 # Feathers
+#### Changes in behavior
+With the initial setup of Feathers JS, it is possible to create users via the REST service. **This has been disabled for this boilerplate.** If you want to be able to create users via, for example, Postman, please adjust this code (which can be found in *src/services/users/users.service.js*):
+```javascript
+  // A bit of custom validation, before anything is stored/sent to the server.
+  service.hooks({
+
+    before: {
+
+      create( context ) {
+
+        // If the provider is not from socketio, then throw an error. Disallow creation of accounts from outside the website.
+        if( context.params.provider !== 'socketio' ) {
+
+          throw new Error('Unfortunately, we don\'t offer account creation externally. Please, create the account on our website.')
+
+        // Do a simple regex test of the password.
+        } else if( !passwordRegex.test( context.arguments[0].password ) ) {
+
+          throw new Error('Invalid password. Passwords has to contain between 6 - 64 characters, include a upper- and lowercase letter, a number and a symbol. ASCII characters are strictly forbidden.')
+
+        }
+
+      }
+
+    }
+
+  })
+```

+### Feathers Logger
+*Feathers comes with [winstonjs/winston](https://github.com/winstonjs/winston), a.k.a, Logger. This is also bound to the Vue instance, and triggers the VueNotifications:*
+```javascript
+Vue.Logger('error', 'This is an error.')
+Vue.Logger('warn', 'This is a warning.')
+Vue.Logger('info', 'This is some information.')
+...
+```
+### Notification options
+> error  
+> warn  
+> info  
+> success
+
+**Examples:**
+```javascript
+Vue.app.emit('error', 'Here\'s an error notification.')
+Vue.app.emit('info', 'Here'\s an information notification.')
+```
+*If you want to only log to console, just use `console.log`*
+You can find the following code in `~/layouts/default.vue`:
+```javascript
+// Listen to all errors, warnings, info and success events.
+        created: function() {
+
+            Vue.app.on('error', (message) => {
+
+                this.error({ title: 'Error', message: message, type: 'error' })
+
+            })
+
+            Vue.app.on('warn', (message) => {
+
+                this.warn({ title: 'Warning', message: message, type: 'warn' })
+
+            })
+
+            Vue.app.on('info', (message) => {
+
+                this.info({ title: 'Info', message: message, type: 'info' })
+
+            })
+
+            Vue.app.on('success', (message) => {
+
+                this.success({ title: 'Success', message: message, type: 'success' })
+
+            })
+
+        },
