Takes care of errors.
Useful for tasks like updating the database.
router.post '/user/:id',
exec (req, next) -> dao.user.update req.params.id, req.body, nextrouter.post '/user/:id',
dao.user.update req.params.id, req.body, (err) ->
if err?
res.writeHead 500
res.end 'Internal Server Error'
else
next()bind was developed with snd during a project.
The initial idea is from snd.
I refactored the library and provided unit tests.
