Must Have Ruby Gems and setups

Production Environment

For database/codebase backup

gem backup - Easy full stack backup operations on UNIX-like systems

For Log file backup

Log Rotate - Keep your log files in check as time goes on and make sure they don’t fill up your server’s disk space (log rotate)

For Exception tracking and logging

gem rollbar - Exception tracking and logging from Ruby to Rollbar

Rack middleware for blocking & throttling abusive requests

gem rack-attack - Rack::Attack is a rack middleware to protect your web app from bad clients. It allows safelisting, blocklisting, throttling, and trackingbased on arbitrary properties of the request.

Development Environment

For debugger

gem pry - An IRB alternative and runtime developer console

For N+1 queries

gem bullet - help to kill N+1 queries and unused eager loading

For soft delete

gem Paranoia - When your app is using Paranoia, calling destroy on an ActiveRecord object doesn't actually destroy the database record, but just hides it.

For security vulnerability

gem brakeman - Brakeman is an open source static analysis tool which checks Ruby on Rails applications for security vulnerabilities.

List of things to be cared before going live

• Tests passing?
• SSL Certificates
• Check it through webpagetest.org for problematic load times
• Set up any workers and autoscalers

Listed few and I’m planning to add more when I come across with useful gems.

Readers please comment with the gem list, which you feel like must have.
