Hands-on

~/develop/react/react_study$ yarn create react-app login --template typescript
cd login
yarn add @mui/material @emotion/react @emotion/styled

不要なファイルを削除する。

App.tsx

import CssBaseline from "@mui/material/CssBaseline";
import { ThemeProvider, createTheme } from "@mui/material/styles";
import Button from "@mui/material/Button";

function App() {
  const theme = createTheme({
    palette: {
      mode: "dark",
    },
  });

  return (
    <ThemeProvider theme={theme}>
      <CssBaseline />
      <Button variant="contained" color="primary">
        メインカラー(contained)
      </Button>
      <Button variant="outlined" color="secondary">
        セカンダリーカラー(outlined)
      </Button>
      <Button variant="text" color="success">
        サクセスカラー(text)
      </Button>
    </ThemeProvider>
  );
}

export default App;

これで完成。あとはyarn startで実行！！
