This package is a slim wrapper for the awesome JSforce npm package.
We expose a global Salesforce object on the client and server which is a standard JSforce connection object.
Check the JSforce documentation
Two methods login and query are wrapped server-side in Fibers to work synchronously without callbacks.
// server-side, no callbacks needed
Salesforce.login(user, pass, token); // gather these from Salesforce
var query = "SELECT Id,Name FROM Lead";
var result = Salesforce.query(query);
