What is the process for assigning a predefined type that has already been declared in the @types/node package?

Is there a way to replace the any type with NetworkInterfaceInfo[] type in this code snippet? Unfortunately, I am unable to import @types/node because of an issue mentioned here: How to fix "@types/node/index.d.ts is not a module"?

Here is the original code:


import { networkInterfaces } from 'os';

// array.prototype.concat use type any
const getLocalExternalIP = () => ([] as any).concat(...Object.values(networkInterfaces()))
    .find((info: any) => { // any
        return info.family === 'IPv4' && !info.internal;
    }).address;

export { getLocalExternalIP };

I attempted to rewrite it like this:


...
// Cannot find name 'NetworkInterfaceInfo'.ts(2304)
const getLocalExternalIP = () => ([] as NetworkInterfaceInfo[]).concat(  ...
...

Do you have any suggestions on how to avoid using the any type in this specific scenario?

Answer №1

From my observation, the issue you are experiencing is related to an error:

// Cannot find name 'NetworkInterfaceInfo'.ts(2304)

This error occurs because you have not imported the module 'NetworkInterfaceInfo' explicitly from the 'os' library. To resolve this, you can import it like so:

import { networkInterfaces, NetworkInterfaceInfo } from 'os';
