unipisa/dm-coffee

coffee counter

This is a Next.js project bootstrapped with create-next-app.

Configuration

Configuration is done through environment variables. You can create a .env file in the root directory. See the file app/config.ts for the list of available environment variables.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Inter, a custom Google Font.

emulating the card reader

per simulare il passaggio della tessera 1234 bisogna mettere un token segreto nella variabile d'ambiente CARD_SECRET_TOKENS (si possono inserire più tokens separati da una virgola) e poi si può dare il comando

CODE=codice_tessera
CARD_SECRET_TOKEN=codice_segreto
curl 'http://localhost:3000/graphql' -H "Authorization: ${SECRET_TOKENS}" -H 'content-type: application/json' --data-raw '{"operationName":"Card","variables":{"code":"'"${CODE}"'"},"query":"mutation Card($code: String!) {\n  card(code: $code)\n}"}'

inserting a transaction with an API call

Per automatizzare l'inserimento delle transazioni da altre fonti (ad esempio dai pagamenti di paypal) si può fare una chiamataa alle API utilizzando un token invece che username e password di amministratore. Il token (un codice segreto) va inserito nella variabile d'ambiente ADMIN_SECRET_TOKENS (più token possono essere separati da virgola) e quindi si può fare una chiamata come segue:

ADMIN_SECRET_TOKEN=codice_segreto
[email protected]
amountCents=100 # centesimi
description="pagamento paypal"
curl "http://localhost:3000/graphql" -H "Authorization: ${ADMIN_SECRET_TOKEN}" -H "content-type: application/json" --data-raw '{"operationName":"SaveTransaction","variables":{"email":"'"${email}"'","amountCents":'"${amountCents}"',"description":"'"${description}"'"},"query":"mutation SaveTransaction($email: String, $amountCents: Int, $description: String) { transaction(email: $email\n amountCents:$amountCents\n  description: $description) }"}'
