I recently faced the decision whether to rewrite<p>I took over a rails + angular 1 codebase from another developer who left the company. I would be working on the project for few months.<p>I rewrote the entire app with Meteor + React in few weeks. Best decision I ever made. Even though the app has same features, customers say the app is faster, has less bugs, and overall feels more solid. Security is also better because of the pub&#x2F;sub system. It also gave me a chance to fully understand the ins and outs of the database and how the app works.<p>I can also develop features much faster with Meteor + React than with Rails + Angular 1. So time spend re-writing is saved by enabling faster feature development.
