A redis based data structure that maps users and collaborators onto project names


A redis data structure for users collaborating on projects.


$ npm install collaborator-map


You need a Redis server running, you can provide the connection details to the constructor.

First - create a new map connected to the redis server:

var Collaborators = require('collaborator-map');
var map = Collaborators({
    // this will be prepended to all redis keys used by the map 

adding a project

When a user creates a new resource that requires access control - tell the map about the:

  • project id
  • owner id
  • access level
// project_id = binocarlos/countries 
// user_id = binocarlos 
// access = private 
map.create_project('binocarlos/countries', 'binocarlos', 'private', function(error){

getting access

There are 3 access levels a given user can obtain with a resource:

  • read
  • write
  • none

To get the access level for any user on a particular project id:

map.get_access('binocarlos/countries', 'otheruser', function(error, access){
    // from our example above access would be 'none' - the project is private 


The people who can write to a project (or read a private one) are called 'collaborators'.

By default the owner of a project is a collaborator (and cannot be removed as one).

You can added and remove collaborators to a project:

Add a user:

map.add_collaborator('bobsnewprojects', 'pete', next);

Remove a user:

map.remove_collaborator('bobsnewprojects', 'pete', next);

renaming projects

If for some reason you want to change the id by which you refer to a project:

map.rename_project('oldprojectid', 'newprojectid', next);

listing user projects

You can list the projects that a user can access.

The list contains objects with the following properties:

  • id - the project id
  • access - the access setting (public | private)
  • owner - whether the user is the owner of the project (true | false)
map.get_projects('bob', function(error, projects){
    // projects is an array of objects
