Here are the four Gems that I’ve built during my time as Rails developer.
HTML Render – Render HTML inside a JSON Response in Rails
Nonschema Migrations – Separate schema-only migrations from nonschema (data) migrations in your Rails app.
Universal Track Manager – A plug-and-play Rails engine for tracking your visitors’ IP address, the ad campaign where they came from, or the browser they are using.
Common Core JS — Scaffolding generation and rapid application prototyping tool for Rails.
