    Following is the step-by-step guide to Shopify theme app extensions.

    Step Number 1: Create A New Theme App Extension

    We’ll use Shopify CLI that we just installed.

    1. Run the following command in the terminal to create your new extension; make sure you are in the correct directory.
      npm run Shopify app generate extension
    2. Select Theme app extension as the type of extension.
    3. Enter an awesome name for your extension.

    After this, you’ll have an extension directory created in your project with a basic folder structure. All these folders are empty.

    Step Number 2: Populate Your Theme App Extension

    Before you are able to see your theme app extension, you also need to provide code. If you are just getting started, you may want to think about starting off by creating a simple app block. For instance, you might create a basic app block and place it in the blocks folder of your theme’s app extension:

    <span style=”color: {{ block.settings.color }}”>

    App blocks let you build powerful integrations with online store themes.


    {% render “app_snippet” %}

    {% schema %}


    “name”: “Hello World”,

    “target”: “section”,

    “stylesheet”: “app.css”,

    “javascript”: “app.js”,

    “settings”: [

    { “label”: “Color”, “id”: “color”, “type”: “color”, “default”: “#000000” }



    {% endschema %}

      1. Enabling development store preview on partners’ dashboard
      2. add your app block or app embed block to the host theme from the themes editor
    2. The preview link is mentioned at the bottom of the CLI output.
