@cerbos/http

Client library for interacting with the Cerbos policy decision point service over HTTP.

This is primarily intended for use in browsers, and requires fetch to be available globally. If you're targeting old browsers, you'll need to apply a polyfill.

You can use it in server-side Node.js applications, but the gRPC client might be more appropriate.

Prerequisites

• Cerbos 0.16+
• Node.js 18+
• fetch

Installation

$ npm install @cerbos/http

Example usage

import { HTTP } from "@cerbos/http";

const cerbos = new HTTP("http://localhost:3592");

await cerbos.isAllowed({
  principal: {
    id: "[email protected]",
    roles: ["USER"],
    attr: { tier: "PREMIUM" },
  },
  resource: {
    kind: "document",
    id: "1",
    attr: { owner: "[email protected]" },
  },
  action: "view",
}); // => true

For more details, see the HTTP class documentation.
