Privileged is an isomorphic authorization library for restricting resources by action, subjct and fields. It's designed to be incrementally adoptable and can easily scale between a simple claim based and fully featured subject and action based authorization. It makes it easy to manage and share permissions across UI components, API services, and database queries.

Inspired by CASL

Coverage Status



  • Versatile An incrementally adoptable and can easily scale between a simple claim based and fully featured subject and attribute based authorization.
  • Isomorphic Can be used on frontend and backend and complementary packages make integration with Frontend and Backend effortless
  • Declarative Thanks to declarative rules, you can serialize and share permissions between UI and API or microservices


Privileged operates on rules for what a user can actually do in the application. A rule itself depends on the 3 parameters:

  1. Action Describes what user can actually do in the app. User action is a word (usually a verb) which depends on the business logic (e.g., update, read). Very often it will be a list of words from CRUD - create, read, update and delete.
  2. Subject The subject which you want to check user action on. Usually this is a business (or domain) entity name (e.g., Subscription, Post, User).
  3. Fields Can be used to restrict user action only to matched subject's fields (e.g., to allow moderator to update published field of Post but not update description or title)


Using builder to create rules

var context = new PrivilegeBuilder()
    .Allow("test", PrivilegeSubjects.All)
    .Allow(PrivilegeActions.All, "Post")
    .Forbid("publish", "Post")

context.Allowed("read", "Post").Should().BeTrue();
context.Allowed("update", "Post").Should().BeTrue();
context.Allowed("archive", "Post").Should().BeTrue();
context.Allowed("read", "User").Should().BeFalse();
context.Allowed("delete", "Post").Should().BeTrue();
context.Allowed("publish", "Post").Should().BeFalse();
context.Allowed("test", "User").Should().BeTrue();
context.Allowed("test", "Post").Should().BeTrue();

Using fields

var context = new PrivilegeBuilder()
    .Allow("read", "Post", ["title", "id"])
    .Allow("read", "User")

context.Allowed("read", "Post").Should().BeTrue();
context.Allowed("read", "Post", "id").Should().BeTrue();
context.Allowed("read", "Post", "title").Should().BeTrue();
context.Allowed("read", "Post", "ssn").Should().BeFalse();

context.Allowed("read", "User").Should().BeTrue();
context.Allowed("read", "User", "id").Should().BeTrue();
