nestja for bff (example)

Example: Nest.js for BFF

기본 파일	용도
app.controller.spec.ts	컨트롤러 단위 테스트용
app.controller.ts	기본 컨트롤러 @Controller
app.module.ts	root module, 스프링으로 치면 @Configuraion인가?
app.service.ts	기본 서비스 @Component
main.js	Nest.js 애플리케이션 인스턴스를 생성하는 메인

적용해볼 것

• 환경변수를 주입받아 코드에서 사용하기
• 컨트롤러로 요청을 처리하기
• OpenApi Generator로 서버 Client 생성하기
• 서버 Client를 비동기로 사용하기
• inbound, outbound 로깅

$ openapi-generator-cli generate -i ./apispec/delay-api.yaml -g typescript-axios -o './src/client'
