Prisma common error handle

install

• npm i prisma-common-error-handle

Why I made this?

• When using prisma in nestjs or express or other frameworks, there are cases where exceptions that prisma throw are filtered.
• At this time, the library was created to make it easier to deal with the most frequently occurring prisma errors, such as PrismaClientKnowRequestError.
• The findPrismaErrorInfo() function provides specific error messages and httpstatus that fit each Prisma error.
• In addition, the PrismaCommonErrCode enumeration contains a frequently used prisma error code.
• Each error message contains a detailed description of the error and a solution.

examples

• Below is an example used by the exception filter in nestjs.
• You can call the function to get the message and http status and handle the exception according to each framework.
• Exception type must be PrismaClientKnownRequestError

import { ArgumentsHost, Catch } from "@nestjs/common";
import { BaseExceptionFilter } from "@nestjs/core";
import { PrismaClientKnownRequestError } from "@prisma/client";
import { Request, Response } from "express";
import { findPrismaErrorInfo } from "prisma-common-error-handle";

@Catch(PrismaClientKnownRequestError)
export class PrismaClientExceptionFilter extends BaseExceptionFilter {
  catch(exception: PrismaClientKnownRequestError, host: ArgumentsHost) {
    const ctx = host.switchToHttp();
    const response = ctx.getResponse<Response>();
    const request = ctx.getRequest<Request>();
    const { message, status } = findPrismaErrorInfo(exception);

    response.status(status).json({
      message,
      statusCode: status,
      timestamp: new Date().toISOString(),
      path: request.url,
    });
  }
}

• simple example
• Exception type must be PrismaClientKnownRequestError

const { message, status } = findPrismaErrorInfo(exception);
