Suppressing Specific JSUnresolvedVariable Warnings

How can I cleanly suppress the warnings on unresolved variable for Node environment variables?  I don't want to have to keep putting this all over my code, that's just code smell and a terrible way to go about that IMO:

// noinspection JSUnresolvedVariable 

So how can I tell Webstorm to ignore all Node environment variables?

Here's some of my code using them:

import app from './app';

require('dotenv').config();
const { env } = process;
// noinspection JSUnresolvedVariable
app.listen(env.PROD_SERVICE_PORT, err => {
    // noinspection JSUnresolvedVariable
    console.log(`Koa is listening on port ${env.PROD_SERVICE_PORT}`);
    if (err) {
        console.log('server startup error');
        console.log(err);
    }
});
