Did you know that Slack can be programmed to unfurl your website links and add rich information to them? Not only will it add rich information, but it will also drive more conversions. This Thought will show you exactly how to do it and how to replicate it. Let's take a dive.

I know you know how to use Open Graph tags to create rich previews. That's awesome. You can use og:title, og:description and og:image to create a preview like the one below.

Let's throw in some custom label meta tags in our page's <head> and see what happens.

That's nice. Not only does the reader have a good look of your preview, but they also get some insights in the unfurl about the reading time and category of the article. This makes the link more tappable and yields great conversions.

The Code Cakery

A recipe on making richer link unfurls on Slack.

Instagram has over 400 million active users, which is more than that of Twitter. This presents a huge opportunity for brands to market themselves through the visual platform. If you haven't been taking advantage of it, you should!

Those who know me know that I am obsessed with crafting delightful user experiences. As much as value this feature holds for marketers, it also vouches for a pleasing UX. This blog is a rundown of how developers can let users share content on Instagram using deep links. I am assuming you have a new SwiftUI project set up. Let's get coding.

Ollivanders is a wand shop founded in 382 B.C, located in Diagon Alley South Side in London, England. It is owned by the Ollivander family, widely acknowledged to be the best wandmakers in Great Britain. As bizarre as it may sound, this Harry Potter Wand Shop wants the wizards to easily share amazing stickers of their wands across Instagram – in the hope to gain massive virality.

To start with, let's create a model that fits this demo. I'd call it Wand. Each wand will have a name and stickerAsset.

struct Wand {
  let name: String
  let stickerAsset: String
}

While we are at it, we shall also create some mock data on wands. Here are some assets that we will be using in this demo – best to drag them into your Assets.xcassets right away.

fileprivate let wands: [Wand] = [
  Wand(name: "Dumbledore's Wand", stickerAsset: "dumbledore"),
  Wand(name: "Potter's Wand", stickerAsset: "potter"),
  Wand(name: "Granger's Wand", stickerAsset: "granger")
]

I'll also create a NavigationView and embed a List in it to have some barebones of UI. Nothing fancy.

struct ContentView: View {
  var body: some View {
	NavigationView {
		List(wands, id: \.name){ wand in
		  Text(wand.name)
	    }
		.navigationBarTitle(Text("Ollivanders"), displayMode: .inline)
	}
  }
}

Not bad, SwiftUI. Now that we have all this done, let's get to the real thing. We shall write some functions to implement deep linking to Instagram Stories.

struct ContentView: View {
    
    func shareToInstagramStories(
        stickerImage: String,
        backgroundTopColor: String = "#7F0909",
        backgroundBottomColor: String = "#303030"
    ) {
        // 1. Get a data object of our UIImage...
        let stickerImageData = UIImage(named: stickerImage)?.pngData()
        
        // 2. Verify if we are able to open instagram-stories URL schema.
        // If we are able to, let's add our Sticker image to UIPasteboard.

        let urlScheme = URL(string: "instagram-stories://share?source_application=\(Bundle.main.bundleIdentifier ?? "")")
        
        if let urlScheme = urlScheme {
            if UIApplication.shared.canOpenURL(urlScheme) {
                
                var pasteboardItems: [[String : Any]]? = nil
                if let stickerImageData = stickerImageData {
                    pasteboardItems = [
                        [
                            "com.instagram.sharedSticker.stickerImage": stickerImageData,
                            "com.instagram.sharedSticker.backgroundTopColor": backgroundTopColor,
                            "com.instagram.sharedSticker.backgroundBottomColor": backgroundBottomColor
                        ]
                    ]
                }
                
                // We'll expire these pasteboard items in 5 minutes...
                let pasteboardOptions = [
                    UIPasteboard.OptionsKey.expirationDate: Date().addingTimeInterval(60 * 5)
                ]
                
                if let pasteboardItems = pasteboardItems {
                    UIPasteboard.general.setItems(pasteboardItems, options: pasteboardOptions)
                }
                
                // 3. Try opening the URL...
                UIApplication.shared.open(urlScheme, options: [:], completionHandler: nil)
            } else {
                // App may not be installed. Handle those errors here...
                print("Something went wrong. Maybe Instagram is not installed on this device?")
            }
        }
    }
    
    var body: some View {
        NavigationView {
            List(wands, id: \.name){ wand in
                Text(wand.name).onTapGesture {
                    shareToInstagramStories(stickerImage: wand.stickerAsset)
                }
            }
            .navigationBarTitle(Text("Ollivanders"), displayMode: .inline)
        }
    }
}

We check if we can open the instagram-stories URL scheme with our application

If we can, we move on to create items for UIPasteboard

Once we have those items on UIPasteboard, we go further and open the URL

If all goes well, Instagram will take things from here and make a sticker out of the asset image.

We will also add things in Info.plist to let iOS know it is okay for us to open the instagram-stories URL scheme.

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>instagram-stories</string>
</array>

Phew. That's it. Let's see this badass in action.

That's pretty much there is to sharing to Instagram Stories. In production, you can get the image with an API call. This image can be generated at the back using Puppeteer or Jimp or any other tool at your disposal. You can also generate the image on-device using CGContext. I'll leave those details to you.

A rundown on posting your app's content to Instagram Stories.

Sharing to Instagram Stories – a definitive guide

Walk into a room full of Web developers (which is rare – web devs don’t get along, mainly because they are MEAN. *pun intended*) and you will likely be bombarded with mentions of Node.js, Angular or React.

All these modern Web technologies are built upon the basic structure of MVC architectural pattern. Lettuce taco about it *huehuehue*.

Model: Structures your data in a reliable form and prepares it based on controller’s instructions

View: Displays data to user in easy-to-understand format, based on the user’s actions

Controller: Takes in user commands, sends commands to the model for data updates, sends instructions to view to update interface.

Let me draw MVC like one of my French girls.

It is finally Taco Tuesday, and you walk to the waitress. You finally catch a breathe and blurt out, “One Double Decker Chicken Supreme Taco with extra cheese, please!”

You are the user, and your taco order is the request. To you, the Double Decker Chicken Supreme Taco is your favourite taco, and you pretty reliably know that this will be an ultra spicy, will-regret-in-the-morning but worth-the-money taco.

To the waitress, the Double Decker Chicken Supreme Taco is merely a series of steps:

The waitress’s brain is the controller. As soon as you say the word “Double Decker Chicken Supreme Taco” in a language that they understand, the work begins. This work is similar in nature to making a Soft Taco or Fiery Taco, but uses distinct ingredients that will never be confused. This limited tool set is the model, and includes the following:

Finally, the finished taco that you gorge upon is the view. The view is built out of the limited options from the model, and arranged via the controller (that is, the waitress’s brain).

Here is how the same process plays out in a modern web app:

The user makes a request along a route, `let’s say /about.`

The controller receives this request and gives a specific set of orders that are related to that route. These instructions could be for the model to perform specific logic.

The model carries out the logic, pulls from a database and sends back a response based on the controller’s instructions.

The controller then passes this data to the view to update the user interface.

If you have been to a taco shop, then MVC ain’t that hard.

Ishan heads the Web team at Incredible and enjoys building things that live on the internet. He develops exceptional websites and web apps that provide intuitive, pixel-perfect user interfaces with efficient and modern backends.

Talking in the third person about himself makes him uncomfortable.

He graduated from SRMIST, Chennai in Jul, 2021 (He feels so old now). Ishan passed the torch on to his juniors at SRMKZILLA – the official Mozilla Campus Club of SRMIST where he used to break builds (especially on Fridays) with some really cool people. He also volunteered and lead everything software at Aaruush. He used to lead the Technical team at DSC SRM – powered by Google Developers where he worked on a wide variety of interesting and meaningful projects on a daily basis.

TL;DR: He ardours software and toils to craft beautiful, beautiful products that don't come with manuals.

Ishan wants a doggo but is unlikely to get one (cc: Paapa).

Spacewalk – Swift Student Challenge – WWDC21

Spacewalk is the story of Edward Baldwin and his exhilarating space endeavour. While growing up, Edward aspired to be an astronaut and he fantasized and dreamt of walking in space and dancing amidst the stars.

It was a fairy tale start to Edward's career, as his talent and skills dazzled NASA to recruit him as their youngest ever astronaut. Edward was all set to be a legend, but fate has its course. He was struck by a disaster during his first spacewalk.

A gaping snag in the mechanical assembly cut him loose into space, floating further and further away from the spaceship deep into the vicious galaxy.

The game is not over for Edward, the ray of hope is still alive. If you are gamed to bring back Edward, help him aim and shoot the laser light towards his crew to bring him back to safety. But don't take it easy, space is full of surprises!

Ishan Chhabra

A space game which tests your understanding of concepts of reflection of light to bring Edward back to safety.
