NetworkInformation
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The NetworkInformation
interface of the Network Information API provides information about the connection a device is using to communicate with the network and provides a means for scripts to be notified if the connection type changes.
The NetworkInformation
interface cannot be instantiated. It is instead accessed through the connection
property of the Navigator
interface.
Note: This feature is available in Web Workers
Instance properties
This interface also inherits properties of its parent, EventTarget
.
NetworkInformation.downlink
Read only Experimental-
Returns the effective bandwidth estimate in megabits per second, rounded to the nearest multiple of 25 kilobits per seconds.
NetworkInformation.downlinkMax
Read only Experimental-
Returns the maximum downlink speed, in megabits per second (Mbps), for the underlying connection technology.
NetworkInformation.effectiveType
Read only Experimental-
Returns the effective type of the connection meaning one of 'slow-2g', '2g', '3g', or '4g'. This value is determined using a combination of recently observed round-trip time and downlink values.
NetworkInformation.rtt
Read only Experimental-
Returns the estimated effective round-trip time of the current connection, rounded to the nearest multiple of 25 milliseconds.
NetworkInformation.saveData
Read only Experimental-
Returns
true
if the user has set a reduced data usage option on the user agent. NetworkInformation.type
Read only Experimental-
Returns the type of connection a device is using to communicate with the network. It will be one of the following values:
bluetooth
cellular
ethernet
none
wifi
wimax
other
unknown
Instance methods
This interface also inherits methods of its parent, EventTarget
.
Events
change
Experimental-
The event that's fired when connection information changes.
