How to Convert Markdown to HTML using Showdown

How to Convert Markdown to HTML using Showdown

Introduction

In this tutorial, we will explore how to convert Markdown content to HTML using the Showdown library in JavaScript. Markdown is a lightweight markup language that allows you to write formatted text using an easy-to-read syntax. Showdown is a JavaScript library that enables the conversion of Markdown content to HTML.

Prerequisites

To follow along with this tutorial, you should have a basic understanding of JavaScript and have Node.js installed on your machine.

Installing Showdown

Before we can start using Showdown, we need to install it. You can install Showdown using npm (Node Package Manager) by running the following command in your terminal:

npm install showdown

Converting Markdown to HTML

Once Showdown is installed, we can begin converting Markdown content to HTML. Here’s an example of how you can do this in JavaScript:

const showdown = require('showdown');
const converter = new showdown.Converter();

const markdownContent = '# Hello, World!';
const htmlContent = converter.makeHtml(markdownContent);

console.log(htmlContent);

In the code above, we first import the showdown module and create a new instance of the Converter class. We then define our Markdown content and use the makeHtml method to convert it to HTML. Finally, we log the resulting HTML content.

Customizing Conversion Options

Showdown provides a range of options that allow you to customize the conversion process. For example, you can specify whether to interpret line breaks, whether to sanitize the resulting HTML, and more. Here’s an example that demonstrates how to specify conversion options:

const showdown = require('showdown');
const converter = new showdown.Converter({
  omitExtraWLInCodeBlocks: true,
  simplifiedAutoLink: true,
  strikethrough: true
});

const markdownContent = '~~Strikethrough text~~';
const htmlContent = converter.makeHtml(markdownContent);

console.log(htmlContent);

In this example, we pass an options object to the Converter constructor and set the omitExtraWLInCodeBlocks, simplifiedAutoLink, and strikethrough options. We then convert the Markdown content and log the resulting HTML.

Conclusion

Converting Markdown to HTML using the Showdown library in JavaScript is a powerful tool for rendering formatted content on the web. It allows you to write your content in an easy-to-read plain text format while still achieving a professional-looking presentation.

Remember to refer to the Showdown documentation for more information on the library and its capabilities.
