Lot of "XXX declared but its value is not used" when generating client

[jeromeSH26]

hi everyone, when running yarn tsc, I'm getting a lot of errors/warning about "'xxx' is declared but its value is never read" after generating the typegraphql files, altough I have excluded the folder generated/typegraphql in my TSCONFIG file.

Have more than 3K errors as I have introspected an existing schema. So I can not fixed this issue manually for any generation of the client.

How do you manage this issue? Is there a specific config in your TSCONFIG.JSON ? I have manage warning in ESLINT by adding some rules, but what about TSC?

THls, I'm a great fan of type-graphql that I used to use together with typeorm

my TSCONFIG.JSON

}

the schema.prisma file

generator client {
  provider = "prisma-client-js"
  output   = "../src/generated/client"
}

generator typegraphql {
  provider               = "typegraphql-prisma"
  output                 = "../src/generated/typegraphql"
  customPrismaImportPath = "./../client"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

Have you tried "noUnusedLocals": false?

[shellscape]

This isn't an ideal solution as it affects the entire project. For projects which have this setting turned on explicitly, this is non-optimal.

[jeromeSH26]

yes better, have also set "noUnusedParameters": false to fix some other issue.
Now, I have an error when type-graphql is generating the schema. Some Input classes are empty

worth to mention that these 4 tables "Articles_fonctions, "Articles_magasin", are M-N Tables for relationships..

D:\devs\prismapoc\node_modules\type-graphql\dist\schema\schema-generator.js:20
                throw new errors_1.GeneratingSchemaError(errors);
                      ^
