5 Ways To Build A Sveltekit Contact Form
Quick Links :

Building a contact form is a crucial aspect of any website, as it provides a convenient way for visitors to get in touch with you. When it comes to SvelteKit, a popular framework for building web applications, creating a contact form can be a bit tricky. However, with the right guidance, you can build a functional and efficient contact form that meets your needs. In this article, we will explore five ways to build a SvelteKit contact form, each with its unique features and benefits.
What is SvelteKit?

Before we dive into building a contact form, let's take a brief look at what SvelteKit is. SvelteKit is a framework for building web applications using Svelte, a lightweight JavaScript compiler. It provides a set of tools and features that make it easy to build fast, scalable, and maintainable web applications. With SvelteKit, you can create server-rendered, statically generated, or single-page applications with ease.
Method 1: Using SvelteKit's Built-in Form Handling

One of the easiest ways to build a contact form in SvelteKit is to use its built-in form handling feature. This feature allows you to create forms that can be submitted to a server-side endpoint, where the data can be processed and stored. To use this feature, you need to create a form component in your SvelteKit app and configure it to submit data to a server-side endpoint.
Here's an example of how you can create a contact form using SvelteKit's built-in form handling:



  Name:
  
  Email:
  
  Message:
    <button type="submit">Send</button>
</form>
</code></pre>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">In this example, we create a form component that submits data to a server-side endpoint <code class="cw pn po pp pf b">/api/contact</code>. The <code class="cw pn po pp pf b">handleSubmit</code> function is called when the form is submitted, and it sends the form data to the server-side endpoint using the <code class="cw pn po pp pf b">fetch</code> API.</p>
<h2>Method 2: Using a Third-Party Library like Formik</h2>

</div>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Another way to build a contact form in SvelteKit is to use a third-party library like Formik. Formik is a popular library for building forms in React, but it can also be used in SvelteKit. Formik provides a set of features that make it easy to build complex forms, including validation, error handling, and submission handling.</p>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Here's an example of how you can create a contact form using Formik in SvelteKit:</p>
<pre class="oz pa pb pc pd pe pf bo ph ba bj"><code class="hljs"><script>
  import { Formik, Form, Field, ErrorMessage } from 'formik';

  const handleSubmit = async (values, { setSubmitting }) => {
    try {
      const response = await fetch('/api/contact', {
        method: 'POST',
        body: JSON.stringify(values),
        headers: { 'Content-Type': 'application/json' },
      });
      const data = await response.json();
      console.log(data);
    } catch (error) {
      console.error(error);
    } finally {
      setSubmitting(false);
    }
  };

  const validationSchema = {
    name: {
      required: 'Name is required',
    },
    email: {
      required: 'Email is required',
      email: 'Invalid email address',
    },
    message: {
      required: 'Message is required',
    },
  };
</script>

<Formik
  initialValues={{ name: '', email: '', message: '' }}
  validationSchema={validationSchema}
  onSubmit={handleSubmit}
>
  {({ isSubmitting }) => (
    <Form>
      <Field type="text" name="name" placeholder="Name" />
      <ErrorMessage name="name" component="div" />
      <Field type="email" name="email" placeholder="Email" />
      <ErrorMessage name="email" component="div" />
      <Field type="textarea" name="message" placeholder="Message" />
      <ErrorMessage name="message" component="div" />
      <button type="submit" disabled={isSubmitting}>
        Send
      </button>
    </Form>
  )}
</Formik>
</code></pre>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">In this example, we create a form component using Formik. We define the initial values, validation schema, and submission handler using Formik's APIs. The <code class="cw pn po pp pf b">handleSubmit</code> function is called when the form is submitted, and it sends the form data to the server-side endpoint using the <code class="cw pn po pp pf b">fetch</code> API.</p>
<h2>Method 3: Using a Serverless Function</h2>
<div style="text-align: center;margin: 40px 0px;">
  <img src="https://cdn.geupap.com/images/serverless-45321.jpg" alt="Serverless function">
</div>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Another way to build a contact form in SvelteKit is to use a serverless function. A serverless function is a cloud-based function that can be triggered by an HTTP request. In this approach, we create a serverless function that handles the form submission and sends the data to a server-side endpoint.</p>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Here's an example of how you can create a contact form using a serverless function in SvelteKit:</p>
<pre class="oz pa pb pc pd pe pf bo ph ba bj"><code class="hljs"><script>
  export async function handleFormSubmission(event) {
    const formData = new FormData(event.target);
    const response = await fetch('/api/contact', {
      method: 'POST',
      body: formData,
    });
    const data = await response.json();
    console.log(data);
  }
</script>

<form on:submit={handleFormSubmission}>
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" />
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" />
  <label for="message">Message:</label>
  <textarea id="message" name="message" />
  <button type="submit">Send</button>
</form>
</code></pre>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">In this example, we create a form component that submits data to a serverless function. The <code class="cw pn po pp pf b">handleFormSubmission</code> function is called when the form is submitted, and it sends the form data to a server-side endpoint using the <code class="cw pn po pp pf b">fetch</code> API.</p>
<h2>Method 4: Using a Third-Party Service like Formspree</h2>
<div style="text-align: center;margin: 40px 0px;">
  <img src="https://cdn.geupap.com/images/formspree-54321.jpg" alt="Formspree logo">
</div>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Another way to build a contact form in SvelteKit is to use a third-party service like Formspree. Formspree is a service that allows you to create forms that can be submitted to a server-side endpoint. In this approach, we create a form component that submits data to Formspree's API.</p>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Here's an example of how you can create a contact form using Formspree in SvelteKit:</p>
<pre class="oz pa pb pc pd pe pf bo ph ba bj"><code class="hljs"><script>
  export let name = '';
  export let email = '';
  export let message = '';

  async handleSubmit(event) {
    event.preventDefault();
    const formData = new FormData(event.target);
    const response = await fetch('https://formspree.io/f/mrnjorpn', {
      method: 'POST',
      body: formData,
    });
    const data = await response.json();
    console.log(data);
  }
</script>

<form on:submit={handleSubmit}>
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" bind:value={name} />
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" bind:value={email} />
  <label for="message">Message:</label>
  <textarea id="message" name="message" bind:value={message} />
  <button type="submit">Send</button>
</form>
</code></pre>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">In this example, we create a form component that submits data to Formspree's API. The <code class="cw pn po pp pf b">handleSubmit</code> function is called when the form is submitted, and it sends the form data to Formspree's API using the <code class="cw pn po pp pf b">fetch</code> API.</p>
<h2>Method 5: Using a Custom Solution</h2>
<div style="text-align: center;margin: 40px 0px;">
  <img src="https://cdn.geupap.com/images/custom-solution-21987.jpg" alt="Custom solution">
</div>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Finally, you can build a contact form in SvelteKit using a custom solution. This approach involves creating a custom form component that submits data to a server-side endpoint using a custom API.</p>
<p class="my mz gt na b nb nc nd ne nf ng nh ni nj nk nl nm nn no np nq nr ns nt nu nv gm bj">Here's an example of how you can create a contact form using a custom solution in SvelteKit:</p>
<pre class="oz pa pb pc pd pe pf bo ph ba bj"><code class="hljs"><script>
  export let name = '';
  export let email = '';
  export let message = '';

  async handleSubmit(event) {
    event.preventDefault();
    const formData = new FormData(event.target);
    const response = await fetch('/api/contact', {
      method: 'POST',
      body: formData,
    });
    const data = await response.json();
    console.log(data);
  }
</script>

<form on:submit={handleSubmit}>
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" bind:value={name} />
  <label for="email">Email:</label>
  <input type="email" id="email" name="email" bind:value={email} />
  <label for="message">Message:</label>
  <textarea id="message" name="message" bind:value={message} />
  <button type="submit">Send</button>
</form>
