openfga/js-sdk

The OpenFGA JavaScript SDK is a client library for Node.js and JavaScript that wraps the OpenFGA API and provides TypeScript typings.

OpenFGA is a fine-grained authorization system inspired by Google's Zanzibar paper, designed to help developers model and integrate permission layers into applications. The SDK provides a typed interface to OpenFGA's authorization service, enabling developers to work with stores, authorization models, relationship tuples, and permission queries through a JavaScript client rather than making raw HTTP calls.

Developers building applications that need fine-grained access control should consider this SDK if they are already using OpenFGA or evaluating it as their authorization solution. The tool is particularly suited for Node.js backends and JavaScript applications that require programmatic access to OpenFGA's permission checking, relationship management, and authorization model operations. The SDK includes support for custom headers, retries, OpenTelemetry integration, and batch operations like batch checking permissions.

The project is autogenerated from the OpenFGA API definition, meaning the SDK stays synchronized with the service's capabilities through an automated process. Development activity shows consistent maintenance with regular updates to keep the SDK aligned with API changes. The project maintains documentation for supported Node.js versions and provides clear guidance on initialization and common usage patterns.
