Meteor password validation - meteor

Question

I'm struggling to figure out how to make password validation with my user Schema, that's how I've being doing so far:
This is the schema:
Schema = {};
Schema.UserProfile = new SimpleSchema({
//LOTS OF FIELDS WORKING FINE
});
Schema.User = new SimpleSchema({
username: {
type: String,
optional: true
},
emails: {
type: Array,
},
"emails.$": {
type: Object
},
"emails.$.address": {
type: String,
regEx: SimpleSchema.RegEx.Email
},
"emails.$.verified": {
type: Boolean
},
createdAt: {
type: Date
},
profile: {
type: Schema.UserProfile,
label: "Perfil",
optional: false
},
services: {
type: Object,
blackbox: true
},
"services.$": {
type: Object,
blackbox: true
},
"services.$.password": { // IS IT RIGHT?
type: String,
label: "Senha",
min: 8
},
roles: {
type: String,
optional: true
}
});
Meteor.users.attachSchema(Schema.User);
And this is how I'm saving:
let company = {};
company = {
email: $('#email').val(),
password: $('#password').val(),
roles: 'company',
profile: companyProfile
}
Meteor.call('saveUser', company, function(error, result) {
if ( error ) {
console.log(error);
}
}
Meteor.methods({
saveUser: function(data) {
return Accounts.createUser(data);
}
});
I'm still a beginner, so I'm probably messing something up here. When I try to create the user, if there is an issue with any of the fields, the validation throws an error as expected. However no error is thrown in case I miss the password, any ideas of what I'm doing wrong here?
------------------------------- UPDATE ----------------------------------
Thanks #aedm for your answer. I really wish I could have something like this to verify the password and password confirmation:
password: {
type: String,
label: "Senha",
min: 8
},
password_confirmation: {
type: String,
label: "Confirmação de Senha",
min: 8,
custom: function () {
if (this.value !== this.field('password').value) {
return "passwordMismatch";
}
}
},
I guess it's not possible then, is it?

Meteor only stores a bcrypt hash for the password, it's always longer than 8 characters.
Instead, your saveUser method should throw an error when the password criteria isn't met.
Meteor.methods({
saveUser: function(data) {
if (data.password.length < 8) throw new Meteor.Error("Password too short");
return Accounts.createUser(data);
}
});
I'd try to avoid defining a schema for users, Meteor handles it pretty well without one, and it's not trivial how to do it properly.
