Hi everyone, and welcome to this video on the introduction of Redux.
In this video, we'll be discussing why
it's important to have a tool like Redux for managing your data in a react native
app, and also why you should consider using the newer tool called Redux Toolkit.
In a react native app,
managing data can quickly become complex and overwhelming as the app grows.
We don't want to be losing data and we do
want to reuse the data that we have as much as we can.
We also sometimes need access to the same kind of data from components and screens.
This is where a tool like Redux comes in,
providing a centralized place for managing your app state and data.
Redux is a popular state management library
that helps you manage the state of your react native app in a predictable way.
The core of Redux is the Store,
which is a single source of truth for your app state.
The store can only be updated
by dispatching actions, which are objects that describe what happened in your app.
Redux has several benefits, including predictable state management
because Redux follows strict rules for how the store can be updated,
making it easier to understand how your app state is changing.
Another advantage of using Redux is that it can be easily debugged.
As Redux has a centralized way of managing data, it is easier to find and fix
problems in your app, and this also makes it easier to manage and update your data.
Because it is a centralized place, the actions and reducers in Redux can be
reused across your app, reducing duplication of your code.
However, the disadvantage of Redux is that it has a steep learning curve and can
be verbosed, leading to an increase in boilerplate code.
And this is where Redux Toolkit comes in.
Redux Toolkit is a set of tools
and utilities for Redux that make it even easier to use.
It provides several advantages over Redux,
including easy setup and configuration, since it provides a streamlined setup
process and removes the need for manual configuration.
Reduced boilerplate is another advantage as the utilities provided by Redux Toolkit
simplify common tasks and reduce the amount of code you need to write.
And in general, you will have improved experience when using Redux as
the Redux Toolkit is improved, making it easier for developers
to understand and use Redux in their projects.
We'll be using the Donation app to develop
our Redux skills and see specific use cases of Redux in action.
This will give you a practical
understanding of how Redux works and how you can use it in your own projects.
In conclusion, Redux and Redux Toolkit are
both essential tools for managing data in a react native app.
They provide a centralized place for managing your state and data,
making it easier to debug and understand what's happening in your application.
The store in Redux serves as a single source of truth, and dispatching actions
allows you to update the store in a predictable manner.
Redux Toolkit improves upon regular redux
by reducing boilerplate code and improving the developer experience.
In the next video, we'll be installing in Redux toolkit, so stay tuned.
Thanks so much for watching and I'll see you in the next video.
