How Can I Set a URL as a Prop Without Getting Undefined in Next.js?
If you are working with Next.js and trying to set a URL as a prop, you may have encountered the issue of getting an undefined value. This can be frustrating, but fortunately, there are a few solutions to this problem. In this blog post, we will explore these solutions and provide code snippets for each one.
Solution 1: Using Next.js Router
One way to set a URL as a prop without getting undefined is by using the Next.js Router. The Router object allows you to access the current URL and pass it as a prop to your components.
import { useRouter } from 'next/router';
const MyComponent = () => {
const router = useRouter();
const currentUrl = router.asPath;
return (
Current URL: {currentUrl}
);
};
Solution 2: Using getInitialProps
Another solution is to use the getInitialProps function provided by Next.js. This function allows you to fetch data and pass it as props to your components, including the URL.
import React from 'react';
import fetch from 'isomorphic-unfetch';
const MyComponent = ({ currentUrl }) => (
Current URL: {currentUrl}
);
MyComponent.getInitialProps = async ({ req }) => {
const currentUrl = req ? req.url : window.location.href;
return { currentUrl };
};
Solution 3: Using useRouter Hook
If you are using Next.js version 9.5 or above, you can also use the useRouter hook to access the current URL.
import { useRouter } from 'next/router';
const MyComponent = () => {
const router = useRouter();
const currentUrl = router.asPath;
return (
Current URL: {currentUrl}
);
};
These are three different solutions to set a URL as a prop without getting undefined in Next.js. Choose the one that best suits your project and enjoy passing URLs as props effortlessly!
