Ditching React for HTMX Slashed Our Frontend Codebase by Two Thirds
For the past decade, the tech industry has operated under a collective hallucination: the idea that every web application, no matter how simple, requires a complex JavaScript framework to be "modern." We fell in love with the component lifecycle, obsessed over virtual DOM diffing, and buried ourselves in the labyrinth of state management. But as our bundles grew and our build times skyrocketed, a quiet revolution began. By ditching React for HTMX, our team managed to slash our frontend codebase by a staggering 66%, trading thousands of lines of convoluted JavaScript for clean, declarative HTML.
This wasn't just a refactor; it was a fundamental shift in how we perceive the relationship between the server and the browser. If you are currently drowning in "JavaScript fatigue," the solution might not be a newer framework, but rather a return to the Hypermedia Architecture that built the web.
The Hidden Cost of Modern Frontend Complexity
The "React Tax" is a very real phenomenon. When you build a standard Single Page Application (SPA), you aren't just writing a UI; you are building a distributed system. You have a backend that speaks JSON and a frontend that must translate that JSON into DOM elements. This creates a redundancy trap where you define your data models in your database, redefine them in your API layer, and redefine them once more as TypeScript interfaces in your React components.
In our previous architecture, adding a simple "Like" button required:
Creating a state variable with useState.
Writing an onClick handler.
Triggering a fetch request.
Manually updating the local state to reflect the change.
Handling loading and error states explicitly.
By moving away from this paradigm, we eliminated the need for complex state synchronization and the massive overhead of client-side routing.
What is HTMX and Why is it Disrupting the Status Quo?
HTMX is a library that allows you to access modern browser features directly from HTML, rather than using JavaScript. It extends the core philosophy of the web—Hypermedia as the Engine of Application State (HATEOAS)—by allowing any element to trigger an HTTP request and swap its content with the server's response.
Instead of the server sending raw JSON that the client must then parse and render, the server sends HTML fragments. This simple change removes the need for a client-side rendering engine entirely.
The Power of Locality of Behavior (LoB)
One of the greatest benefits we discovered is Locality of Behavior. In React, the logic for a single feature is often scattered across multiple files: a component file, a CSS module, a Redux slice, and an API service folder. With HTMX, the behavior is defined right where the element lives.

</button>
How We Deleted 10,000+ Lines of Code
When we audited our codebase during the migration, we realized that two-thirds of our React code was dedicated to things that had nothing to do with the user's actual experience. We were writing "code to manage code."
1. Eliminating State Management Libraries
By ditching React, we completely removed Redux and its associated boilerplate. Since the server now holds the "source of truth" and simply sends the updated HTML representation of that state, the client no longer needs to maintain a complex, synchronized cache of the database.
2. Radical Simplification of Tooling
Our package.json shrank overnight. We deleted Webpack configurations, Babel plugins, and dozens of specialized React hooks. We replaced a 300MB node_modules folder with a single script tag. This didn't just reduce our codebase; it accelerated our CI/CD pipelines by 400%.
3. Unified Validation Logic
In the React world, you often have to write validation logic twice: once on the frontend for immediate feedback and once on the backend for security. With HTMX, we perform validation on the server and return the invalidated form fragment with error messages already rendered. This ensures a "Single Source of Truth" for business logic.
Technical Comparison: React vs. HTMX
To illustrate the dramatic reduction in complexity, let's look at a common UI pattern: an "Inline Edit" feature.
<divhx-get="/contact/1/edit"hx-trigger="click"hx-swap="outerHTML"> John Doe
</div>
The server simply returns the input field when clicked. When the input is submitted, the server returns the updated text. The frontend logic is zero lines of JavaScript.
Performance Gains Beyond the Codebase
Beyond the developer experience, the performance metrics were undeniable. By ditching React for HTMX, we observed:
Reduced Time to Interactive (TTI): Since there is no massive JavaScript bundle to parse and execute, the page becomes interactive almost instantly.
Lower Memory Usage: Browsers no longer have to maintain a complex Virtual DOM tree in memory.
Improved SEO: Because the initial payload is fully rendered HTML, search engine crawlers have no trouble indexing the content without relying on complex headless browser rendering.
Is HTMX the Right Choice for Your Project?
While our experience was transformative, HTMX is not a silver bullet. It is essential to understand where it excels and where it might fall short.
When to Stick with React
If you are building a highly offline-capable application or a tool with high-frequency UI updates (like a Google Docs clone or a video editor), the Single Page Application model is still superior. These apps require a thick client to manage complex, local-first interactions.
When to Switch to HTMX
If your application is primarily CRUD-based (Create, Read, Update, Delete)—which describes 90% of internal tools, dashboards, and B2B SaaS platforms—HTMX is likely a better fit. It allows you to move faster, write less code, and focus on your product rather than your framework.
Conclusion: Embracing the Future by Reclaiming the Past
Our journey of ditching React for HTMX taught us that more code is rarely the answer to better software. By removing the unnecessary abstraction layers of the modern JS stack, we regained our productivity and created a more maintainable, performant product. We didn't just slash our codebase; we simplified our cognitive load.
If you are tired of the constant churn of frontend frameworks, it’s time to take a serious look at HTMX. Start small—replace one complex React component with an HTMX-powered server route. You might find that the best way to move forward is to embrace the simplicity the web was always meant to have.
