appengine-value is a simple utility library to handle simple secret configuration values in an App Engine app.

Problem

Your app requires secret values (OAuth secrets, API keys, passwords) and you rightly don't want to specify these values as consts in your source code.

Solution

import "github.com/ImJasonH/appengine-value"
// ...
clientSecret := value.Get("client_secret")

That's it! The secret will be retrieved from datastore, memcache, or a map in local instance memory, whichever's faster.

To set or unset values, use the admin UI which is served at /_ah/value/admin -- be sure to map this in your app.yaml:

handlers:
- url: /_ah/value/.*
  script: _go_app
  login: admin

(You can always remove the mapping if you're done setting values)
