Geolocation

Once a user grants permission, Geolocation provides access to geographical location information from device.

Examples of usage

This HTTPs-only API exposes the navigator.geolocation object with a couple of useful methods:

  • .getCurrentPosition(successCallback, [errorCallback, options]) - "one shot" position request
  • .watchPosition(successCallback, [errorCallback, options]) - Watch a position and get notified of any changes.
  • .clearWatch(someId) - allows you to stop watching for location changes.

No location information is made available through this API without the user's permission.

navigator.geolocation.getCurrentPosition() method

Request the user's current location. If the user allows it, you will get back a position object.

navigator.geolocation.getCurrentPosition(position=>{const{ latitude, longitude }=position.coords;// Do something cool with latitude, longitude});

navigator.geolocation.watchPosition() method

Request the ability to watch user's current location. If the user allows it, you will get back continuous updates of the user's position.

constwatchId=navigator.geolocation.watchPosition(position=>{const{ latitude, longitude }=position.coords;// Do something cool with latitude, longitude});

navigator.geolocation.clearWatch() method

Finally, stop watching the user's location.

navigator.geolocation.clearWatch(watchId);

GeolocationPosition as JSON

You can also easily treat GeolocationPosition objects as JSON:

asyncfunctionsendPosition(){try{// Get the current positionconstposition=awaitnewPromise((resolve,reject)=>{navigator.geolocation.getCurrentPosition(resolve,reject);});// .stringify() calls .toJSON() automaticallyconstbody=JSON.stringify(position,null,2);// Prepare the fetch request optionsconstoptions={method: 'POST',headers: {'Content-Type': 'application/json'},
body
};// Send requestawaitfetch('https://example.com/api/positions',options);}catch(error){console.error('Error getting or sending position data:',error);}}sendPosition();

More examples

The specification provides examples covering different use case.
