Help where do I add custom javascript in shopify 2.0 theme?

I have been looking through the guides and tried google, but can not find a clear answer (for clarity the theme is tailor).

  • I don’t know where to place the custom code?
  • or where to call it from?
  • Most places tell me to do it somewhere in “editor code”, but am i correct in assuming custom code will disappear when updating a theme?

If somebody help me determine what is best practise, when I want to add place custom javascript code for my shopify store I would be very grateful.

Hi there,

I understand your concerns about adding custom JavaScript code to your Shopify store, especially with the “tailor” theme. It’s essential to follow best practices to ensure your custom code remains intact and doesn’t get lost during theme updates.

  1. Theme Customization: To safeguard your custom code, avoid editing the theme’s core files directly. Instead, consider creating a child theme or using Shopify’s built-in theme customization options.

  2. Shopify Script Editor: You can add custom JavaScript through the Shopify Script Editor:

    a. Go to your Shopify admin. b. Navigate to “Online Store” > “Themes.” c. Click the “Actions” dropdown and choose “Edit code.” d. In the “Assets” folder, create a new JavaScript file (e.g., custom.js) and add your code there.

  3. Sections and Templates: If you need JavaScript in specific sections or templates, you can insert your code directly into those files. Be sure to back up your code and proceed with caution.

  4. App Integrations: Some third-party apps may provide options for adding custom JavaScript. Check the app’s settings and documentation for guidance.

  5. Use Theme Hooks: Certain themes support hooks that allow you to insert custom JavaScript in specific areas without altering the theme files. Consult your theme’s documentation for details on available hooks.

  6. Backup and Documentation: Always document your custom code and maintain backups. This will help you easily reapply your changes if they are overwritten during theme updates.

  7. Testing and Monitoring: After implementing custom code, thoroughly test your store to ensure everything functions as expected. Regularly monitor your store’s performance, as updates may affect the compatibility of your custom code.

If you’re not comfortable with coding, it’s advisable to consult with a Shopify developer or expert. They can provide guidance and ensure that your customizations are correctly and securely implemented.

I hope this helps you on your journey to enhancing your Shopify store with custom JavaScript code. If you have any more questions or need further assistance, feel free to ask!
