In the last month, I gradually migrated several projects from server-rendered Nuxt.js applications to statically generated websites, powered by Nuxt.js too, as already hinted in my previous article.
It all started with my portfolio which consists of one larger page and two pages for privacy and legal notice. All three pages have actually no dynamic data involved (as you can see in the source code). The text, the images and everything else are completely hardcoded. Last year, the page was served from one of my Virtual Private Servers (VPS) by always running Node.js server. The only purpose of it was to respond with the same content again and again.
At some point, I thought that there must be a better way, so I started using Nuxt.js as Static Site Generator. Now no Node server was involved anymore, only plain HTML files that were served by the VPS. Not too bad, but… why do I need a server at all for managing a simple static page? Correct, I do not! But more about that in a second.

- Netlify features I’m missing and why I still use Cloudflare
Last but not least: All page interactions, like submitting forms or retrieving more content, are handled through APIs that are called via HTTP(S). Most of the time, microservice-based APIs or serverless functions are used in combination with the JAMstack approach.
Further information about JAMstack can be found on the official JAMstack.org page.
Okay, so far so good. Now you might have another question: “Why should I go for JAMstack?”. There are four main reasons in my opinion.
As mentioned briefly in the introduction, you don’t need a server anymore to host your website. Instead, you can use platforms like GitHub Pages or Netlify and let them grapple with the underlying infrastructure and maintenance. No more server management!
It gets even better: No more difficult deploys as well. As the markup will be pre-built you could set up webhooks to re-build your website when data changes, e.g. when you update a blog post.
Guess how often websites are being targeted by hackers? A Forbes article from 2013 shows that back then, more than 30,000 Wordpress pages were hacked every day, which is an insane number. With JAMstack, you decrease your attack surfaces a lot because your site isn’t served by a server anymore. Sure, you still have the APIs as possible targets but as they are decoupled and isolated from each other, at least most of the time, it’ll give the attacker a harder time, too.
No system is 100% secure but with JAMstack, things get less attractive for potential adversaries by default. And even if you are using a content management system like Wordpress through an API to populate your upcoming website: Ideally* you wouldn’t expose your API at all because you could prefetch all the data needed and persist them as JSON files.
Also, because your page is re-built every time you change something, you can always invalidate the cache directly. This is a huge win because cache-invalidation is actually a hard thing as some of you probably experienced already.
Last but not least, don’t forget one thing: Static HTML is faster than, or at least as fast as, dynamic HTML returned from your server.
JAMstack also means cutting costs in most of the cases. No server means no server fees and also no server management needed. If you host your page, Netlify, this is free for a 100GB bandwidth soft limit per month. Also you can possibly reduce the resources needed for your APIs by transforming them into serverless functions.
Most of you might know Nuxt.js as “the framework on top of Vue that can do server-side rendering”. For those of you who don’t know Nuxt.js at all yet, make sure to check out the official website. But Nuxt.js is way more than that.
Sure, server-side rendering (SSR), is one part of it, but being a Static Site Generator is another. That means, it will take a “snapshot” of your pages and export them as HTML. I often describe it as the best of both worlds between a traditional single page application and a server-side-rendered project. While keeping the search engine optimization benefits provided by the HTML, you don’t need a Nuxt.js instance running all the time.
To generate the page, all you have to do is to run
nuxt generate. A
dist folder will appear with the HTML inside.
Before writing about how I moved three of my websites over to Netlify and JAMstack and what I experienced during that process, I want to give a rough overview of what Netlify actually is, what they are doing and why I chose them.
Netlify is an all-in-one platform for hosting static websites and a pioneer of the JAMstack tech. With Netlify, you can deploy your page in under a minute. No joke! They provide automatic deployments after commits to your Git repository or via webhooks, deploy previews for Pull Requests, form handling, serverless functions, A/B testing through different branches, one-click SSL, a CDN, a managed DNS and that all with a generous free tier.
My portfolio page was the first one I moved to JAMstack, as said in the beginning, and moving it to Netlify was a
breeze. I switched to the
nuxt generate command in my application to export my current Nuxt.js page as HTML
files, connected my GitHub repository to Netlify, set up the correct build command and hit deploy. ? Tada, the page had
been deployed! Now all I had left to do was pointing the domain to the correct spot and the new JAMstack-based page
was up and running.
With my donation page it was not that easy because I had to think about how to manage the “donate” feature (using the Stripe API). Setting up a server just for that one function would be possible but a waste of resources. Why not giving Netlify Functions, a convenient wrapper around AWS Lambdas, a shot? As the code for the donation logic itself was always kind of “isolated”, transforming it into a serverless function was no big deal. After the “standard” procedure, converting the function, changing the URLs and testing it, thanks.lichter.io was ready as well.
The last experience report is about this blog. When I wrote the first lines of code for it I already puzzled my head over which approach I should take. Markdown files and a static blog or powered by an API? I decided for the latter because I wanted to have the option for more dynamics, like showing a “Trending Posts” section based on Google Analytics data. I built the API with Laravel (yes, PHP) and the frontend with Nuxt.js as you could already guess. The blog ran on server-side rendered for a long time because the Markdown coming from the API had to be parsed “on the fly”.
But the more I thought about in the last weeks, the more I was convinced that a JAMstack approach would work here as
well. So I started to fiddle around. The transition took a bit longer than for the other pages but that was because of
the size of the project and the dynamic data. What I did, in the end, was to set up webhooks that triggered a page
rebuild when changing one of my articles or updating trending posts. Furthermore, I had to change my
pagination from a query string based approach (
?page=2) to a more URL-based approach (
/page/2) as generated pages
can’t take query strings into account very well. Besides that, there were no complications.
I haven’t ported all my projects to the JAMstack approach. Some of them, including Brotli.pro, are relying too much on dynamic data and their near-real-time availability but still need the SEO benefits. In case you have a page where data could change every few seconds (or even faster) and where you need good SEO, I would not suggest going for JAMstack for that particular project. This does depend heavily on the situation and use case though.
Though I switched over to Netlify, I still use Cloudflare in front of most of my pages. The Netlify CDN is excellent but Cloudflare provides a few features that Netlify doesn’t have at the moment and that I have to rely on.
Speaking of Brotli.pro, Netlify does not support the Brotli encoding yet. This feature is planned and will come to Netlify in the future but there is no ETA for it yet.
PS: If you don’t know what Brotli is, check out the info page
Update: Netlify Analytics is available since a few months as a paid feature.
While more and more people are using anti-tracking measurements and ad blockers, it’s hard to get a unique visitors number close to reality when I’d only rely on client-side analytics. Cloudflare provides them and also gives more info regarding the country of the user. Whether these numbers are “more accurate” or including bots and crawlers, I’d love to see some analytics coming for Netlify.
While this is a thing that affects the majority of the CDNs right now, it’s still something I want to list. If you did not know yet, HTTP2 is essentially broken on many CDNs, including Netlify (to the time of writing). As this issue is a bit more complex, I won’t go into detail here. More information can be found on this repository
JAMstack, especially in combination with a custom API or a headless CMS** is terrific. Easy deployments, no servers to worry about and a free performance boost. Thanks to Netlify for investing time and resources in this whole architecture and style. Netlify itself as a platform is steadily growing. The current features are solid and make the whole process of getting up and running with JAMstack very friction-less. A few things are missing here and there but they are mostly related to convenience or are planned in the future.
If you are building your next project, be it a side project or something for a client, you should consider taking this way. And if you are looking for a neat Static Site Generator, you know my choice now ?
Thanks for reading!
