Jamstack: Build Faster, More Secure Websites

Even if you’ve been working hard to optimize your website’s performance, you may not have considered the game-changing potential of Jamstack architecture.

Over the years of trying different Web development strategies, we have discovered that Jamstack can significantly improve a website’s performance in terms of speed, security, and scalability.

Jamstack is a modern web development architecture, that’s revolutionizing how we build and deploy websites.

Whether you’re a seasoned developer or just starting your web development journey, understanding Jamstack can give you a significant edge in creating fast-loading, highly secure websites.

In this comprehensive guide, we’ll explore what Jamstack is, how it works, why it’s gaining popularity, and how to use it to build better websites.

What is Jamstack?

Jamstack is a modern web development architecture based on client-side JavaScript, reusable APIs, and prebuilt Markup. The term “Jamstack” was coined by Mathias Biilmann, CEO of Netlify, in 2015.

It’s not a specific technology or framework, but rather an approach to building websites and apps that delivers better performance, higher security, lower cost of scaling, and a better developer experience.

The “JAM” in Jamstack stands for:

• JavaScript: Dynamic functionalities are handled by JavaScript, running entirely on the client side.
• APIs: Server-side processes are streamlined into reusable APIs, accessed via JavaScript over HTTPS.
• Markup: Websites are delivered as static HTML files, generated from source files (like Markdown) using a Static Site Generator.

What are the Benefits of Jamstack?

Jamstack offers a variety of advantages over traditional web development approaches:

• Faster Performance: One of the most significant advantages of Jamstack is speed. Jamstack sites serve pre-built markup and assets over a CDN, resulting in faster load times and improved user experience.
  As you know, website speed plays a crucial role in Search Engine Optimization (SEO). Faster websites rank better on search engines because they provide a better user experience.
• Improved Security: Jamstack offers a secure architecture by minimizing server-side components and using static assets. This reduces the attack surface and makes it more difficult for hackers to access your application.
• Scalability: Jamstack’s architecture and approach make it well-suited for building scalable web applications that can handle high traffic and growth
• Cost-Effective: Since Jamstack sites are static and don’t require real-time server resources for every request, they are often more cost-effective, and easy to host.
• Better Developer Experience: Jamstack improves the developer experience by allowing developers to focus on building features rather than maintaining complex server setups.
  You can easily integrate Jamstack applications or sites with third-party APIs to access data and functionality from external services.

How Jamstack Works

Jamstack operates by separating the front end and back end, allowing for a more modular and flexible development process. Here’s a simplified overview of how Jamstack works:

• Development: The front end of a Jamstack site is pre-built using a Static Site Generator (SSG) like Gatsby, Next.js, or Hugo, along with any necessary APIs. These tools take source files (e.g., Markdown, JavaScript, etc.) and generate static HTML files.
• Build: When changes are made, the SSG pre-renders the entire site into static HTML files. This pre-generation makes the content ready to be served as static files whenever a user visits the site.
• Deployment: Once the site is built, these static files (HTML, CSS, JavaScript) are deployed to a Content Delivery Network (CDN), making them available globally.
  A CDN is a system of distributed servers that delivers web content to users based on their geographic location.
• Runtime: When a user visits the site, they’re served static HTML, which loads quickly. Any dynamic functionality is handled by JavaScript, which can call APIs if needed.
  JavaScript makes your website more dynamic without slowing it down or compromising security.

What Are the Key Components of Jamstack

Jamstack architecture is built on three core components—JavaScript, APIs, and Markup—which work together to deliver fast, secure, and scalable websites. Let’s break down each of these components and other essential elements that contribute to Jamstack’s functionality.

Static Site Generators (SSGs):

Static site generators (SSGs) generate static HTML files from templates or markdown files. Some popular SSGs used with Jamstack include Gatsby, Next.js, Hugo, and Jekyll.

Headless CMS:

A Headless CMS is a content management system that delivers content via APIs rather than coupling it with a front-end display layer. Headless CMSs fit perfectly into the Jamstack architecture because they provide an easy way to manage content that can be fetched by the front end as needed. Some popular SSGs used with Jamstack include Contentful, Sanity, Strapi, and Ghost.

APIs:

Another crucial core component of Jamstack is APIs. Jamstack allows you to integrate third-party services through APIs. These APIs handle functionalities such as authentication, payments, and content management, offloading the heavy lifting to specialized services.

Here are examples of Common APIs:

• Stripe: Online payment processing for websites and apps.
• Auth0: User authentication and authorization as a service.
• Firebase Real-time databases and serverless backend
• CDN: A Content Delivery Network (CDN) is essential for distributing static files globally, ensuring that users can access the content quickly from the server closest to them. Jamstack sites rely on CDNs for fast load times and global distribution.

Version Control:

Git-based workflows are common in Jamstack development, often tied directly to deployment processes. They are used to track changes to your codebase, collaborate with others, and manage different versions of your project.

By combining these components, Jamstack allows you to build highly scalable, performant, and secure web applications.
