circles-npm

Node sdk for https://github.com/linnovate/circles

Overview

The circles npm provides several features that work together with the circles api to provide
organizational context to users and to enforce compermentalization of data (the ability to seclude permissions between types of users). When you use circles you can "sign" the data with it's appropriate circle (which represents who can consume it). A user can pull his "Circles" which basically communicate to what groups he belongs and what type of data can he consume. The circles npm provides

• The function to "sign" an object with it's circles
• The express middleware to add to your routes so they will allow or disallow access to content based on the circles signed on the content and sent to the api query.
• Access and helper functions to the circles api (getCircles, )

Configuration

Your app should reference a circlesApi instance and should have an (express style) config setting for circles api...

circles: {
    uri: 'http://localhost:3005'
  },

the circleSettings configuration could typically be set like this...

'use strict';

module.exports = {
	displayAllSources: false,
	displayAllC19nGroups: false,
	displayAllGroups: false,
	circleTypes: {
		c19n: {
			requiredAllowed: true,
			max: 1,
			sources: true
		},
		c19nGroups1: {
			requiredAllowed: true,
			max: 1,
			requires: ['c19n']
		},
		c19nGroups2: {
			requiredAllowed: true,
			max: 1,
			requires: ['c19n']
		},
		personal: {
			requiredAllowed: false,
			max: 50,
			watchers: true
		}
	},
	cacheTime: 5,
	cacheDb: 'mongoose'
};

Usage

var circles = require('circles-npm')(app, config.circles.uri, circleSettings);

Signing data

circlesAcl.sign('mongoose', entity.sources, entity.circles, acl, function(error, circles) {}

Middleware
