 프론트엔드 생존코스 1주차 과제
+
+## 개발 환경
+
+### 1. 시작하기
+
+```sh
+npm init
+npm init -y
+```
+
+#### .gitignore 쉽게 만들기
+
+<https://www.toptal.com/developers/gitignore/>
+
+### 2. 타입스크립트
+
+타입스크립트는 자바스크립트에 타입을 부여한 언어
+
+```sh
+npm i -D typescript
+```
+
+#### 실행(컴파일)
+
+```sh
+npx tsc --init
+```
+
+- tsconfig.json 파일로 설정
+
+### 3.lint
+
+린트는 소스코드를 분석하여 문법적인 오류나 스타일적인 오류, 적절하지 않은 구조 등에 표시를 달아주는 행위
+다른 사람과 협업을 할 때 코드의 형식을 맞추는데 도움을 준다.
+
+```sh
+npm i -D eslint
+```
+
+- .eslintrc.js 파일을 생성 후 설정
+- .eslintignore 파일 생성 후 설정
+
+### 4. 리액트 설치
+
+```sh
+npm i react react-dom
+npm i -D @types/react @types/react-dom
+```
+
+### 5. 테스팅 라이브러리
+
+```sh
+npm i -D jest @types/jest @swc/core @swc/jest jest-environment-jsdom
+npm i -D @testing-library/react @testing-library/jest-dom
+```
+
+- jest.config.js 파일 설정
+ - 테스트에서 SWC 사용
+
+```javascript
+module.exports = {
+ testEnvironment: 'jsdom',
+ setupFilesAfterEnv: [
+ '@testing-library/jest-dom/extend-expect',
+ './jest.setup',
+ ],
+ transform: {
+ '^.+\\.(t|j)sx?$': ['@swc/jest', {
+ jsc: {
+ parser: {
+ syntax: 'typescript',
+ jsx: true,
+ decorators: true,
+ },
+ transform: {
+ react: {
+ runtime: 'automatic',
+ },
+ },
+ },
+ }],
+ },
+ testPathIgnorePatterns: [
+ '<rootDir>/node_modules/',
+ '<rootDir>/dist/',
+ ],
+};
+```
+
+### 6. parcel
+
+```sh
+npm i -D parcel
+```
+
+### 7. package.json
+
+parcel로 웹 서버를 띄워주기 때문에 source 추가
+
+```json
+"source": "index.html",
+"scripts": {
+ "start": "parcel --port 8080",
+ "build": "parcel build",
+ "check": "tsc --noEmit",
+ "lint": "eslint --fix --ext .js,.jsx,.ts,.tsx .",
+ "test": "jest",
+ "coverage": "jest --coverage --coverage-reporters html",
+ "watch:test": "jest --watchAll"
+ },
+```
+
+### 8. 기본 파일 작성
+
+- `index.html`
+- `src/main.tsx`
+- `src/App.tsx`
+- `src/App.test.tsx`
+- `src/components/Greeting.test.tsx`
+- `src/components/Greeting.tsx`
+
+#### 기본 작성
+
+#### 1. index.html
+
+```html
+<!DOCTYPE html>
+<html lang="ko">
+ <head>
+ <meta charset="UTF-8" />
+ <meta name="viewport" content="width=device-width, initial-scale=1.0" />
+ <title>Document</title>
+ </head>
+ <body>
+ <div id="root"></div>
+ <script type="module" src="./src/main.tsx"></script>
+ </body>
+</html>
+```
+
+#### 2. main.tsx
+
+```javascript
+import ReactDOM from 'react-dom/client';
+function App() {
+ return <p>Hello, World!</p>;
+}
+const element = document.getElementById('root');
+if (element) {
+ const root = ReactDOM.createRoot(element);
+
+ root.render(<App />);
+}
+```
+
+설정 끝
