Stop Using Next.js Starters! Build a Modern Full-Stack App from Scratch (Bun & Express) | AI APPS #4

Video Description

Are you tired of bloated starter templates and complex frameworks like Next.js? In this lesson from Nemesis Courses, we are building a clean, modern, and lightweight full-stack application foundation from scratch. We ditch Node.js for Bun—the incredibly fast all-in-one JavaScript runtime—and set up a manual monorepo structure using Workspaces. You will learn how to configure TypeScript, manage environment variables securely, and build a type-safe Express backend without the hidden magic of big frameworks. In this video, you will learn: 🚀 Why Bun? Using it as a runtime, package manager, and bundler. 📂 Project Architecture: Setting up a clean Monorepo with Bun Workspaces. 🔒 Security: Managing API keys and Environment Variables properly with .env. 💻 Backend Setup: Building a TypeScript-ready Express server from zero. 🛠️ Custom Scripts: Creating watch-mode scripts for a better developer experience.
