kevinveenbirkenbachandClaude Opus 4.8 674d26de3a feat(lint/role-readme): derive Credits author from meta author SPOT
Role README Credits now name galaxy_info.author (plain bold or wrapped
in a Markdown link), matched byte-for-byte against the role's own
meta/main.yml, instead of a hard-coded maintainer name. Regenerate all
245 role README Credits blocks to the new 'Implemented by ...' format.

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, which is useful for global feature flags, analytics, or UI enhancements.

Overview

This role injects a custom JavaScript snippet into Nginx-served HTML responses via sub_filter.

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.
