Promisifying callback-oriented nodejs libs with ES6 (example)

promiseLib.js

export default function getPromiseLib(lib) {
    return new Proxy(lib, {
        get: (target, prop) => (...args) =>
            new Promise((resolve, reject) => {
                target[prop](...args, (err, ...params) => {
                    if (err) {
                        reject(err);
                    } else {
                        resolve(params);
                    }
                });
            }),
    });
}
