[React] 초기 세팅은 이렇게

CRA로 typescript 개발환경 설정하기

npx create-react-app "my-app" --template typescript

styled-components

npm i --save-dev @types/styled-components

Create a declarations file

//styled.d.ts
import "styled-components";

declare module "styled-components" {
  export interface DefaultTheme {
    bgColor: string;
    textColor: string;
    accentColor: string;
    cardColor: string;
  }
}

ThemeProvider

ThemeProvider를 통해 App 내에서 theme에 자유롭게 접근 가능.

//index.tsx
  <React.StrictMode>
      <ThemeProvider theme={Theme}>
        <App />
      </ThemeProvider>
  </React.StrictMode>

//theme.ts
import { DefaultTheme } from "styled-components";

export const Theme: DefaultTheme = {
  bgColor: "black",
  textColor: "whitesmoke",
};

createGlobalStyle

createGlobalStyle을 통해 globalStyle 적용

//App.tsx
import React from "react";
import styled, { createGlobalStyle } from "styled-components";

const GlobalStyle = createGlobalStyle`

function App() {
  return (

    </>
  );
}

export default App;

//index.tsx
  <React.StrictMode>
    <RecoilRoot>
      <ThemeProvider theme={Theme}>
        <App />
      </ThemeProvider>
    </RecoilRoot>
