There’s a lot to talk about Jamstack so let’s get right to it!


What Is Jamstack?

Jamstack emerged in 2016 when the concept of it was brought to the mainstream at Smashing Conf by Matt Biilmann, the co-founder and CEO of Netlify.

Since that time, Jamstack has evolved into a robust, cloud-native web development architecture that lets users deploy websites and apps with the best practices.

You can use it to build any type of website and app — a large site for an e-commerce platform, a blog for your product, content-rich websites or your personal website.

As Biilmann states, ‘JAM’ in Jamstack stands for “a modern web development architecture based on client-side JavaScript, reusable APIs, and prebuilt Markup.” But with the rich infrastructure possibilities, it’s a real powerhouse among web development architectures.

But that was simplified. Now, let’s get more technical.


Jamstack vs Other Web Development Stacks

Jamstack is a bit of a web development stack. The software development stack is a set of tools used to develop web apps and sites. While it may seem that there’s nothing special that distinguishes Jamstack from other frameworks, there actually is. And that is — Jamstack is static but at the same time, it’s dynamic.

In simple terms, its architecture uses Git workflows and modern tools to serve the pre-rendered content to a CDN and make it dynamic via APIs and serverless functions.

To sum it up, Jamstack gives you more elasticity in creating modern, user-friendly apps and websites. It also ensures that your customers and users will find it easy and inviting to move around your site or app.


How Does It All Work?

Understanding how Jamstack works may not be easy, especially for non-tech people. So let’s analyze the core functionalities to get to know it better and understand how exactly it works.

JavaScript

JavaScript (JS) is one of the most popular programming languages and core technologies of the WWW (World Wide Web). It’s also thought to be the best language for coding beginners.

Its power lies in giving life to web pages — JavaScript converts a static page into an interactive one. That helps to engage visitors and improves user experience.

In general, JS is a fundamental element for interactive websites and applications with dynamism.

What’s the difference between static and dynamic pages and why does it matter?

That’s the part where it’s worth mentioning the concept of static vs dynamic pages. Static pages are those with a fixed content that isn’t changed often, for example, blog posts. On the contrary, content on dynamic pages changes frequently, e.g., e-commerce websites, or weather pages.

How does it work on a technical level? When a server receives a request for a static web page, no additional processes take place. While when the server receives a request for a dynamic page, it adjusts to the user’s query.

Why is this important when talking about Jamstack? Because websites built on Jamstack are static files but the APIs are accessed via HTTPS with JavaScript and that enables the websites to be dynamic. Jamstack’s cornerstone is staticity that with the use of JavaScript and APIs, in the hands of the end-user, becomes a dynamic and interactive environment.

APIs

On Jamstack, the operations that can make a website dynamic are possible with the APIs — third-party services or your custom functionalities.

That’s what Jamstack uses, next to JavaScript, to enable web pages to be dynamic. APIs also give more flexibility to build different kinds of applications and make them more complex, functional, and accessible.

Headless CMS is also a large part of the Jamstack environment since it allows you to deliver content wherever you need and want to — not only to a templated site but even to many receivers at the same time, like e-stores or mobile apps.

Along with headless CMS, thanks to the connection to the data via API and receiving only the content part instead of the presentation part, you get the flexibility to choose your favorite front-end framework to build a site.

Applied Technologies

As you already know, Jamstack is not a tool in itself but an environment and set of standards according to which you create apps and websites.

And that’s what it’s known for — the use of technology to provide a flexible environment for website and app development.

In general, the content can be sent to a website in a different way and Jamstack uses markup. Markup is one of many ways you can choose to save the data, for example, a text on a website, so it can easily be delivered to the site. It’s like sending a package — you can send it via post-office, courier, or your favorite shipping company.

Mow, markup is possible thanks to decoupling (creating separate components to better adjust your content) and pre-rendering (preloading elements on the page for better speed — anything that isn’t generated in real-time).

With that, you can go to the final step — generating your site. Jamstack has integrated tools for that; they’re called Static Sites Generators (Next.js, Gatsby.js, Nuxt, etc.). They combine your content and template written in one of the frameworksinto files that can be deployed to a hosting environment as a ready-to-serve website.

Additionally, Jamstack has integrated tools for an automated git version control process. That’s important because you can easily save all versions of your code, all types of changes, easily backup all data, etc. As a result, all processes are smooth and effective.

All these components make Jamstack more comprehensible, adjustable, and faster.

The JAM

Let’s sum it up in short. All the above-mentioned components co-relate with each other and create a coherent unit. Jamstack wouldn’t exist without them all. Even though the framework is much powerful and extensive, the main features are its fundament around which you can freely navigate to get a stable, user-friendly CMS environment.


Why Use Jamstack—The Benefits

Jamstack has everything you need to provide a perfect user experience. It’s great for building simple apps as well as highly complex websites.

Here are the main benefits of Jamstack.

Jamstack


1. Better Performance

Jamstack doesn’t create pages in real-time but uses the pre-built content which makes the whole process faster.

Moreover, it serves your pre-built markup and all assets over a CDN (Content Delivery Network distributed in different geographical locations) which boosts the speed. CDNs are a great advantage because they can be close to the client or user which skyrockets the performance even more — there are fewer lags.

That gives you fast-loading pages, shorter response time, and largely improves user experience. Statistics show that 1 in 4 visitors would abandon a website that takes more than 4 seconds to load and 46% of users don’t revisit poorly performing websites. So if you care about page speed and UX, Jamstack will take care of it and reduce the bounce rate.

2. High Security

Jamstack is known for its security. Since you don’t need to operate a lot with code and store it on your servers, you can make sure it’s safe.

And the third-party apps used via the APIs lower the risk of attacks because all the work happens in their environment so everything is safe and sound.

3. Low Costs

When you build and deploy websites using the Jamstack approach, you lower the costs of maintenance. That’s because it’s much cheaper to operate on static files.

Also, the APIs allow you to save money on extra tools as you can use the third-party apps to deal with some of the aspects of DevOps and maintenance of the servers.

4. Scalability

There’s nothing better than Jamstack to make scalable, well-performing projects. Since it’s based on CDNs, hosting your website is a piece of cake. You don’t have to worry about traffic because your site is served to clients via local servers, which makes it easier to quickly reach users.

Think about it as a one-lane vs three-lane highway. It’s a breeze to unload the traffic on three-lanes rather than get stuck on the highly-jammed one.

There are no glitches, no errors, and end-users can enjoy a smooth and fast experience.

5. Better Developer Experience

Using old, heavy frameworks to develop an app or website is no longer a problem. Developers don’t have to focus on standard technologies that are hard to use and make it painful to create the end product.

Instead, they can incorporate their favorite tools and approaches for faster results and concentrate on what really matters.

6. Maintenance

In Jamstack, you operate directly within the infrastructure. It’s easier to keep it working smoothly without the need to constantly keep an eye on additional tools and other addons. The APIs are like the extensions to Jamstack and largely enhance work.

It’s easier to maintain it at a lower cost.

7. Flexibility

Because of the static-dynamic combination, Jamstack gives you a lot of flexibility. It’s more portable and allows you to choose the host you want to use to reach the public. You don’t need a single server to send your content into the aether.


Jamstack or WordPress — Which Is Better?

You may be wondering how is Jamstack better than the famous WordPress? Why should you even consider choosing Jamstack over the global leader used by millions of people?

WordPress is definitely a behemoth in the world of CMSs but don’t get discouraged by it when thinking about Jamstack. That’s because Jamstack has a huge advantage over WordPress in many aspects.


Jamstack


Fewer Glitches

If you’ve ever used WordPress, you know exactly it’s not perfect. It lacks coherence on many levels, beginning from themes structure, through missing functionalities, to random errors.

Often, you need to patch them with additional solutions or think about how to overcome them. And it’s not always easy.

Jamstack allows you to omit those glitches and creates a perfect environment to build a fully functional website.

Jamstack is More Secure

That’s probably one of the most important factors and definitely cuts above WordPress (and other web-building platforms).

A lot of people experience security breaches, hacking, and malware attacks that damage content or erase it. It’s also easy to get blacklisted by Google. That can cut you off from getting crawled by Google and gaining traffic to your website. In consequence, your business incurs serious losses.

Fewer surfaces make platforms built in the Jamstack ecosystem less vulnerable to external attacks and threats.

Faster Website Delivery

The pre-rendering that Jamstack is based on makes websites load much faster than when they’re based on a real-time content transfer.

So if you plan to include a lot of dynamic elements on your website, for example, videos or gifs, WordPress may slow it down and extend the loading time for your page.

Super SEO-friendly

The technical and security aspects highly influence your position in the search engines, especially when you experience security issues and have problems with the back-end development. Jamstack can help boost your online presence and skyrocket your performance.

Faster load time and static-dynamic structure with the pre-rendering make your website an easy setting for Google bots to crawl and put it high in rankings.

It’s Cheaper

We’ve already mentioned that the costs of maintenance are much lower when you build sites and apps in the Jamstack environment. You don’t have to invest in additional resources but can focus on the front-end processes.

Hence, if you want to cut costs on platform development and deployment, choose Jamstack over WordPress.


Best Practices for Jamstack

To make your work with Jamstack easier and more comfortable, its creators defined the best practices. If you apply them in building your web or app, you’ll find it easier to work in this specific ecosystem.

Let’s check them in short.

1. Base Your Project on CDN

Projects in Jamstack don’t have to be stored on a server but are served directly from CDNs. No single server is required and your websites load quickly and are scalable.

And that is the first best practice for using Jamstack to boost speed and improve user experience.

2. Use Build Tools

In Jamstack, the approach assumes that websites should be built with little effort. So instead of focusing on the tiresome back-end, developers can get straight to the point by automating work with modern build tools.

Such tools can help automate processes like compiling computer source code into binary code, packaging it, and running automated tests.

That helps to reduce repetitive tasks, improve the quality of the end product, and saves time and money. Moreover, dedicated tools make it possible to establish best practices for software delivery and continuous integration.

3. Automate Builds

Automating build processes that are clearly defined and scripted makes it easy to implement them. Whenever you need your content to go live, automated builds can do the job for you, so you don’t have to repeat the work.

4. Atomic Deploys

To keep consistency on your site and avoid glitches, Jamstack recommends atomic deploys. It’s a system that lets you deploy your content in a safe way — your website goes live only after all content is uploaded. It’s a good practice for large projects.

5. Cache Invalidations

Instant cache invalidation is a practice that ensures your content is live when you publish it. After your build is uploaded, the CDN invalidates its cache. This means that all your new builds are immediately live.

6. Git Version Control Systems

To simplify staging and testing workflows, and reduce contributor friction, you can freely work in version control systems such as Git.

You and your team can easily track and manage changes, improve teamwork, and work flexibly the way you or your team likes without the need to adjust to rigid frameworks. This ensures high-performing development, and your software team can work faster and more effectively with reduced development time and better deployments.

A Few Words on Jamstack Drawbacks

However great Jamstack sounds and seems, it has its disadvantages. For some, they may be smallish imperfections, but for others, they might be the bigger obstacle. That’s why it’s important to look at both the good and the bad sides to choose the right platform for your needs.

If you’re wondering what Jamstack lacks in its greatness, here’s a short list:

  1. Beginner unfriendly: if you’re familiar with WordPress, you may already know that you don’t need to be tech-savvy to use it. Jamstack, on the contrary, requires you to have some coding knowledge. For some people, it may be a big challenge and might require hiring professionals who can work in the Jamstack environment. In that case, you need to depend on developers to create a website.
  2. Complex API: unlike traditional CMS, Jamstack infrastructure may require you to use many different APIs just for one project. The environment is largely API-dependent and you need to be aware of that.
  3. Not suitable for real-time data: if you want to create a platform with content that updates in real-time like social media platforms, you’ll need to find a different solution.
  4. You need coding skills for updates: Jamstack is not as easy as WordPress and requires coding skills to change or update content.

Unless you have a team of developers or the right skills, you will get stuck at some point in using Jamstack to build an app or website. But don’t get discouraged, there are people that can help you build a perfect platform in the Jamstack environment.
