JAMstack is changing the way we build websites. It breaks away from traditional CMS platforms to provide a solution that’s quick, secure, stable and scalable.

What is JAMstack?

JAMstack is an acronym that stands for JavaScript, Application Programming Interfaces (APIs), and Markup. It’s an architecture rather than a programming language or tool.

It’s a combination of these three aspects that are handled separately, but come together at the end (i.e. when a user interacts with a web page).

What the three components do:

JavaScript is the web’s programming language.

Application Programming Interfaces (APIs) are software intermediaries that enable two applications to speak to one another. 

Markup is the HTML web code (your content) which is generated in advance.

This means that with JAMstack websites, the frontend and backend are separated, so the various elements can be worked on independently. Content is generated in advance, in the form of static files. 

This pre-built content is then pushed to, and delivered from, a content delivery network (CDN): a global network of servers and data points that work together to bring everything closer to your website user. 

Check out Cobiro’s guide to JAMstack for a more in-depth explanation about how everything fits together.

Benefits of JAMstack sites:

Speed: pages are deployed from a server close to where the user is based, making page loads super fast.

Security: JAMstack websites are a lot less exposed as everything is worked on independently. 

Stability: complex work is done before the build, so any issues are dealt with in advance.

Scalability: CDNs use servers across the world, so any increase in demand is dealt with effectively.

A few examples:

Take a look at the likes of butcherbox.com, panmacmillan.com and nexxus.com to see how fast they are.  

What’s next for the JAMstack movement?

Since the term was coined back in 2016, the approach has gone from strength to strength. Static sites are becoming a lot more popular as a way of working, as they offer teams so much flexibility. 

When it comes to delivering content, many of the world’s top companies rely on CDNs to host their websites. Not only do they deliver content to a global audience at speed, but they’re naturally set up to optimize files and images for mobile – which is a huge and ever growing segment of internet traffic.
