If you have a background in Javascript, you may be knowledgeable about Redux and Context API. And you've likely come across a slew of blogs debating which is superior: Redux vs. Context API. Unless I'm mistaken, I assumed the same thing until I realized it wasn't!

After reading a couple of blogs, I deduced the intent of both toolkits and how they vary from one another. If you're not informed, don't feel anxious; this tutorial will walk you through the use cases of both tools using a simple demo example. In this section, we will build and discuss an app using both approaches.

Redux: Introduction and Building Blocks As Documented -

Redux is an architectural style and library for handling and upgrading app data through "actions." It acts as a centralized store for the state that must be used throughout your app, with guidelines ensuring that you can revise the state in a consistent pattern.

The records state unequivocally that redux is for "controlling state" and comprehending how upgraded the state.

Redux is primarily used to handle React apps in a centralized location from which you can access the state from anywhere in the application. The Redux idea is based on Flux architectural style, but it is not limited to React apps; there are configurations in other technologies. However, Redux is especially well-integrated with React.

It is primarily composed of four building sections:

1. Reducer: All those are features that take state as well as actions as reasoning. In flip instances, it includes "action.type," which comes back the changed value. It may acknowledge the payload if desired (generally created in a separate file known as reducers.js)

2. Store: A store is a repository for all information. You can give this to the supplier.

3. Provider: A React element that acknowledges the argument store (usually created in index.js)

4. Actions: Tasks that provide action type and payload to the scheduler, who then calls the appropriate reducer

Context API: Overview and Components

As per the documentation of React, The context API, it is claimed, "provides a solution for data with the help of an element without having to pass credit independently at each stage."

Data is typically passed leading via props in a typical React application, but this can be inconvenient in certain props needed by many elements within an app. Context allows users to share qualities like these between elements without expressly passing a prop through each level in the system.

Example of a Redux and Context API

The following example is focused on a Counter. It will start with a value of 0 and will have 2 options to increase and decrease the value.

There will be three child components within the main parent counter component-

To conclude, this was the Introduction and Use Cases of Redux and Context API with React Native App; if you want to learn more in detail about the implementation and comparison, you can click on the link mentioned above. Furthermore, try implementing both strategies and tinkering with the code to delve deeper. We have a React Native Tutorials page with step-by-step instructions and the github source for more React Native tutorials.
