MERN Stack Authentication And Deployment

Explore Munchak authentication and deployment in this short series, learn how authentication works, and observe the registration and login flow that redirects users to the home page.

Set up an express server, install mongodb, a dev dependency for development, and dotenv for environment vars, create login and home pages, configure a cluster with IP whitelisting, and authentication.

Define a user model with name, email, and hashed password using a mongoose schema, implement register and login endpoints, and issue JWT tokens to protect routes with middleware.

Run the server and front-end concurrently, implement register and login with Axios post requests, and manage the authentication token in local storage for protected routes.

Deploy a MERN app by configuring production, serving the client build with Express, installing client dependencies, and pushing to Heroku with mongo and secret variables.
