shelf VS Echo

Shelf

To be honest, there's not much to it! It's a single-file add-on for the shelf package with about 100 lines of code, and the comment for the ProxyHandler class at the top sums up the shelf-proxy package pretty well:

The Dart Language Tour has all of this basic stuff but better, and when you're done, look at the shelf package on pub.dev if you want to get started on creating a server.

These are the best backend frameworks for Dart right now but you can use the shelf package if you want a slightly different approach

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.

Thats all what I found - https://github.com/dart-lang/shelf/issues/29 Looks like this is the most recent updated package, not very well know, which can handle cookies - https://pub.dev/packages/shelf\_secure\_cookie

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.

Echo - web framework for Go

The three behaviors I've described that we want all depend on two things, the first of which is "idiomatic error handling". We need to be able to simply return err in our handlers. Unfortunately, the standard libray doesn't give us this. But some third-party frameworks do. The most popular one I'm familiar with is labstack echo, whose HandlerFunc looks like this:

In this tutorial, I will be using the Echo framework to build the backend. You can learn more about Echo here.

If you come from NodeJS background, you may find Echo (https://echo.labstack.com) most similar to express.

Can I try to rewrite it using the following? I'll just hand you the code I don't care about credit, I just enjoy cleaning things up. - https://github.com/spf13/cobra - https://echo.labstack.com/ - SQLite - and not a bunch of if statements

Use a library for HTTP serving, such as Gin, Chi, or Echo. I personally use Chi, as it's just the right level of abstraction for how I like to work. Despite what others say here, don't try to re-implement everything in a modern serving library using the standard library.

Here I'm not really sure what you're referring to: * You can set request timeout and it has nothing to do with whether you handled your error or not. * In most cases you either bubble it up the callstack or do something with error in place you o received it i.e. you switch to default value, retry or sth along those lines. In some cases frameworks like echo will translate error into 5XX response for you if you don't do anything with it in top level handler. * Panics are recoverable. Also in case your handler panics it won't crash entire server -> stdlib HTTP server just closes connection, frameworks might even provide panic handler which will return 5XX instead of nothing. * try/catch doesn't really solve anything I mentioned here ¯_(ツ)_/¯. You just hope somebody caught your exception somewhere else.
