Answer 1

I think what you're looking for is

import * as io from 'socket.io-client';

This is the equivalent to

var io = require('socket.io-client');

in node.

However since this is running in the browser you will need to use a module loader of some sort to patch the references together. Typescript will compile happy, but browser will throw runtime errors if you don't configure the module loader correctly.
