React and GraphQL: Build an E-commerce App with Hygraph

What is Snipcart?

Explore how to implement Snipcart to manage cart and payment functions within a React e-commerce app. Understand how to embed Snipcart using CDN, configure it with API keys, and customize the shopping experience without building cart logic from scratch.

We'll cover the following...

Shopify and Snipcart, two highly regarded companies, have played a crucial role in making it incredibly simple to add e-commerce functionalities to any website or online application. Shopify was established in 20062006 to assist with managing everything related to e-commerce. Snipcart was introduced in 20132013 with the purpose of offering a superior checkout and carting experience.

Defining Snipcart

Snipcart is an e-commerce solution that allows businesses of all sizes to integrate shopping cart functionality into existing websites or web applications. We can integrate this carting system into any website using simple HTML and JavaScript codes. Snipcart does the following:

  • Manage e-commerce operations.

  • Provides a fully customizable frontend shopping cart.

  • Gives us access to its webhooks and APIs.

  • Gives us access to an entire merchant back office.

This means we can use Snipcart to handle e-commerce when creating a web page with whatever stack we want. We don't have to deal with the logic of carting from scratch or installing a complex library; instead, we use a dedicated library.

Snipcart is fully customizable, allowing us to change both the style of the cart and how it behaves using CSS and the Snipcart API. Since Snipcart is entirely HTML-based, it is straightforward to integrate into our website. We need to include the CDN in a script tag that the web page can access and then add the CSS classes and some attributes to our markup in order to use Snipcart.

Snipcart also makes it simple to accept payments in our shopping cart, including international payments through popular platforms such as Stripe, PayPal, and others. In conclusion, Snipcart makes it simple for us to implement a carting system for our website without wasting time or money. This lets us concentrate on the core development of our website.

Sign up with Snipcart

To begin using Snipcart, go to the official website and sign up for a free account by entering your email address. You’ll receive a verification email requesting that you click on a link. This will take you to a page where you can complete your registration by entering and verifying your password. You can choose not to fill in the website field.

If this is successful, it will direct you to your dashboard, where you’ll be required to enter some information. This is how your dashboard will appear:

This dashboard has many essential sections that help us track our products, set up our application, and much more. It also has a “TEST” and “LIVE” mode control at the top, which allows us to test our application before going “LIVE.” Using and getting started with Snipcart entails going through all the steps outlined below.

All we need to do is go ahead to install or embed Snipcart within our application so we can make use of it. Creating an account gives us an API key for both the “TEST” and “LIVE” modes.

Setting up Snipcart in a React application

The second step is to install Snipcart. Snipcart installation does not require an NPM package or anything other than embedding the Snipcart CDN.

The Snipcart CDN can be embedded in a few ways, but to get it to work with React, we will embed the CDN by first adding the script tags to our public/index.html file and then adding the div, which contains some configurations, to the App.js file. The public/index.html file is the starting point of our application and holds the root element. This means we can place our script tags here within the body tag.

Connect our e-commerce application to Snipcart

In the code above, between lines 21 and 26, we add the script tag, which gives us access to Snipcart and its features. Then we add a hidden div tag within our application's body tag that will contain configurations such as the API key. We can obtain our API key from the “Account” section of our dashboard. To access the account, click on the user icon in the upper-right corner of our screen.

Once the user icon is clicked, the side panel on the right will appear, showing more information. We scroll down to the account section and click on "API KEYS."

Once we click on the “API KEYS” tab, all information about our API keys will appear. We have two types of keys: public and secret. The secret key is always meant to be private because we can use it to access all the data of our Snipcart account. This key gives access to our RESTful API. For now, we are only concerned with implementing the carting system within our e-commerce project, so we only need the public key.

Now that we have our key, let's configure Snipcart in our public/index.html file. This div is hidden, so it doesn't affect the display of our web page or alter anything.

Adding API key to React application

In the code above, the hidden div between lines 32 and 38 has three significant attributes, which are the data-api-key on line 35, data-config-modal-style on line 36, and currency on line 37. They are all aimed at helping us achieve a friendly carting system. The data-api-key holds our public key. We then set the data-config-modal-style to side so that it only shows up as a small modal rather than a full page.

Let’s suppose we want to make use of a full page cart. In that case we can do away with the data-config-modal-style attribute and its value. Next, we have currency, which we set as USD. We can change our value and ensure it reflects in our Snipcart settings.
