React Portals are an incredibly powerful tool in React for rendering components outside their parent DOM hierarchy. By leveraging this feature in Next.js, you can achieve cleaner code and implement advanced UI patterns effectively. This blog dives into the depths of React Portals and their integration with Next.js, focusing on practical applications and best practices. Whether you are a beginner or an experienced developer, you will gain valuable insights into this versatile feature. Plus, we’ll highlight how Prateeksha Web Design can help small businesses create stunning, high-performance websites.
In React, components are typically rendered within their parent DOM hierarchy. However, there are situations where you need a component to appear outside of that structure, such as when creating modals, tooltips, or popovers. React Portals allow you to render elements into a different part of the DOM while maintaining their React context.
React Portals utilize the ReactDOM.createPortal(child, container)
method, which takes two arguments:
Here’s a simple example:
import ReactDOM from "react-dom";
function MyPortalComponent({ children }) {
return ReactDOM.createPortal(
children,
document.getElementById("portal-root")
);
}
In this case, the child component will render inside the #portal-root
element, regardless of its parent in the React tree.
Next.js, a popular React framework, is known for its focus on server-side rendering, static site generation, and excellent performance. Integrating React Portals into Next.js projects allows you to:
First, add a div
in your pages/_document.js
file to serve as the root for your portal components. The _document.js
file is where you can customize the HTML structure of your Next.js application.
// pages/_document.js
import { Html, Head, Main, NextScript } from "next/document";
export default function Document() {
return (
<Html>
<Head />
<body>
<Main />
<div id="portal-root"></div>
<NextScript />
</body>
</Html>
);
}
The #portal-root
div will act as the container for all your portal components.
Now, create a reusable Portal component to handle the portal logic. Here’s how you can do it:
import ReactDOM from "react-dom";
const Portal = ({ children }) => {
if (typeof window === "undefined") {
return null; // Return null during server-side rendering
}
const portalRoot = document.getElementById("portal-root");
return portalRoot ? ReactDOM.createPortal(children, portalRoot) : null;
};
export default Portal;
This component ensures compatibility with Next.js, where server-side rendering can cause issues with DOM-related operations.
Here’s how to use the Portal component in your application. Let’s create a modal as an example:
import React, { useState } from "react";
import Portal from "./Portal";
const Modal = ({ onClose }) => (
<div className="modal-backdrop">
<div className="modal-content">
<p>This is a modal!</p>
<button onClick={onClose}>Close</button>
</div>
</div>
);
const App = () => {
const [isOpen, setIsOpen] = useState(false);
return (
<div>
<button onClick={() => setIsOpen(true)}>Open Modal</button>
{isOpen && (
<Portal>
<Modal onClose={() => setIsOpen(false)} />
</Portal>
)}
</div>
);
};
export default App;
Portal
component example.Using portals for modals ensures they are rendered outside the main application DOM hierarchy, preventing issues with z-index and positioning.
Portals are ideal for displaying global notifications or toast messages at the top level of your application.
Use portals to create tooltips that appear in specific areas of your application without disrupting the existing DOM structure.
