No more excuse about the backend not being ready.
Depending upon which datasource you're using (in our case mongodb)
From your terminal:
export DATABASE_URL="mongodb+srv://<USER>:<PASS>@cluster0.mxx5x.mongodb.net/<DATABASE_NAME>?retryWrites=true&w=majority"
And then
npm run dev
This starts your app in development mode, rebuilding assets on file changes.
