TIL the Network Information API

POSTED ON:

TAGS: javascript mobile

The Network Information API provides information about the system's connection in terms of general connection type (e.g., 'wifi', 'cellular', etc.).

Currently, it's implemented in mobile browsers.

navigator.connection.downlink can be used to select high definition content or low definition content based on the user's connection. You can easily determine the user's internet speed from JavaScript code using an object navigator.
