 ## Vue DevTools
 
 Since Feathers-Vuex extensively uses Vuex under the hood, you'll want to make sure your VueJS developer tools are up to date AND setup properly.  Specifically, the "New Vuex Backend" needs to be enabled.  To setup the devtools

+## Preventing Memory Leaks
+
+The default settings of Feathers-Vuex include having realtime events enabled by default.  This will result in increased memory usage over time on the SSR server.  It can be turned off when you configure `feathers-vuex`.  The example below has been modified from the example of [Setting up the Feathers Client & Feathers-Vuex](./api-overview.md#feathers-client-feathers-vuex).  Look specifically at the `enableEvents` option.
+
+```js
+const { makeServicePlugin, makeAuthPlugin, BaseModel, models, FeathersVuex } = feathersVuex(
+  feathersClient,
+  {
+    serverAlias: 'api',
+    idField: '_id',
+    whitelist: ['$regex', '$options'],
+    enableEvents: process.client // No events for SSR server
+  }
+)
+```

 ## Working with Auth & Nuxt
 
 `[email protected]^` ships with utilities that help with Nuxt auth related to JSON Web Tokens (JWT).  The most important utility is the `initAuth` utility.  It's for use during Nuxt's `nuxtServerInit` method, and sets up auth data automatically.
