+## Default Options
+
+- `changeOrigin` and `ws` options are enabled by default.
+
+You can provide default options to all proxy targets by passing options to module options:
+
+```js
+export default {
+  modules: [
+    // Disable ws option to all proxified endpoints
+    ['@nuxtjs/proxy', { ws: false }]
+  ],
+  proxy: [
+    'http://example.com/foo',
+    'http://example.com:8000/api/books/*/**.json',
+  ]
+}
+```
+
+This will be similar to:
+
+```js
+export default {
+  modules: [
+    '@nuxtjs/proxy',
+  ],
+  proxy: [
+    ['http://example.com/foo', { ws: false }],
+    ['http://example.com:8000/api/books/*/**.json', { ws: false }]
+  ]
