Build a Full Inventory Mgt System Using SpringBoot & Angular

Initialize a spring boot backend project via start.spring.io with java, maven, and core dependencies like spring web, jpa, and mysql; add jwt and model mapper for auth and dto mapping.

Define and integrate custom exceptions and a global exception handler in a spring boot and angular inventory app, enabling clear 404, 400, 401, and 403 responses.

Configure spring security for the inventory app by implementing a custom user details service and a JWT-based authentication flow, enforcing access via roles and a dedicated auth filter.

Implement a complete user service for an inventory app, with register, login, update, delete, and get current user, plus retrieval of user transactions using jwt and password encoding.

Build and secure an auth and users controller in Spring Boot: implement register and login with validation, manage users with admin-only access, and expose endpoints for transactions and current user.

Test the category API with Postman by creating, retrieving, updating, and deleting categories using admin authorization and bearer tokens in a SpringBoot and Angular inventory system.

The lecture demonstrates supplier api testing with Postman, including adding, retrieving by id, updating, and deleting suppliers via a bearer token and json payloads.

Implement a transaction service that handles restock, sale, return to supplier, and transaction queries, including by month and year, with validation, status updates, and price calculations.

Register and protect login, register, category, supplier, product, and transaction routes with a canActivate guard, using admin-only controls and a default login redirect.
