Are you tired of struggling with routing in NextJs? Do you want to create seamless form submissions that match your application’s routing perfectly? Look no further! In this comprehensive guide, we’ll take you through the process of using NextJs router to match forms, making your application more efficient and user-friendly.
Understanding NextJs Router
Before we dive into the nitty-gritty of matching forms with NextJs router, let’s quickly review what NextJs router is and how it works.
NextJs router is a built-in router that allows you to navigate between pages in your NextJs application. It provides a way to define routes, handle client-side routing, and generate static sites. With NextJs router, you can create routes using the `pages` directory, where each page is a separate route.
How NextJs Router Works
Here’s a high-level overview of how NextJs router works:
pagesdirectory: This is where you define your routes. Each file in this directory is a separate route.getStaticProps: This method is used to pre-render pages at build time. It returns an object with props that will be passed to the page component.getServerSideProps: This method is used to pre-render pages on the server-side. It returns an object with props that will be passed to the page component.useRouter: This hook provides access to the router object, which allows you to navigate between pages programmatically.
Setting Up NextJs Router for Form Submissions
Now that we’ve covered the basics of NextJs router, let’s set up our router to handle form submissions.
Create a Form Component
Create a new file called `Form.js` in your `components` directory:
<form> <label>Name:</label> <input type="text" name="name" /> <br> <label>Email:</label> <input type="email" name="email" /> <br> <button type="submit">Submit</button> </form>
Define the Route
Create a new file called `submit.js` in your `pages` directory:
import Head from 'next/head';
const SubmitPage = () => {
return (
<div>
<Head>
<title>Form Submission</title>
</Head>
<h1>Form Submission</h1>
<Form />
</div>
);
};
export default SubmitPage;
Configure NextJs Router
In your `next.config.js` file, add the following configuration:
module.exports = {
//... other configurations ...
async routes() {
return [
{
path: '/submit',
page: '/submit',
},
];
},
};
Matching Forms with NextJs Router
Now that we have our form and route set up, it’s time to match the form submission with the NextJs router.
Using the `useRouter` Hook
In your `Form.js` file, import the `useRouter` hook and use it to navigate to the `/submit` route when the form is submitted:
import { useRouter } from 'next/router';
const Form = () => {
const router = useRouter();
const handleSubmit = (event) => {
event.preventDefault();
router.push('/submit');
};
return (
<form onSubmit={handleSubmit}>
<label>Name:</label>
<input type="text" name="name" />
<br>
<label>Email:</label>
<input type="email" name="email" />
<br>
<button type="submit">Submit</button>
</form>
);
};
Using the `Link` Component
Alternatively, you can use the `Link` component from `next/link` to create a link to the `/submit` route:
import Link from 'next/link';
const Form = () => {
return (
<form>
<label>Name:</label>
<input type="text" name="name" />
<br>
<label>Email:</label>
<input type="email" name="email" />
<br>
<Link href="/submit">
<button type="submit">Submit</button>
</Link>
</form>
);
};
Handling Form Submissions with NextJs Router
Now that we’ve matched the form submission with the NextJs router, let’s handle the form submission on the `/submit` route.
Using `getServerSideProps`
In your `submit.js` file, use the `getServerSideProps` method to handle the form submission:
import { useState } from 'react';
const SubmitPage = () => {
const [formData, setFormData] = useState({});
return (
<div>
<h1>Form Submission</h1>
<p>Form data: {JSON.stringify(formData)}</p>
</div>
);
};
export const getServerSideProps = async (context) => {
const { req, res } = context;
const formData = req.body;
// Process form data
setFormData(formData);
return {
props: {},
};
};
Using API Routes
import { NextApiRequest, NextApiResponse } from 'next';
const handleSubmit = async (req: NextApiRequest, res: NextApiResponse) => {
const formData = req.body;
// Process form data
console.log(formData);
return res.status(201).json({ message: 'Form submitted successfully' });
};
