This is the fourth and final post in our series on how you, the developer, can build or improve your company’s notification system. It follows the first post about identifying user requirements, the second about designing with scalability and reliability in mind, and the third about setting up routing and preferences. In this piece, we will learn about using observability and analytics to set your system and company up for success.

Developing an application can often feel like you’re building in the dark. Even after development, gathering and organizing performance data is invaluable for ongoing maintenance. This is where observability comes in—it’s the ability to monitor your application’s operation and understand what it’s doing. With close monitoring, observability is a superpower that allows developers to use various data points to foresee potential errors or outages and make informed decisions to prevent these from occurring.

Data is a piece or a large amount of information stored electronically. With so much information stored in different folders, this separation of data makes data storage inconsistent and tedious to access, edit, or replace.

That’s exactly where servers or databases come into the picture. With complex data and numbers pouring in on a daily basis, having a strong database or servers is crucial to managing it. A database is nothing but a collection of information in a structured way to allow for prompt readability, access, and editing. It is the center of the flow of data, as data flows from the database to other parts of the system.

Article Image Life was normal until 2020’s monstrously bad news – Covid – came around. Developers got out of bed, then marched to the office to crunch code as they always do. While inside of the office, they reviewed their goals, played with Git, interacted with their colleagues over a cup (or two) of coffee, and built products relevant to the functionality of the company. Many developers also had side-projects that they would go home and work on during their free time as their hobby.

While in the office, developers would be busy regurgitating code – web developers, for example, would work with PHP, SQL, CSS, Javascript, and its libraries (say, jQuery). Meanwhile, database administrators would think deeply about the performance of their database instances (they would take care of indexing and normalizing their data, or work with big data sets, etc.). Once the code was complete, they’d document it and push it over to GitHub.

Websites as we know them are going to change very soon. The days of text, images, and basic interactions in a 2D browser window have served us well, but virtual, augmented, and mixed reality experiences are getting better all the time. Developers and designers need to think beyond the browser window and prepare for an immersive future.

Many have been very skeptical about VR and AR in the past because despite grand promises about what they would achieve, they’ve mostly failed to deliver on the scale that the industry hoped for.

But it’s different this time: industry leaders like Meta, Apple, and Microsoft are pursuing a range of different mixed reality projects; they see the opportunity and are dropping hints about what’s next.

In a survey from Perkins Coie LLP and the XR Association, nearly 9 in 10 respondents said that by the year 2025, immersive technologies—including augmented reality, virtual reality, and mixed reality — will be as ubiquitous as mobile devices.

That’s a bold prediction, but it could be our new reality.

Use Cases

VR and AR aren’t a logical fit for every website, and that’s fine. There’s no need to force an immersive experience on something better suited to a standard viewing experience.

But when they’re done right, 3D experiences can add a lot to your website. Check out the demo experience from Mozilla, the 3D tours from Matterport, and the immersive storytelling from Within.

Here are a few areas where these technologies shine:

  • Retail – VR can be used to provide a virtual showroom where customers browse through products. AR can even bring the products into your home by showing you how a piece of furniture will fit in your room, what a painting will look like on your wall, or in Apple’s case, how a product will look on your desk.
  • News – Coverage of events can be enriched by providing a 360-degree view and placing viewers in the center of the story.
  • Training – AR can generate virtual overlays over physical equipment so employees can have hands-on training that’s more effective.

Define Your Platform

Adding immersive experiences to your website will require various skills based on what you’re trying to create. Whether you’re new to web development or are a seasoned developer with many years of experience, the main difference from classic web development is that you’re switching from a 2D to a 3D experience. Development in VR/AR is much closer to developing 3D video games than creating web applications.

First of all, you need to decide on the hardware that you’re building for. Are your viewers mainly using computers, smartphones, or a headset like the Oculus Quest? Each hardware category offers a different set of capabilities for what’s possible.

Next, when we look at 3D engines and frameworks on the market, some big names like Unity, Unreal Engine, and CRYENGINE stand out. Most of these engines were spun out of game development and are based on programming languages like C, C++, or C#. While very powerful, they’re overkill for anyone trying to create a basic immersive web experience.

The good news for web developers is that the WebXR Device API is an open standard specified by the W3C with a JavaScript API that makes immersive experiences possible in the browser. So if you already have a background in web development, you can use your knowledge of JavaScript to get started.

There are some useful frameworks and platforms that make working with WebXR more convenient:

  • A-Frame – A web framework for building 3D experiences.
  • React 360 – A framework for the creation of interactive 360-degree experiences that run in the web browser. As the name already suggests, it builds on React and reuses the concepts you already know.
  • Amazon Sumerian – A managed service that lets you create and run 3D, AR, and VR applications. Since it’s integrated into the AWS ecosystem, it’s also possible to add AI-enabled elements into your generated world.

Create Your Content

No one wants to read long blocks of text in 3D. Since we’re talking about visual experiences, it’s logical that the emphasis should be on creating content that is pleasing to the eye and interesting to look at. What works on a normal website probably isn’t going to feel natural in a 3D environment, so you need to decide what visuals you should create to suit the format.

What high-resolution images and assets do you need? Can you add videos? How about 360-degree videos? Will viewers just be looking at something, or will they be able to interact with it?

You also can’t forget about sound because it’s a critical part of immersive experiences. What music and sounds should you create to make the content come alive?

Not everyone is going to have the latest and greatest device or 5G coverage. The requirements for bandwidth and transmission quality are much higher with 3D content. A few milliseconds of latency can go unnoticed on a typical website, but in a VR/AR setting, it can make the experience laggy or unusable.

Try to optimize your content to be the highest quality it can be within a reasonable file size. If the experience starts to suffer from too many assets downloading at the same time, it’s better to create a more streamlined experience that maintains a high performance rate.

It’s important to consider your hosting infrastructure, as well. This shouldn’t be a big problem, but it is worth mentioning that you need to add new content types to your configurations, and your CDN needs to support these new types, too.

Make Your Content Flexible

When we’re talking about getting your website ready for immersive experiences, we’re not just talking about having people scroll through your regular website in VR. That isn’t compelling for your audience.

The idea is to take some content that’s already on your website and separate it from the presentation layer so you can use it in a 3D environment or any other platform that you want. Classic content management takes place in silos, which means you cannot easily reuse the content from your website.

This separation can be achieved by using a classic database, but if you want developers and content teams to collaborate, a headless CMS is front-end agnostic and more user friendly.

Start Experimenting Today

Building 3D content experiences may seem intimidating, but as we’ve seen, you likely already have the web development skills necessary to get started and try out some different ideas.

What you build today will prepare you for the 3D future of tomorrow.

Jamstack (JAMstack), is one of the most popular (and rapidly growing) tools for app and website creation. A unique ecosystem of functionality, Jamstack promises developers the support they need to create powerful websites and progressive applications. 

For a while, Jamstack was mostly written off as just another buzzword in the developer space. However, today, it’s growing to become a powerful investment for many business leaders. Even big companies are getting involved, like Cloudflare, with Cloudflare pages, and Microsoft with Azure Static Web Apps. Elsewhere, we’ve seen brands like Shopify, PayPal, and Nike getting involved too.

So, what exactly is Jamstack, and is it time you transitioned over? Let’s find out…

What is Jamstack?

Jamstack, otherwise known as “JAMstack,” is the name of a developer ecosystem made up of JavaScript, APIs, and Markup (hence: JAM). The solution is a web development architecture allowing developers to access static website benefits, such as higher security and better performance, while still unlocking dynamic database-oriented CMS.

The Jamstack solution allows companies and developers to build a dynamic website where real assets are pre-rendered static files in a CDN. The dynamic environment runs on JavaScript client-side, through serverless functions. 

For a better insight, let’s compare Jamstack to the LAMP stack development strategy, which originated from the four open-source components many developers used to build sites: Linux, Apache HTTP, MySQL, and PHP.

With LAMP, each user request for a page forces the server to query a database — unless the page is cached — and combine the result with page markup data and plugins. Jamstack websites serve pre-built optimized assets and markup solutions quickly because the files are already compiled on a CDN. There’s no need to query the database. 

Jamstack workflows dramatically reduce cumbersome issues with development and excess maintenance, making them highly appealing to developers. 

What Are the Benefits of Jamstack?

Jamstack won’t be the ideal development tool for everyone, but it has a lot of benefits to offer. By fetching HTML from a CDN, the system doesn’t have to wait for HTML to be combined and returned to clients. The solution also provides an improved developer experience with static methods. 

Using Jamstack, developers can build fantastic static files ready to serve by request, hosted on a global CDN. Some of the biggest benefits of Jamstack include:

  • Performance: Because you’re serving pre-built static files from a CDN directly, you’ll achieve much faster loading times, unmatched by typical server-side rendering options. Because you’re serving static files, you’re also better equipped to handle any traffic spikes you might encounter, with minimal slowdown.
  • User experience: Better website performance significantly improves user experience and website traffic, as well as SEO efforts. User experience has always been a critical factor in ensuring the success of a website, and it’s essential to keeping your customers around for as long as possible. Websites optimized for performance will always delight users. 
  • Security: With Jamstack, there are no servers or databases to worry about. You use third-party solutions to handle these issues for you. The architecture of Jamstack means the back and front end of your development processes are decoupled, and you can rely on APIs to run server-side processes easily. Jamstack also comes with security benefits other approaches can lack. Clear separation of services is essential here. 
  • Hosting and scaling: Scaling and hosting can often be problematic in the development world, but because you’re serving files from a CDN, you’re less likely to encounter issues. CDNs are almost infinitely scalable, so you get excellent extensibility built into your development environment. CDN hosting for static files is also cheaper than traditional hosting, so you can keep costs low. 
  • Maintenance: Jamstack makes it easy to push your front end to the edge rather than managing infrastructure directly. Ditching plugins, databases, and other hosting services can help you to save more time and money on a significant scale. 
  • Developer experience: From a developer perspective, there are tons of benefits from Jamstack. You get the ease of a Github, CI/CD, CDN flow, and auto previews with simple rollback to reduce the need for backups. Local developer environments and the ability to run and debug cloud functions locally are all fantastic.

Does Jamstack Have any Limitations?

In a lot of ways, Jamstack is an innovative and revolutionary solution for development. It can help you to create a far more engaging website and present your company in an incredible way. Of course, that doesn’t mean there are no limitations to be aware of. 

Jamstack is developer-friendly, for instance, but it’s not beginner-friendly. You will need at least some knowledge of web development to start unlocking the benefits. You’ll need to understand things like Vue or React, but you should develop a tool anyone can use with a bit of work.

There’s also a handful of things you can’t pre-generate, like user-specific and real-time data. So, this means you may not be able to use Jamstack effectively on projects requiring these kinds of data. Building an analytics dashboard, for instance, probably isn’t a good idea with Jamstack. Other issues for some developers may include:

  • API complexity: It can be overwhelming to try and find the right solution for your needs among so many different options. Of course, this could also be something you’d say about the WordPress ecosystem and its huge variety of plugins. An API usually won’t break your production website, at least. 
  • Long building processes: If you have a large number of pages, there’s more likely to be an extensive building process to think about. Whenever you make a change to a single page, even a little one, you’ll need to rebuild your entire website. This is a problem if you run into a website with thousands of pages. There are solutions to this problem available, however.
  • Handling dynamics: Going with Jamstack doesn’t mean abandoning your backend. An important part of the approach is accessing serverless functions, which are becoming more effective over time. These serverless functions can also be executed on the edge. The backend parts of your website will require regular maintenance as they scale.

Best Jamstack Tools to Check Out

Now you know the basics of Jamstack, let’s look at some of the tools you can use to design an incredible website or application within the Jamstack environment. 

The Git Tool Landscape

There are tons of tools within the Git ecosystem common among Jamstack developers. Starting with Git itself. Git represents a powerful free, and open-sourced distributed version control system. With this solution, companies can handle everything from small to enterprise-level projects with efficiency and speed. The solution is extremely easy to use and learn, and outclasses a range of tools like Perforce, ClearCase and Subversion. 

GitHub Pages and GitLab pages are two hosting services for Git repositories with built-in services to host static pages from out of your codebase. This makes the two solutions fantastic for when you’re building a Jamstack website. You can access the functionality for free too. 

GitLab gives you a comprehensive DevOps platform to work with, where you can enjoy a comprehensive CI/CD toolchain out of the box. The comprehensive solution, delivered as a single application, changes the way security, development, and Ops teams integrate and collaborate. Gitlab helps to accelerate software delivery on a massive scale.

AWS Amplify

AWS Amplify, created by Amazon Web Services, is a development platform packed full of useful features for people in the Jamstack environment. The Amplify offering aims to reduce the complexities associated with Amazon Web Services for mobile and web deployment. You get 12 months of hosting for free with new accounts, and you get Storage with Amplify too. 

The Amazon Amplify solution dramatically improves the regular AWS workflow, especially if you’re just a novice user. There’s a huge documentation hub to help you too, which is way more convenient than Amazon’s usual documentation solutions. Amplify is still accessed from a somewhat bloated console, however. 

With AWS Amplify, companies can access features like a comprehensive data store to sync data between the cloud and websites. There’s also easy-to-use interface access across all different categories of cloud operations. The service works well with a range of JavaScript central tools. 

Netlify

Netlify is a pioneering solution in the Jamstack environment, allowing users to go dynamic with their websites and applications on their own terms. You can access a range of add-ons and integration, access your favorite tools, and make your own. The flexible environment enables developers to run websites on a multi-cloud infrastructure designed for speed and scale automation. 

Built to be entirely secure from the ground up, Netlify makes it easy to build a site that’s custom-made for performance and deployed directly. You don’t need to worry about managing, scaling and patching web services, which means you can more quickly implement your Jamstack architecture. 

Unlike other large legacy apps, Jamstack projects are neatly separate from your front-end pages and UI from the backend databases and apps with Netlify. Using this service, the entire front-end can be pre-built with highly optimized static assets and pages, and developers can deliver new web projects faster than ever before.

Next.JS

Inspired by the functionality of PHP, Next.JS is a solution for pre-rendered JavaScript modules. The solution allows developers to easily export the components of their apps and perform individual tests to determine how each element works. You can also access a wide range of components and modules from NPM. The Next offering allows developers to save time, removing the need to use webpack bundles and transform with compilers. 

The full solution is extremely intuitive, ensuring developers can create solutions quickly. What’s more, the technology you build will allow you to load only the bundle needed from your JavaScript workflow, rather than all the JavaScript at once. Pre-fetching, one of the features of Next.JS, also picks up where standard code-splitting leaves off, allowing for optimized bundles of code to load seamlessly. 

Next.JS also supports hot-module replacement. This means instead of reloading an entire application when you change the code, you only recreate the modules you’ve altered.

Angular

Probably the most widely-recognized of all the JavaScript frameworks, Angular, designed by Google engineers, appeared first in 2012, offering developers a new way to create dynamic pages. Before this technology, there were other opportunities for creating dynamic pages, but they were nowhere near as convenient or speedy. 

Angular is probably one of the most essential tools companies can use when building a Jamstack website or environment. The front-end web development tool attracts developers from all over the world. Every version is packed with features and constantly upgraded to ensure you can generate the best results. 

Angular extends HTML file functionality with powerful directives, and it requires very little effort to enable these directives too. All you do is add the ng- prefix to your HTML attributes and you’re ready to go. Angular also allows developers to create widgets leveraging editable data with two-way binding. This means developers don’t have to write code that syncs constantly between the model and view. 

With Angular, developers also get access to things like virtual scrolling, which can help with displaying large lists of elements performantly, rendering on the items that fit on the screen to reduce loading times. 

React

Another must-have tool in the JavaScript world for Jamstack, the React solution was launched first in 2013, and has won thousands of customers across the globe thanks to fantastic functionality. Today, the full landscape is maintained by Facebook, along with all the members of the standard developer community. The solution is used by some of the biggest giants in the tech industry, like Netflix, PayPal, and Apple. 

React is a true pioneer in the Jamstack ecosystem, with its sensational approach to simple and straightforward solutions for JavaScript management. You’ll be able to access batched and virtual DOM updates, which makes it easier to unlock components quickly, and write your components the way you see them. There’s also the added benefit that React is compatible with a lot of tools. 

You can build a comprehensive app or website with the help of React, and you’ll have no trouble accessing some of the top features, particularly with plenty of support available from the React community. 

Gatsby

Created from the ground up to improve user experience on a comprehensive level, Gatsby is a static site generator with heavy focus on things like SEO, performance, and accessibility. The solution offers plenty of out-of-the-box features to help developers deliver the most immersive solution for their users, without unnecessary complexity. 

Gatsby users pre-configuration to develop static websites giving developers faster loading pages, stronger code splitting, and server-side rendering. You can also access features like data prefetching, asset optimization, and quick image loading. Gatsby boasts excellent documentation and starter packs to help you get your site up and running more quickly.

The GraphQL data layer of Gatsby also means the system can collect your data from anywhere, including your CMS, JSON, Markdown, and APIs. More than just your standard site generator, this is a tool built specifically with performance in mind. 

Agility CMS

Developing an effective Jamstack website means having access to the right CMS technology. Agility CMS wasn’t the first CMS solution to support Jamstack, but it is one of the better-known options. As one of the first headless CMS solutions to hit the market, the company has quickly captured the attention of a huge range of developers worldwide.

Agility CMS is a Jamstack pioneer, capable of helping developers to build a foundation for any online ecosystem. The technology is an API-first CMS with support for REST APIs, so developers can connect all the third-party apps and front-end frameworks they like.

The technology also gives developers the freedom to code their solutions their way. You don’t have to follow a specific set of guidelines for how content is created, but templates are available to fast-track development. Agility CMS also hosts and abstracts your database, so you don’t have to worry about connection strings, backups, and maintenance. 

With a strong content architecture to help companies manage digital content and a partnership with Gatsby, Agility is ideal for Jamstack development strategies. 

Building Your Jamstack Website

The Jamstack solution is more than just a buzzword in today’s development world. This unique approach to building incredible development experiences delivers an excellent advantage to both developers and their end-users. Fast, scalable, and full of solutions for customization, Jamstack is a powerful way to bring websites to life with simplicity and speed. 

Every day, more companies take advantage of the Jamstack environment, and we’re constantly seeing a wide selection of new tools, APIs and offerings emerging to help enhance the Jamstack landscape too. This environment is definitely worth consideration for any developer looking to significantly speed up their development strategy.
