A lightweight JSON-based database built entirely with Node.js and the Filesystem (fs) module — no external database required.
Each record is stored as a JSON line in text files, allowing fast appends, indexed lookups, and simple querying.
-
Store and retrieve JSON objects directly from
.dbfiles -
Supports CRUD operations (Create, Read, Update, Delete)
-
Uses fs.promises for modern asynchronous handling
-
Append-only logging for durability and simplicity
-
Query data using intuitive syntax like:
-
db.find({ name: "John" }) -
Lightweight and dependency-free — perfect for small projects or prototypes
- Node.js
- fs/promises
- path
- crypto (optional, for IDs or hashing)
Implement file-based product database with logging
- Added Database class to handle product storage in a JSON file.
- Implemented methods to add products, find products by ID, and retrieve all products.
- Integrated pino logger for structured logging of operations and errors.
- Ensured duplicate product IDs are not added and logged appropriate warnings.
- Handled file read/write operations with error logging for robustness.
