Building a Newsletter Subscribe Component in Next.js with Lemon Squeezy

In this tutorial, you'll learn how to create a simple, elegant newsletter subscription component in a Next.js application using Lemon Squeezy's sign-up form POST endpoint.

Introduction

Newsletters are a fantastic way to keep your audience engaged, and creating a sleek subscription form in your Next.js app is easier than you think. Lemon Squeezy, known for its seamless e-commerce tools, offers a sign-up form POST request endpoint that we can leverage to create a newsletter subscription component.

Here’s a step-by-step guide to building your own subscription component.

Let’s get started! 👇

Understanding the Lemon Squeezy Sign-Up Endpoint

Lemon Squeezy provides a RESTful POST endpoint that allows you to programmatically subscribe users to your newsletter. Typically, it requires the following:

Email address: The subscriber’s email.
Additional fields: Depending on your setup, you might need to include tags or other metadata.

Creating the Subscription Form Component

Create a new file for your component, e.g., components/NewsletterSubscribe.js.

Next, you can configure your form input field to handle a submit function. Check out how we did it here in this code snippet.

const handleSubmit = async (e: any) => {
    e.preventDefault();

    setLoading(true);

    try {
       let response = await fetch(submit_url, {
            method: "POST",
            body: new FormData(e.target),
    });

       setLoading(false);

       if (response.ok) {
           setIsSuccess(true);
           // Redirect the subscriber
          // window.location.href = window.location.href; // page reload

          setTimeout(() => setIsSuccess(false), 3000);
      } else {
         // Something went wrong subscribing the user
         console.log("Sorry, we couldn't subscribe you.");
      }
   } catch (error) {
      setLoading(false);
      console.log("Sorry, there was an issue: " + error);
   }
};
