LinFx

一個基於 .NET Core 2.0 開發的簡單易用的快速開發框架，遵循領域驅動設計（DDD）規範約束，提供實現事件驅動、事件回溯、響應式等特性的基礎設施。讓開發者享受到正真意義的面向對象設計模式來帶的美感。

LinFx.Extensions

Caching、DapperExtensions、Elasticsearch、EventBus、Metrics、Mongo、RabbitMQ

特性

1. 領域驅動設計（DDD）
2. 事件驅動架構 (EDA)
3. 事件回溯 （ES）
4. 最終一致性 （Eventually Consistent）
5. 框架中每個組件都有基礎實現，最簡單時只需一個核心類庫就能跑起來
6. 遵循埠與適配器模式，框架組件適配多種第三方組件實現，可從單體架構到面向服務架構按需擴展

設計規範

1. 儘量使用.NET Standard和官方提供的類庫，第三方類庫設計成組件利用DI來按需組合。

安裝Nuget包

Samples

public void ConfigureServices(IServiceCollection services)
{
    services.AddLinFx()
        .AddDistributedRedisCache(options =>
        {
            options.Configuration = configuration.GetConnectionString("ReidsConnection");
        })
        .AddMongoDBContext(options =>
        {
            options.Name = "default";
            options.Configuration = configuration.GetConnectionString("MongoConnection");
        })
        .AddElasticsearch(options =>
        {
            options.DefaultIndex = "default";
            options.Host = "http://10.0.1.112:9200";
        });
