The project is a Rack middleware to automatically log a HTTP request to a custom object.

There might be no commits in months or years. Rack middlewares rarely change.

gem install rack-request-object-logger

gem 'rack-request-object-logger'

Tested with Matz Ruby 2.7, 3.0, 3.1, 3.2, 3.3, head, and ruffleruby, truffleruby-head.

Should work also with jRuby, just sqlite3 adapter supports only Rails 7 and tests require a more recent Rails.

While the code works flawlessly

Bug: I learned at EuRuKo 2018 that my implementation of timings is wrong and not very accurate.

generate a model for storage

$ bin/rails g model AnalyticsRequest uid:string data:jsonb status_code:integer application_server_request_start:datetime application_server_request_end:datetime

add automatic logging via initializer

# config/initializers/log_requests.rb

Rails.application.config.middleware.use(RackRequestObjectLogger, AnalyticsHttpRequest)

To run performance tests on your computer run rspec performance/. On my i5 laptop with ActiveRecord it processes and stores 500 logs per second, with dummy class 5000.

The logger sets the UUID of request to match the request ID set by Rails.

The middleware stores all HTTP headers, but strips all active_dispatch, warden and other stuff. That means HTTP basic auth credentials are stored and also data in query string.

I've seen applications sending sensitive data in GET and even POST requests in a query string. Don't do that. Use POST body. Or modify the middleware to filter out them.
