This is a wonderful summary but I'm struck with how these things all seem unnecessarily complicated compared to Python' requests, Apache Commons clients, curl based libraries... I get that a lot of magic also comes from the Erlang resilience, and maybe the functional composing is certainly interesting, but JavaScripts and Clojure and arguably you could do this with anything with promises... Anyway. This sounds great…

I realized that I needed to know way more about HTTP than I wanted to when trying to write a bunch of API wrappers for crypto exchanges. There’s just… a lot of failure modes and the application needs to respond differently to each. Some failures just need a quick retry while others must be pushed all the way back to a client to decide what to do.

Very cool. Can we see a similar one for HTTP servers ?

I've used HTTPoison, Tesla and more recently Req for a thin Firebase client.

I guess they all work.

I remember at some point HTTPoison & hackney were finicky with SSL certificate validation. But AFAIK HTTPoison is the only one that can do async requests to process chunks? [0]

This was great, selfishly I really wish we had an up to date comparison of HTTP clients like this but for Clojure.

Rather than post a top-level comment, I'll just tell you here that your content is _so good_ and I really appreciate what you're doing.

Is it a bad idea to use Tesla? I’ve got it in my app, but I never know.

I'm also curious why Tesla doesn't get mentioned in here, particularly because I'd argue that Tesla is at a similar abstraction level to Req.

For the same reasons that the author dislikes Tesla, I prefer it :D

To clarify: it's the same reason that I like plug.
