Geolocation Storage

This library exists because I needed a portable tool to manage geolocations in browser.

How to use it

I develop this library in TypeScript, it auto-build when you install it in others projects.

It adds a UMD global var named WatchPosition that is a function who take 1 optional parameter, which is PositionOptions object type from DOM library.

window.WatchPosition({/* ... */})

This function return a new instance of my PositionSubscriber class.

This class have some public properties and methods:

Getters

name	type
watching	boolean
savedLocation	Position | null
previousLocation	Position | null

Methods

method	prototype
subscribe	(callback: PositionSubscriberCallback) => void
unsubscribe	(callback: PositionSubscriberCallback) => void
watch	() => void
stopWatch	() => void

The PositionSubscriberCallback type is the following :

type PositionSubscriberCallback = (position: Position, prevPosition?: Position) => void
