LetMeServe

A tiny abstraction around HttpServer (still in progress) Mostly for json requests

Provides simple usage for Router, Controller and Middleware Also a Json Validator

Example usage

Create a controller

class TodosControllerV0 implements Controller {
    Future<Response> getTodoById(Request request) async {
        final id =  request.params['id'];
        ...
    }

    Future<Response> createTodo(Request request) async {
        final body = request.body;
        ...
    }
}

Create a router than forwards the requests to a controller

class TodosRouterV0 extends Router {
    final TodosControllerV0 controller;

    TodosRouterV0(
        this.controller,
    ): super(prefix: '/api/v0');

    @Route.get('/todo/:id')
    Future<Response> getTodoById(Request request) => controller.getTodoById(request);

    @Route.post('/todo') createTodo(Request request) => controller.createTodo(request);
}

Create the server

void main() {
    ...

    final server = LetMeServe(host: 'localhost', port: 3000);

    await server.listen(() => print('server running'));
}

Add middlware (Optional)

class LogMiddleware extends Middleware {
    @override
    Future<Request?> onRequest(Request request, void Function(Response response) abort) {
    }

    @override
    Future<Response> onResponse(Response response) {
    }
}

class AuthMiddlware implements Middlware { ... }

/// applies to all methods annotated with @Route.[method]
@AddMiddlware(LogMiddleware)
class MyRouter extends Router {
    /// applies to
    @AddMiddlware(AuthMiddlware)
    @Route.get('/path/to/my/route')
    Future<Response> myRoute(Request request) { ... }
}

Json Validator (Optional)

    final validator = JsonValidator()..isString('name', minLength: 3)..isInt('age', min: 18);

    final errors = validator.validate({'name': 'my name is', age: 26});
