Installation

npm install @tenxyte/core
# or
yarn add @tenxyte/core
# or
pnpm add @tenxyte/core

Quick Start

import { TenxyteClient } from '@tenxyte/core';

const tx = new TenxyteClient({
    baseUrl: 'https://api.my-backend.com',
    headers: { 'X-Access-Key': 'your-public-app-key' },
});

// Login
const tokens = await tx.auth.loginWithEmail({
    email: '[e-mail]',
    password: 'secure_password!',
    device_info: '',
});

// Check authentication state
const isLoggedIn = await tx.isAuthenticated();
const user = await tx.getCurrentUser();

Important: Never expose X-Access-Secret in frontend bundles. Use it exclusively server-side.

Configuration

The TenxyteClient accepts a single configuration object. Only baseUrl is required.

const tx = new TenxyteClient({
    // Required
    baseUrl: 'https://api.my-service.com',

    // Optional — extra headers for every request
    headers: { 'X-Access-Key': 'pkg_abc123' },

    // Optional — token storage backend (default: MemoryStorage)
    // Use LocalStorageAdapter for browser persistence
    storage: new LocalStorageAdapter(),

    // Optional — auto-refresh 401s silently (default: true)
    autoRefresh: true,

    // Optional — auto-inject device fingerprint into auth requests (default: true)
    autoDeviceInfo: true,

    // Optional — global request timeout in ms (default: undefined)
    timeoutMs: 10_000,

    // Optional — retry config for 429/5xx with exponential backoff
    retryConfig: { maxRetries: 3, baseDelayMs: 500 },

    // Optional — callback when session cannot be recovered
    onSessionExpired: () => router.push('/login'),

    // Optional — pluggable logger (default: silent no-op)
    logger: console,
    logLevel: 'debug', // 'silent' | 'error' | 'warn' | 'debug'

    // Optional — override auto-detected device info
    deviceInfoOverride: { app_name: 'MyApp', app_version: '2.0.0' },
});

Modules

    completion_tokens: 420,
});

// Traceability
tx.ai.setTraceId('trace-1234'); // adds X-Prompt-Trace-ID header
tx.ai.clearTraceId();

Applications (tx.applications)

const apps = await tx.applications.listApplications();
const app = await tx.applications.createApplication({
    name: 'My API Client',
    description: 'Backend service',
});
const detail = await tx.applications.getApplication('app-id');

const log = await tx.admin.getAuditLog('log-id');

// Login attempts
const attempts = await tx.admin.listLoginAttempts({ user_id: 'uid' });

// Blacklisted tokens
const blacklisted = await tx.admin.listBlacklistedTokens();
await tx.admin.cleanupBlacklistedTokens();

// Refresh tokens
const refreshTokens = await tx.admin.listRefreshTokens({ user_id: 'uid' });
await tx.admin.revokeRefreshToken('token-id');

GDPR (tx.gdpr)

const auth = await tx.dashboard.getAuthStats();
const security = await tx.dashboard.getSecurityStats();
const gdpr = await tx.dashboard.getGdprStats();
const orgStats = await tx.dashboard.getOrganizationStats('acme-corp');

SDK Events

The SDK emits events via a built-in EventEmitter. Use tx.on(), tx.once(), and tx.off() to subscribe.

Event	Payload	When
session:expired	void	Refresh token expired/revoked, session unrecoverable
token:refreshed	{ accessToken: string }	Access token silently rotated via auto-refresh
token:stored	{ accessToken: string; refreshToken?: string }	Tokens persisted after login, register, or refresh
agent:awaiting_approval	{ action: unknown }	AI agent action requires human confirmation (HTTP 202)
error	{ error: unknown }	Unrecoverable SDK error not tied to a specific call

// React to session expiry
tx.on('session:expired', () => {
    router.push('/login');
});

// Track token refreshes
tx.on('token:refreshed', ({ accessToken }) => {
    console.log('Token refreshed silently');
});

// HITL notification
tx.on('agent:awaiting_approval', ({ action }) => {
    showApprovalDialog(action);
});

High-Level Helpers

// Check if user is authenticated (synchronous JWT expiry check)
const isLoggedIn = await tx.isAuthenticated();

// Get the raw access token
const token = await tx.getAccessToken();

// Get decoded JWT payload (no network call)
const user = await tx.getCurrentUser();

// Check token expiry
const expired = await tx.isTokenExpired();

// Get full SDK state snapshot (for framework wrappers)
const state = await tx.getState();
// { isAuthenticated, user, accessToken, activeOrg, isAgentMode }

Migration Guide: v0.9 → v1.0

Breaking Changes

• Constructor signature changed — The client now accepts a TenxyteClientConfig object:

  // Before (v0.9)
  const tx = new TenxyteClient({ baseUrl: '...', headers: { ... } });
  
  // After (v1.0) — same, but new options available
  const tx = new TenxyteClient({
      baseUrl: '...',
      headers: { ... },
      autoRefresh: true,    // NEW
      autoDeviceInfo: true, // NEW
      retryConfig: { ... }, // NEW
  });
  

• loginWithEmail now requires device_info:

  // Before (v0.9)
  await tx.auth.loginWithEmail({ email, password });
  
  // After (v1.0)
  await tx.auth.loginWithEmail({ email, password, device_info: '' });
  

• requestMagicLink now requires validation_url:

  // Before
  await tx.auth.requestMagicLink({ email });
  
  // After
  await tx.auth.requestMagicLink({ email, validation_url: 'https://...' });
  

• Auto-session management — Tokens are now automatically stored and the Authorization header is automatically injected. You no longer need to manage this manually.

• New modules added — tx.applications, tx.admin, tx.gdpr, tx.dashboard are now available.

• register() return type changed — Now returns RegisterResponse (may include tokens if auto-login is enabled).

New Features in v1.0

• Auto-refresh interceptor (silent 401 → refresh → retry)
• Configurable retry with exponential backoff (429/5xx)
• Device info auto-injection
• Pluggable logger with log levels
• High-level helpers (isAuthenticated, getCurrentUser, isTokenExpired)
• getState() for framework wrapper integration
• EventEmitter for reactive state (session:expired, token:refreshed, etc.)
