howto disable meteor accounts user registration?

Question

i am using meteor accounts for login and user registration.

When a user hits the bottom line (register):

He gets redirected to the create account page:

The code behind these pages is a mixture of jade templates and javascript.

template(name="userFormsLayout")
  section.auth-layout
    section.auth-dialog
      +Template.dynamic(template=content)

It seems like the content is replaced when hitting the register link and this is as far as my knowledge goes...

I would like to prevent users from creating new accounts by either disabling the final register button on the registration page and / or disable the complete registration page.

I am also open for other solutions to prevent useers from registering.

UPDATE: I also tried this

AccountsTemplates.configure({
  forbidClientAccountCreation: true

but got:

 Error: signUp route configured but forbidClientAccountCreation set to true!

Can anyone help me with this issue?

i don't have the whole answer, but i can give you a couple pieces to get you started.

first, you can tell AccountsTemplates (AT) to use your layout. you can put this anywhere that's loaded to both client and server, e.g. lib/atConfig:

AccountsTemplates.configureRoute('signIn', {
    layoutTemplate: 'LoginLayout'
});

here's the layout template:

<template name="LoginLayout">
    <main>
        <div>
            {{> Template.dynamic template=main}}
        </div>
    </main>
</template>

in the JS, you can hide the bits of the template you don't want the user to see. here, i'm hiding the password form and a separator. you can dig into the DOM to figure out which bits you want to hide:

Template.LoginLayout.onRendered(function() {
    this.autorun(() => {
        if (this.subscriptionsReady()) {
            Tracker.afterFlush(() => {
                $('.at-pwd-form').remove();
                $('.at-sep').remove();
            });
        }
    });
});

for the server, you can check for new user attempts and reject them if they're made w/ username and password. i think this should work, but you may have to play around with it:

import {Meteor} from 'meteor/meteor';

Meteor.startup(() => {
    /**
     * reject registration via username/password.
     */
    Accounts.validateNewUser(function(attemptInfo) {
        if (attemptInfo && attemptInfo.services && attemptInfo.services.password) {
            return false;
        }

        return true;
    });
});
