ランタイムに縛られないTypeScriptアプリケーション

Application、Contract、DI、Taskを一つのGraphとして構築

一つのApplication Model

Application、Contract、DI、Taskを一つのGraphで表現します

Contract

Protocolと型を定義

Implementation

Contractと実装を分離

Module & DI

Moduleで依存性を構成

Task

JobやCLIも型安全に定義

Application Graph

依存関係をすべて可視化

ApplicationとRuntimeを分離

コードは変えずに、Runtimeだけを切り替えられます

const application = defineApplication({

　modules: [UsersModule(), HealthModule()],

})

export default application

Runtimes

Application Graph

Loutre Graph APIで、依存関係と構成を可視化

loutre graph modules --entry src/app.ts

AppModule [module:1]

　description: HTTP Application entry module

　imports: (none)

Application

UsersModule

HealthModule

Contract (GET /users)

Contract (GET /health)
