Shopify Theme Dev: Local Development

Using Shopify Theme Dev

Shopify theme dev (shopify theme dev) is the command for local theme development:

What shopify theme dev Does

• Starts local development server
• Connects to your Shopify store
• Enables hot reload (instant preview of changes)
• Opens store in browser automatically
• Syncs local files with store in real-time
• Provides local preview URL
• Allows offline development (with sync when online)

Development Workflow

1. 1

   Start Dev Server

   Run `shopify theme dev` in your theme directory. The CLI asks which store to use (select your development store). The server starts and your store opens in browser.

2. 2

   Edit Files Locally

   Edit theme files in your code editor (VS Code, etc.). Make changes to Liquid templates, CSS, or JavaScript. Save files automatically.

3. 3

   See Changes Instantly

   Changes sync automatically to your dev store. Browser refreshes automatically (hot reload). See updates immediately without manual upload. Much faster than theme editor.

4. 4

   Test and Iterate

   Test changes in browser, make adjustments, iterate quickly. Hot reload makes development very fast. Fix issues immediately.

5. 5

   Push When Ready

   When theme is complete, use `shopify theme push` to upload to store. Or push as draft first with `--unpublished` flag to review before publishing.

Liquid Templating Language

Understanding Liquid

Liquid is Shopify’s templating language used in all themes:

Liquid Basics

• Objects - Access data ({{ product.title }})
• Tags - Control flow ({% if %}, {% for %})
• Filters - Modify output ({{ price | money }})
• Variables - Store values
• Includes - Reuse snippets
• Sections - Modular components

Common Liquid Patterns

Accessing product data:

{{ product.title }}
{{ product.price | money }}
{{ product.description }}

Looping through collections:

{% for product in collection.products %}
  {{ product.title }}
{% endfor %}

Conditional logic:

{% if product.available %}
  Add to Cart
{% else %}
  Sold Out
{% endif %}
