TanStack Store Slashed Our Redux Codebase by 60 Percent
For years, Redux has been the undisputed heavyweight champion of state management in the React ecosystem. However, as applications scale, the "Redux tax"—the inevitable mountain of boilerplate, action types, and complex middleware—often becomes a bottleneck for velocity. In our recent architectural overhaul, we discovered that TanStack Store slashed our Redux codebase by 60 percent, fundamentally changing how we approach global state without sacrificing the predictability we relied on.
The shift away from heavy state management libraries isn't just about following trends; it is about efficiency. When we audited our legacy Redux Toolkit implementation, we found that nearly two-thirds of our code existed solely to satisfy the library's structural requirements rather than delivering actual business logic. By migrating to TanStack Store, we eliminated the friction of traditional flux architectures and embraced a leaner, type-safe alternative.
The Burden of Legacy State Management
Redux was designed in an era when we needed a strict, centralized "source of truth" to manage complex UI states. While it solved the problem of "prop drilling," it introduced a high cognitive load. To update a single boolean value, developers often had to touch four different files: the constant definitions, the action creators, the reducer logic, and the selector.
Even with the introduction of Redux Toolkit (RTK), which significantly improved the developer experience, the underlying philosophy remained the same. You still had to manage "slices," deal with the dispatch pattern, and navigate a complex web of middleware for side effects. For our team, this resulted in a repository where state management logic often overshadowed the actual feature code.
What is TanStack Store?

Created by Tanner Linsley—the mind behind TanStack Query and TanStack Table—TanStack Store is a framework-agnostic, high-performance state management library. It is designed to be incredibly lightweight, weighing in at less than 1kb gzipped.
Unlike Redux, which enforces a specific "action-reducer" flow, TanStack Store provides a simple, reactive core. It allows you to create a store, subscribe to changes, and update state with minimal friction. Most importantly, it offers first-class TypeScript support, ensuring that your state remains type-safe without the need for manual interface declarations at every step of the data flow.
The 60 Percent Reduction: A Deep Dive into the Numbers
When we say TanStack Store slashed our Redux codebase by 60 percent, we aren't just talking about a few lines of code. We are talking about the complete removal of entire architectural layers that were no longer necessary.
Eliminating the Action-Reducer Cycle
In Redux, every state change requires an action to be dispatched and a reducer to catch it. This creates a "ping-pong" effect in the codebase. TanStack Store allows for direct state mutations (via functional updates) that are still tracked and reactive. By moving to a model where the store is updated directly by the components or services that own the logic, we deleted over 200 "action type" constants and 150 "reducer cases."
Streamlined Type Inference
One of the most significant contributors to our code reduction was automatic type inference. In our Redux setup, we had to manually type every state slice, every action payload, and every selector return value. TanStack Store's API is built so that the state's shape is inferred directly from the initial value. This eliminated the need for redundant TypeScript interfaces that previously cluttered our types.ts files.
Technical Comparison: Redux vs. TanStack Store
To understand how we achieved such a drastic reduction, let’s look at a standard counter implementation.
In the TanStack example, we don't need a "slice" wrapper, we don't need to export separate action creators, and we don't need to configure a global provider if we choose to use the store as a standalone module. The logic is co-located and significantly easier to read.
Performance and Developer Experience (DX)
Beyond the raw line count, the developer experience with TanStack Store is vastly superior for modern agile teams. Because the library is framework-agnostic, we were able to share state logic between our React web app and a small Node.js utility script without any modification.
Granular Reactivity
TanStack Store uses a fine-grained subscription model. When a piece of state changes, only the components specifically "listening" to that slice of data re-render. This is achieved through the useStore hook, which accepts a selector function:
This ensures that our application remains performant even as the global store grows, preventing the "unnecessary re-render" pitfalls common in poorly optimized Redux applications.
Immutability Made Simple
While Redux relies on Immer under the hood to handle immutability, TanStack Store keeps things transparent. You can use simple spread operators or integrate your own immutability library if preferred. This lack of "magic" makes debugging much simpler—what you see in the setState function is exactly what happens to the state object.
Is It Time to Migrate?
If your team is currently struggling with a bloated Redux implementation, the prospect of migration might seem daunting. However, the beauty of TanStack Store is that it can co-exist with Redux. We didn't rewrite our entire app overnight. We started by migrating our "UI State" (modals, sidebar toggles, form drafts) to TanStack Store while leaving our complex "Server State" to TanStack Query.
You should consider migrating if:
Your store/ folder is the largest part of your src directory.
New developers take more than a day to understand your state flow.
You are heavily invested in TypeScript and want better inference.
You are building a multi-framework project (e.g., React and Vue).
Conclusion: A Leaner Future for State Management
The era of "Redux by default" is coming to an end. By embracing specialized tools like TanStack Store for global UI state and TanStack Query for server-side data, we have entered a period where our codebases can be smaller, faster, and more maintainable.
The fact that TanStack Store slashed our Redux codebase by 60 percent is a testament to the power of simplicity. We traded complex abstractions for direct, type-safe state manipulation, and the result is a more productive engineering team and a snappier user experience.
