oso
What is oso?
oso is an open source policy engine for authorization that’s embedded in your application. It provides a declarative policy language for expressing authorization logic. You define this logic separately from the rest of your application code, but it executes inside the application and can call directly into it. oso ships as a library with a built-in debugger and REPL.
Getting started
To get up and running with oso, check out the Getting Started guide in the oso documentation.
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+
- Python: 3.6+
- Ruby: 2.4+
- Node.js: 10.14.2+
