Add a Contact Form to a React App with Netlify Forms

In this tutorial, you’ll learn how to add a contact form to a React application with Netlify Forms.

Adding a contact form to a React application might require writing server-side code to handle form submissions, but with Netlify Forms you can take a break from the logic, because it does all that behind-the-scenes work for you when your site is deployed on Netlify.

Prerequisites

To follow along with this tutorial, you should be familiar with React, Git and GitHub. You should also have a Netlify account and have Node installed on your machine. If you need any help getting set up, you can consult our guide on how to install Node using nvm.

What You’ll Learn

By the end of this tutorial, you’ll know how to do the following:

  • deploy a React app to Netlify
  • integrate Netlify Forms with a stateless form component (a form component that doesn’t use the state)
  • integrate Netlify Forms with a stateful form component (a form component that uses the state to handle its data)

The completed guide to this tutorial is available on GitHub.

Introduction to Netlify Forms

Netlify Forms is a feature of Netlify for managing and handling form submissions without having to write any server-side code. By adding a simple attribute to your HTML form tag, you can get up and running with Netlify Forms. Forms can also be submitted asynchronously with JavaScript, making it a great companion to sites powered by Vue, React, and other modern frameworks.

Netlify Forms Pricing

Netlify Forms is free to get started with, but there’s a limit of 100 form submissions per website per month on the free plan, and also some features like background functions and role-based access control are excluded while using the free tier.

To exceed the form submission limit or make the excluded features available, you’ll have to upgrade to a different plan. You can do that on the Netlify pricing page.

Creating a Form for Netlify Forms

Netlify Forms can be integrated with both a stateless form (a form that doesn’t use the state to handle its data) and stateful one (a form that uses the state to handle its data). In this tutorial, we’ll firstly create a stateless form to demonstrate how we can integrate Netlify Forms with it. But later on, we’ll refactor the stateless form into a stateful one, in which we’ll also integrate with Neltify Forms.

Let’s start by creating and setting up a new React app.

Create and set up React

Type the following command in your terminal to create a new React app:

$ npx create-react-app netlify_forms_app

Here our app’s name is netlify_forms_app, but you can give it any name you wish as long as it’s not a restricted npm name. After the installation is complete, change into the newly created directory, then start the app with the npm start command in your terminal.

Let’s clean up (optional) our app a little bit. In the src directory of the app, delete the following files:

  • App.test.js
  • logo.svg
  • setupTests.js

We deleted these files because they aren’t relevant to us in our build. We can also delete the reportWebVitals file. Doing that requires that we also remove the import statement and the function call of reportWebVitals from the index.js file for our React app to compile successfully. Again, this is all optional, so you can just skip this if you prefer.

Now, clean up the App.js file so that it looks like this:

// src/App.js
import './App.css';

function App() {
  return (

  );
}

export default App;

Creating a contact form component

In the src directory of our React app, create a Form.js file and add the following lines of code to it:

// src/Form.js
import './form.css'

export default function Form() {
  return (
    <form 
      method='POST' 
      name='contactform' 
      className='contactForm'>

      <input 
        type='text' 
        name='name' 
        placeholder='Enter your name' />

      <input 
        type='email' 
        name='email' 
        placeholder='Enter your email' />

      <textarea 
        name='message' 
        placeholder='Messaage'></textarea>

      <button type='submit'>Submit</button>

    </form>
  )
}

Here, we have a stateless React form. Now, go to the App.js file in the src directory and render the form. The App.js file should look like this:

import './App.css';
import Form from './Form'

function App() {
  return (
    <Form />
  );
}
export default App;

Styling the form component with plain CSS

In the src directory, create a form.css file and add the following style:

// src/form.css
.contactForm{
  padding: 10px;
  width: 90%;
  max-width: 400px;
  margin: 30px auto;
  border-radius: 10px;
  display: flex;
  flex-direction: column;
  gap: 20px;
}
.contactForm input, button, textarea{
  height: 50px;
  padding-left: 5px;
  font-size: 18px;
}
.contactForm textarea{
  height: 100px;
}

There’s no need to write any fancy CSS, but you can add some tweaks if you wish. With the styles we’ve added, our HTML form now looks like the image below.

A simple contact form made with React

To see the result, you’ll need to change into the netlify_forms_app folder and start the server:

cd netlify_forms_app
npm start

A browser will open up and you can view the result at http://localhost:3000.

Form Handling with a Stateless React Contact Form

A perfect example of a stateless React form is the one we created earlier. In this form, our input values aren’t controlled by the state. In this section, we’ll learn how to add a contact form to a stateless React app with Netlify Forms.

Adding a static HTML version of the form

The first step to enabling our form to work with Netlify Forms is to add a static HTML version of our form to the index.html file in the public directory of our React app. Why do we need to add this form? Adding this HTML form will help Netlify detect our JSX form, since the post-process bots can only parse HTML.

For this example, we’ll add this HTML form right after the opening the <body> tag in our index.html file:

<!-- public/index.html -->
<form name='contactForm' netlify hidden>
  <input type='text' name='name' />
  <input type='email' name='email' />
  <textarea name='message'></textarea>
</form>

There are two attributes to note in this form: name and netlify. The name attribute will enable Netlify to connect with our JSX form, while the netlify attribute will enable Nelify’s bot to be able to parse our form. We also used the hidden attribute to hide the form from our users. There’s no need to add labels or a submit button to this form, since it’s hidden from our site.

Add a hidden input element to the JSX form

In the Form.js file in the src directory, add a hidden input element with the name attribute set to form-name and the value attribute equal to the name of the HTML version of our form. These attributes are required to make our form work with Netlify Forms:

// src/Form.js
<input 
  type='hidden' 
  name='form-name'
  value='contactForm' />

The final version of our form now looks like this:

// src/Form.js
<form 
  method='POST' 
  name='contactform' 
  className='contactForm'>

  <input 
    type='hidden'
    name='form-name'
    value='contactForm' />

  <input 
    type='text' 
    name='name' 
    placeholder='Enter your name' />

  <input 
    type='email' 
    name='email' 
    placeholder='Enter your email' />

  <textarea 
    name='message' 
    placeholder='Messaage'></textarea>

  <button type='submit'>Submit</button>
</form>

There’s one more step required for this form to start working: deploying our React app to Netlify. We’ll cover this in the next section.

Deploying to Netlify

We can deploy our site to Netlify using a version control system like GitHub, or we can use the drag-and-drop method, which requires us to transfer the build file created from running the npm run build command to Netlify drag and drop page. Both methods of deployment will be covered in the following sections, but for this tutorial, we’re going to use GitHub for deployment.

Deploy with GitHub

Deploying our React app from GitHub will set us up for continuous deployment, meaning changes made to our repository will automatically trigger re-deployment of our site, which is an advantage over using the drag-and-drop method.

To be able to deploy from GitHub, we have to first make our React app available on it. Go over to GitHub and create a new repository.

Create a new repository page on GitHub

For this tutorial, we’ll name the repository “NelifyForms”. Now at the bottom of the page, click the Create Repository button and we’ll be redirected to the newly created repository page.

Created new repository

Right now, this repository is empty. That’s because we haven’t pushed our React app to it. To do that, enter the following commands in the terminal:

$ git add *
$ git commit -m 'netlify forms with stateless form'
$ git remote add origin <Your_repoistory's_url>
$ git push -u origin master

These commands will create a new commit, connect us to our GitHub repository, and finally push our React app over to it.

Make sure to replace with the URL of the newly created GitHub repository. Here’s an image that shows where to find the URL of the newly created repository.

Repositories URL

After running the above git commands, refresh the browser. You’ll find that our React app has been pushed to GitHub.

NetlifyForms repository

Now that our React app is available on GitHub, it’s time that we deployed it on Netlify. Log in to your Netlify account, go over to the dashboard, and click on the New site from Git button. We’ll be taken to the Create a new site page.

Create a new site page

Click on the GitHub button under the Continuous Deployment section. We’re then redirected to an authorization page where Netlify will ask for access to GitHub. After giving Netlify access, we’ll see a page like the one shown below.

Create a new site page

Right now, the NetlifyForms repository we created earlier is not displaying among the list of repositories, because we haven’t configured Netlify to access it yet.

To do that, click on the Configure the Netlify app on GitHub link at the bottom of the page. We’ll see a page like the one shown below.

Configuration page for Netlify on GitHub

Scroll to the bottom of the page under the Repositories access section and click on the Select repositories button. We’ll see a list of our GitHub repositories.

Configuration page for Netlify on GitHub

Select the NelifyForms repository and then click on save to give Netlify access to this repository. After saving it, we’ll be redirected to the Create a new site page on Netlify.

Create a new site page on Nelify

Our NetlifyForms repository is now displayed in the list. Click on it and we’ll see a page like this.

Site build and deployment page

On this page, we can set the build and deployment options for our site, like changing the Git branch to deploy from, or the command to be used to deploy our site. But there will be no need for that, because everything looks good by default.

Finally, to deploy our site to Netlify, scroll to the bottom of the page and click on the Deploy site button. The deployment might take a while, but once it’s done we’ll see a link to our site at the top right corner of the site dashboard page.

Sites URL

With this, our React app has been successfully deployed to Netlify from GitHub. When we click on the link, we’ll see the React form we built.
