"Utilizing GroupBy and Sum functions for data aggregation in Prisma

I am currently working with a Prisma schema designed for a MongoDB database

model orders {
  id             String              @id @default(auto()) @map("_id") @db.ObjectId
  totalAmount    Int
  createdAt      DateTime            @db.Date
}

My goal is to perform a groupby operation based on dates, and calculate the sum of total amounts on a monthly basis. For example:

{
  "January": 4567,
   "February": 7785
}

I attempted to achieve this using the method provided in the documentation, but unfortunately, it did not work as expected:

const sales = await prisma.orders.groupBy({
    by: ["createdAt"],
    _sum: {
      totalAmount: true,
    },
    orderBy: { createdAt: "desc" },
  });

Can someone guide me on how I can successfully accomplish this task?

It appears that Prisma does not currently offer a solution for this issue. In order to achieve the desired outcome, I utilized Prisma to retrieve data from MongoDB and then performed the necessary grouping and summing operations in JavaScript.

const { PrismaClient } = require('@prisma/client');

const prisma = new PrismaClient();

async function sumTotalAmountByMonth() {
  const orders = await prisma.orders.findMany();

  const salesByMonth = orders.reduce((result, { createdAt, totalAmount }) => {
    const month = createdAt.toLocaleString('default', { month: 'long' });
    result[month] = (result[month] || 0) + totalAmount;
    return result;
  }, {});

  return salesByMonth;
}

sumTotalAmountByMonth()
  .then((salesByMonth) => console.log(salesByMonth))
  .catch((error) => console.error(error))
  .finally(() => prisma.$disconnect());

If you're ever in need of aggregating data with GroupBy using a sum, the Prisma documentation offers some helpful guidance on how to achieve this.

Check out the Prisma docs

While it may not directly address the issue of monthly aggregation, Prisma makes it easy to handle sum and grouping operations seamlessly.
