shelf VS jaguar

In this blog, I will talk about the benchmarks of Flask (Python), Express (JavaScript), Shelf (Dart), dart_frog (Dart) and Conduit (Dart), and my opinions on Dart on the server side.

There was a time, I want to start a new project and have to choose what technologies to use for the frontend and backend parts as well. Research gets me to Aqueduct and Shelf, both of them weren't looking actively developing and supported and that leads me to the idea to make my own small micro-framework like Echo for Golang or Bottle for Python. And it was easy to decide: I've had time and motivation :)

Dart Frog 🐸 es un framework web construido sobre Shelf inspirado por Next.JS, Remix y Express.

We are't using one of the frameworks for Dart on the backend (Conduit, Dart Frog) and instead built on top of shelf for both the projects we've used Dart on the backend for - one we went for a gRPC approach and the implemented a REST API.

We also need a software service that we already built in the videos mentioned above. The service we want to deploy will use the shelf server from Dart hat we already run locally and make our first requests. But this will also work if you use a aqueduct server or a conduit server.

The shelf package has always looked very well-written to me. I like the way functions and function typedefs are preferred over classes, how it uses short and simple source files, and usages of streams for requests and responses. This package makes good use of language and SDK features that only work in Dart.

| console-simple | A simple console application (basic template). | | ---------------- | -------------------------------------------------- ----- | | console-full | Console application with tests. | | package-simple | A starting point for Dart libraries or apps. | | server-shelf | Server based on shelf. | | web-simple | Web application with core libraries. |

You might want to look at shelf. The whole backend of pub.dev runs on that.

https://pub.dev/packages/shelf import 'package:shelf/shelf.dart'; import 'package:shelf/shelf_io.dart' as shelf_io; void main() async {  var handler =  const Pipeline().addMiddleware(logRequests()).addHandler(_echoRequest); var server = await shelf_io.serve(handler, 'localhost', 8080); // Enable content compression  server.autoCompress = true; print('Serving at http://${server.address.host}:${server.port}'); } Response _echoRequest(Request request) =>  Response.ok('Request for "${request.url}"');

The only remaining major server-side framework is Jaguar. Though the maintainer has stated that they will continue to maintain the project, there had been a five-month gap between the last two commits (there was, however, a null-safety commit yesterday).
