Laravel Passport: A tutorial and example build

Laravel Passport is described as an effective tool for setting up an authentication system for APIs, utilizing an OAuth2 server to create and validate tokens for user applications. The tutorial outlines the process of building a secure API that interacts with a database to manage employee data, secured by Passport to ensure only authenticated requests access protected information. REST APIs are highlighted for their flexibility and scalability but are noted to be stateless, requiring client applications to store and provide necessary credentials for each request. The guide explains creating a Laravel application, setting up Passport for authentication, and developing a database model and migration for employee data. It further details the creation of controllers and routes to handle user registration, authentication, and employee data operations like listing, adding, updating, and deleting records, all secured by requiring valid access tokens. The tutorial concludes with testing the API using Postman to demonstrate functionality.
