Hey 👋

@mewben

I'm having this type of usePosition() issue in my react app component. I have the most up to date version, so maybe I'm totally misusing this hook, but I'm not sure how to reduce the number of times that useEffect will call to the API.

Component Snippet

import { usePosition } from 'use-position';
import axios from 'axios';
import UseCurrentPosition from './UseCurrentPosition';
    
const LocalForecast = (props) => {
    const watch = true;
    const { latitude, longitude } =  usePosition(watch, {enableHighAccuracy: true, maximumAge: 300});
    const [ weather, setWeather ] = useState([])
   
    const location = {
       'latitude': `${latitude}`, 
       'longitude': `${longitude}`
    }

    useEffect( () => {
        if(latitude){
            axios.get('http://localhost:8080', {
                params: {
                    lat: latitude, 
                    lon: longitude
                }
            })
            .then((response) => response.data)
            .then((data) => setWeather(data))
            .catch(err => console.log(err));
            console.log(weather)
        }
    }, [location])

console.log repetitions of weather data

Thanks 🙌

watch: boolean - set it to true to follow the location.

Hi @techieeliot I believe watch=true constantly tracks your location therefore throwing you new values everytime. If you're not interested to follow location changes, try watch=false. :) Hope this helps :)

Hey @mewben,
Thanks for explaining. That change did the trick.
