Natours Backend API

01 / The idea

Overview

A tour-booking REST API built while following a Node.js course, covering users, tours, and reviews with JWT authentication, role-based permissions, filtering, sorting, and pagination.

Natours is the backend API for a tour marketplace, organizing the core workflows around accounts, tour inventory, reviews, and protected operations. Its REST endpoints support complete resource management while reusable query utilities give catalogue consumers control over filtering, sorting, selected fields, and pagination. Authentication, permission checks, validation, sanitization, centralized errors, and secure password flows form the security boundary around the data.
