However, I think most of the time a lot of us like to default to throwing things into the global store to avoid prop drilling. However, redux might be a good choice for rich applications, where the front-end is practically a full-featured desktop application, and the back-end serves as mere storage for BLOBs (with metadata). Redux is a very wrong tool for any front-end (dumb client/interface) of information systems, where the back-end is the single source of truth – the centralized state. Note that this doesn’t even begin to handle refetching, caching, and invalidation.
You might want to check it out, and later pick what suits you the most. The downside is a little bit of indirection, but we believe it’s worth it in real applications. AWS IoT Greengrass is software that extends cloud capabilities to local devices. This enables devices to collect and analyze data closer to the source of information, react autonomously why redux to local events, and communicate securely with each other on local networks. Local devices can also communicate securely with AWS IoT Core and export IoT data to the AWS Cloud. AWS IoT Greengrass developers can use AWS Lambda functions and prebuilt connectors to create serverless applications that are deployed to devices for local execution.

Now the reducer will take your action, it will perform its job and it will ensure that you get your money. Sending off the action to the reducer is called dispatching an action. In contrast to Flux, Redux only has a single store that holds no logic by itself. Actions are dispatched and handled directly by the store, eliminating the need for a standalone dispatcher. In turn, the store passes the actions to state-changing functions called reducers, a new type of actor added by Redux.
Especially with the latest useReducer hook, you can absolutely do this with Context without using Redux. But at that stage you’re basically re-inventing Redux, so you really should ask yourself what the benefits of that are vs. simply using Redux and build your abstractions on top of that where needed. Again, it obviously depends on what your state actually looks like. If it’s very simple, only covering one or two context providers, doing the same with React Context doesn’t add much if any overhead.
But… you should use redux-saga 🙂
No one is going to give you money if you just roam around here and there. If you want to update the state of your Redux (like you do with setState in React) you need to let Redux know about your action. Just like you follow a process to withdraw money from your bank, Redux also follows a process to change/update the state of your application. Well, at first these 9 words give you the feeling of 90 incomplete sentences where you don’t get anything. Well, the documentation has explanatory stuff when you start reading it.
We fetch data, add it to our store with a reducer/action, and refetch it periodically to make sure it’s up to date. We are making Redux do too much and using it as a catch-all solution to our problems. Redux was a revolutionary technology in the React ecosystem. It enabled us to have a global store with immutable data and fixed the issue of prop-drilling in our component tree. For sharing immutable data across an application, it continues to be an excellent tool that scales really well.
A pure function returns the same output for the same input. You can use reducers to generate a new application state. https://deveducation.com/ Redux creates a single ‘data store’ for managing state that can be accessed throughout the entire application.
- An e-commerce website will have several components like the cart component, user profile component, previously viewed section component, and so on.
- We will talk about changing/updating the state later in this blog.
- Anyone trying to tell you that you have to use a specific solution, without knowing your requirements and the specific problems you’re hoping to solve, is not acting in your best interest.
- Another interesting approach is Redux Saga which lets you define long-running daemons (“sagas”) that take actions as they come, and transform or perform requests before outputting actions.

Redux is strict about how code should be organized, which makes it easier for someone with knowledge of Redux to understand the structure of any Redux application. This generally makes it easier to maintain, and also helps you segregate your business logic from your component tree. For large scale apps, it’s critical to keep your app more predictable and maintainable. Redux allows developers to intercept all actions dispatched from components before they are passed to the reducer function.
