This is my version of the Expense Tracker from Traversy Media's YouTube course, remade from scratch, and refactored to use Vercel serverless API routes, instead of Express.
The app uses React Context and Hooks, and I decided to use Material UI for styling. There are other minor tweaks, as well.
In order to develop locally, you'll need the Vercel CLI
yarn
Add a .env.local file that includes a MONGODB_URI value.
