nano-promises
nano-promises
is a lightweight wrapper around the fabulous
nano
driver. It provides
the same features but uses promises instead of callbacks.
Example
;; var db = db; db ;
nano-promises
promises always resolve to a value of the form [body, headers]
or reject to a value of the form error
. So it is important to
use desructuring in the then
handler of the promise.
async/await
The above example does not seem convincing to swith to a promise-based
approach. nano-promises
becomes very handy when used together
with the async/await
proposal for ES7:
var { try var doc = await db; return doccrazy; catcherr console; throw err; };
I don't know about you but I find this very expressive!
Attribution
I love the nano
library. It has a very good api design and there's
a lot of work put into it!
The code in this repo is mostly adapted from co-nano
, but with
promises instead of thunks.
