@marxlnfcs/nest-rbac-auth v1.0.6

Warning This library is for experimentation and may contain some bugs that I will remove from time to time. With this library I'm learning how dependency injection works and how to build such libraries according to "best practice".

So please use this library with caution.

Information If you want to use the old RBAC system, please use v0.1.4 because v1.X.X uses a new system with a dot notation (e.g.: foo.bar.*)

Installation

npm i @marxlnfcs/nest-rbac-auth

Usage

Import Module

import { RbacModule } from '@marxlnfcs/nest-rbac-auth';

@Module({
    imports: [
        RbacModule.forRoot()
    ]
})
export class AppModule {}

Controller

import { RbacSection, RbacRequires } from '@marxlnfcs/nest-rbac-auth';

@Controller('/users')
@RbacSection('access', 'Access Management')
@RbacSection('user', 'User')
export class UserController {

    @Get()
    // @RbacRequires(['list'], 'Can list users')
    // @RbacRequiresList('Can list users')
    @RbacRequires('list', 'Can list users')
    getUsers(){ ... }

    @Get('/:userId')
    // @RbacRequires(['get'], 'Can retrieve a user')
    // @RbacRequiresGet('Can retrieve a user')
    @RbacRequires('GET', 'Can retrieve a user')
    getUser(...){ ... }

    @Post('/')
    // @RbacRequires(['create'], 'Can create a user')
    // @RbacRequiresCreate('Can create a user')
    @RbacRequires('create', 'Can create a user')
    createUser(...){ ... }

    @Put('/:userId')
    // @RbacRequires(['update'], 'Can update a user')
    // @RbacRequiresUpdate('Can update a user')
    @RbacRequires('update', 'Can update a user')
    updateUser(...){ ... }

    @Delete('/:userId')
    // @RbacRequires(['delete'], 'Can delete a user')
    // @RbacRequiresDelete('Can delete a user')
    @RbacRequires('delete', 'Can delete a user')
    deleteUser(...){ ... }

    @Post('/action')
    // @RbacRequires(['custom'], 'Can do <custom> action')
    @RbacRequires('custom', 'Can do <custom> action')
    customAction(...){ ... }
    
}

@Controller('/groups')
@RbacSection('access', 'Access Management')
@RbacSection('group', 'Group')
export class GroupController {
    ...
}

Validate Bindings / Permissions with the BuildIn AuthGuard

import { RbacService, RbacGuard, IRbacValidateRequest } from '@marxlnfcs/nest-rbac-auth';

@Injectable()
export class RoleGuard extends RbacGuard() {
    constructor(
        private rbacService: RbacService,
    ){}
    
    validate(request: IRbacValidateRequest): boolean | Promise<boolean> | Observable<boolean> {
        return this.validateRequest(request, ['*', '!*.create', '!*.update']);
    }
}

Skip validation for certain routes

import { RbacSection, RbacRequiresList } from '@marxlnfcs/nest-rbac-auth';

@Controller('/users')
@RbacSection('access', 'Access Management')
@RbacSection('user', 'User')
export class UserController {

    @Get()
    @RbacRequiresList({ skipValidation: true })
    getUsers(){ ... }

}
