Are you confused about choosing the right architecture for your web application? This article will help you understand the key differences between the JAM stack and conventional web architectures, helping you make an informed decision regarding your web development architecture.
Evolution of Web Development
In the early days of the internet, web architecture was purely static. Websites created back then were only folders of static HTML and CSS files. A browser’s job was to let the user view the content based on these HTML and CSS files.
However, as the technologies evolved, they allowed us to create more advanced websites with the possibility of creating customized content. At that point, the HTML of a website had to be built at the time of request by a server.
Here’s how it used to work: A user requests a page, but instead of having it ready, the server consults the database and then presents the appropriate content to the user. There was an upside to this architecture, though. It allowed us to serve customized content based on the user’s requirements.
However, the major downside to this architecture was that it was slower than just having static HTML files. That’s because it only created each page upon request, which required more resources to build the right content.
Conventional Web Architecture
In a conventional web architecture – let’s say WordPress – the server receives a request. WordPress does some database queries to fetch the content, code, and data for your site and its plugins. It renders HTML and CSS and sends the result to the user. In other words, in conventional web architecture, the server handles each request separately and delivers the content to the user accordingly.
JAM Stack Web Architecture
The main reason for choosing it is to go as serverless as possible. That means taking away as many tasks as possible and pushing them to the client instead of the server for better performance and faster load time.
JAM stack has three core parts:
APIs: They replace the database and fetch everything you need directly from the services required.
Markup: It serves the actual website content and HTML.
The main difference between these two architectures is how tightly content, code, and designs are connected. With a conventional/legacy CMS, you handle everything in the same system, i.e., you have a back-end system where developers manage the code, design, and data. Moreover, your content is managed and created from the same interface and stored in a database. So, once a user requests a page, the back-end server assembles and delivers it to the user.
On the other hand, a JAM stack site works on the principles of decoupling and prerendering. In this setup, the server is only responsible for delivering static front-ends pre-generated at the build time. Therefore, you mostly rely on the client side instead of the server side.
Pros and Cons of Conventional Web Architecture
|Broad choice of open-source standards||Relies on monoliths|
|Works great for dynamic apps||Lacks in performance|
|Most stakeholders currently work in this ecosystem||Tightly coupled and hard to maintain|
Pros and Cons of JAM Stack Web Architecture
|It can be blazing fast||Not content editor friendly|
|Website is secure||Dependency on third-party services|
|Scaling is easy and cheap||Dynamic features require more heavy lifting|
|Better developer experience||Template changes require coding|
Is JAM Stack the future?
For the right project, the JAM stack is a good solution, and the decoupled architecture brings a lot of advantages to many websites. Right now, it’s still on the technical side, though, with both developers and editors needing certain technical skills to succeed. So, if your team does not possess the necessary skills to work efficiently with the JAM stack, you might not see the results you want.
But it doesn’t matter how fast a website is if your visitors see the same old content that editors find difficult to update. If you want to negate the primary con (the editor experience) of a JAM stack site, you should look at using a headless CMS with it. A headless CMS allows you to bank on a decoupled architecture with REST APIs that serve the content without adversely affecting the editor experience.
Therefore, we can safely conclude that the JAM stack web architecture is really the future of web development. Employ a headless CMS to overcome the limitations of the JAM stack architecture and build blazing-fast websites!
