🌐 Global JavaScript Injector for Nginx

Description

This Ansible role injects a custom JavaScript snippet into all HTML responses served by Nginx. It leverages Nginx’s sub_filter to seamlessly insert your application-specific script just before the closing </head> tag, ensuring that your code runs on every page load—perfect for global feature flags, analytics, or UI enhancements.

Features

  • One-line Script Injection
    Collapses your JavaScript into a single line and injects it via sub_filter for minimal footprint and maximal compatibility.

  • Easy CSP Integration
    Automatically computes and appends a CSP hash entry for your script, so you can lock down Content Security Policy without lifting a finger.

  • Conditional Activation
    Activates only when you enable the javascript feature for a given application, keeping your server blocks clean and performant.

  • Debug Mode
    Supports an MODE_DEBUG flag that appends optional console.log statements for easier troubleshooting in staging or development.
