What i am asking may be new to you guys but why requirements are just like this i want to make system very fast
What i have is Codeigniter Site which use Java Api to get products and all ecommerce flow is coded in Java but running in Codeigniter using Request / Response Calls
But that was slow Yes is was.:::::: Here they hire me !!!!!
Now The Manager Decided to do some thing else and that is covert PHP coding into Mean Stack and continue Java as there is a lot more in Java and the main developer had work on it for 3 years
I am new to Mean i have to first Learn them and do it
Please guide me what stack is best
Mean Or Mern
And we have to use Mysql instead of Mongo DB
SO things we have to keep is Mysql & Java Api ( it also use Mysql)
There is nothing new, If you read about SOA or micro-services based applications you will see similar patterns where a part of system is coded in different language and other part in different communicating over message queue or HTTP calls.
The only difference between MEAN & MERN is the only front-end framework used Angular OR React (Selecting one of them is really a hard choice, you will find a lot of debates over Angular VS React). My personal preference is Angular but, many may argue for react.
Learning Node & Express is pretty straight and you will start working with them within days.

Considering both MEAN and MERN are full stack javascript frameworks this doesn't seem like a valid question. Do you intend to use both Mongo and MySQL? thats probably a bad idea. Are you going to convert the server side Java into node / express Javascript? I doubt it.
Is your question really should I use React / Angular?
It also sounds like Codeigniter was just the front end part and it would call to the Java API. If that was slow building a new UI won't make it faster. The Java API probably needs to be updated to fix the real performance issues here. My guess would be lots of bad sql queries.
