For so long, the Virtual DOM has been the principal innovation powering React and other modern UI libraries. By abstracting away real DOM mutations, it enabled developers to describe UI in a declarative manner, reducing the need for manual DOM interactions and often improving performance.
However, in 2025, it's time to ask: Is the Virtual DOM still the best approach for all cases?
In this post, I’ll explore why direct DOM manipulation is making a comeback, especially in performance-critical and modern UI scenarios—and why we shouldn’t shy away from it.
🧭 Why Was the Virtual DOM Introduced?
In the early 2010s, as more and more web page started to become web app the frequent DOM manipulation was required and manipulating the DOM directly was slow and expensive.
- Browser engines weren't optimized for frequent, granular updates.
- Layout recalculations and repaints triggered performance bottlenecks.
- Managing state manually across DOM nodes was very difficult and hard-to-maintain codebases.
The Virtual DOM was introduced as a smart layer of abstraction that minimized direct interaction with the DOM, computed diffs efficiently in memory, and batched real DOM updates in a performant way.
It was a very good idea.
🚀 But the Web Has Changed
Lets move ours self today :
- Modern browsers (Chrome, Safari, Firefox, Edge) have significantly optimized their DOM engines.
- Hardware acceleration and fast JavaScript runtimes make DOM manipulation less of a bottleneck.
- Techniques like MutationObserver, requestIdleCallback, and IntersectionObserver provide efficient hooks into the DOM lifecycle.
As a result, many of the performance issues that justified the VDOM in the past are now less relevant—especially for micro-interactions and small-scale updates.
Then the question arises: Do we still need the Virtual DOM for everything?
💡 The Case for Direct DOM Manipulation
With browser advancements, direct DOM manipulation is no longer the performance villain it once was. In fact, for specific use cases, it can offer significant advantages:
- Finer-Grained Control: When you need absolute control over every pixel or specific timing for animations, transitions, or complex canvas interactions, direct DOM manipulation allows for precise adjustments that a VDOM abstraction might obscure or make less efficient.
- Reduced Overhead: Libraries like React and Vue come with a certain bundle size and runtime overhead due to the VDOM reconciliation process. For smaller, highly optimized components or micro-frontends, bypassing the VDOM can lead to significantly smaller JavaScript payloads and faster initial load times.
- Performance-Critical Scenarios: Think about high-frequency updates in games, data visualizations (e.g., D3.js), or real-time dashboards. In these cases, direct manipulation can often outperform VDOM-based updates because you can directly target and update only the necessary elements without the diffing algorithm overhead.
- Simpler Debugging for Specific Changes: When you're directly manipulating the DOM, the link between your code and the visible change is immediate and explicit. This can sometimes simplify debugging for very specific, localized UI updates, as there's no intermediate abstraction layer to consider.
- Leveraging Web Components: The rise of Web Components (Custom Elements, Shadow DOM) encourages a more direct, encapsulated approach to UI development, often without the need for a heavy framework. These components naturally interact with the DOM directly, promoting a modular and performant architecture.
🤔 When Virtual DOM Still Shines
It's crucial to understand that advocating for direct DOM manipulation doesn't mean abandoning the Virtual DOM entirely. It still holds immense value in many scenarios:
- Complex, State-Driven Applications: For large-scale applications with intricate state management and unpredictable UI changes, the declarative nature of VDOM libraries (like React) remains incredibly powerful. Developers can focus on "what" the UI should look like based on state, rather than "how" to update the DOM.
- Developer Experience and Productivity: The declarative paradigm, component-based architecture, and rich ecosystems built around VDOM libraries significantly boost developer productivity, especially for teams working on large projects.
- Cross-Browser Consistency: VDOM libraries abstract away many browser inconsistencies, providing a more uniform development experience and reducing the need for manual browser-specific fixes.
- Server-Side Rendering (SSR) and Hydration: VDOM-based frameworks are well-suited for SSR, which improves initial page load performance and SEO by rendering UI on the server and then "hydrating" it on the client.
⚖️ A Balanced Approach for 2025
In 2025, the conversation isn't about choosing one over the other, but rather understanding when to use which tool.
For highly interactive, performance-critical, or small-scale components, consider direct DOM manipulation, perhaps within the context of Web Components or vanilla JavaScript.
For large, complex applications with rapidly changing data and a need for declarative UI, Virtual DOM-based frameworks continue to be an excellent choice.
Modern web development is about pragmatism. Developers should feel empowered to use the most appropriate tool for the job, combining the strengths of declarative frameworks with the precision and performance benefits of direct DOM manipulation where it makes sense. This hybrid approach allows us to build web experiences that are both powerful and incredibly performant.
The Virtual DOM was a brilliant innovation that solved critical problems of its time. But as the web evolves, so too should our understanding of its best practices. Embracing direct DOM manipulation for specific use cases isn't a step backward; it's a strategic move forward, enabling us to unlock new levels of performance and control in modern web applications.
