Security - Roles

Every ability in Eicrud is attached to a role. Roles are dynamically assigned to users via the property CrudUser->role.

eicrud.roles.ts

import { CrudRole } from "@eicrud/core/config";

export const roles: CrudRole[] = [
    { 
        name: 'admin', 
        isAdminRole: true,
        canMock: true,
        inherits: ['user']
    },
    { 
        name: 'user', 
        inherits: ['guest']
    },
    { 
        name: 'guest'
    },
]

Roles must be registered in the config service.

@Injectable()
export class MyConfigService extends CrudConfigService {
    constructor(...) {
        ...
        this.addRoles(roles);
    }
}

Authorization

Eicrud's authorization checks role ability from root to branches:

• user.role : defineAbility + check against request.
  • user.role->inherits[0] : defineAbility + check against request.
    • inherit->inherits[0] : defineAbility + check against request.
    • inherit->inherits[1]
    • ...
  • user.role->inherits[1]
  • ...

The authorization stops going up the tree whenever a role passes the check, it also skips already-checked roles.

Note

This means cannot rules from inherited roles have no effect if the child role passes the authorization check.

Guest Role

Your application needs a guest role to define unauthenticated users' abilities. It is set the config service's constructor and defaults as 'guest'.
