Database with PostgreSQL & Prisma

Robust, scalable database solution with type-safe ORM

Why PostgreSQL and Prisma?

The perfect combination for modern application data management

PostgreSQL is a robust, open-source relational database, perfect for complex data models in e-commerce (orders, products) and social media (users, posts). It offers excellent performance, ACID compliance, and advanced features like JSON support and full-text search.

Prisma simplifies database operations with a TypeScript-friendly ORM, generating type-safe queries for Hono.js APIs. Chosen for scalability, reliability, and your prior experience with PostgreSQL and Prisma in full-stack projects.

Usage in Hono.js API

import { PrismaClient } from '@prisma/client'

const prisma = new PrismaClient()

// Get all products
app.get('/api/products', async (c) => {
  const products = await prisma.product.findMany({
    include: {
      reviews: {
        select: {
          rating: true
        }
      }
    }
  })
  return c.json(products)
})

// Create new order
app.post('/api/orders', async (c) => {
  const { userId, items } = await c.req.json()
  
  const order = await prisma.order.create({
    data: {
      userId,
      items: {
        create: items
      }
    },
    include: {
      items: {
        include: {
          product: true
        }
      }
    }
