Here is a list of amazing tips you can use to improve your React app. These tips don’t just make your code more clear and reliable but also aim to make the overall development experience easier and more enjoyable.

1. Replace Redux with React Query

As our application grows it becomes more and more difficult to manage state in our components, we can turn to a state management library like Redux.

If our application depends on the data received from the API, we often use Redux to retrieve this state from the server and then update the state of our application.

It can be a difficult process; Not only do you have to receive data, but you also have to handle different states depending on whether you have data or whether you are in a charging or error state.

Respond to the request not only gives you more control over the ability to easily create HTTP requests and fetch data in React apps with useful bindings, but it also allows us to transparently manage the state of our app components, often without having to update manually. State.

You can do this with the useQuery hook, which takes an identifier for our request (in this case, since we are fetching user data, we’ll call it “user”), as well as a function that uses it to fetch data is performed.

import { useQuery } from React Query;
export defaultFunctionimplementation() {
const { isLoading, isError, data} = useQuery("user", () =>
fetch("https://randomuser.me/api"). then ((resolution) => res.json())
  );
if (isLoading)
returns "Loading...";
 if (isError) returns
"error!" ;
const user = data.
result [0];
return user.email;
}

As you can see, Respond to the request takes care of managing these different instances that can happen when we get our data. We no longer need to manage these instances ourselves, we can simply destroy them with the functions returned by use Query.

2. Simplify React Context with Custom Hooks

React Context is a great way to pass data through our component tree. It allows us to pass data to any component without using any properties.

To consume the context in the React Function component, we use the UseContext.

However, there is a slight downside to doing so. In each component we want to consume the data passed in the context, we need to import both the generated context object and React to grab the usage.

Instead of writing multiple import statements each time we want to read from the context, we can just create a custom React hook.

import react from "react";
const UserContext = React.createContext(),
function userProvider({children}) {
const user = { name:"red" };
return
<UserContext.Provider value = {user}> {children}
UserContext.Provider>;
}
user() function {
const context = React.useContext(UserContext);
if (context === undefined) {
throwing a new Error("useUser is not under UserProvider");
  }
return context
}
export defaultFunctionimplementation() {
Return (

{user.name} ; //displays "red" }

3. Manage context providers in a custom component

In almost any React app you build, you’ll need multiple context providers.

We need context providers not only for the React context we’re creating, but also from third-party libraries that depend on it (such as React Query) so that you can access your tools to the components you need.

After you’ve worked on your React project for a while, it will look like this:

ReactDOM.render(
<provider3>
<2 save>




provider3>,
root element
);

What can we do about this mess?

Instead of putting all of our context providers in an App.js file or index.js file, we can create a component called Context providers.

4. Easy scrolling props using object propagation operators

When it comes to working with components, we usually transmit data using props. We create a property name and set it equal to its appropriate value.

However, if we have too many properties to pass to a component, do we need to list them all separately?

A really easy way to pass all the props we love without having to type in all of the prop names and their associated values ​​is to use the {… props} template.

This involves putting all of the prop data into an object and publishing all of those properties individually in the component we want to pass them to:

export defaultFunctionimplementation() {
const data = {
Title: "My Wonderful App",
Greeting: "Hello!" handjob
ShowButton: True
} ;
return <header {... data } />;
}
