Run your prisma migrations and you're ready to go!

Setup with default configs:

import { createLogger, format } from "winston";
import { PrismaClient } from "@prisma/client";
import { PrismaWinstonTransporter } from "winston-prisma-transporter";

const prisma = new PrismaClient();   
const logger = winston.createLogger({
  transports: [
    format: format.json(),
    new PrismaWinstonTransporter({
      level: "http",
      prisma
    }),
  ],
});

Customizations

Out of the box, the logger will log all levels to the Table called UserLog. That can be changed to a different table by passing in the custom table name.

import { createLogger, format } from "winston";
import { PrismaClient } from "@prisma/client";
import { PrismaWinstonTransporter } from "winston-prisma-transporter";

const prisma = new PrismaClient();   
const logger = winston.createLogger({
  transports: [
    format: format.json(),
    new PrismaWinstonTransporter({
      level: "http",
      prisma,
      tableName: "CustomTableName"
    }),
  ],
});

All options avaliable while initiating the transport:

export interface PrismaTransporterOptions extends TransportStreamOptions {
  prisma: PrismaClient;
  tableName?: string;
}
