@financial-times/express-markdown-pages NPM

@financial-times/express-markdown-pages

An Express middleware that transforms plain text files into dynamic pages and fits right into your existing app.

const { MarkdownPages } = require('@financial-times/express-markdown-pages');

const markdownPages = new MarkdownPages();

app.get('/*', markdownPages.middleware, (request, response) => {
	const html = myTemplate(response.locals.markdownPages);
	response.send(html);
});

Installation

This is package for Node.js and is available through the npm registry. Node 18 or higher is required.

Installation is done using the npm install command:

npm install -S @financial-times/express-markdown-pages

Features

Fits right into your existing Express app, how you render the output is up to you!
Finds and transforms Markdown files into HTML with Origami compatible output.
Author content that works in your editor, on GitHub, and on your website.
Generates hierarchical navigation and user-friendly URLs.
Supports taxonomies to dynamically group and filter content.
Include images alongside your Markdown content, they'll work too.

Getting started

Start by creating a new instance of MarkdownPages and provide the appropriate options for your app:

const { MarkdownPages } = require('@financial-times/express-markdown-pages');

const markdownPages = new MarkdownPages({
	source: './content',
	pathPrefix: '/docs',
});

Next, add a new route to your app to serve your Markdown pages from, please note this must end with an asterisk (*) so that Express knows to route all requests to URLs beginning with this path through the MarkdownPages middleware:

app.get('/docs*');

Next, add the MarkdownPages middleware to the route you just added:

app.get('/docs*', markdownPages.middleware);

Next, add a final route handler function. This function can use the data added by the middleware to render your pages. Please note, if a page can't be found, or the incoming request is for an image file, then this function will not be called:

app.get('/docs*', markdownPages.middleware, (request, response) => {
	response.send(response.locals.markdownPages);
});

Finally, we recommend initialising MarkdownPages on app startup. This is not strictly necessary but it will help you to spot any errors with your content:

try {
	await markdownPages.init();

	app.listen(PORT, () => {
		console.log(`App listening on http://localhost:${PORT}`);
	});
} catch (error) {
	console.error('The app failed to start: ', error);
	process.exit(1);
}

Now you're up and running you can get on with using the data in your templates or carry on to the documentation for more examples.

Options

See the JSDoc type definitions for more information about configuration options.

Debugging

This package implements debug to provide detailed logs. You can enable these by setting the DEBUG environment variable:

DEBUG=express:markdownPages node app.js

Page data

The middleware provided by this package will append a markdownPages property to the response.locals object when a page matching the request is found. This object includes the content for the requested page and navigation hierarchy, and for index pages it will also include any information about taxonomies and tags used by child pages.

See the JSDoc type definitions for more information about page data.
