Manual position request
import * as React from 'react';
import { useGeo } from 'use-geo';
// Or import useGeo from 'use-geo';
const stringifyResults = (status, position, error) => {
if (error) return `Error(${error.message})`;
if (position) return `{\n lat: ${position.coords.latitude},\n long: ${position.coords.longitude}\n}`;
return status;
};
export default () => {
const { status, position, error, request } = useGeo(/* immediate flag (boolean) or PositionOptions object */);
return (
<div>
<input
type="button"
value="reload"
onClick={request}
disabled={status === Status.PENDING}
/>
<pre>useGeo(): {stringifyResults(status, position, error)}</pre>
</div>
);
};
Watching position changes
import * as React from 'react';
import { useGeoWatch } from 'use-geo';
const stringifyResults = (position, error) => {
if (error) return `Error(${error.message})`;
if (position) return `{\n lat: ${position.coords.latitude},\n long: ${position.coords.longitude}\n}`;
return 'No results';
};
export default () => {
const { position, error, watching, watch, unwatch } = useGeoWatch(/* immediate flag (boolean) or PositionOptions object */);
return (
<div>
{watching ? 'watching' : 'not watching'}
<input
