Fun GPT-4 use-case: comparing how different languages/frameworks solve common problemsMy prompt:> Show me code examples of different web frameworks in Python and JavaScript and Go illustrating how HTTP routing works - in particular the problem of mapping an incoming HTTP request to some code based on both the URL path and the HTTP verbDon't show installation instructions, just get straight to the code snippets.

Here's the resulting transcript. It gave me examples in Flask (Python), Express (Node.js) and Gin (Go) - then on further prompting added more examples for Django (Python), Koa (Node.js) and then Actix-web and Rocket for Rust:https://gist.github.com/simonw/fa2379b97420404a81b0fcdb4db79657

As someone who spends a whole lot of time on API design, this feels like a /really/ useful trick - researching how multiple frameworks across multiple other languages solve a problem is incredibly useful for coming up with a coherent new design

@simon interesting how the choice of port varies across these samples when not constrained, I guess it's keying off of idiosyncratic preferences from each of the represented communities

@simon If you want to see a super clean example, ask for an Elixir/Phoenix example. The power of macros.

@jimfl Neat tip, thanks - added that one to my collection

@simon Heh! I imagine RosettaCode.org is now obsolete, then. Makes me kinda happy; it had a good run. But I think GPT is ultimately a better model, since it doesn't require the information source pre-generate and pre-cache all the combinatorial space of task X language X library.

@simon I go really oblique and have been playing with things like “write a coroutine scheduler in bash in the style of Tolkien if he was a Haskell programmer”, works best against the less reinforced apis, and comes up with some really fun patterns. Also, doing things like the galactic pot healer telephone game: api in rust translate to go translate to Haskell and then back to typescript and finally rust, rinse repeat.

@simon Simon, I learn so much from all the examples and experiment you share. Thank you!

@simon The answers are all disappointingly the same.e.g. I think the system for this should auto-canonicalise this, and consist of the input function from URL ---> dict of view/parameters which matches URLs loosely in a configurable way (e.g. with without /, case insensitive, even spelling variations etc)Then a map from the dict of view/parameters to the definitive output URL. (This would also be used for URL generation)And then the framework automatically redirects to the canonical URL.

@simon a possible downside to this, though, is that it isn’t necessarily giving you the best answers and you may not be immersed enough to know. I personally wouldn’t recommend Gin as an example to be emulated, for example.

@joeshaw that's why I ask for lots of examples - I don't care about which one is "best", I want to see a wide range of different approaches to the same problem

What's wrong with Gin? The API design it used there looked pretty clean to me, reminiscent of Express

@simon My main complaint is that it doesn't conform to the standard http.Handler interface, so it makes interoperability with the vast majority of Go HTTP code out there difficult.
