’re leveraging TailwindCSS, add the following configuration to your tailwind.config.js:

// tailwind.config.js
module.exports = {
  content: [
    'node_modules/markdown-text-editor/**/*.js',
    // Add your project paths here
  ],
};

Without TailwindCSS

For projects not using TailwindCSS, simply import the CSS file directly:

import 'markdown-text-editor/dist/markdown-text-editor.css';

Using a CDN

Alternatively, include the following CDN links in your HTML:

JavaScript:

<script src="https://cdn.jsdelivr.net/npm/markdown-text-editor/dist/markdown-text-editor.js"></script>

CSS:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/markdown-text-editor/dist/markdown-text-editor.css">

Markdown Content Retrieval

JavaScript Value Retrieval

In this method, you can access the markdown content entered into the editor directly using JavaScript. This is helpful when you want to dynamically retrieve the value and process it in your application (e.g., displaying it elsewhere or sending it via AJAX).

HTML

<form>
  <textarea class="editor-container h-48" rows="5"></textarea>
  <button type="button" id="submit-btn">Submit</button>
  <div class="output"></div>
</form>

JavaScript

const editor = new MarkdownEditor('.editor-container', {
    placeholder: 'Start writing...',
    toolbar: ['bold', 'italic', 'preview'],
});

document.getElementById('submit-btn').addEventListener('click', function() {
    const markdownValue = document.querySelector('.editor-container').value;
    console.log(markdownValue);
    document.querySelector('.output').innerHTML = `<pre>${markdownValue}</pre>`;
});

HTML Template Form Submission

If you prefer a traditional form submission approach (for example, in server-side applications like Django), you can integrate the markdown editor into a form that submits the value to the server for processing.

HTML (Form Submission)

<form method="POST" action="/your-server-endpoint">
    <textarea class="editor-container h-48" rows="5" name="markdown"></textarea>
    <button type="submit">Submit</button>
</form>

you can retrieve the value from a traditional <textarea> in a form submission without any custom element. When the form is submitted, the content inside the <textarea> is automatically included as part of the form data, using the name attribute of the <textarea>.

JavaScript (MarkdownEditor Initialization)

const editor = new MarkdownEditor('.editor-container', {
    placeholder: 'Write your markdown...',
    toolbar: ['preview', 'bold', 'italic'],
});

Set Markdown Content to Editor

<form method="POST" action="/your-server-endpoint">
    <textarea class="editor-container h-48" rows="5" name="markdown">Add your markdown content here</textarea>
    <button type="submit">Submit</button>
</form>

Configuration Options

Customize your Markdown editor by passing an options object during initialization. Below are some key configuration options:

Option	Type	Default	Description
placeholder	string	'Write your markdown...'	Sets the placeholder text for the textarea (optional, as you can also use the standard HTML textarea attribute)
toolbar	array	['heading', 'bold', 'italic', 'strikethrough', 'ul', 'ol', 'checklist', 'blockquote', 'link', 'preview']	Determines which tools appear in the toolbar and their order.

---

Toolbar Customization

Tailor the toolbar to suit your needs by choosing which formatting options to include. The MarkdownEditor Plugin supports several tools, including:

• bold: Enables bold text formatting.
• italic: Enables italic text formatting.
• strikethrough: Allows text to be struck through.
• ol: (Ordered List): Converts text into a numbered list format.
• ul: (Unordered List): Converts text into a bullet point list. checklist: Adds checkboxes to your text, making it great for tasks, to-do lists, or tracking completion status.
• preview: Toggles the real-time markdown preview.

Example:

const editor = new MarkdownEditor('.editor-container', {
    placeholder: 'Start writing...',
    toolbar: ['bold', 'italic', 'strikethrough', 'preview'],
});
