Xians.Lib

A robust .NET library for establishing HTTP and Temporal server connections with built-in resilience, retry logic, and health monitoring.

Releases

# Define the version
export VERSION=1.3.7 # or 1.3.7-beta for pre-release

# Create and push a version tag
git tag -a v$VERSION -m "Release v$VERSION"
git push origin v$VERSION

Installation

dotnet add package Xians.Lib

⚠️ Important: API Key Format

The API key must be a Base64-encoded X.509 certificate, not a simple string.

The certificate must contain:

• Organization (O=) field with your tenant ID
• Common Name (CN=) field with your user ID

Example:

# ❌ WRONG - Simple string will fail
API_KEY=my-api-key-123

# ✅ CORRECT - Base64-encoded certificate
API_KEY=MIIDXTCCAkWgAwIBAgIJAKL5g3aN3dqKMA0GCSqGSIb3DQEBCwUA...

See Authentication Guide for details.

Quick Start

Recommended: Initialize from Environment (Fetches Temporal config from server):

using Xians.Lib.Common;

// Set environment variables:
// SERVER_URL=https://api.example.com
// API_KEY=your-api-key

var (httpService, temporalService) = await ServiceFactory.CreateServicesFromEnvironmentAsync();

// Use HTTP service
var response = await httpService.GetWithRetryAsync("/api/data");

// Use Temporal service (config fetched from server)
var temporalClient = await temporalService.GetClientAsync();

Alternative: Direct initialization:

using Xians.Lib.Common;

var (httpService, temporalService) = await ServiceFactory.CreateServicesFromServerAsync(
    serverUrl: "https://api.example.com",
    apiKey: "your-api-key"
);
// Temporal settings automatically fetched from: GET /api/agent/settings/flowserver

Manual Configuration (Advanced):

using Xians.Lib.Configuration;
using Xians.Lib.Common;

// HTTP only
var httpConfig = new ServerConfiguration
{
    ServerUrl = "https://api.example.com",
    ApiKey = "your-api-key"
};
using var httpService = ServiceFactory.CreateHttpClientService(httpConfig);

// Temporal only (manual config)
var temporalConfig = new TemporalConfiguration
{
    ServerUrl = "localhost:7233",
    Namespace = "default"
};
using var temporalService = ServiceFactory.CreateTemporalClientService(temporalConfig);
