Reactjs React Fetch Response Successful But Setstate Not Working

Reactjs React Fetch Response Successful But Setstate Not Working From this, i can gather that the final step of the fetch call is not succeeding, because this.setstate({ title: "edit", loading: false, projectdata: data }); is clearly not having any effect on the page data. When you update the state using react’s setstate function, the state change is not applied immediately. instead, react batches state updates for performance reasons, applying them asynchronously .

Reactjs React Fetch Response Successful But Setstate Not Working One possible reason for setstate not updating the state is incorrect usage of the method. it is important to remember that setstate is asynchronous and batched for performance reasons. this means that multiple setstate calls may be grouped together and executed in a single batch. Enter setstate() that takes an updater function, or functional setstate (). functional setstate() takes an updater function as a parameter: the updater takes the previous state and the current props as parameters, and returns an object that will then be merged with state. You should not call setstate() in the constructor() . instead, if your component needs to use local state, assign the initial state to this.state directly in the constructor …. You are trying to update the state of your react app with the usestate hook. you call the setstate function with the new value but then when you try to use that state, you find that it hasn't updated yet!.

You are trying to update the state of your react app with the usestate hook. you call the setstate function with the new value but then when you try to use that state, you find that it hasn't updated yet!. Updating react state directly can lead to unexpected behavior and bypass react's reconciliation process. it's recommended to use the setstate function to ensure proper state updates. Think of setstate() as a request to update the component. reading state right after calling setstate() a potential pitfall. returns a stateful value, and a function to update it. the function. Setstate operation is asynchronous in react. if you new state depends on the values of the old state, you should use a functional form of setstate. Here’s a summary of the issue: the fetch request successfully gets data from the api. the data is stored in the component’s state. despite updating the state, the frontend doesn’t reflect the changes, and nothing is shown. checked the network tab, and the api response is fine (status 200). verified the state is being updated correctly in react.
