Too few sampled comments (2) to say how often HN recommends it.?

Why HN links it

Linked for a post suggesting the HTTP OPTIONS method could document REST APIs so client libraries can be generated, and for a post about Meow, a Growl work-alike.

Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

  1. Reminds me of how I got users to verify their ownership of Minecraft accounts[0]. There is no profile to add a token, but they can switch their skin, and you can download a user’s skin without being in-world. [0] http://zacstewart.com/2012/12/24/verifying-minecraft-user-ac...

  3. https://zacstewart.com/tags/phonium.html I did this a few years ago and got pretty far with a prototype. My idea was to get it to the point of being useful enough to call, text and allow me to leave my iPhone behind when I’m out doing stuff. Then I moved to Asia and we use LINE extensively for everything and there’s no (legit) way to use their APIs.

  5. It's a shame there isn't some simple standard (de-facto or otherwise) way of documenting REST APIs such that an idiomatic client library for each language could be generated automatically. The OPTIONS method is a really underused part of HTTP and would be great for this purpose: http://zacstewart.com/2012/04/14/http-options-method.html
