+## @vue/babel-helper-vue-jsx-merge-props
+
+A package used internally by vue jsx transformer to merge props spread. It is required to merge some prop trees like this:
+
+```js
+import mergeProps from '@vue/babel-helper-vue-jsx-merge-props'
+
+const MyComponent = {
+  render(h) {
+    // original: <button onClick={$event => console.log($event)} {...{ on: { click: $event => doSomething($event) } }} />
+    return h(
+      'button',
+      mergeProps([
+        {
+          on: {
+            click: $event => console.log($event),
+          },
+        },
+        {
+          on: {
+            click: $event => doSomething($event),
+          },
+        },
+      ]),
+    )
+  },
+}
+```
+
+This tool is used internally and there is no reason for you to ever use it.
