반응형
typescript 그대로는 브라우저가 읽지 못하기 때문에 js로 변환이 되어야 한다.
변환될 때 어떤 규칙에 따라서 할 것인지를 설정하기 위한 파일이 tsconfig.json이며, package.json과 같은 root에 위치한다.
기본적으로는 아래처럼 작성한다.(intellij 기준 자동으로 아래처럼 채워진다)
target은 어떤 버젼의 js로 변환할지 결정한다. 더 신버젼을 원할 경우 es2016, esnext 등으로 기입한다.
module은 import export 규칙을 결정한다. commonjs는 require문법, es2016, esnext는 import 문법
브라우저 호환성을 위한다면 아래 기본형태가 낫겠고,
일렉트론 같이 특정 브라우저 한정으로 돌아가는 애플리케이션이라면 가능한 최신 문법을 사용함이 나을 것으로 생각된다.
{
"compilerOptions": {
"module": "commonjs", // import 를 require문법으로 사용
"target": "es5", // es5에 맞춰 js로 변경
"sourceMap": true // js의 .map 파일 생성
},
"exclude": [
"node_modules"
]
}

"noFallthroughCasesInSwitch": true, //switch문 이상하면 에러내기
}
}
설정할 수 있는 compilerOptions의 모든 내용은 아래와 같다.
필요할 경우 커스터마이징 하면 되겠지만, 너무 많기 때문에 보통은 공통적으로 사용할 것만 사용하는게 정신건강에 나아보인다.
