is it ok to use the exports keyword with commonjs - webpack 1

help you fix your problem Yes, you'd be right in saying using exports like that isn't valid es6 and is only working because babel transpiles your code into commonjs.
Webpack 1 doesn't support tree shaking so it shouldn't cause any problems there. It would be interesting to see what happens if you disable transform-es2015-modules-commonjs and use Webpack 2 to see whether it does effect tree shaking -- I highly doubt it will though.

will be helpful for those in need Yes. I often use this practice myself. It's also a good fit with the revealing module pattern, e.g.:
code :
module.exports = function(db) {
    return {
        get: function(id, callback) {
            // db.get(...)
        },
        save: function(obj, callback) {
            // db.save(...)
        }
    }
};

With these it helps While JSDoc issue 456 seems relevant that's not getting us anywhere yet.
I had a look at Use JSDoc: @alias which, while promising, did not offer the same JSDoc output.
code :
/**
 * This is a description
 * @module someModule
 */

(function() {

    // export to window when not used as a module
    if(typeof exports === 'undefined') {
        var exports = window;
    }

    /**
     * Returns true if something.
     * @param {String} type
     * @returns {boolean}
     * @static
     */
    exports.isSomething = function(type){
        return true;
    };
})();
var mm = require('./module.js');

console.log('--Testing nodejs--');
console.log(mm);
--Testing nodejs--
{ isSomething: [Function] }
<script src="module.js"></script>
<script>
    console.log('--html script test--');
    console.log(isSomething.toString());
</script>
"--html script test--"
"function (type){
    return true;
}"

it should still fix some issue Yes, you can use destructuring in the same way in node v6 and superior. More info here: Destructuring in Node.JS
Example:
code :
const { findIndex, last } = require('lodash');

help you fix your problem Insted of exporting the whole module I just exported each function individually:
code :
function makeStep (pin) {
        rpio.open(pin, rpio.OUTPUT, rpio.LOW);

        /* On for 1 second */
        rpio.write(pin, rpio.HIGH);
        rpio.sleep(0.0001);

        /* Off for half a second (500ms) */
        rpio.write(pin, rpio.LOW);
    }

module.exports = {
    makeStep
}
var motorDriver = require('./motorDriver');

io.on('connection', function (socket) {
    var motor = motorDriver

    socket.on('make step', function () {
        console.log("Make Step");
        motor.makeStep(40)
    });
});
