Markdown is a lightweight text markup language that allows the marked text to be converted to various formats. The original goal of creating Markdown was of enabling people “to write using an easy-to-read and easy-to-write plain text format” and to optionally convert it to structurally valid XHTML (or HTML). Currently, with WordPress supporting Markdown, the format has become even more widely used.

The purpose of writing the article is to show you how to use Node.js and the Express framework to create an API endpoint. The context in which we will be learning this is by building an application that converts Markdown syntax to HTML. We will also be adding an authentication mechanism to the API so as to prevent misuse of our application.

A Markdown Node.js Application

Our teeny-tiny application, which we will call ‘Markdown Convertor’, will enable us to post Markdown-styled text and retrieve an HTML version. The application will be created using the Node.js Express framework, and support authentication for conversion requests.

We will build the application in small stages — initially creating a scaffold using Express and then adding various features like authentication as we go along. So let us start with the initial stage of building the application by creating a scaffold.

Stage 1: Installing Express

Assuming you’ve already installed Node.js on your system, create a directory to hold your application (let’s call it “markdown-api”), and switch to that directory:

$ mkdir markdown-api
$ cd markdown-api

Use the npm init command to create a package.json file for your application. This command prompts you for a number of things like the name and version of your application.

For now, simply hit Enter to accept the defaults for most of them. I’ve used the default entry point file as index.js, but you could try app.js or some other depending on your preferences.

Now install Express in the markdown-api directory and save it in the dependencies list:

$ npm install express –save

Create an index.js file in the current directory (markdown-api) and add the following code to test if the Express framework is properly installed:

Const express = require(‘express’);
var app = express();

app.get(‘/’, function(req, res){
res.send(‘Hello World!’);
});

app.listen(3000);

Now browse to the URL http://localhost:3000 to check whether the test file is working properly. If everything is in order, we will see a Hello World!’ greeting in the browser and we can proceed to build a base API to convert Markdown to HTML.

Stage 2: Building A Base API

The primary purpose of our API will be to convert text in a Markdown syntax to HTML. The API will have two endpoints:

/login
/convert

The login endpoint will allow the application to authenticate valid requests while the convert endpoint will convert (obviously) Markdown to HTML.

Below is the base API code to call the two endpoints. The login call just returns an “Authenticated” string, while the convert call returns whatever Markdown content you submitted to the application. The home method just returns a ‘Hello World!’ string.

const express = require(“express”);
const bodyParser = require(‘body-parser’);

var app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

app.get(‘/’, function(req, res){
res.send(‘Hello World!’);
});

app.post(‘/login’, function(req, res) {
res.send(“Authenticated”);
},
);

app.post(“/convert”, function(req, res, next) {
console.log(req.body);
if(typeof req.body.content == ‘undefined’ || req.body.content == null) {
res.json([“error”, “No data found”]);
} else {
res.json([“markdown”, req.body.content]);
}
});

app.listen(3000, function() {
console.log(“Server running on port 3000”);
});

We use the body-parser middleware to make it easy to parse incoming requests to the applications. The middleware will make all the incoming requests available to you under the req.body property. You can do without the additional middleware but adding it makes it far easier to parse various incoming request parameters.

You can install body-parser by simply using npm:

$ npm install body-parser

Now that we have our dummy stub functions in place, we will use Postman to test the same. Let’s first begin with a brief overview of Postman.

Postman Overview

Postman is an API development tool that makes it easy to build, modify and test API endpoints from within a browser or by downloading a desktop application (browser version is now deprecated). It has the ability to make various types of HTTP requests, i.e. GET, POST, PUT, PATCH. It is available for Windows, macOS, and Linux.

Here’s a taste of Postman’s interface:

(Large preview)

To query an API endpoint, you’ll need to do the following steps:

Enter the URL that you want to query in the URL bar in the top section;
Select the HTTP method on the left of the URL bar to send the request;
Click on the ‘Send’ button.

Postman will then send the request to the application, retrieve any responses and display it in the lower window. This is the basic mechanism on how to use the Postman tool. In our application, we will also have to add other parameters to the request, which will be described in the following sections.

Using Postman

Now that we have seen an overview of Postman, let’s move forward on using it for our application.

Start your markdown-api application from the command-line:

$ node index.js

To test the base API code, we make API calls to the application from Postman. Note that we use the POST method to pass the text to convert to the application.

The application at present accepts the Markdown content to convert via the content POST parameter. This we pass as a URL encoded format. The application, currently, returns the string verbatim in a JSON format — with the first field always returning the string markdown and the second field returning the converted text. Later, when we add the Markdown processing code, it will return the converted text.

Stage 3: Adding Markdown Convertor

With the application scaffold now built, we can look into the Showdown JavaScript library which we will use to convert Markdown to HTML. Showdown is a bidirectional Markdown to HTML converter written in Javascript which allows you to convert Markdown to HTML and back.

(Large preview)

Install the package using npm:

$ npm install showdown

After adding the required showdown code to the scaffold, we get the following result:

const express = require(“express”);
const bodyParser = require(‘body-parser’);
const showdown = require(‘showdown’);

var app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

converter = new showdown.Converter();

app.get(‘/’, function(req, res){
res.send(‘Hello World!’);
});

app.post(‘/login’, function(req, res) {
res.send(“Authenticated”);
},
);

app.post(“/convert”, function(req, res, next) {
if(typeof req.body.content == ‘undefined’ || req.body.content == null) {
res.json([“error”, “No data found”]);
} else {
text = req.body.content;
html = converter.makeHtml(text);
res.json([“markdown”, html]);
}
});

app.listen(3000, function() {
console.log(“Server running on port 3000”);
});

The main converter code is in the /convert endpoint as extracted and shown below. This will convert whatever Markdown text you post to an HTML version and return it as a JSON document.

…
} else {
text = req.body.content;
html = converter.makeHtml(text);
res.json([“markdown”, html]);
}

The method that does the conversion is converter.makeHtml(text). We can set various options for the Markdown conversion using the setOption method with the following format:

converter.setOption(‘optionKey’, ‘value’);

So, for example, we can set an option to automatically insert and link a specified URL without any markup.

converter.setOption(‘simplifiedAutoLink’, ‘true’);

As in the Postman example, if we pass a simple string (such as Google home http://www.google.com/) to the application, it will return the following string if simplifiedAutoLink is enabled:

<p>Google home <a href=”http://www.google.com/”>http://www.google.com/</a></p>

Without the option, we will have to add markup information to achieve the same results:

Google home <http://www.google.com/>

There are many options to modify how the Markdown is processed. A complete list can be found on the Passport.js website.

So now we have a working Markdown-to-HTML converter with a single endpoint. Let us move further and add authentication to have application.

Stage 4: Adding API Authentication Using Passport

Exposing your application API to the outside world without proper authentication will encourage users to query your API endpoint with no restrictions. This will invite unscrupulous elements to misuse your API and also will burden your server with unmoderated requests. To mitigate this, we have to add a proper authentication mechanism.

We will be using the Passport package to add authentication to our application. Just like the body-parser middleware we encountered earlier, Passport is an authentication middleware for Node.js. The reason we will be using Passport is that it has a variety of authentication mechanisms to work with (username and password, Facebook, Twitter, and so on) which gives the user the flexibility on choosing a particular mechanism. A Passport middleware can be easily dropped into any Express application without changing much code.

Install the package using npm.

$ npm install passport

We will also be using the local strategy, which will be explained later, for authentication. So install it, too.

$ npm install passport-local

You will also need to add the JWT(JSON Web Token) encode and decode module for Node.js which is used by Passport:

$ npm install jwt-simple

Strategies In Passport

Passport uses the concept of strategies to authenticate requests. Strategies are various methods that let you authenticate requests and can range from the simple case as verifying username and password credentials, authentication using OAuth (Facebook or Twitter), or using OpenID. Before authenticating requests, the strategy used by an application must be configured.

In our application, we will use a simple username and password authentication scheme, as it is simple to understand and code. Currently, Passport supports more than 300 strategies which can be found here.

Although the design of Passport may seem complicated, the implementation in code is very simple. Here is an example that shows how our /convert endpoint is decorated for authentication. As you will see, adding authentication to a method is simple enough.

app.post(“/convert”,
passport.authenticate(‘local’,{ session: false, failWithError: true }),
function(req, res, next) {
// If this function gets called, authentication was successful.
// Also check if no content is sent
if(typeof req.body.content == ‘undefined’ || req.body.content == null) {
res.json([“error”, “No data found”]);
} else {
text = req.body.content;
html = converter.makeHtml(text);
res.json([“markdown”, html]);
}},
// Return a ‘Unauthorized’ message back if authentication failed.
function(err, req, res, next) {
return res.status(401).send({ success: false, message: err })
});

Now, along with the Markdown string to be converted, we also have to send a username and password. This will be checked with our application username and password and verified. As we are using a local strategy for authentication, the credentials are stored in the code itself.

Although this may sound like a security nightmare, for demo applications this is good enough. This also makes it easier to understand the authentication process in our example. Incidentally, a common security method used is to store credentials in environment variables. Still, many people may not agree with this method, but I find this relatively secure.

The complete example with authentication is shown below.

const express = require(“express”);
const showdown = require(‘showdown’);
const bodyParser = require(‘body-parser’);
const passport = require(‘passport’);
const jwt = require(‘jwt-simple’);
const LocalStrategy = require(‘passport-local’).Strategy;

var app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

converter = new showdown.Converter();

const ADMIN = ‘admin’;
const ADMIN_PASSWORD = ‘smagazine’;
const SECRET = ‘secret#4456’;

passport.use(new LocalStrategy(function(username, password, done) {
if (username === ADMIN && password === ADMIN_PASSWORD) {
done(null, jwt.encode({ username }, SECRET));
return;
}
done(null, false);
}));

app.get(‘/’, function(req, res){
res.send(‘Hello World!’);
});

app.post(‘/login’, passport.authenticate(‘local’,{ session: false }),
function(req, res) {
// If this function gets called, authentication was successful.
// Send a ‘Authenticated’ string back.
res.send(“Authenticated”);
});

app.post(“/convert”,
passport.authenticate(‘local’,{ session: false, failWithError: true }),
function(req, res, next) {
// If this function gets called, authentication was successful.
// Also check if no content is sent
if(typeof req.body.content == ‘undefined’ || req.body.content == null) {
res.json([“error”, “No data found”]);
} else {
text = req.body.content;
html = converter.makeHtml(text);
res.json([“markdown”, html]);
}},
// Return a ‘Unauthorized’ message back if authentication failed.
function(err, req, res, next) {
return res.status(401).send({ success: false, message: err })
});

app.listen(3000, function() {
console.log(“Server running on port 3000”);
});

A Postman session that shows conversion with authentication added is shown below.

Final application testing with Postman (Large preview)

Here we can see that we have got a proper HTML converted string from a Markdown syntax. Although we have only requested to convert a single line of Markdown, the API can convert a larger amount of text.

This concludes our brief foray into building an API endpoint using Node.js and Express. API building is a complex topic and there are finer nuances that you should be aware of while building one, which sadly we have no time for here but will perhaps cover in future articles.

Accessing Our API From Another Application

Now that we have built an API, we can create a small Node.js script that will show you how the API can be accessed. For our example, we will need to install the request npm package that provides a simple way to make HTTP requests. (You will Most probably already have this installed.)

$ npm install request –save

The example code to send a request to our API and get the response is given below. As you can see, the request package simplifies the matter considerably. The markdown to be converted is in the textToConvert variable.

Before running the following script, make sure that the API application we created earlier is already running. Run the following script in another command window.

Note: We are using the (back-tick) sign to span multiple JavaScript lines for the textToConvert variable. This is not a single-quote.

var Request = require(“request”);

// Start of markdown
var textToConvert = `Heading
=======
## Sub-heading

Paragraphs are separated
by a blank line.

Two spaces at the end of a line
produces a line break.

Text attributes _italic_,
**bold**, ‘monospace’.
A [link](http://example.com).
Horizontal rule:`;

// End of markdown

Request.post({
“headers”: { “content-type”: “application/json” },
“url”: “http://localhost:3000/convert”,
“body”: JSON.stringify({
“content”: textToConvert,
“username”: “admin”,
“password”: “smagazine”
})
}, function(error, response, body){
// If we got any connection error, bail out.
if(error) {
return console.log(error);
}
// Else display the converted text
console.dir(JSON.parse(body));
});

When we make a POST request to our API, we provide the Markdown text to be converted along with the credentials. If we provide the wrong credentials, we will be greeted with an error message.

{
success: false,
message: {
name: ‘AuthenticationError’,
message: ‘Unauthorized’,
status: 401
}
}

For a correctly authorized request, the above sample Markdown will be converted to the following:

[ ‘markdown’,
`<h1 id=”heading”>Heading</h1>
<h2 id=”subheading”>Sub-heading</h2>
<p>Paragraphs are separated by a blank line.</p>
<p>Two spaces at the end of a line<br />
produces a line break.</p>
<p>Text attributes <em>italic</em>,
<strong>bold</strong>, ‘monospace’.
A <a href=”http://example.com”>link</a>.
Horizontal rule:</p>` ]

Although we have hardcoded the Markdown here, the text can come from various other sources — file, web forms, and so on. The request process remains the same.

Note that as we are sending the request as an application/json content type; we need to encode the body using json, hence the JSON.stringify function call. As you can see, it takes a very small example to test or API application.

Conclusion

In this article, we embarked on a tutorial with the goal of learning on how to use Node,js and the Express framework to build an API endpoint. Rather than building some dummy application with no purpose, we decided to create an API that converts Markdown syntax to HTML, which anchors or learning in a useful context. Along the way, we added authentication to our API endpoint, and we also saw ways to test our application endpoint using Postman.

Welcome to our roundup of the best new sites to be launched (or relaunched with significant updates) in the last four weeks.

After last month’s flirtation with monochrome, this month’s set of sites return to the overriding trend of 2019: color. Huge images are still popular, and parallax is still finding its way into our scrolling experiences. Enjoy!

Middle Fork Rapid Transit

Middle Fork Rapid Transit is an adventure vacation company that transports you over 100 miles down the Middle Fork river in Idaho. Its site packs in as much as one of its trips, and there’s tons of little details to get you fired up; I love the animated raft, and the grub looks amazing.

To Taste

To Taste is my favorite recipe site of the moment. Packed with food ideas for every occasion and palette, the simple site is laid out perfectly for browsing, and choosing something to make is a culinary treat. What really makes it, as with all food sites, is the mouth-watering photography.

The Face

Style bible The Face returned from oblivion this month, with a new team behind the iconic publication. Its site opens as daringly as you’d expect, before slowing to a more traditional, and more usable blog format.

Kia ProCeed

The site for the new Kia ProCeed is precisely the type of site we used to build back in the day. With interactive video, a unique navigation system based on established design patterns, and carefully designed usability, it’s an enticing experience.

Hiraeth

Co-founded by Rooney Mara, Hiraeth is a fashion label that produces desirable clothes free from any animal product. Its elegant site exudes quality with generous white space, and an almost Scandinavian minimalism, matching the garments perfectly.

Future of Sustainability

According to some estimates, we have just 12 years until we face not just climate change, but climate breakdown. Future of Sustainability wants to inspire you to change the 2020s, before it’s too late. It communicates a complex, and difficult message engagingly.

Nicholas Jackson

Nicholas Jackson is a New York based designer and art director. His portfolio site is a bold, confident expression of the work he loves to do for clients including Canon, The Wall Street Journal, The NY times, and Siemens.

Mansi

Mansi makes some of the best pasta this side of Naples, and it has an equally delicious website. Dotted throughout the site are pasta shapes, some of them animated, making Mansi’s site the most appropriate exponent of the blob trend I’ve seen to date.

Azab

Azab is an architecture firm with a love of mouse trails. Despite most designers abandoning them more than a decade ago, Azab’s site is built entirely around the path of your mouse on the screen. It’s surprisingly compelling.

Corpus

Corpus is an all-natural, all-vegan company producing deodorants that don’t harm you, or the planet. Its site intriguingly turns a standard e-commerce layout on its head, by presenting products up front, and the traditional hero video, down below.

Calidad Beer

Calidad Beer is a Mexican-style beer, brewed in California. With Levis-worthy art direction, and brand appropriate animation, its site is ideal for an unknown company trying to tap into a saturated market. Constantly reinforced, the brand identity is key here.

DEMO

The Design in Motion Festival, or DEMO for short, takes place in Amsterdam in November, when 80 screens in the central train station will showcase the best motion design work. The site itself features beautiful interactive lettering that Saul Bass would be proud of.

Camille Pawlak

The online portfolio of Camille Pawlak is based around a beautiful central animation that rotates as it transforms into the next project. It’s a simple, but elegant way to navigate between projects, and the work that she’s showcasing is excellent too.

Green Chameleon

Green Chameleon’s site is only temporary, with a full website redesign on the horizon. But with a portfolio like this, packed with parallax effects, and dead simple navigation, I think the Bristol agency should stick with what it’s got.

Flwr

Flwr is a New Zealand based florist with a modern approach. Its site uses text to mask its beautiful photography, creating an intriguing and inviting mini-site. It even embraces the split-screen trend to great effect.

Daly

Daly is a PR agency founded by Alex Daly, from her contacts built helping some of the world’s most successful crowdfund campaigns reach their targets. Its site is bold, colorful, and fun. The period after its name isn’t new, but I love the way it follows you down the page as you scroll.

Pacto Navio

When the finest Cuban rum is introduced to French wine making traditions, you get Pacto Navio. The rum, distilled near Havana, is served by a beautifully art directed site, featuring brand illustrations, and a distinctly Caribbean feeling.

Cheval Blanc

The French have a reputation for refined hospitality, and that trend is reflected in their love of sophisticated web sites. The site for Cheval Blanc is no exception, with a just-right level of parallax scrolling and refined typography.

Staat

Staat is a design agency specializing in event design for some of the world’s best known names. Its site features video case studies of its work, and the site itself takes a step backwards and allows the portfolio to shine.

Festa da Francofonia 2019

The 2019 festival for Francophones, is a festival celebrating the 220 million people worldwide who speak the French language. Celebrated from Morocco to Canada, the event’s site is a colorful, international feeling affair, appropriate for a multi-cultural event.

Today we’d like to explore a specific reveal effect with you. If you saw the Crossroads Slideshow a while back, you might have noticed the page transition when the content is shown after an image gets clicked. We call this type of transitions a “reveal” animation because some content is already there while an overlay element animates out, revealing what’s underneath.

To make such an effect is pretty straightforward: simply place an overlay with the same or different color of the page background and animate it out of the viewport; whatever is under it will show. But there are two challenges here: one is if you’d like the overlay itself to have some content which you want to conceal, i.e. which you want to get cut off while hiding it and not simply move along with the parent when animating it out. The other challenge is to add a rotation and guarantee that the overlay covers the whole screen so that no gaps are shown when you move it out. When combining these two effects, things get really interesting.

So let’s tackle these two challenges in this little tip today and show some of the many possibilities for how to use these techniques in a page design.

The demos are kindly sponsored by Northwestern: Earn your MS degree entirely online. If you would like to sponsor one of our demos, find out more here.

Attention: Highly experimental prototyping, please view in a capable browser.

The reveal effect

The beauty of the reveal effect is that the technique is very simple, yet the result is so interesting: take any element that has its overflow set to “hidden” and animate it in some direction, while animating its child in the opposite direction. This creates a “cut off” look, the content appears to be steady in one place, as if we’re animating some kind of clipping mask. Yet we are only translating elements.

Under the hood, you can see what’s happening here:

We simply move a container up. Now, let’s keep the content in place by reversing that movement and translating it in the opposite direction:

One last step is to add overflow: hidden to the parent:

And that’s it! Now, if you want to spice things up a bit, you can add a different duration or easing to the reverse element or other animations to the inner elements.

Adding a rotation

The effect becomes a little bit more complicated when we want to add a rotation. When we rotate an element it will create gaps and not cover the background entirely anymore. So we need to make sure that it’s width and height is set in such a way that when rotated, there are no gaps.

Technically, we’re want the (minimum) bounding box of a rotated rectangle.

The following Stackoverflow thread gave us the right formula for our case: How to scale a rotated rectangle to always fit another rectangle

We only need to find the correct width and height, so the following bit is interesting to us:

“When you rotate an axis-aligned rectangle of width w and height h by an angle ɸ, the width and height of the rotated rectangle’s axis-aligned bounding box are:

W = w·|cos ɸ| + h·|sin ɸ|
H = w·|sin ɸ| + h·|cos ɸ|

(The notation |x| denotes an absolute value.)”

Additionally, we have to make sure that we keep the previous structure in place and that we show the content straight. So we need to rotate the content back. To ease our animation and not tinker with calculations we avoid moving the rotated content, but instead we’ll use the resized container for the motion.

In total we will use three containers to achieve all that:

<div class=”content content–first”><!– only rotated –>
<div class=”content__move”><!– resized and moved –>
<div class=”content__reverse”><!– reverse rotation –>
<!– … –>
</div>
</div>
</div>

If you look at the x-ray view of one of the demos, you can see the rotation and calculation of the new width and height:

Given this structure, there are really endless possibilities for rotated reveal and overlay animations.

Think of multiple overlays. Think of matching animations of the elements that are being revealed or the ones that get hidden.

There’s so much to explore!

Have a look at our little compilation, we hope you enjoy it!
