Challenges vs How i solved them

Challenges	How i solved them
Moving from MVC to MVCS architecture	Went through few websites and stackoverFlow and found out why i should revamp (optimised, reactor pattern, every module does one function rule, reuseablity)
Mongoose partial text based search	used a solution which utilises regex to solve this problem
Making task scheduler async	Went through a lot of packages and articles to solve this. thought of using setInterval but it would be optimsed for production level code.
Global error handling	I used to handle errors in try catch in every function, then learnt about Global error handling
Global Async handler	I used to handle async functions, then learnt about Global Async handler
