@ -19,20 +19,21 @@ This library exposes three main classes: `Model`, `MongoService` and `MongoTyped
`Model` is class with no real functionality; however, it represents a basic MongoDB document, and your services should host inherited classes.
```dart
@Hooked()
class User extends Model {
String username;
String password;
}
Db db = new Db('mongodb://localhost:27017/local');
await db.open();
app.use('/api/users', new MongoTypedService<User>(db.collection("users")));
app.service('api/users').afterCreated.listen((HookedServiceEvent event) {
print("New user: ${event.result}");
});
main() async {
Db db = new Db('mongodb://localhost:27017/local');
await db.open();
app.use('/api/users', new MongoTypedService<User>(db.collection("users")));
app.service('api/users').afterCreated.listen((event) {
print("New user: ${event.result}");
});
}
```
