Redux was inspired by Flux but it omitted the unnecessary complexity: it does not have Dispatcher concept, has a single Store and the Action objects is received and handled directly by Store in the Redux. The thunk can be used to delay the dispatch of an action, or to dispatch only if a certain condition is met. Redux is an open-source JavaScript library which was first introduced in 2015 by Dan Abramov and Andrew Clark in 2015.

How to use useReducer + Context in React. Redux Thunk middleware allows you to write action creators that return a function instead of an action. That’s how ContextAPI came to play.Ĭontext API provides a simple way to share data between components without the need of passing props across all levels of you app tree.

But we also know that this can generate a bunch of problems, such as bugs, verbose code, some spaghetti code that nobody wants go change. Since the early days of React, we know that the data sharing between components is done by top-down (parent to child).

const dispatch useDispatch() Our action. See the React Redux documentation for details. Redux useDispatch React Redux Redux useDispatch useDispatch is a hook of react-redux which allows us to dispatch our actions without connecting our component with connect method. If you need a more specific type for the dispatch function when dispatching, you may specify the type of the returned dispatch function, or create a custom-typed version of useSelector. So I will skip any other explanation about what is Redux, flux, actions, action types, selectors, what is the meaning of life, etc… By default, the React Redux useDispatch hook does not contain any types that take middlewares into account. Then Redux applies this “action” in its state, returning a new state with the desired change.īut as I said before, you might know that already.

The action must have a type property as shown above.

The dispatch function takes an object as a parameter which is known as an action.
