ts-clean-arch

試著將自己理解的clean architecture 跟 DDD (Domain Driven Design) 用 Nodejs 做出簡單的開發架構。

主要有:

  • 不被 express 等 External Service 耦合影響。
  • Domain Layer, Application Layer, Infrastructure Layer 分層
  • 對外 External Service 另外分一層,先用Express。

Technologies 要做的部分


Install

npm init
npm install typescript @types/node
npx tsc --init
npm install ts-node nodemon --save-dev

IoC

npm install inversify reflect-metadata --save

TypeScript Interface 在反射("reflect-metadata")時,無法使用非實體的interface去反射,所以在inversify需要定義:

// default.app.ts
@injectable()
export class AppUseCase implements IAppUseCase {
    async getAppName(): Promise<AppName> {
        const result = new AppName();

// app.route.ts
@injectable()
export class AppRoute {

    private _appUseCase: IAppUseCase;
    constructor(
        @inject(Symbol.for('IAppUseCase')) appUseCase: IAppUseCase,
    ) {
        this._appUseCase = appUseCase;

// IoC
// DI-container.ts
container.bind<IAppUseCase>(Symbol.for('IAppUseCase')).to(AppUseCase);

webpack

npm i --save-dev webpack webpack-cli webpack-node-externals start-server-nestjs-webpack-plugin clean-webpack-plugin
npm i --save-dev ts-loader

tsoa

npm i tsoa swagger-ui-express
npm i --save-dev @types/swagger-ui-express

InversifyJS 無法用webpack hmr

typeorm

npm install @nestjs/typeorm typeorm --save
npm install reflect-metadata --save
