Node.js Interview Speedrun: Building Secure Authentication from scratch

Stop using Passport.js. Build Auth correctly. In this episode of The Commit Log, I speed-run a classic Senior Backend Interview question: Building a JWT Authentication System from scratch using Node.js, Express, and MongoDB. The Architecture: We skip the spaghetti code. I break down a proper MVC Structure: Controllers: Handling logic separate from routes. Middleware: Protecting routes with custom JWT verification. Security: Hashing passwords with bcrypt (never store plain text!). 👨‍💻 Source Code: [Link to your GitHub] Timeline: 0:00 - The Interview Challenge 1:15 - Database Setup (MongoDB) 2:30 - The Logic (Bcrypt & JWT) 4:00 - The Middleware (Protecting Routes) #Nodejs #ExpressJS #BackendDeveloper #CodingInterview #SystemDesign #JWT #WebDevelopment C.
