ts-markdown-parser
ts-markdown-parser is a TypeScript-based library for converting Markdown to HTML with built-in syntax highlighting for various programming languages. Currently, it supports HTML, JavaScript, TypeScript, SQL, Python, and others for code highlighting, with plans to expand to more languages in the future.
Installation
To install the package, run:
npm install ts-markdown-parserUsage
Here's a basic example of how to use ts-markdown-parser to convert Markdown to HTML:
const { markdownToHtml } = require("ts-markdown-parser");
// Your Markdown content
const markdown = `
# Sample Heading
\`\`\`javascript
console.log("Hello, world!");
\`\`\`
## Subheading
Some text.
[Link text](https://example.com)

// Convert Markdown to HTML
const htmlContent = markdownToHtml(markdown);
// Basic HTML template
const htmlTemplate = `
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

// Output HTML to a file or use as neededTypeScript Usage
Here's how you might use it in your TypeScript code:
import * as fs from "fs";
import { markdownToHtml, getMarkdownMetadata } from "ts-markdown-parser";
// ...
const file = "/path/to/my-markdown.md";
const markdownString = fs.readFileSync(file, "utf8");
const htmlString: string | undefined = markdownToHtml(markdownString);
if (!htmlString) {
console.error(`Failed to generate HTML from: ${file}.`);
}
const metadata: Record<string, any> = getMarkdownMetadata(markdownString);
if (!metadata?.title) {
console.error(`Markdown file '${file}' is missing metadata.`);
}npx Command to Test Code
Use npx ts-node to test a TypeScript usage of this package:
npx ts-node test.tsYou can also use ts-node like so:
ts-node test.tsMetadata Parsing
You can also extract metadata from your Markdown files using YAML front matter.
Here's how to use the getMarkdownMetadata() function:
const { getMarkdownMetadata } = require("ts-markdown-parser");
// Your Markdown content with YAML front matter
const markdown = `
---
title: "Example Markdown Article for HTML"
author: "ChatGPT"
date: 2024-08-19
keywords: scripting, html, web development, markdown, blog
slug: markdown-article-test-for-html
---
# Sample Heading
Some text.
`;
// Extract metadata
const metadata = getMarkdownMetadata(markdown);
console.log(metadata);The metadata object literal response should look something like this:
{
title: 'Example Markdown Article for HTML',
author: 'ChatGPT',
date: '2024-08-19', // Date formatted as string
keywords: [ 'scripting', 'html', 'web development', 'markdown', 'blog' ],
slug: 'markdown-article-test-for-html'
}Example YAML Front Matter
YAML front matter is a way to include metadata at the top of your Markdown files. Here's another example:
---
title: "Example Markdown Article for HTML"
author: "ChatGPT"
date: 2024-08-19
id: "1234"
keywords: scripting, html, web development, markdown, blog
slug: markdown-article-test-for-html
---Metadata Extraction Result
Given the YAML front matter above, getMarkdownMetadata would return:
{
"title": "Example Markdown Article for HTML",
"author": "ChatGPT",
"date": "2024-08-19", // Date formatted as string
"id": 1234, // String representation of number parsed and casted as number
"keywords": ["scripting", "html", "web development", "markdown", "blog"],
"slug": "markdown-article-test-for-html"
