Usage

var Geolocation = require('browser-geolocation')
var geo = new Geolocation()

Start watching position

geo.start()

Initializes the data and starts watching.

This will remove all previous positions

Stop watching position

geo.stop()

Restart watching

geo.restart()

To use after geo.stop() to continue watching without initializing the data

Get all positions

var positions = geo.data

Get latest position

var position = geo.latestPosition

Position object

The positions are objects with the following keys:

• lat (latitude)
• lng (longitude)
• alt (altitude)
• timestamp (milliseconds since 1 January 1970 00:00:00 UTC)

Events

Listen to the following events

• 'start'
• 'stop'
• 'restart'
• 'position' (callback argument is the new position)

with

geo.on(<event-name>, function() {  })

For example

geo.on('position', function(pos) {
	console.log(pos)
	// logs latest postion
})

Convert to GPX

There is a separate library to convert geo.data to GPX: geolocation-to-gpx
