Description

Oso is a batteries-included library for building authorization in your application.

Oso gives you a mental model and an authorization system – a set of APIs built on top of a declarative policy language called Polar, plus a debugger and REPL – to define who can do what in your application. You can express common concepts from “users can see their own data” and role-based access control, to others like multi-tenancy, organizations and teams, hierarchies and relationships.

What is Oso?

Oso is a batteries-included framework for building authorization in your application.

With Oso, you can:

  • Model: Set up common permissions patterns like role-based access control (RBAC) and relationships using Oso’s built-in primitives. Extend them however you need with Oso’s declarative policy language, Polar.
  • Filter: Go beyond yes/no authorization questions. Implement authorization over collections too - e.g., “Show me only the records that Juno can see.”
  • Test: Write unit tests over your authorization logic now that you have a single interface for it. Use the Oso debugger or REPL to track down unexpected behavior.

Oso offers libraries for Node.js, Python, Go, Rust, Ruby, and Java.

Development

Core

Oso's Rust core is developed against Rust's latest stable release.

Language libraries

Oso's language libraries can be developed without touching the Rust core, but you will still need the Rust stable toolchain installed in order to build the core.

To build the WebAssembly core for the Node.js library, you will need to have wasm-pack installed and available on your system PATH.

Language requirements

To work on a language library, you will need to meet the following version requirements:

  • Java: 10+
    • Maven: 3.6+
  • Node.js: 12.20.0+
    • Yarn 1.22+
  • Python: 3.6+
  • Ruby: 2.4+
    • Bundler 2.1.4+
  • Rust: 1.46+
  • Go: 1.12+
