Check if username exists in Meteor

Been digging around for a solution but none for Meteor. If any, please let me know. I want to check if a username is already taken.

I understand that this only works on the server side only:

u = Accounts.findUserByUsername('foo');
console.log(u.username); #=> foo

I cant get my head around their pub/sub as I can only see information based on the current user. Is meteor saying that what I want is not possible?

When a user is filling out their details upon registration, I want them to be alerted (as they type) if the username they are using is already taken. But that logic I can easily code but need to know how to talk to the server to tell me the information.

You could write a Meteor method for that:

Meteor.methods({
  doesUserExist(name) {
    return Accounts.findUserByUsername(name) != null;
  }
});

Note that you have to define this method on the server but not on the client (e.g., by defining it in a file inside the server directory). That way Meteor won't try to simulate it on the client (which would fail because Accounts.findUserByUsername is not defined there).

Call the method as the user types:

Meteor.call('doesUserExist', name, function(error, result) {
  // `result` is true if the user exists.
});
