When I was starting out in looking for alternatives to migrate my blog as it was previously in Wix.

I was considering using WordPress due to its support by many hosting providers and affordable prices that allows me to host my blog.

I stumble across youtube videos or articles, talking about static site generator.

Which summarises as security, affordability, speed and time for maintenance for websites build using it.

What is JAM Stack?

You might be wondering, why am I talking about static site generators instead of talking about JAM stack? Well to me it's actually one and the same.

Let's break down what does JAM mean. JAM stands for the first J for Javascript, A stands for API and M is Markup.


J for Javascript

For the javascript in JAM, it could be the big 3 in front-end web development.

For most web developers that are Vue, React and Angular which has their own static side generators to present their data.

This does not mean other static site generators could not be used for the J portion of the JAM stack which Hugo, Jekyll, Next does come to mind for it.

A for API

API for JAM stack is usually used to provide a specific functionality like content delivery, email, payment other related services for a website.

Therefore JAM stack could be used for a variety of websites like e-commences besides just company websites or blogs.


Markup is the bread and butter used to create content for static sites that are served as an API endpoint.

Since they are usually converted into HTML, CSS or Javascript through the use of static site generators.

The time it takes for a website to load is lighting fast.

Advantages of JAM stack


Ease of Development and Deployment

Due to the ecosystem and services by a wide variety of service providers.

The development and deployment of JAM stack based websites can be relatively painless and could be scaled with ease.

Take for example my personal blog, I use netlify as a hosting and deployment service for static sites.

The building process starts by whenever I push my code changes to my Gitlab repository.

Then it pulls content from Contentful endpoint and various other services endpoint.

Which combined with the code changes that I pushed is converted into the various static file through Gatsby.

These newly generated static files are then deployed on Netlify as a website that with CDN, HTTPS and form submission provided for free by Netlify.

Content Creation

Content is usually in a markdown file format but could be other file formats depending on your static site generator.

It is relatively easy to learn even for a person who is not a developer to manage and create content for markdown files.

These could be in gitLab or Contentful, who provides an API endpoint that your static site generator could pull content directly.

Lastly by no means that content should only be in markdown.

In fact, content could be pulled from CMS like WordPress & Contentful or through external API sources which display data.

Cost in Maintenance & Managing the Website

Usually, the cost associated with maintaining a website includes the hosting, updating of versions and content update.

It is really affordable or free to host a static site with a bunch of hosting providers ranging from Netlify that I use myself, AWS, Github or GitLab.

Unlike WordPress, there is a need to regularly update due to security reasons.

A static site website removes the need to update your website by using static files it is hard for any hackers.

To hack your website by taking advantage of the security vulnerability founded in your static files.



To date, there are more and more websites that are deployed with static sites due to the above advantages that I had listed out.

One of the notable websites that use the static sites is FreeCodeCamp a popular online platform for developer to have a Coding Bootcamp education for free.

It is actually funny as during that point of the time I didn't know about it.

Despite, I had made changes to the guides during the Hacktoberfest for FreeCodeCamp in markdown.

It was when I was reading Quincy Larson's the founder of FreeCodeCamp first article on the Dev Community.

That talks about why they had migrated their website to be static sites.

I would consider anyone who is interested in JAM stack to take a look at his article to understand further why did they migrate their website to JAM stack.
