[React] Dark모드, Light모드 적용하기

index.tsx 에 있던 

<ThemeProvider theme={theme}>
</ThemeProvider>

이것을 app.tsx로 옮긴다.

 

theme를 darkTheme와 lightTheme로 나눠서 만들어준다.

 

//theme.ts


import { DefaultTheme } from "styled-components";

export const darkTheme:DefaultTheme = {
    bgColor: "#1e272e",
    textColor: "black",
    accentColor: "#f53b57",
}

export const lightTheme:DefaultTheme = {
    bgColor: "whitesmoke",
    textColor: "black",
    accentColor: "#f53b57",
}

 

버튼을 만들어서 적용한다.

//app.tsx

import styled, { createGlobalStyle } from "styled-components";
import { ThemeProvider } from 'styled-components';
import { darkTheme, lightTheme } from './theme';
import Router from './Router';
import { ReactQueryDevtools } from "react-query/devtools";


const GlobalStyle = createGlobalStyle`
