MERN Stack Authentication App

A secure, production-ready authentication boilerplate built with the MERN stack. This project serves as a robust starting point for full-stack applications requiring secure user management.

The app is essentially an Express server that exposes a series of RESTful API endpoints for basic user authetication using JWT tokens. Users can sign up for an account, login, logout, and reset their password. The data layer is handled by MongoDB and the popular Mongoose ODM. Password encryption is handled by bcrypt. Nodemailer is used to send password reset emails. Docker is used to set up a protable environment for development and production.

A simple React test client is configured to demonstrate the authentication flow as I imagined it working in a real-world application. Mailslurper is used in the test app as a local SMTP testing environment for password reset emails to avoid having to configuring a full blown email server for development.

Key Features
