# 🌐 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 `enable_debug` flag that appends optional `console.log` statements for easier troubleshooting in staging or development.
