# `useAsync`
|
|
|
|
React hook that resolves an `async` function or a function that returns

|
a promise;

|
|
|
|
## Usage

|
// Returns a Promise that resolves after one second.
|
|
const fn = () => new Promise((resolve) => {
|
|
setTimeout(() => {
|
|
resolve('RESOLVED');
|
|
}, 1000);
|
|
});
|
|
|
|
const Demo = () => {
|
|
const state = useAsync(fn);
|
|
|
|
return (
|
|
<div>
|
|
{state.loading?
|
|
<div>Loading...</div>
|
|
: state.error?
|
|
<div>Error...</div>
|
|
: <div>Value: {state.value}</div>
|
|
}
|
|
</div>
|
|
);
