![]() It only returns the state variable or function that you want to use in a component. The difference between React hook and a React component is that hook doesn't return JSX. Inside the file, create a new function with the name of the hook. The name of the hooks starts with use as a part of react hooks convention. ![]() We first create a new javascript file with the name useFetch.js. Like useState and useEffect have their function, we create custom hooks by combining them for a specific ability. This makes the code efficient and easily maintainable. We can write the code in a separate js file and call it with URL from all the components that might need to fetch the data from the server. That's where the real magic of Custom Hook is. 2009Buziol GamesSoftendoMario Forever 4.154.4Mario Forever Advance EditionMFAE. In big codebases, it is better to follow the Don't Repeat Yourself (DRY) principles, that is, it's better to write code once and make it reusable instead of writing it again and again in multiple components. We have to rewrite all of these codes multiple times in all of those components which is not very efficient and hard to manage. While it's perfectly fine to write like this, what if we want to do the same kind of thing in multiple components where we have to fetch another data. We write the logic inside the useEffect hook to update the state properties like data, loading, and error. ![]() The normal code for fetching the data from the server and updating in the component is shown belowĮnter fullscreen mode Exit fullscreen mode It also makes the code more readable, efficient, and easy to maintain. The hooks can be used in multiple components where we have to use a specific function. One of the main advantages of using React hooks is the re-usability of logic. Some of the built-in hooks provided by React are useState, useEffect, useContext, useReducer, useRef, useCallback, and useMemo. They are functions that let you hook into React state. React hooks were first introduced in React 16.8. It is then used in components for showing it in the view.īefore jumping into the code of how's it's done, let's first look at what React hooks are and why it is used. We retrieve the data using the API call and using built-in React hooks like useState, useEffect, and useReducer, the retrieved data is set to the state variable. For every application to work dynamically, it fetches the data from the server and then displays it in the user interface. Mario Forever 6.0 LiveSplit splits I want to start speedrunning Mario Forever and Im looking for pre-made splits for LiveSplit or if someone could tell my how many levels are there in every world, that would work fine too. Fetching data from the backend is one of the crucial parts of the web application.
