Redux – Overview ”; Previous Next Redux is a predictable state container for JavaScript apps. As the application grows, it becomes difficult to keep it organized and maintain data flow. Redux solves this problem by managing application’s state with a single global object called Store. Redux fundamental principles help in maintaining consistency throughout your application, which makes debugging and testing easier. More importantly, it gives you live code editing combined with a time-travelling debugger. It is flexible to go with any view layer such as React, Angular, Vue, etc. Principles of Redux Predictability of Redux is determined by three most important principles as given below − Single Source of Truth The state of your whole application is stored in an object tree within a single store. As whole application state is stored in a single tree, it makes debugging easy, and development faster. State is Read-only The only way to change the state is to emit an action, an object describing what happened. This means nobody can directly change the state of your application. Changes are made with pure functions To specify how the state tree is transformed by actions, you write pure reducers. A reducer is a central place where state modification takes place. Reducer is a function which takes state and action as arguments, and returns a newly updated state. Print Page Previous Next Advertisements ”;

Redux – Installation ”; Previous Next Before installing Redux, we have to install Nodejs and NPM. Below are the instructions that will help you install it. You can skip these steps if you already have Nodejs and NPM installed in your device. Visit https://nodejs.org/ and install the package file. Run the installer, follow the instructions and accept the license agreement. Restart your device to run it. You can check successful installation by opening the command prompt and type node -v. This will show you the latest version of Node in your system. To check if npm is installed successfully, you can type npm –v which returns you the latest npm version. To install redux, you can follow the below steps − Run the following command in your command prompt to install Redux. npm install –save redux To use Redux with react application, you need to install an additional dependency as follows − npm install –save react-redux To install developer tools for Redux, you need to install the following as dependency − Run the below command in your command prompt to install Redux dev-tools. npm install –save-dev redux-devtools If you do not want to install Redux dev tools and integrate it into your project, you can install Redux DevTools Extension for Chrome and Firefox.
