++ Write React, React Native, and Express applications entirely in Dart. + One language. Runtime type safety. Sound null safety. No compromises. +
+ + +// A complete Express server in Dart
+import 'package:dart_node_express/dart_node_express.dart';
+
+void main() {
+ final app = createExpressApp();
+
+ app.get('/', (req, res) {
+ res.json({'message': 'Hello from Dart!'});

+ app.listen(3000, () {

+const Counter: React.FC = () => {
+ const [count, setCount] = useState(0);
+
+ return (
+ <button onClick={() => setCount(c => c + 1)}>
+ Count: {count}
+ </button>
+ );
+}; ReactElement counter() {
+ final (count, setCount) = useState(0);
+
+ return button(
+ onClick: (_) => setCount((c) => c + 1),
+ children: [text('Count: $count')],
+ );
+}Hooks, components, props, state — everything you know from React works the same way in Dart.
+Unlike TypeScript, Dart preserves types at runtime. No more any escapes or erased generics.
No webpack, no babel, no tsconfig. Just dart compile js and you're done.
class Counter extends StatefulWidget {
+ @override
+ State<Counter> createState() => _CounterState();
+}
+
+class _CounterState extends State<Counter> {
+ int count = 0;
+
+ @override
+ Widget build(BuildContext context) {
+ return ElevatedButton(
+ onPressed: () => setState(() => count++),
+ child: Text('Count: $count'),
+ );
+ }
+}ReactElement counter() {
+ final (count, setCount) = useState(0);
+
+ return button(
+ onClick: (_) => setCount((c) => c + 1),
+ children: [text('Count: $count')],
+ );
