Get Started

+

Here's how to quickly install and setup MarkdownTag, no chit-chat involved.

+
+ +
+

Installation

+

Add this line of code anywhere in your HTML page:

+
+
+              
+				<script src="https://cdn.jsdelivr.net/gh/MarketingPipeline/Markdown-Tag/markdown-tag-wc.js"></script>
+              
+            
+
+

And MarkdownTag should be ready to be used.

+
+ +
+

Configuration

+

To configure MarkdownTag, edit the attributes on every md-tag you wish to configure.

+ + + + + + + + + + + + + + + + + + + + + +
AttributeMeaningDefault
flavorThe parser to render the markdown with. Can be one of showdown, github, commonmark or markedshowdown
parser_rootThe root of the remote directory where the parsers are located, if any. Refer to Parser Directory Structure for more information../
debugWhenever the debugger is enabled for this particular MarkdownTag. Refer to Debugger for more information.false
+

Editing any md-tag attribute will cause the md-tag to update the render.

+
+
+ +
+

Usage

+

On Load

+

A MarkdownTag accepts an initial input, by simply placing it on the body of the element:

+
+
+					
+						<md-tag>
+							# Hello
+						</md-tag>
+					
+				
+
+ +

Warning: The indentation of the content inside the element will not be stripped and will be interpreted by the Markdown Parsers.

+
+
+ +
+

Danger: The content inserted directly into the element will not be sanitized, due to limitations due to the DOM's functioning. To ensure safety of the input, use the API:

+
+							
+								const element = document.querySelector("md-tag") // Use your preferred method of fetching your element

+
+
+
+

Anytime

+

A MarkdownTag's content can be modified at any point, by accessing the element's API:

+
+
+					
+						const element = document.querySelector("md-tag") // Use your preferred method of fetching your element
+						element.setInput("# Hello")
+					
+				
+
+ +

Info: See API for more information. +

+
+
+ +
+

Parsers

+

Currently, MarkdownTag supports three markdown parsers.

+

Showdown - Markdown parser following the original rules as defined by John Gruber.

+

MarkdownIt - Markdown parser following the rules as defined by the Commonmark spec.

+

Marked - Fast, Lightweight Markdown parser with minimalist parsing.

+
+
+ +
+

Parser Directory Structure

+

In order for a custom parser version to be used, the following directory structure must be used:

+
+
+              
+				parsers
+				├── showdown
+				│   └── showdown.min.js
+				├── commonmark
+				│   └── markdown-it.min.js
+				└── marked
+					└── marked.min.js
+              
+            
+
+
+
+ +
+

Debugger

+

+ Each MarkdownTag element comes packed with a debugger, which logs all information about the current MarkdownTag in real time. +
+

+ +

Info: The Debugger requires a separated debug script accessible via adding this line BEFORE THE MAIN SCRIPT: +
+ <script src="https://cdn.jsdelivr.net/gh/MarketingPipeline/Markdown-Tag/markdown-tag-wc-debug.js"></script>

+
+
+ +

Warning: The Debugger will only log messages triggered since the debugger was turned on.

+
+
+ To turn on the Debugger, simply set the debug attribute on the element to "true" (See Configuration) or programically set the debugEnabled property to true. +

+
+

Methods - See API

+
+
+ +
+

API

+

+ Each MarkdownTag element can be accessed programatically via an exposed API. To access the API, simply get a handle to the element using getElementById, querySelector or your preferred method of fetching elements. +
+

+ +

Warning: Only the documented API methods were tested. Any internal calls were not tested against being called from the outside and no support will be provided if you attempt to do so.

+
+

+
+
+

Dependency Backup

+

You can use your use your own version of the supported markdown parsers, or use the predefined version, downloaded straight from the web.

+
+
+

Easy to Configure

+

Simply edit the md-tag's contents and it will automatically edit the displayed markdown!

+
+
+

Easy and simple API

+

Modifying the element is easy using our built-in API! Check out the Documentation to know more!
