Best practices for REST API design

Posted on by

Over on the StackOverflow blog: Best practices for REST API design. Some of it is good but I disagree with a bunch of things. I made some notes:

* Use singular

https://www.example.com/comment/list

Not:

https://www.example.com/comments


* Use multidimensional selectors, not path/hierarchical selectors:

https://www.example.com/comment/list?artist=nirvana&album=nevermind

Not:

https://www.example.com/album/nirvana/nevermind/comments


* Use noun/verb format:

https://www.example.com/comment/list
https://www.example.com/comment/register
https://www.example.com/comment/edit/54688
https://www.example.com/comment/view/54688
https://www.example.com/comment/reply/54688


* The [ noun, verb ] pairs map to Facilities for implementation:

[ comment, list ] => CommentLister
[ comment, edit ] => CommentEditor
[ comment, view ] => CommentViewer

Facilities have submit/render functionality and round-trip view state.


* HTTP success 30x's not 2xx's.


* Include a 'submission ID' on <form> elements for idempotent operations


* GET and POST only, don't CRUD URLs, rather invoke business processes

Common C libraries and data structures

Posted on by

Today I discovered: Common C libraries and data structures. (C99) over on github. So awesome.

I really like the project layout too. Each module in a directory with an example, a bunch of tests, and some documentation to go along with the code. I feel like this is how it should be done. I think today I grew as a programmer because I read this code.
