In recent years, the landscape of web development has witnessed a paradigm shift through the widespread adoption of client-server architecture. This architectural approach allows developers to leverage databases to store content and clients to request data from servers. Furthermore, the advent of technologies like React, Angular, and Vue has introduced key concepts such as virtual DOM, JSX, rerendering, two-way binding, and more, thereby reshaping the industry’s jargon.
These concepts have empowered web applications, equipping them with a vast array of technologies and tools to seamlessly integrate with databases and servers. However, this newfound power also brought complexity to the process of web application development. Developers found themselves immersed in the intricacies of installing and configuring numerous tools, resulting in substantial development hours and delayed product launches.
Amidst this complexity, the need for standardized best practices and architectural guidance emerged, giving rise to a contemporary opinionated architecture known as Jamstack. Frameworks like Next.js, Gatsby, and Hugo have effectively harnessed the potential of Jamstack, introducing novel concepts such as incremental site regeneration, TypeScript support, intelligent bundling, and route pre-fetching.
The concept of Jamstack found its roots in the popularity of static websites around 2015, driven by technologies like Jekyll. The term “Jamstack” was coined in the same year by Mathias Biilmann and Chris Bach from Netlify. So, what exactly is Jamstack?
According to Mathias Biilmann, the CEO and Co-Founder of Netlify, Jamstack is “A modern web development architecture based on client-side JavaScript, reusable APIs, and prebuilt Markup.” In essence, Jamstack revolves around JavaScript, API usage, and Markup. While each of these elements is not new in the realm of web technologies, Jamstack introduces a fresh approach to their combined utilization.
To delve deeper into the technical foundations of Jamstack, we must examine the core elements that power this modern web architecture:
JavaScript forms the bedrock of Jamstack website development. Just as JavaScript enables dynamic behavior and logic in traditional web development, it plays a pivotal role in the Jamstack approach. However, what sets Jamstack apart is its complete decoupling of content from the frontend technology. This decoupling liberates developers, allowing them to utilize various frontend technologies, be it JavaScript frameworks like React, or even languages like Python or Go.
Jamstack’s flexibility in frontend technology choice empowers developers to make selections that align with project-specific needs.
In the world of client-server interactions, Application Programming Interfaces (APIs) serve as a fundamental tool. These APIs, whether implemented through GRPC, GraphQL, or REST, offer a seamless channel for communication between clients and servers. For instance, when a user requests information, the server responds with JSON data.
In the Jamstack paradigm, server-side actions are abstracted into reusable APIs accessible through JavaScript over HTTPS. This shift of workload to the client side eliminates the need for extensive server-side processing. Developers can leverage custom functions or third-party services to implement these APIs, broadening the possibilities for integrations.
The third critical element of Jamstack is markup. Traditionally, when a user requests content, the server goes through a sequence of steps to find and construct the requested information. This can result in considerable wait times for users.
Jamstack introduces a more efficient approach by utilizing prebuilt markup. Instead of relying on server-side construction of content, prebuilt HTML is generated using static site generators. These prebuilt HTML pages are hosted on Content Delivery Networks (CDNs), ensuring rapid and efficient content delivery.
There exists a vast array of static site generators, with over 300 options available for developers to choose from.
Before the introduction of HTML, CSS, and JavaScript, websites primarily existed in a static form. However, the evolution of web development led to the creation of dynamic webpages, where server-side operations handled content delivery.
Jamstack emerged as a response to the increasing complexity of web development. In the Jamstack approach, developers write code using JavaScript or other compatible frameworks. This code is then pushed to a source repository, such as Git, from which it is automatically distributed to a Content Delivery Network (CDN). This process harnesses the pre-rendering capabilities of Jamstack.
A CDN, akin to a network of servers distributed across the globe, ensures rapid and efficient website loading.
Jamstack offers a multitude of benefits that render it a compelling choice for various web projects. These advantages include:
Jamstack’s versatility extends beyond static websites. While it excels at building static pages, it can also accommodate dynamic websites that are presented as static pages. This unique feature sets Jamstack apart from traditional web development frameworks. Static websites built with Jamstack benefit from faster loading times and enhanced SEO friendliness.
Jamstack leverages static site generators, which take content or templates as inputs and produce prebuilt markup. This prebuilt markup is then distributed through a CDN. As a result, when a user requests information, the CDN delivers pre-rendered pages swiftly, streamlining the content delivery process.
CDNs operate by distributing website content across numerous server clusters, ensuring that content is served from the nearest server to the user, leading to faster response times.
Jamstack websites and web applications are not hosted on traditional servers. Instead, they are directly served through CDNs, substantially reducing hosting costs. Additionally, automated website updates simplify the maintenance process. Several CDNs, including Cloudflare, offer generous free trials, and support for Continuous Integration/Continuous Deployment (CI/CD) pipelines through Github, further enhancing the cost-effectiveness of Jamstack development.
Traditional server-side applications can be vulnerable to various security threats due to the multitude of APIs employed for content transfer to the server. In contrast, CDNs hosting Jamstack websites primarily contain read-only files with no active connections, minimizing the risk of exploitation by malicious actors.
Jamstack eliminates the need for physical servers, and website updates are predominantly automated. Scaling websites becomes a straightforward process, requiring updates based on the chosen tech stack. The absence of complex logic, coupled with content stored in CDNs, obviates the necessity for running servers, simplifying scalability.
Considering the array of benefits associated with Jamstack, it is a compelling choice for content-heavy projects. The broad compatibility of Jamstack with various technologies, frameworks, and APIs reduces the learning curve. If you are already familiar with technologies like React and GraphQL, transitioning to Jamstack should be relatively seamless. Even if you have expertise in other technologies, you can adapt similar approaches to incorporate them into your Jamstack projects.
Ultimately, Jamstack empowers websites to perform efficiently, load quickly, ensure security, and scale seamlessly. Two prominent frameworks that harness the power of Jamstack are Gatsby and Next.js. With these frameworks, you can generate pixel-perfect, highly extendable code directly from Figma and Adobe XD designs using the Locofy.ai plugin. This plugin streamlines the process of breaking down designs into components, making it easy to integrate a Content Management System (CMS).
