+# Dioxus SSR
+
+Render a Dioxus VirtualDOM to a string.
+
+```rust
+// Our app:
+const App: FC<()> = |cx| cx.render(rsx!(div {"hello world!"}));
+
+// Build the virtualdom from our app
+let mut vdom = VirtualDOM::new(App);
+
+// This runs components, lifecycles, etc. without needing a physical dom. Some features (like noderef) won't work.
+vdom.rebuild_in_place();
+
+// Render the entire virtualdom from the root
+let text = dioxus_ssr::render_root(&vdom);
+assert_eq!(text, "<div>hello world!</div>")
+```
