Node.js: How to get specific modules programmatically?

Main: How do i require modules that have example field in it's package.json?

For example:

const path = require( "path" );
const glob = require( "glob" );

const modules = glob.sync( './node_modules/*' );

for ( let mod in modules ) {
    const modPackage = require( path.resolve( __dirname, "node_modules", mod, "package.json" ) );
    if ( modPackage.hasOwnProperty( "example" ) ) {
        console.log( "Module:", mod, "Has Field 'example'" );
    }
}
