RailsCdnOptimizer analyzes your Rails app's asset pipeline, detects large files, and suggests CDN caching rules to improve performance.

• Analyze app/assets, lib/assets, and vendor/assets
• Detect large files that may slow down page load
• Suggest caching headers for CDN optimization
• Generate JSON report for integration with monitoring tools
• Easy integration with Rake tasks

Add this line to your Gemfile:

gem 'rails-cdn-optimizer'

Rake Task

Generate a CDN analysis report:

bundle exec rake cdn:analyze

RailsCdnOptimizer.configure do |config|
  config.cdn_host = "https://cdn.yourdomain.com"
end


ASSET_PATH=spec/tmp_assets bundle exec rake cdn:analyze


[
  {
    "path": "application.js",
    "size_kb": 512,
    "suggestion": "Consider optimizing",
    "cdn_header": "Cache-Control: max-age=31536000, immutable"
  },
  {
    "path": "style.css",
    "size_kb": 120,
    "suggestion": "OK",
    "cdn_header": "Cache-Control: max-age=31536000, immutable"
  }
]
