Create App Layout With Navbar And Theme Toggle
=====================================================
Introduction
Creating a visually appealing and user-friendly app layout is crucial for a great user experience. In this article, we will guide you through the process of setting up a layout with a top navigation bar using styled-components. We will also include an app title and a toggle button for switching between light and dark themes.
Setting Up the Project
Before we begin, make sure you have the necessary dependencies installed in your project. You will need to install styled-components and react if you haven't already.
npm install styled-components react
Creating the Layout
Let's start by creating the layout component. We will use a functional component for this purpose.
// Layout.js
import React from 'react';
import Navbar from './Navbar';
const Layout = () => {
return (
<div>
<Navbar />
<main>
{/* Your app content will go here */}
</main>
</div>
);
};
export default Layout;
Creating the Navbar Component
Next, let's create the Navbar component. This component will contain the app title and the theme toggle button.
// Navbar.js
import React from 'react';
import { ThemeProvider, createTheme } from 'styled-components';
import ThemeToggle from './ThemeToggle';
const lightTheme = createTheme({
palette: {
mode: 'light',
},
});
const darkTheme = createTheme({
palette: {
mode: 'dark',
},
});
const Navbar = () => {
return (
<nav>
<h1>App Title</h1>
<ThemeToggle />
</nav>
);
};
export default Navbar;
Creating the ThemeToggle Component
The ThemeToggle component will be responsible for switching between the light and dark themes.
// ThemeToggle.js
import React from 'react';
import { ThemeProvider, createTheme } from 'styled-components';
const lightTheme = createTheme({
palette: {
mode: 'light',
},
});
const darkTheme = createTheme({
palette: {
mode: 'dark',
},
});
const ThemeToggle = () => {
const [theme, setTheme] = React.useState(lightTheme);
const toggleTheme = () => {
setTheme(theme === lightTheme ? darkTheme : lightTheme);
};
return (
<button onClick={toggleTheme}>
{theme.palette.mode === 'light' ? 'Dark Mode' : 'Light Mode'}
</button>
);
};
export default ThemeToggle;
Implementing the ThemeProvider
To use the themes in our app, we need to wrap our app with the ThemeProvider component.
// App.js
import React from 'react';
import Layout from './Layout';
import { ThemeProvider } from 'styled-components';
const App = () => {
return (
<ThemeProvider theme={lightTheme}>
<Layout />
</ThemeProvider>
);
};
export default App;
Adding Global Styles
To add global styles to our app, we can use the createGlobalStyle function from styled-components.
// GlobalStyles.js
import { createGlobal } from 'styled-components';
const GlobalStyles = createGlobalStyle`
body {
margin: 0;
padding: 0;
font-family: Arial, sans-serif;
}
`;
export default GlobalStyles;
Conclusion
In this article, we have created a layout with a top navigation bar using styled-components. We have also included an app title and a toggle button for switching between light and dark themes. We have implemented the ThemeProvider component to use the themes in our app and added global styles to our app.
