Change Dark theme React

I read a lots article of writing a toggle to change the theme. For a beginner, this is entire too difficult to understand multiple files and code.

I'm going to show you guys a simple way to change the by using useState and styled-components 😛 😝

Here is my step:

Step 1 :

Install styled-components, we need this library.

npm install --save styled-components

Step 2:
Import these things, you will use useState later 😏

import { ThemeProvider } from "styled-components";
import { createGlobalStyle } from "styled-components";
import { useState } from "react";

Step 3:
Initialize the Dark and Light
Simply define our lovely variable 😛:

  const [theme, setTheme] = useState("light");

  const light = {
    body: "#E2E2E2" // you can change to any color you like
  };

  const dark = {
    body: "#363537" // you can change to any color you like
  };

  const GlobalStyle = createGlobalStyle`
  body{
    background: ${({ theme }) => theme.body};
  }
  `;

Step 4:
Return

import "./styles.css";
import { ThemeProvider } from "styled-components";
import { createGlobalStyle } from "styled-components";
import { useState } from "react";

export default function App() {
  const [theme, setTheme] = useState("light");

  const light = {
    body: "#E2E2E2"
  };
  const dark = {
    body: "#363537"
  };

  const GlobalStyle = createGlobalStyle`
  body{
    background: ${({ theme }) => theme.body};
  }
  `;

  return (
    <ThemeProvider theme={theme === "light" ? dark : light}>
      <GlobalStyle />
      <button
        onClick={() => {
          if (theme === "light") {
            setTheme("dark");
          } else {
            setTheme("light");

          }
        }}
      >
        change
      </button>
    </ThemeProvider>
  );
}

Here is a demo:

Hope these help you, Thanks for reading, Have fun! 🥰
