A point of sales system made with NextJs, Prisma and CockroachDB.

I am using this project to learn more about Nextjs and how SSR and ISR works. This is my first time overall to using the next environment.

1. Record products with barcodes or not.
2. Creates and scans QR codes and barcodes using your smartphone.
3. Track installments and Invoices.

• I saw that using an api barcode databases are not free and if they are, they have a limited bandwidth.

• Well this is self explanatory. Since I want to learn Next and what's so special about it, I tried making an app and possibly switch to it if I came to love it.

First, run the development server:

npm run dev
# or
yarn dev

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

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

The API uses the following libraries :

"@prisma/client": "^4.9.0",
"bcryptjs": "^2.4.3",
"next-auth": "^4.18.7",

API routes can be accessed on http://localhost:3000/api. This endpoint can be edited in pages/api/*.

The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.

1. Logo
2. optimize addProduct on /api/product.ts. It takes 1.5s to create a product
3. optimize installments on /api/installment.ts. It takes 500ms to create,update and delete an installment
4. css minify
5. Qr code on generate barcode.
6. loading screen when a Link is pressed
7. edit product barcode on admin panel
8. react double mounting on qr code (use current)
