Environment Best Practices

Development Stores

• Free for Partners
• Sandbox for testing
• No impact on production
• Can transfer to client

# Create development store
# Visit partners.shopify.com
# Stores > Add store > Development store

Theme Environments

• Development: shopify theme dev or --development flag
• Staging/Preview: --unpublished flag
• Production: Published theme

Version Control

# Initialize git
git init

# Add .gitignore
echo "config/settings_data.json" >> .gitignore
echo "node_modules/" >> .gitignore
echo ".DS_Store" >> .gitignore

# Commit theme
git add .
git commit -m "Initial theme commit"

Important: .gitignore should exclude:

• config/settings_data.json (store-specific)
• node_modules/ (dependencies)
• .DS_Store (macOS files)

Debugging Techniques

Liquid Debugging

{%- comment -%}
  Debug output using assign and display
{%- endcomment -%}

{%- assign debug = true -%}

{%- if debug -%}
  <pre>
    Product: {{ product | json }}
    Cart: {{ cart | json }}
  </pre>
{%- endif -%}

Console Logging

{% javascript %}
  console.log('Product data:', {{ product | json }});
  console.log('Settings:', {{ section.settings | json }});
{% endjavascript %}

Theme Check Output

# Verbose output
shopify theme check --verbose

# Output to file
shopify theme check > check-results.txt

Performance Optimization

Image Optimization

{%- # Use appropriate image sizes -%}
<img
  srcset="
    {{ image | image_url: width: 400 }} 400w,
    {{ image | image_url: width: 800 }} 800w,
    {{ image | image_url: width: 1200 }} 1200w
  "
  sizes="(min-width: 1024px) 33vw, (min-width: 768px) 50vw, 100vw"
  src="{{ image | image_url: width: 800 }}"
  loading="lazy"
>

Asset Loading

{%- # Defer non-critical JavaScript -%}
<script src="{{ 'theme.js' | asset_url }}" defer></script>

{%- # Preload critical assets -%}
<link rel="preload" href="{{ 'theme.css' | asset_url }}" as="style">

Minimize Liquid Logic

{%- # Good - assign complex logic to variable -%}
{%- liquid
  assign is_on_sale = false
  if product.compare_at_price > product.price
    assign is_on_sale = true
  endif
-%}

{%- if is_on_sale -%}
  <span>On Sale</span>
{%- endif -%}

{%- # Bad - inline complex logic -%}
{% if product.compare_at_price > product.price %}
  <span>On Sale</span>
{% endif %}

CI/CD Integration

GitHub Actions Example

name: Deploy Theme

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Install Shopify CLI
        run: npm install -g @shopify/cli @shopify/theme
      - name: Push theme
        run: shopify theme push --development
        env:
          SHOPIFY_CLI_THEME_TOKEN: ${{ secrets.SHOPIFY_CLI_THEME_TOKEN }}

Common Commands Reference

# Authentication
shopify auth login

shopify theme --help                  # Show help
shopify theme dev --help              # Show dev command help

Troubleshooting

Development Server Not Starting

# Check if port is in use
lsof -i :9292

# Use different port
shopify theme dev --port=9293

Authentication Issues

# Re-authenticate
shopify auth logout
shopify auth login

Theme Push Conflicts

# Force push (caution: overwrites remote)
shopify theme push --force

# Pull first, then push
shopify theme pull
shopify theme push

Hot Reload Not Working

• Ensure using Chrome browser
• Check file paths are correct
• Restart dev server
• Clear browser cache

Best Practices

1. Use development stores for testing
2. Push unpublished first before publishing
3. Run theme check before deploying
4. Use version control (Git)
5. Exclude settings_data.json from Git
6. Test on multiple devices before publishing
7. Keep CLI updated: npm update -g @shopify/cli
8. Use theme editor sync during development
9. Document custom features in README
10. Follow Shopify theme requirements for Theme Store

Use these tools and workflows to build, test, and deploy Shopify themes efficiently.
