I am creating a plugin for Nodebb forum which works like this:
User(A) created his account - > he gets a referral code (his username)
Anyone(B) uses his referral code while registration + earns 150 currency -> User(A) gets 20 points for each such user.

I have already created the repository and following modules:

Registration screen has input for referral code.
If referral is entered is cross checked against all registered user names.
If founds a matching username, inside a new hash the new user and original users are mapped.
Else displays the message the wrong "referral code entered".
If no referral code was entered user is registered as normal and no mapping happens.

here is the link to the repository https://github.com/ethicalvats/nodebb-plugin-ds-refferal

Hello NodeBB developers and other enthusiasts. I am happy to announce that we at icfclub.in have recently launched a community forum which is proudly built upon NodeBB. I have started this unique thread to discuss regarding the same.

I am Vatsal Mishra, lead of technology team. We will appreciate everyone who will help us in building out this forum and getting it ready to be launched massively in India.

A little about us, icfclub.in main website is built upon Wordpress and we have around 5000 visitors count everyday where we showcase latest Ecommerce deals and coupons posted across various Ecommerce websites in India for e.g Flipkart and Snapdeal. We rank no. 3rd in our niche market which is "deal aggregator" across whole nation. We are planning to step into the next level of community building and engagement for that we need an exceptional quality forum which is fast and efficient and also has good support for mobile platforms. And we found all of these qualities in NodeBB forum software after evaluating lots of other possible alternatives, which is good news for all of us

We are speculating to bring about 2000 daily visits on our forum by this December and 100+ simultaneous online users.

We hope you guys will support our cause and will help us in many possible ways.

@meetdilip yeah we are quite excited

@meetdilip hey though it is hard to figure out the exact issue by the given symptoms but try running in dev mode by

./nodebb dev

and keep an eye on the log screen, it has the feature of restarting automatically after any error or failure. See the log for errors (in red) to figure out which plugin or script is causing the problem then you will be much closer to solving your problem.
