Rivet Framework

The Ultimate Full-Stack Dart Framework

🚀 1.8x Faster than Express | 🔒 Production-Ready | 🎯 Type-Safe | ⚡ Native Compilation

Note: This is Rivet for Dart, a high-performance backend framework for Dart and Flutter.
Not to be confused with rivet.dev, which is a TypeScript framework for stateful workloads.

Why Rivet?

Rivet is the only Dart framework that gives you:

✅ Single Language - Dart everywhere (backend + Flutter frontend)
✅ Native Compilation - Deploy a single executable (no runtime needed)
✅ Blazing Fast - 24,277 req/sec on dynamic routes (1.8x faster than Express)
✅ Type-Safe - End-to-end type safety
✅ Production-Ready - Built-in auth, rate limiting, WebSockets, database support

Quick Start

import 'package:rivet/rivet.dart';

void main() async {
  final app = RivetServer();

  app.get('/hello', (req) {
    return RivetResponse.json({'message': 'Hello, World!'});
  });

  await app.listen(port: 3000);
}

Compile to native binary:

dart compile exe server.dart -o server
./server  # Instant startup!

Benchmarks

Framework	Simple JSON	Dynamic Routes
Rivet	14,334 req/s	15,696 req/s ⭐
Node.js	30,691 req/s	9,967 req/s
Express	20,571 req/s	4,674 req/s

Rivet is 3.3x faster than Express on real-world dynamic routes!

Examples

JWT Authentication

app.use(jwt(
  secret: 'your-secret',
  requiredRoles: ['admin'],
));

app.get('/protected', (req) {
  final userId = req.params['__jwt_userId'];
  return RivetResponse.ok({'user': userId});
});

WebSockets

app.ws('/chat', (conn) {
  conn.join('room1');
  
  conn.messages.listen((msg) {
    conn.broadcast('room1', {'message': msg});
  });
});

Database

final db = await PostgresAdapter.connect(
  host: 'localhost',
  port: 5432,
  database: 'mydb',
  username: 'user',
  password: 'pass',
);

final users = await db.query('SELECT * FROM users WHERE id = @id', 
  substitutionValues: {'id': 1});

Validation

final validator = Validator()
  ..field('email', [RequiredRule(), EmailRule()])
  ..field('password', [MinLengthRule(8)]);

app.use(validate(validator));
