I have a react app and I am using geolocated to get users location.
Following the instructions for the initialization I have wrapped the component:
export default geolocated({
positionOptions: {
enableHighAccuracy: true,
},
userDecisionTimeout: 15000,
})(ShowPois);
As soon as the user accepts (allows) the location finding on the browser I want two things to happen.
First I need to set a flag when then location is available to the app, so I have this:
static getDerivedStateFromProps(props, state) {
if (!state.geolocatedReady && props.coords) {
return {
geolocatedReady: true
}
}
return null;
}
Notice that props.coords comes from geolocated
The second thing is that I want to complete an input box with the address of the location found. In order to do this I have to do a post request to an api to get the address, but the problem is I cannot use the getDerivedStateFromProps() method because the method must return a value, not a promise (made by axios post request).
So how can I make a post request and then set the state when a prop changes in the component?
getDerivedStateFromProps
is only for edge cases . The case you have here sounds like a fit for componentDidUpdate
.
componentDidUpdate() {
if(!this.state.geolocatedReady && this.props.coords) {
this.setState({
geolocatedReady: true,
});
this.getAddress(this.props.coords);
}
}
getAddress = async (coords) => {
const address = await mapApi.getAddress(coords);
// or whatever you want with it.
this.setState({
address
})
}
