I am started learn NodeJS MongoDB. Before that, I studied React Redux. As I understand MongoDB replaces Redux or is it not? If not, what data should be stored in Redux and what data in MongoDB?

CodePudding user response：

Redux is state management which is used to transfer data between components, But this data is lost when the tab of browser closes or refreshes.

redux-saga can be used to store data in the user's browser, which stores the redox data in the browser's local storage.

But MongoDB is a server-side database for storing data on the server side permanently. To get information in Front-End, a request must be sent to the server using the API and the Back-End data must be sent to the front-end or the user. In general, information including user information and user login information, etc. should be stored in the database.

Redux is an state manager normally used in React Applications to share the application state globally across component tree. The MongoDB is a NoSQL database manager used to store your application data. i think they are not equivalent.
