How to Build a Referral Program with Node.js

Alex Cloudstar · DEV Community Free Intermediate

This is a hands-on walkthrough, not theory: it shows the actual pieces you need to ship the minimal version, a user schema, UUID-based referral code generation, and a registration endpoint that records who referred whom and credits the reward. It stays deliberately small (no configurable rewards, no heavy auth) which is exactly the right altitude when you are a solo dev trying to get a working referral loop live rather than a perfect one.

• A unique referral code can just be a UUID stored on the user record, you do not need a separate service or fancy encoding to start
• Attribution is one extra field: capture the referrer's code at signup and write the reward when the new account is created
• The sample is a proof-of-concept on purpose, so treat validation, error handling, and abuse prevention as the next pass once the loop actually works
