+## Configuring Node.js
+
+Node.js can alias `react-native` to `react-native-web` using
+[`module-alias`](https://www.npmjs.com/package/module-alias). This is useful if
+you want to pre-render the app (e.g., server-side rendering or build-time
+rendering).  
+
+```js
+// Install the `module-alias` package as a dependency first
+const moduleAlias = require("module-alias");
+moduleAlias.addAliases({
+  "react-native": require.resolve("react-native-web"),
+});
+moduleAlias();
