About This Episode:
Ever wondered how to persist data without setting up a full database? In this episode, we explore file-based storage in Node.js — a simple way to read, write, and manage data using the filesystem.
Perfect for small projects, prototypes, or when you just need to get things done quickly ⚙️💾
👉 You’ll learn how to:
- Read and write JSON files asynchronously using fs/promises
- Implement full CRUD (Create, Read, Update, Delete) operations
- Handle data safely and understand file-based storage limitations
- Prepare your app for a transition to a real database later
