How to add Fine-Grained Authorization (FGA) to an Express + Typescript API using the OpenFGA Javascript and Node.js SDK.

Auth0's platform is a  identity management solution, offering insights into authentication, authorization, and user management for web and mobile applications. Through articles, tutorials, and documentation, Auth0 offers insights into securing applications with modern identity protocols like OAuth and OpenID Connect.

OpenFGA, an open-source system designed by Okta and adopted by the CNCF for Relationship-Based Access Control (ReBAC), is used to secure a Node.js API with Auth0. The guide demonstrates setting up API authorization with Auth0, initializing an authorization model in OpenFGA, and incorporating Fine-Grained Authorization (FGA) using OpenFGA's Node.js SDK. Detailed steps involve setting up environments, creating middleware for token validation and permission checks, and running the API to manage document permissions effectively.
