Description

This is a collection of useful modules on creating a Nest project. Mostly all of this modules are used by the in-house boilerplate of Web & Söhne.

Modules

Filters

GraphQL Error Parser

Since nest.js lets GraphQL handle its errors its own way, graphqlErrorParser is just a function instead of a filter. This will format the errors in the same way of the HTTP errors so you can also throw HTTP_STATUS errors instead of plain GraphQLError for more distinction and using the status code directly in the frontend. It will also add the GraphQL error field of which field this error is coming from.

Usage

Just add the error parser to the GraphQL Module itself.

import { GraphQLModule } from '@nestjs/graphql'
import { GraphQLErrorParser } from '@webundsoehne/nestjs-util-graphql'
import { Module } from '@nestjs/common'

@Module({
  imports: [
    GraphQLModule.forRoot({
      formatError: GraphQLErrorParser
    })
  ]
})
export class ServerModule {}
