Note: Don't forget to add --project core or else it will be added to the default project in your angular.json file.


Run ng build core to build the project. The build artifacts will be stored in the dist/ directory.


After building your library with ng build core, go to the dist folder cd dist/core and run npm publish.

Running unit tests

Run ng test core to execute the unit tests via Karma.

@todo: Update the following documentation to reflect CORE, as Auth was migrated into its own domain long ago


An authentication and authorization service built on Firebase and NgStore. Provides roles, permissions and user management, with plans for future asset-level Access Control Lists (ACLs).

About the data types


Permissions are simple objects, essentially just a key and an optional description. The list of all system permissions are stored in an object map, using the permission "name" as the key. This map is found at the root of the auth-system state object.

A typical system is expected to have no more than a few hundred permissions.


A Role is also a simple 'key-description' tuple, and all system roles are stored in a single object map at the root of the auth-system state object.

Because "a role has permissions", there is also a role-permissions map. This map is stored at the root of the auth-system state object, and contains an entry for each role that has any permissions assigned to it. That entry is itself a map, keyed by a permission name. The entry's value is of type 'PermissionGrant'.

Note: Permission Grants are scheduled for refactoring. The entry mentioned above should be shortened to a simple boolean instead of an PermissionGrant data structure.



Role based authorization is great, but it isn't actually supported by FireBase Rules in a generalizable way. So our Auth-Service will update a 'flattened' view of a user's permissions table when a permission is granted to or revoked from a role that is already assigned to a user. From a permission and rule management perspective it's fairly transparent, while also allowing FireBase Rules to match one-to-one with run-time permission checks.
