meteor-become

Allow a user of a Meteor application to act as another one.

Example

import { Become } from 'meteor-become'

Become.policy(function(fromUser, toUser) {
    return toUser.username.indexOf("quatrava") >= 0
});

if (Meteor.isClient) {
    Template.MyBecomeUserForm.events({
        "submit": function(event, target) {
            Become.become(anotherUserID);
            event.stopPropagation();
        }
    });
}

How It Works

• Client code calls Become.become()
• Become.become() saves the current session token and calls the Meteor login function
• Server checks policy function (set with Become.policy) and returns success or error to client
• Upon success, Meteor.userId() etc. get updated on the client as is normal upon Meteor login
• Client may now call Become.restore() to restore the previous session token and reconnect

Dependencies

This code only works if called from a Meteor application. Furthermore, the following Meteor core packages are required (add them with meteor add if needed):

• promise
• session
• tracker
