Shopify and Magento Optimization: How Version Overlays Can Improve Your E-Commerce Performance and Conversions
September 30, 2025Building a Custom Affiliate Tracking Dashboard: From Data Visualization to Passive Income
September 30, 2025I still remember the frustration of waiting for a WordPress site to rebuild after every content change. Slow, clunky, and locked into a single tech stack. That’s when I decided to go headless—and I haven’t looked back. In this post, I’ll share how I built a fast, flexible CMS using Strapi, Next.js, and the Jamstack. This isn’t just theory: I’ve used this setup in production for clients with thousands of pageviews daily.
Why Headless? Solving the Monolithic CMS Problem
Traditional CMS platforms like WordPress are great for blogs. But they fall short when you need:
- Pages that load in under a second
- Content delivered to apps, smartwatches, or kiosks
- Developers using their preferred tools—not just PHP and jQuery
- Content that works across websites, email, and social channels
<
A headless CMS separates the backend (where content lives) from the frontend (where it’s displayed). Now, your content lives in a simple API. Your frontend—whether it’s React, Vue, or a mobile app—just requests what it needs. This approach powers sites like Nike, Spotify, and Airbnb.
“Headless isn’t just a trend—it’s the architectural foundation for omnichannel content delivery.”
Choosing the Right Headless Platform
I tested three popular options:
- Contentful: SaaS-only, polished UI, great for teams with budget. But it gets expensive as your content grows. I’ve seen projects exceed $10k/month.
- Sanity.io: Flexible with real-time editing. Love the GraphQL-first approach, but the learning curve is steeper. Best for projects with custom editorial needs.
- Strapi: Open-source and self-hosted. I can deploy it anywhere, tweak the code, and avoid per-user licensing fees. For most projects, this is my go-to.
With Strapi, I get:
- No vendor lock-in. Host it on AWS, Vercel, or even a Raspberry Pi.
- Full access to the code. Need to add a custom field? Just edit the model.
- Lower costs. No surprise bills when traffic spikes.
- Plugins for common needs—auth, email, media handling.
Architecture: Jamstack + API-First Content
This system runs on the Jamstack: pre-build pages, then serve them globally via CDNs. Dynamic features (like search or comments) use API calls. Here’s how it works:
1. Strapi as the Content Hub
Strapi is my content admin panel. I create content types using a visual builder or code:
// api/article/models/Article.js
module.exports = {
kind: 'collectionType',
collectionName: 'articles',
info: {
name: 'article',
description: '',
},
options: {
draftAndPublish: true,
},
pluginOptions: {
'content-manager': {
visible: false,
},
'content-type-builder': {
visible: true,
},
},
attributes: {
title: { type: 'string', required: true },
slug: { type: 'uid', targetField: 'title' },
content: { type: 'richtext' },
publish_date: { type: 'date' },
categories: {
type: 'relation',
relation: 'manyToMany',
target: 'api::category.category'
},
featured_image: {
type: 'media',
multiple: false,
required: false,
allowedTypes: ['images'],
},
},
};
Within minutes, I get REST and GraphQL APIs. I prefer GraphQL for its efficiency. This query gets one article with all related data:
query GetArticleBySlug($slug: String!) {
articles(filters: { slug: { eq: $slug } }) {
data {
id
attributes {
title
content
publish_date
categories {
data {
attributes {
name
slug
}
}
}
featured_image {
data {
attributes {
url
alternativeText
}
}
}
}
}
}
}
2. Next.js for Static Site Generation (SSG)
Next.js is my frontend. It pre-renders pages at build time—meaning users get fully built HTML, not blank pages that load content later. The results? Fast loads, great SEO, and no server costs when traffic surges.
During build, I pull content from Strapi:
// pages/articles/[slug].js
export async function getStaticPaths() {
const res = await fetch('http://strapi:1337/api/articles?fields[0]=slug');
const articles = await res.json();
const paths = articles.data.map((article) => ({
params: { slug: article.attributes.slug },
}));
return { paths, fallback: 'blocking' };
}
export async function getStaticProps({ params }) {
const res = await fetch(
`http://strapi:1337/api/articles?filters[slug][$eq]=${params.slug}&populate=*`
);
const article = await res.json();
return {
props: { article },
revalidate: 60,
};
}
The revalidate option enables Incremental Static Regeneration. If a user requests a page that’s 60+ seconds old, Next.js rebuilds it in the background. Fresh content, no full site rebuilds.
3. Gatsby as an Alternative for Data-Heavy Sites
For content-rich sites (like portfolios or product catalogs), I use Gatsby. It’s amazing for:
- Complex data relationships (e.g., “Show all articles by authors with over 5 posts”)
- Image resizing and WebP conversion
- Adding SEO tags, analytics, and PWA support with simple plugins
The gatsby-source-strapi plugin connects my content:
// gatsby-config.js
module.exports = {
plugins: [
{
resolve: 'gatsby-source-strapi',
options: {
apiURL: process.env.STRAPI_API_URL,
collectionTypes: ['article', 'category'],
singleTypes: ['global', 'homepage'],
queryLimit: 1000,
},
},
],
};
API-First Content: Designing for Reusability
Here’s where headless shines: content can live everywhere. When I design a content model, I ask: “Where will this appear?” The answer is often: “Everywhere.”
- Modular: Break content into blocks (Strapi’s dynamic zones). One article might have a hero, three text sections, and a CTA banner.
- Structured: Use clear relationships (e.g., article → category). This makes filtering and navigation easier.
- Multi-language: Support translations from day one. Strapi handles this with a few clicks.
Example: Dynamic Content Blocks
Instead of dumping everything into a single rich text field, I split it into components:
- Hero section (with headline and image)
- Text block (with formatting options)
- Image gallery (responsive grid)
- CTA banner (button and text)
In Strapi, I use a dynamic zone:
attributes: {
content: {
type: 'dynamiczone',
components: ['blocks.hero', 'blocks.text', 'blocks.gallery'],
},
}
On the frontend, each block becomes a React component:
{article.attributes.content.map((block) => {
switch (block.__component) {
case 'blocks.hero':
return
case 'blocks.text':
return
// ...
}
})}
This approach means editors can build layouts visually—no code needed.
Performance Optimization: From Build to Delivery
Speed isn’t optional. My goal: load time under 1 second, even on mobile. Here’s how I hit it:
1. CDN + Edge Caching
I deploy Next.js to Vercel. Their global CDN (called the Edge Network) serves pages from the closest location to each user. This cuts latency dramatically.
2. Image Optimization
Strapi’s media library works with Cloudinary or Imgix. I automatically generate:
- Responsive images (different sizes for phones vs. desktops)
- WebP versions (25% smaller than JPEG)
- Lazy loading (images load as you scroll)
3. Cache-Control Headers
For static pages, I set long cache times:
Cache-Control: public, max-age=31536000, immutable
The immutable flag tells browsers: “This page won’t change until the URL does.” For dynamic content (like live comments), I use client-side JavaScript or edge functions.
Deployment: CI/CD Pipeline
I automate everything with GitHub Actions:
- When I push changes to Strapi’s
mainbranch, it deploys to AWS ECS. - When an editor publishes new content in Strapi, it sends a webhook to Vercel. Vercel rebuilds the affected pages.
- Every pull request gets a preview deployment. I can test changes live before they go to production.
This setup means content goes live in minutes—not hours.
Conclusion: The Headless Advantage
This stack—Strapi, Next.js, and Jamstack—has become my default for new projects. Here’s why:
- Strapi gives me control, flexibility, and low costs. No per-user fees, no vendor lock-in.
- Jamstack delivers unmatched speed and reliability. Static pages on a CDN are fast, secure, and cheap to run.
- Dynamic content blocks make editors happy. They can build rich layouts without touching code.
- ISR + CDN scales effortlessly. I’ve handled traffic spikes from 100 to 100,000 visits/day with no extra work.
For CTOs: This reduces server costs and simplifies your tech stack. For freelancers: It’s a valuable skill to offer clients. For startups: It’s the foundation investors expect for modern web apps.
The future isn’t just headless—it’s fast, flexible, and API-first. Now, you have the tools to build it.
