NestJS gRPC Exceptions

This library provides RpcException wrappers for gRPC status codes.

``bash
pnpm add nestjs-grpc-exceptions
`

or

`bash
npm install nestjs-grpc-exceptions
`

or

`bash
yarn add nestjs-grpc-exceptions
`

First add the GrpcServerExceptionFilter to your gRPC server:

`ts
import { Module } from "@nestjs/common";
import { APP_FILTER } from "@nestjs/core";
import { GrpcServerExceptionFilter } from "nestjs-grpc-exceptions";

@Module({
providers: [
{
provide: APP_FILTER,
useClass: GrpcServerExceptionFilter,
},
],
})
export class UserModule {}
`

Add the client interceptor to your client:

`ts
import { GrpcToHttpInterceptor } from 'nestjs-grpc-exceptions';

@Get(':id')
@UseInterceptors(GrpcToHttpInterceptor)
function findUser(@Param('id') id: number): void;
`

Now you can use the exception classes in your servers:

`ts
import {
GrpcNotFoundException,
GrpcInvalidArgumentException,
} from "nestjs-grpc-exceptions";

throw new GrpcNotFoundException("User Not Found.");
throw new GrpcInvalidArgumentException("input 'name' is not valid.");
`

If you use Http Exceptions in your microservice clients, you can use the HttpToGrpcInterceptor interceptor to convert them

`ts
import { HttpToGrpcInterceptor } from 'nestjs-grpc-exceptions';

@UseInterceptors(HttpToGrpcInterceptor)
@GrpcMethod()
function getAllUsers(): void;
``
