Here is a list of amazing tricks that you can use to improve your React application. These tips not only make your code more clear and reliable but also aim to make the overall development experience easier and more enjoyable.
Try these methods in your React project today!React Query not only gives you more control over the ability to create HTTP requests and easily retrieve data in React applications with useful bindings, but it also enables us to seamlessly manage state across our application components, often without having to update manually. State.
You can do this with the useQuery hook, which takes an identifier for our query (in this case, since we're fetching user data, we'll call it 'user'), plus a function that uses it to fetch data is done.
import { useQuery } from React Query;
export defaultFunctionimplementation() {
const { isLoading, isError, data} = useQuery("user", () =>
fetch("//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, React Query takes care of handling these various instances that can happen when we get our data. We no longer need to manage these instances ourselves, we can just destroy them with the functions returned from the use Query .
React Context is a great way to pass data through our component tree. It allows us to pass data to any component without using properties.
To consume the context in the React Function component, we use the UseContext.
However, there is a slight disadvantage in doing so. In each component we want to consume the data passed in the context, we have 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 context, we can simply 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 provider>
<main />
</username
}
main work() {
const user = UserUser(),
return <h1>
{user.name} </h1>; //displays "red"
}
ReactDOM.render(
<provider3>
<2 save>
<provider1>
<application />
</provider1>
</provider2>
</provider3>,
root element
);
Instead of putting all our context providers in an App.js file or index.js file, we can create a component called Context Providers.
export defaultFunctionimplementation() {
const data = {
Title: "My Wonderful App",
Greeting: "Hello!" handjob
ShowButton: True
} ;
return <header {... data } />;
}
