Codebold IT Solutions · Redux Development
Redux gets a bad reputation for boilerplate — usually because of how it's set up, not the tool itself. With Redux Toolkit, modern Redux is a fraction of the code it used to be, with a predictable, testable data flow that scales past the point where local state and Context start fighting you.
— What you get
Scroll →
01
Slices, createAsyncThunk, and RTK Query instead of hand-written action types and switch statements — modern Redux, not 2016 Redux.
02
One direction: action → reducer → store → UI. Every state change is traceable, testable, and debuggable with the Redux DevTools.
03
Memoized selectors mean components only re-render when the slice of state they actually use changes.
04
Async logic, logging, and side effects handled through middleware — not scattered across components.
05
Typed state, typed actions, typed selectors — catch a wrong action shape at compile time, not in production.
06
Already have a Redux store built the old way? We migrate it to Redux Toolkit incrementally, without a rewrite.
— How data flows through Redux
01
01
A component dispatches an action — a plain JavaScript object describing what happened, like { type: 'cart/itemAdded', payload: item }. It says what happened, never how the state should change — that separation is what makes Redux state changes traceable and replayable.
02
The reducer takes the current state and the action, and returns a brand new state object — it never mutates the original. A pure function with no side effects, which is exactly what makes it predictable: same state, same action, same result, every single time.
03
The store swaps in the new state and notifies every part of the app that's subscribed to it, but only the specific subscriptions actually affected. This is also the moment Redux DevTools captures a snapshot, so every state change becomes a step you can rewind to.
04
Connected components re-render — but only the ones whose selected slice of state actually changed, thanks to memoized selectors. A cart total updating doesn't re-render the navigation bar, even though both are technically connected to the same store.
— Why Codebold
Building software since 2013.
Not every app needs Redux. We'll tell you honestly if Context or Zustand would serve you better before we write a single reducer.
State management is only half the picture — we build the APIs and backend behind it too, in Node.js or Python.
Fixes, updates, and the next feature are part of the relationship — not a renegotiation every time something needs to change.
— Tech depth
— Good questions
Depends on the app. Redux earns its place when you have complex, cross-cutting state and need serious debugging tools — DevTools, time-travel, middleware. For simpler apps, we'll say so and reach for something lighter instead.
Yes, and usually incrementally — slice by slice, without freezing feature work while it happens.
Yes, with the server/client component split handled correctly so the store only initializes on the client.
Yes — the repository, the code, and everything in it are yours from day one.
We stay on. Fixes, updates, and the next feature are part of the relationship, not a separate negotiation.
Setting up the store and initial slices is usually a few days. The bigger investment is modeling your state shape correctly up front — that's where we spend the real time.
