EmpowerID Identity Fabric SDK – Python & React packages
EmpowerID Identity Fabric provides a secure‐by‐default toolkit for building apps on top of the EmpowerID Identity Fabric Platform. The SDK is split into two families:
| Package | Runtime | Purpose |
|---|---|---|
empowernow-common |
Python 3.10 – 3.12 | Shared cryptography, OAuth helpers, AuthZEN PDP client, Redis/metrics utilities. |
@empowernow/bff-auth-react |
React 18 | Hooks & components for the Backend-for-Frontend (BFF) cookie-based auth model. |
@empowernow/ui |
React 18 | Headless UI-component library used by all EmpowerID Identity Fabric SPAs. (Depends on either @empowernow/bff-auth-react or the legacy shim @empowernow/react.) |
Why no browser-side OAuth client? EmpowerID Identity Fabric moved to a BFF architecture to comply with FAPI 2.0 Baseline / Advanced and to keep tokens out of the browser. The legacy
@empowernow/reactlibrary now acts as a thin re-export of@empowernow/bff-auth-reactfor backward compatibility. It no longer handles tokens.
Installation
Python (server-side services)
pip install "empowernow-common>=2.3,<3"
Optional extras:
empowernow-common[fips]– Use when running under an OpenSSL FIPS provider.empowernow-common[redis],empowernow-common[kafka], etc. – Feature-scoped extras, see pyproject.toml.
React (front-end SPAs)
npm install @empowernow/bff-auth-react @empowernow/ui
If you still have code importing @empowernow/react, update it at your own pace – the alias re-exports the new package so nothing breaks at runtime.
Quick start
Using the Python OAuthClient
from empowernow_common.oauth import OAuthClient
oauth = OAuthClient(
issuer="https://idp.example.com",
client_id="python-client",
client_secret="…", # confidential client
redirect_uri="https://bff.example.com/auth/callback",
scopes=["openid", "profile"]
)
auth_url = oauth.create_authorization_url(state="xyz")
print("Open browser to", auth_url)
React – wrap your SPA in the AuthProvider
import { AuthProvider } from '@empowernow/bff-auth-react';
import { createRoot } from 'react-dom/client';
import App from './App';
createRoot(document.getElementById('root')!).render(
<AuthProvider baseUrl={import.meta.env.VITE_BFF_BASE_URL}>
<App />
</AuthProvider>
);
useAuth() gives you isAuthenticated, user, session and convenience helpers like login() and logout(); apiClient is a fetch wrapper that automatically adds CSRF headers and credentials:"include".
Security & Compliance
- FAPI 2.0 ready – private-key-JWT, PAR, JARM, DPoP and SameSite cookie model supported at the BFF layer.
- FIPS option – When the host OpenSSL runs in FIPS 140-3 mode,
empowernow-commoncan validate algorithms at start-up and periodically (opt-in via envFIPS_CONTINUOUS_VALIDATION=1). - No browser tokens – SPAs never see access- or refresh-tokens; they use HttpOnly cookies issued by the BFF.
- Structured logging & Prometheus metrics built in.
