NestJS GraphQL Mix

NestJS + GraphQL(code first) + Prisma, Help you to implement the Prisma template interface as a GraphQL(code first) Type classes. 🎉Fast work!

Installation

Via NPM:

npm i @bytegem/nest-gql-mix

Or via Yarn:

yarn add  @bytegem/nest-gql-mix

Using

Before using this package:

@InputType({ description: 'This is User where input' })
export class UserWhereInput implements Prisma.UserWhereInput {
  @Field((type) => [UserWhereInput], { nullable: true })
  AND?: UserWhereInput[];

  @Field((type) => [UserWhereInput], { nullable: true })
  OR?: UserWhereInput[];

  @Field((type) => [UserWhereInput], { nullable: true })
  NOT?: UserWhereInput[];

  @Field((type) => StringFilter, { nullable: true })
  id?: StringFilter;

  @Field((type) => StringFilter, { nullable: true })
  username?: StringFilter;

  @Field((type) => StringFilter, { nullable: true })
  email?: StringFilter;

  @Field((type) => StringFilter, { nullable: true })
  phone?: StringFilter;

  /// More fields...

Now:

@InputTypeBuilder(
  { description: 'User where input' },
  FieldsBuilderOptionHelper(
    ['id', 'username', 'email', 'phone', /* ...more fields */],
    () => StringFilter,
    { nullable: true },
  ),
)
export class UserWhereInput extends InterfaceTransformAbstract<Prisma.UserWhereInput>>() {}

extends InterfaceTransformAbstract<T>() is optional. After adding it, you can prompt the IDE code when you actively use this class. Not inheriting has no effect on the actual operation.

Decorators

• ArgsTypeBuilder: The ArgsType class builder.
  • FindFirstArgsBuilder: Fast build Prisma ${Model}FindFirst args class.
  • FindManyArgsBuilder: Fast build Prisma ${Model}FindMany args class.
• InputTypeBuilder: The InputType class builder.
  • WhereInputTypeBuilder: Fast build Prisma ${Model}WhereInput input class.
  • RelationFilterBuilder: Fast build Prisma ${Model}ListRelationFilter input class.
• InterfaceTypeBuilder: The InterfaceType class builder.
• ObjectTypeBuilder: The ObjectType class builder.

Helpers

• FieldsBuilderOptionHelper: Passing [Args|Object|Input|Interface]TypeBuilder parameters does not simplify much code work. For multiple fields with the same FieldOptions, you can use this tool to quickly generate.

Transforms

• InterfaceTransformAbstract: You can transform the interface class into an abstract class to help IDE with code hints.
