​
Overview

The Wacht TypeScript SDK provides a comprehensive, type-safe client for all Wacht platform APIs. It is designed for both frontend and backend applications, offering excellent developer experience and flexibility. Additionally, it provides framework-specific authentication and authorization middlewares for popular environments like Node.js (Express-style) and Hono.

​
Key Features

​
Complete API Coverage

  • All Backend Endpoints - Full coverage of Wacht platform APIs
  • Type-Safe Models - Strongly typed request/response structures
  • Asynchronous Operations - Modern asynchronous patterns with Promises
  • Axios-based HTTP Client - Robust and flexible HTTP client

​
Authentication & Authorization

  • JWT Validation - Core JWT token validation logic within the main SDK
  • Framework-Specific Middlewares - Dedicated middleware packages for Node.js (Express-style) and Hono for seamless integration.
  • Permission System - Fine-grained permission checks at route and handler level (via middlewares)

​
Developer Experience

  • Easy Initialization - Simple SDK initialization
  • Environment Configuration - Easy setup via environment variables
  • Comprehensive Error Handling - Detailed error types with context

​
Architecture

The SDK follows a modular architecture with clear separation of concerns: 
wacht-ts
├── API Modules (Users, Organizations, Workspaces, etc.)
├── Core Authentication Logic (JWT validation, types)
├── Global Client Configuration
└── Error Handling

wacht-middleware-node
├── Node.js (Express-style) Authentication Middleware
└── Node.js (Express-style) Authorization Middleware

wacht-middleware-hono
├── Hono Authentication Middleware
└── Hono Authorization Middleware

​
Use Cases

​
Frontend Applications

Build secure frontend applications that interact with the Wacht platform:
  • User authentication and session management
  • Accessing user-specific data
  • Integrating with Wacht APIs for various features

​
Backend Services

Build secure backend services that interact with the Wacht platform:
  • User management systems
  • Organization and workspace administration
  • AI agent orchestration
  • Analytics and reporting services

​
API Gateways

Create API gateways with built-in authentication:
  • Validate JWT tokens from Wacht
  • Enforce permissions at the gateway level
  • Route requests based on user context
  • Multi-tenant request routing

​
Microservices

Build microservices that integrate with Wacht:
  • Service-to-service authentication
  • Permission-based access control
  • Async task processing
  • Event-driven architectures

​
Getting Started

The SDK is designed to get you up and running quickly:
  1. Install the wacht-ts package and the relevant middleware package (e.g., wacht-middleware-node or wacht-middleware-hono).
  2. Set environment variables for API key and host.
  3. Initialize the SDK in your application.
  4. Start making API calls or integrate the authentication/authorization middlewares.
