Exploring Typescript: Uncovering the Secrets of the navigator.connection Property

I am trying to access the NetworkInformation interface by using a simple TypeScript function like the one shown below:

private checkNetworkConnection(): void {
const connection = Navigator.connection
  || navigator.mozConnection 
  || navigator.webkitConnection;
 const type = connection.type;
 console.log('CONNECTION TYPE: %o', type);
 console.log('DOWNLINK: %o', connection.downlink);
}

However, I keep encountering the error message connection is undefined. After browsing on SO, I discovered that Cordova users extend the type definitions of Typescript by importing

@types/cordova-plugin-network-information
, but this doesn't resolve my issue.

You can view a working example on StackBlitz here.

Answer №1

This Angular enhancement package introduces a new type: https://www.npmjs.com/package/network-information-types

Integrate the package into your project:

npm install network-information-types

Next, update your typescript.json file:

{
  "compilerOptions": {
    ...
    "types": [
        "./node_modules/network-information-types"
    ]
  },
}

Important to note: Currently, only Chromium fully supports this type.
