Follow the instruction to install prisma and create a new demo prisma database. You will also find how to setup your own database using docker if you are interested.
You need the demo database url from that tutorial. You can skip this part if you already have another prisma endpoint.
Create a .env file with the prisma api endpoint you got from step 1,
PRISMA_API=https://eu1.prisma.sh/abcdefg/hello-world/dev
API_PORT=4000
npm i -g dotenv-cli prisma yarn
Install all dependencies,
yarn install
Deploy the schema to endpoint,
dotenv -e .env prisma deploy
Start the app,
dotenv -e .env yarn start
Open browser and go to the playground at http://localhost:4000
