-------------------------------------------------------------------------------- 1 | 배치 처리에 대해서 알아보겠습니다. 2 | 배치 처리는 일정기간동안 데이터를 모아두었다가 대량의 데이터작업을 한번에 하는 것을 의미합니다. 또한 일정시간마다 주기적으로 실행 해야하는 작업을 말하기도합니다. 개발적으로 얘기한다면 작업을 스케줄링 하는 것을 의미합니다. 3 | 4 | 배치처리를 하는 가장 간단한 방법은 OS의 스케줄링 기능을 사용하는 것입니다. 윈도우에는 작업스케줄러라는 기능이 있고, 리눅스에는 크론탭이 있습니다. 5 | 리눅스의 크론탭만 간단하게 살펴보겠습니다. 6 | 7 | crontab -l 을 실행하면 현재 설정되어 있는 스케줄 잡이 보입니다. 8 | 수정은 crontab -e 로 들어가서 수정할 수 있습니다. 9 | 10 | 간단하게 우분투에서 한번 만들어보겠습니다. 11 | 12 | * * * * * echo "hello crontab $(date '+\%Y-\%m-\%d \%H:\%M:\%S')" >> /home/ubuntu/tmp/hello.txt -------------------------------------------------------------------------------- /backend-roadmap/deploy.md: -------------------------------------------------------------------------------- 1 | 배포라는 단어를 사용했지만, 실제로는 배포에 관련된 모든 업무를 뜻합니다. 2 | 아마도 괜찮은 회사라면 배포 도구를 사용해서 배포를 진행할 것입니다. 3 | 도구가 없다면, ftp를 사용해서 수작업으로 압축파일을 업로드 하고 있을 수도 있을 것입니다. 4 | 5 | 배포는 수작업으로 하기 보다는 도구를 사용하여 배포하는 것이 좋습니다. 반복적인 작업이지만, 매우 중요한 작업이기 때문에 실수하면 안되기 때문입니다. 6 | 7 | 손으로 하는 배포의 다음에는 스크립트를 사용해서 배포하는 방법이 있습니다. 다음으로는 스크립트를 실행해주는 도구를 사용하는 것입니다. 대표적으로 젠킨스, 서클CI등이 있습니다. 최근에는 깃헙액션이나, argoCD같은 프로그램들이 있을 수 있겠습니다. 8 | 9 | CI와 CD는 둘다 continuous integration, continuous deploy로 지속적으로 통합하고 지속적으로 배포한다는 한국말로는 약간이해하기 어려운 단어로 되어 있습니다. 10 | 11 | 쉽게 얘기하면 CI는 배포하기 전의 모든 단계를 자동화 하는 것을 의미합니다. 12 | 그러면 CD는 배포에 대한 것들을 자동화 하는 것을 말합니다. 13 | 배포도 그냥 하는 것이 아니라 서버여러대에 배포하는 경우에 몇대씩 나눠서 배포하는 롤링배포, 똑같은 수의 서버를 미리 띄워두고 게이트웨이만 변경하는 블루/그린배포, 특정 퍼센트의 서버에만 배포한다음 문제없으면 점차 배포를 확대하는 카나리 배포등 꽤나 복잡한 작업이 필요합니다. -------------------------------------------------------------------------------- /backend-roadmap/frameworks.md: -------------------------------------------------------------------------------- 1 | 프레임워크는 개발시에 필요한 것들을 미리 만들어줘서, 작업을 편하게 해줍니다. 2 | 개발시의 설정을 어떻게 하고, 코드는 어떻게 짜야하는지까지 제한을 하는 프레임워크가 있는반면, 3 | 최소한의 설정과 제약만을 가진 프레임워크도 있습니다. 4 | 제가 설명드리는 프레임워크는 모두 서버측에서 API를 만드는데 필요한 프레임워크입니다. 5 | 6 | Node.js에는 express가 대표적이지만, NestJS를 적어두었습니다. 7 | express는 최소한의 제약만을 주고 서드파티 라이브러리로 확장해나가는 프레임워크입니다. 8 | 반면 NestJS는 아키텍처구조를 어느정도 잡아줍니다. 9 | 나름 최신기능인 데코레이터를 사용하여 별도의 설정없이 라우터나 미들웨어들을 설정할 수 있게 해줍니다. 10 | 내부적으로 express와 fastify를 사용하고 있기 때문에, 기존의 express의 미들웨어를 사용할 수 있는 장점이 있습니다. 11 | 하지만, 아직까지는 상용 프로그램을 위한 프레임워크로 보자면 자바의 스프링에 비해서는 보안이나 인증, 인가, 배치 같은 부분에서 아쉬운 부분이 있습니다. 12 | 최근에 express가 발전이 미미하기 때문에 개인적으로는 NestJS가 조금더 발전 가능성이 있다고 생각하여 NestJS를 소개드렸습니다. 13 | 14 | 다음으로 자바진영의 스프링입니다. 스프링은 기업용 애플리케이션을 만드는데에 필요한 것들을 모두 갖추고 있는 프레임워크입니다. Spring webflux라고 불리는 리액티브 프로그래밍에서는 로그 추적이 조금 귀찮아진다던지, 멀티코어 활용이 어렵다던지 하는 아쉬운 부분이 있습니다만, 제가 사용해본 프레임워크중에는 기업용 애플리케이션을 작성하는데에는 가장 지원이 잘 되어 있는 프레임워크입니다. 다만 스프링은 태생자체가 기업용 애플리케이션을 작성을 돕는 프레임워크였기 때문에, 다른 프레임워크에 비해서 학습을 해야하는 것들이 상당히 많이 있습니다. 또한 같이 사용하는 jpa나 스프링 배치, 시큐리티등의 퀄리티도 굉장히 높은 반면 각각 책이 몇권씩 있을 정도로 학습량이 많습니다. 스프링은 참 좋지만, 자바가 발전이 더딘편이며 행사코드가 참 많습니다. 다만 이 부분은 최근에 코틀린이 나와서 어느정도 해소되었다고 생각합니다. 국내에서는 취업에 유리한 부분도 분명히 있습니다. 큰회사에서는 대부분 스프링을 사용하니까요. 많은 사람들이 사용하고 있기 때문에 커뮤니티도 잘 되어 있어서 모르는게 나오거나 문제 발생시에 물어볼 사람이 많이 있다는 것도 장점입니다. 15 | 16 | FastAPI는 파이썬 커뮤니티에서 최근에 인기가 있는 프레임워크입니다. 파이썬에는 장고와 플라스크라는 매우 유명한 프레임워크가 있습니다만, API만 작성하는 용도라면 앞으로는 FastAPI를 배워두는 것이 좋을 것 같다고 생각하여 소개드립니다. 최소한의 설정과 제약을 주는 프레임워크로, 플라스크와 비슷한 컨셉의 프레임워크입니다. 스프링과 비슷하게 의존 성주입을 사용합니다. Pydantic기반의 유효성 검증이 좋습니다. 스웨거 기반의 문서 자동화도 굉장히 잘되어 있습니다. async/await기반의 동시성을 도입하여 성능이 좋고, 빠르고, 배우기 쉽습니다. 기업용 애플리케이션을 작성하기 위해서는 스프링에 비해서는 직접 해야하하는 일이 많습니다. 17 | 18 | 여기까지 프레임워크에 대해서 설명드렸습니다. 제가 설명 드린 것 이외에도 많은 프레임워크가 있습니다. 19 | 백엔드 개발을 하기 위해서는 프레임워크 하나 정도는 깊게 공부를 해두는 것이 좋습니다. 20 | 21 | -------------------------------------------------------------------------------- /backend-roadmap/git-github.md: -------------------------------------------------------------------------------- 1 | JSON은 JavaScript Object Notation의 약자로 데이터를 표현하는 방법을 말합니다. 자바스크립트의 객체 표현법과 유사하게 생겼고, 직관적이고 단순한 구조입니다. 2 | 3 | 4 | -------------------------------------------------------------------------------- /backend-roadmap/images/2023-02-20-19-12-33.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/wapj/jsbackend/f2b425ec80e047136f9cbf6debffd2715f378f40/backend-roadmap/images/2023-02-20-19-12-33.png -------------------------------------------------------------------------------- /backend-roadmap/images/2023-02-20-19-31-16.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/wapj/jsbackend/f2b425ec80e047136f9cbf6debffd2715f378f40/backend-roadmap/images/2023-02-20-19-31-16.png -------------------------------------------------------------------------------- /backend-roadmap/introduce.md: -------------------------------------------------------------------------------- 1 | 2 | ``` 3 | 안녕하세요. 4 | 저는 2008년부터 개발을 시작해서 만으로 15년 넘게 개발을 하고 있는 백엔드 개발자입니다. 5 | 저의 경험을 살려서 백엔드 개발자를 희망하시는분들에게 조금이나마 도움이 되고자 6 | 백엔드 개발자 로드맵 영상을 찍게 되었습니다. 모쪼록 도움이 되셨으면 좋겠습니다. 7 | 8 | 우선 백엔드 개발자가 되기 위해 알아야 하는 것들을 살펴보겠습니다. 9 | ``` 10 | 11 | 12 | [https://roadmap.sh/backend](https://roadmap.sh/backend) 에 13 | 가면 다른 사람들이 백엔드 개발자 로드맵으로 만들어 놓은 것을 볼 수 있습니다. 14 | 15 | 인터넷, 깃, 데이터베이스, 캐시, CI/CD, 디자인 & 개발 원칙, 웹소켓, 보안 관련등등 굉장히 다양하게 나와있습니다. 16 | 저 표와는 조금 다르지만, 저는 초보 개발자가 알아야 할 로드맵으로 다시 구성해보았습니다. 17 | 초보 개발자는 도움을 조금 받으면 자기에게 맡겨진 일을 해결 할 수 있는 개발자라고 생각했습니다. 18 | 19 | 우선 제가 정리해서 보여드리는 것들을 먼저 보시고 20 | 부족한 부분들은 해당 웹사이트 혹은 협업에서 필요한 부분들을 골라서 학습을 하시는 것을 추천드립니다. 21 | 22 | 인터넷, 버전 컨트롤, 개발 언어, 데이터 표현법, 리눅스 명령어, 웹서버, 인증과 인가, 프레임워크, 데이터베이스, API, 배치처리, 배포에 대하여 각각의 영상으로 다시 찾아 봽겠습니다. 23 | 감사합니다. -------------------------------------------------------------------------------- /backend-roadmap/what-is-internet.md: -------------------------------------------------------------------------------- 1 | ## 인터넷은 무엇일까요? 2 | 인터넷은 전세계의 컴퓨터들이 서로 정보를 주고 받을 수 있도록 한 거대한 네트워크입니다. 네트워크란 Net와 Work의 합성어로 여러대의 컴퓨터가 서로 통신을 할 수 있게 하는 것입니다. 네트워크는 어디에나 있습니다. 유선으로 연결된 네트워크, 무선으로 연결된 네트워크, 공개가 되어 있는 네트워크, 사설 네트워크, 학교, 병원, 회사, 기관, 정부등 온 세상이 네트워크 천지 입니다. 이런 네트워크들의 집합체가 바로 인터넷입니다. 그래서 네트워크들의 네트워크를 인터넷이라 부르기도 합니다. 3 | 4 | ## 인터넷은 어떻게 동작할까요? 5 | 컴퓨터 두 대를 서로 연결해서 통신을 주고 받을 수 있게 한다고 가정해봅시다. 6 | 7 | 컴퓨터가 두 대가 있고 서로 통신을 하고 싶다고 가정합시다. 인터넷은 TCP/IP라는 프로토콜로 통신을 한다고 했습니다. TCP/IP프로토콜에서 두 대의 컴퓨터는 각각 고유한 주소인 IP(Internet Protocol)을 가집니다. IP는 ping 명령어로 쉽게 확인할 수 있습니다. 터미널에서 ping google.com 을 하면 구글의 IP주소 중 하나를 확인 할 수 있습니다. 142.251.42.142을 주소창에 치면 구글에 접속할 수 있습니다. 그런데 IP주소는 외우기가 어렵기 때문에 사람이 기억하기 쉽게 만든 것이 바로 DNS입니다. 일종의 전화번호부라고 할 수 있습니다. 전화번호부에서 사람이름을 찾으면 전화번호를 외우지 않아도 되듯이, 도메인을 알고 있으면 IP를 외우지 않아도 됩니다. 8 | 9 | ![](images/2023-02-20-19-31-16.png) 10 | 11 | https://www.youtube.com/watch?v=7_LPdttKXPc 12 | 13 | https://developer.mozilla.org/ko/docs/Learn/Common_questions/Web_mechanics/How_does_the_Internet_work 14 | 15 | http://web.stanford.edu/class/msande91si/www-spr04/readings/week1/InternetWhitepaper.htm 16 | 17 | 18 | https://roadmap.sh/guides/what-is-internet 19 | 20 | https://velog.io/@jiseung/01-how-does-the-internet-work 21 | 22 | 23 | https://www.youtube.com/watch?v=Dxcc6ycZ73M 24 | 25 | http://www.tcpschool.com/webbasic/intro#:~:text=%EC%9D%B8%ED%84%B0%EB%84%B7(Internet)%EC%9D%98%20%EA%B0%9C%EB%85%90,%EC%BB%B4%ED%93%A8%ED%84%B0%20%ED%86%B5%EC%8B%A0%EB%A7%9D%EC%9D%84%20%EC%9D%98%EB%AF%B8%ED%95%A9%EB%8B%88%EB%8B%A4. 26 | 27 | 종립님의 인정을 받다니... 뿌듯합니다. -------------------------------------------------------------------------------- /bookmark-app/.eslintrc.js: -------------------------------------------------------------------------------- 1 | module.exports = { 2 | parser: '@typescript-eslint/parser', 3 | parserOptions: { 4 | project: 'tsconfig.json', 5 | tsconfigRootDir: __dirname, 6 | sourceType: 'module', 7 | }, 8 | plugins: ['@typescript-eslint/eslint-plugin'], 9 | extends: [ 10 | 'plugin:@typescript-eslint/recommended', 11 | 'plugin:prettier/recommended', 12 | ], 13 | root: true, 14 | env: { 15 | node: true, 16 | jest: true, 17 | }, 18 | ignorePatterns: ['.eslintrc.js'], 19 | rules: { 20 | '@typescript-eslint/interface-name-prefix': 'off', 21 | '@typescript-eslint/explicit-function-return-type': 'off', 22 | '@typescript-eslint/explicit-module-boundary-types': 'off', 23 | '@typescript-eslint/no-explicit-any': 'off', 24 | }, 25 | };
