oleksmarkh / user.js

Created January 11, 2017 20:16

generic access control approach (user + resource [+ action])

	import { has } from 'lodash';

	// "user" assumed to always represent currently authenticated user
	// once this assumption isn't sufficient, the politic has to be extended
	// with something like:
	// * isCurrentUser(user, currentUser)
	// * belongsToCurrentUser(user, currentUser, resource)

	// a "resource" should at least have the "type" attribute for matching purposes
	// "user" is one possible detalization of a "resource" (e.g. 'const user = {type: "admin", profileId: 1, email: "[email protected]", ...}'),
