Video Transcript
One of the most common things to joke about in JavaScript is that a new framework comes out every single day or every single week.
But we don't really talk about the fact that there's a new React library nearly every single day that deals with state management.
If you just go into NPM and search for React State Management Libraries, you can see you get a massive list of almost 2,000 results with libraries like Zootan,
JoyTai, Redux, and so on that you've probably heard of and maybe even used before.
Now in this video, I want to talk about why you probably don't even need a React State
Management library, the different tools that have come out that make State Management so
much easier that are built into the tools we already use, and a little bit of the history
about why these React State Management libraries came about, and why we no longer need them.
So if you've used a React State Management library before or are thinking about adding
one to your project, you need to watch this video to see what you can do instead, and
why you probably don't need them.
Welcome back to Web Dev Simplified.
My name is Kyle and my job is to simplify the web for you so you can start building your dream project sooner
And to really understand how state management has changed and why some of the libraries you don't need anymore
We really need to talk about the history going all the way back to when React started to figure out why a lot of these state management libraries were created
So in the very early days when React was first created you essentially have a component and inside this component is where all of your state
Lives for that individual component
So you have a component with state inside of it
And you also have some props that you can pass down into that component as well
And this is how everything works.
So you'd manage your state locally.
So if you have a get counter, you
would manage your account directly inside that component.
And that works really great for small things.
But as soon as your application gets more complex,
you probably have other components inside this component.
So now you have multiple components inside this component.
And you even have components inside of those components.
And each one of these components now
needs access to this exact same state variable.
So now you have to pass this down as a prop
to each individual component that you're using.
And the problem is that now those child components
needs to pass down that state to even further child components.
And this is the idea of prop drilling.
Where essentially you have state stored in one component that's apparent to a bunch
other components.
And you're constantly passing that state down through each individual component until
you get all the way down to the child component that needs it.
And this means that you're possibly passing state through like seven different components
that have no need for that state just because one of their children needs access to that
state variable.
So for example, you can have a component tree that looks like this where you have like four
or five different levels of nesting.
And you have a state right here in the parent component.
And the state that is in this parent component
is only needed in one place in the furthest child component.
But you have to pass it through every single child
to get all the way down to that individual
smallest child component.
