In this comprehensive guide, we’ll walk you through the step-by-step process of creating a Shopify app extension/embed that rendering custom content in existing liquid components. Buckle up, folks!

What is a Shopify App Extension/Embed?

A Shopify app extension(embed) is a custom piece of code that allows you to extend the functionality of your Shopify app by injecting custom content or functionality into existing liquid components. This could be anything from displaying a custom menu, adding a new payment gateway, or even creating a custom product page layout. The possibilities are endless!

Why Do I Need a Shopify App Extension/Embed?

There are several reasons why you might need a Shopify app extension/embed:

• Customization: You want to add custom functionality or content to your Shopify store that isn’t available through the theme editor.
• Flexibility: You need to integrate your app with existing liquid components, but don’t want to rewrite the entire codebase.
• Scalability: You want to keep your app’s functionality separate from the theme, making it easier to maintain and update.

Prerequisites

Before we dive into the tutorial, make sure you have the following:

• A basic understanding of HTML, CSS, and JavaScript.
• Familiarity with Shopify’s liquid templating language.
• A Shopify Partner account and a test store.
• A text editor or IDE of your choice (e.g., Visual Studio Code, Sublime Text).

Step 1: Create a New Shopify App

First things first, you need to create a new Shopify app. If you haven’t already, follow these steps:

1. Log in to your Shopify Partner account and click on “Apps” in the top navigation menu.
2. Click on “Create an app” and fill out the required information (e.g., app name, description, etc.).
3. Click “Create app” to create a new Shopify app.

Step 2: Create a New App Extension/Embed

Now that you have a new Shopify app, it’s time to create an app extension/embed. In your app’s dashboard, navigate to the “Extensions” tab and click on “Create an extension”. Fill out the required information, including:

Extension type	Select “Embed” as the extension type.
Embed name	Give your embed a unique name (e.g., “Custom Menu Embed”).
Embed description	Provide a brief description of your embed (e.g., “Renders a custom menu in the header”).

Click “Create extension” to create a new app extension/embed.

Step 3: Define the Embed’s Configuration

In the “Embed” tab, click on “Configuration” and define the following:

Namespace	Enter a unique namespace for your embed (e.g., “custom-menu-embed”).
Vendor	Enter your app’s vendor name (e.g., “my-app-vendor”).

Click “Save” to save your changes.

Step 4: Create the Embed’s Code

In the “Embed” tab, click on “Code” and create a new file called `embed.liquid`. This file will contain the code that will be injected into existing liquid components.

<!-- embed.liquid -->

<div>
  <p>This is a custom menu!</p>
  <ul>
    <li><a href="#">Menu item 1</a></li>
    <li><a href="#">Menu item 2</a></li>
  </ul>
</div>

This code will render a simple custom menu with two menu items. You can customize this code to suit your needs.

Step 5: Register the Embed

In the “Embed” tab, click on “Register” and register your embed with Shopify. This will make it available for installation in your test store.

Step 6: Install and Test the Embed

Log in to your test store and navigate to the “Apps” section. Click on “Get” next to your app’s name, and then click “Install” to install the app.

Once installed, navigate to the “Online Store” section and click on “Customize”. In the theme editor, click on the “Add section” button and select “App embeds”. Find your custom embed and click “Add” to add it to your theme.

Preview your theme to see your custom embed in action! You should see the custom menu rendered in the header.

Conclusion

And that’s it! You’ve successfully created and installed a Shopify app extension/embed that renders custom content in existing liquid components. Pat yourself on the back, because you’ve just unlocked a whole new level of customization and flexibility for your Shopify app.

• Using Shopify’s APIs to fetch data and render it in your embed.
