Login with MetaMask

Live Demo 🚀

The working app can be seen on Firebase: https://login-with-metamask.firebaseapp.com.

The backend is hosted on Now by Zeit: https://login-with-metamask.now.sh/api/users

Getting Started

The app is made out of a backend which is a REST API written in Express, and a frontend which is a React single-page application. It's really a demo, so I tried to use as few libraries as possible.

To start the backend:

cd backend
yarn install
yarn dev # Will reload the node app on file changes

The backend should be running on localhost:8000.

To start the frontend:

cd frontend
yarn install
yarn start # Will refresh the page on file changes
