Network Information Api polyfill
An attempt to create polyfill for this specification. Polyfill is based on pinging some url and latency analysis. These are pretty rough measurements. But better than nothing.
Usage
npm i -S network-information-api-polyfill
or just
Then you need to initialize it
;
Polyfill must do the first request, to get information about network. So you can't use it synchronously, only using promise.
Configuring
You can pass options during initialization:
// here;
pingMaxTimeout
Type: number
Default: 5000
Timeout of request. After this time, the network will be considered unavailable (navigator.connection.type === 'none).
pingFrequency
Type: number
Default: 6000
A frequency of pinging.
pingUrl
Type: string
Default: ${location.protocol}//network-information-api.surge.sh/1b.txt
An url, that will be pinged. It is strongly recommended to have your own address. It improves the accuracy of measurements in relation to the user of your service.
CSP rules
If you have CSP rules, and you don't want own pingUrl
, you must add url
network-information-api.surge.sh to rule connect-src
.
