A full-stack, catalog-style CRUD application for managing and browsing products by category — built with Node.js, Express, MongoDB, Mongoose, and EJS.

• View all products in a table
• Filter products by category
• Add new products (with name, price, image, category, and description)
• Edit existing products
• Delete products
• Product details page now shows creation and last updated timestamps
• Clean, responsive UI with EJS and Bootstrap 5
• Robust error handling for validation errors, invalid ObjectIds, and missing resources — all errors are shown on a custom, responsive error page for a better user experience.

• GET /products – View all products
• GET /products/new – Open the form to add a new product
• GET /products/:id – View product details
• GET /products/:id/edit – Edit an existing product
• DELETE /products/:id – Delete a product (via form submission)
• ERROR /products/:invalidID – Displays a user-friendly error message for invalid requests or missing resources

Attempting to access a valid but non-existent product ID:

• Node.js
• Express
• MongoDB
• Mongoose
• EJS
• Bootstrap

npm install

MongoDB must be running for the app to work. If it’s not running automatically, start it manually:

mongod

To populate your database with sample products, run:

node seeds.js

This will clear any existing products and insert fresh seed data.

nodemon index.js

If you don’t have nodemon installed globally, you can install it with npm install -g nodemon, or simply run node index.js instead. To stop the server, press Ctrl + C in the terminal.

The app will be available at http://localhost:3000/products.

• index.js – Main Express app; sets up middleware, connects to MongoDB, mounts routers, and starts the server.
• routes/products.js – Router module containing all product-related routes.
• models/product.js – Mongoose schema and model definition.
• seeds.js – Script to seed the database with sample products.
• views/products/index.ejs – Displays the list of products.
• views/products/details.ejs – Shows individual product details.
• views/products/edit.ejs – Form to edit an existing product.
• views/products/new.ejs – Form to add a product.
• wrapAsync.js – Utility to catch async errors cleanly.
• appError.js – Custom error class for structured error responses.
• validateObjId.js – Middleware to handle invalid ObjectId formats.
• views/error.ejs – Styled error page for displaying validation errors, invalid ObjectIds, etc.
