README

• Ruby version: 3.4.1

• Rails version: 8.0.1

• Only for running ESLint and stylelint

  • Node JS (used only for running ESLint and stylelint) version: 22.14.0
  • Yarn 4.7.0

• System dependencies

• Configuration

💡 Note: Multi environment credentials

To edit the credentials file, run EDITOR="nano" rails credentials:edit. This command will create the credentials file the config/master.key if there is no such file, and, also, the config/credentials.yml.encif it does not exist.

The master.key should be provisioned to the Rails app as the RAILS_MASTER_KEY environment variable by the hosting platform (Heroku).

Other credentials, including the secret_key_base, are typically stored in the encrypted files per environment in the config/credentials folder. These encrypted files could be edited, running in the terminal the following command:

$ EDITOR="nano" rails credentials:edit --environment=development

• Database creation

• Database initialization

• How to run the test suite

• Services (job queues, cache servers, search engines, etc.)

• Deployment instructions: git push heroku main or git push heroku branchname:main

TODO: remove public read access

AWS bucket policy is public read until [the issue in Camaleon CMS will get solved](https://github. com/owen2345/camaleon-cms/issues/955)

Current bucket policy:

Testing and profiling

The derailed_benchmarks gem is running performance test in production environment, so the production DB in the config/database.yml is pointing to the development DB.

The following specs could be run:

Static memory reports:

bundle exec derailed bundle:mem # Memory used at Require time

bundle exec derailed bundle:mem development # Memory used at Require time in `development` environment

bundle exec derailed bundle:objects # Objects created at Require time

bundle exec derailed bundle:objects development # Objects created at Require time in `development` environment

Dynamic profiling

$ bundle exec derailed exec --help
  $ derailed exec perf:allocated_objects  # outputs allocated object diff after app is called TEST_COUNT times
  $ derailed exec perf:app  # runs the performance test against two most recent commits of the current app
  $ derailed exec perf:gc  # outputs GC::Profiler.report data while app is called TEST_COUNT times
  $ derailed exec perf:heap  # heap analyzer
  $ derailed exec perf:ips  # iterations per second
  $ derailed exec perf:library  # runs the same test against two different branches for statistical comparison
  $ derailed exec perf:mem  # show memory usage caused by invoking require per gem
  $ derailed exec perf:mem_over_time  # outputs memory usage over time
  $ derailed exec perf:objects  # profiles ruby allocation
  $ derailed exec perf:stackprof  # stackprof
  $ derailed exec perf:test  # hits the url TEST_COUNT times
  $ derailed exec perf:heap_diff  # three heaps generation for comparison

ESLint

Run the following command:

yarn eslint

Stylelint

Run the following command:

yarn stylelint "**/*.{css,js,scss}"
