DAY 10 of #20DaysOfReact
Topic Covered :
- Introduction to Redux
What is Redux?
Redux is an open-source JavaScript library commonly used in front-end web development for managing the state of an application. It is often used in conjunction with popular JavaScript frameworks like React, Angular, and Vue, but it can also be used with other libraries and frameworks.
Redux was created to address the challenge of managing complex application states and their transitions in a predictable and maintainable way. It enforces a unidirectional data flow, which helps in debugging and understanding how data changes over time.
Key concepts and components of Redux:
- Store: Think of it as a big container that holds all the important data for your app. It's like a storage room where you keep everything you need.
- Actions: Actions are like requests or instructions that you send to the storage room (the store). For example, you might send an action to add something to your storage room or take something out.
- Reducers: These are like the workers in the storage room who follow the instructions (actions) and make changes in the storage room. They decide how the storage room should be organized based on the actions.
- Dispatch: Dispatching an action is like telling the workers to follow a specific set of instructions. You say, "Hey, workers, here's what I want you to do," and they do it.
- Selectors: These are like special tools you use to get exactly what you need from the storage room. Instead of searching through the entire room, you use a tool to find the specific item you want.
- Middleware: Middleware is like a security guard or a manager. It can do things before or after an action is completed. For example, it can check if the action is allowed or perform additional tasks.
React Redux includes a <Provider /> component, which makes the Redux store available to the rest of your app. Also, it provides a pair of custom React hooks that allow your React components to interact with the Redux store.
To use React Redux with your React app, install it as a dependency.
npm install react-redux
That's it for Day 10. Tomorrow we will dive into how to fetch data from APIs. Thankyou each and everyone who checks out my posts, I 'm glad to have y'all.
Stay tuned and Happy Coding.🚀

Getting the hang of Redux all at once can be a bit tricky. This quick overview offers a basic idea, but to truly dive into Redux, it's like needing more time for a friendly chat and a separate session to really get the hang of it. I advise you all to go and explore Redux, any questions are welcome here.
See you tomorrow for the 11th day of #20DaysOfReact!
