npm install prisma-common-error-handle

Prisma common error handle

install

- npm i prisma-common-error-handle

Why I made this?

- When using Prisma in Nest.js 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 HTTP status Code 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.
- This library supports All PrismaClientKnowRequestError.

examples

- Below is an example used by the exception filter in Nest.js.
- You can call the function to get the message and HTTP Status Code and handle the exception according to each framework.
- Exception type must be PrismaClientKnownRequestError

``

typescript

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();

    const request = ctx.getRequest();

    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

typescript

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