add_javascript_code

Simply Add JavaScript Code is a free PrestaShop module designed to help store owners and beginners safely inject custom JavaScript into their storefront without editing template (TPL) files. Manually modifying theme files to add scripts is error-prone — edits can be lost during theme updates, may expose the store's configuration to external observers, or cause a 500 server error if the syntax is incorrect. This module eliminates those risks by providing a dedicated, structured way to manage custom JavaScript snippets.

• Adds custom JavaScript to the storefront without touching template files
• Reduces the risk of losing custom code during theme updates
• Prevents potential 500 errors caused by improper manual script integration
• Keeps injected scripts from being easily visible to external parties

This module is particularly well-suited for PrestaShop beginners who need to integrate third-party scripts — such as analytics tools, chat widgets, or tracking pixels — without the technical confidence to safely edit theme files. Developers who want a clean, manageable approach to script injection will also find it a practical utility for their workflow.
