useEffect(() => {
async function fetchPlaces() {
setIsFetching(true);
try {
const places = await
fetchAvailablePlaces();
navigator.geolocation.getCurrentPosition((position)=> {
const sortedPlaces = sortPlacesByDistance(
places,
position.coords.latitude,
position.coords.longitude
);
setAvailablePlaces(sortedPlaces);
setIsFetching(false);
})
} catch(error) {
setError({
message:
error.message || 'Could not fetch places, please try again later'});
}
setIsFetching(false);
}
fetchPlaces();
}, [])
if(error) {
return(
);
}
** Separate file for fetching and getting data **
export async function fetchAvailablePlaces(){
const response = await
fetch('http://localhost:3000/places');
const resData = await response.json();
if(!response.ok) { throw new Error('Failed to fetch places'); } return resData.places;
}
I would like to know how is this approach to handle error while building react app.
