What happened

Remove Pronto and setup Danger for automated code review

Insight

• Remove completely pronto related things
• Add danger gem and its plugins
• Create a new workflow for danger checks:
  • I want danger to run as fast as possible, so I create a new workflow and just install node, ruby, bundler and run dependencies installers instead of using docker
  • Add caching to improve the checks
• Add team-nimblehq as bot:
  • Add team-nimblehq to repo with write access (use write instead of read as we need to set the status of the PR)
  • Create a new token for team-nimblehq with public_repo access
• Because of removing pronto-eslint_npm that includes scss_lint, we have to install scss_lint to use scss_lint
• List of danger plugins:

  gem 'danger-brakeman_scanner' # Security static analysis scanner in danger
  gem 'danger-eslint' # Lint JavaScript code
  gem 'danger-rails_best_practices' # Analyze code regarding best practices
  gem 'danger-reek' # Detect code smell
  gem 'danger-rubocop' # A Danger plugin for Rubocop
  gem 'danger-slim_lint' # Lint slim files
  gem 'danger-suggester' # Suggest code changes based on configured code

• Remove duplicated checks in codebase_spec
• Run workflow with pull_request event and [opened, reopened, synchronize] types
