What is Redux used for?
Redux is used mostly for application state management.
To summarize it, Redux maintains the state of an entire application in a single immutable state tree (object), which can’t be changed directly.
When something changes, a new object is created (using actions and reducers)..
When should I use Redux?
In general, use Redux when you have reasonable amounts of data changing over time, you need a single source of truth, and you find that approaches like keeping everything in a top-level React component’s state are no longer sufficient. However, it’s also important to understand that using Redux comes with tradeoffs.
Is Redux necessary for react?
You don’t always need Redux for every app, or every component. If your app consists of a single view, doesn’t save or load state, and has no asynchronous I/O, I can’t think of a good reason to add the complexity of Redux. Likewise, if your component: Doesn’t use the network.
Does Facebook use Redux?
Dan Abramov on Twitter: “Actually Facebook doesn’t use Redux “at scale”, it uses Flux :-)… ”
Is Redux server side?
On the client side, a new Redux store will be created and initialized with the state provided from the server. Redux’s only job on the server side is to provide the initial state of our app.
What problem does Redux solve?
The reason Redux is useful is that it solves a problem. And no, the problem it solves is not “state management.” That’s super vague. Heck, React already does state management. Redux does help manage state, but that’s not the problem it solves.
Is Redux frontend or backend?
Redux is the Pivotal Frontend Innovation.
Why is redux bad?
What I Hate About Redux. If you use redux to develop your application, even small changes in functionality require you to write excessive amounts of code. This goes against the direct-mapping principle, which states that small functional changes should result in small code changes.
What exactly is redux?
Is Redux a CQRS?
(Fun fact: Redux is actually based in part on CQRS and event sourcing.) Commands can be written so that they dispatch events when fired. Then the events speak to the store (database) and update the state.
Is Redux difficult?
Yes, in some ways Redux is more complicated. It adds a couple levels of indirection to the process of updating state, there’s a bunch of new terms, and it requires thinking about your code in some ways that are probably very new and different for you. So yes, many people do find it confusing to start with.
Why you don’t need redux?
Applications that perform mainly simple actions and do not require server-side rendering probably don’t need Redux; their actions can be handled at the component level. Either way, Redux is an awesome tool, and I think you should check it out, especially if you’re working with React.
