Define a pagination input type:

pagination.input.ts

@InputType()
export class Pagination {
  @Field(() => Int, { defaultValue: 0 })
  skip: number;

  @Field(() => Int, { defaultValue: 10 })
  take: number;
}

users.resolver.ts

import { Args, Query, Resolver } from '@nestjs/graphql';
import { PaginationInput } from './pagination.input';
import { UsersService } from './users.service';

@Resolver()
export class UsersResolver {
  constructor(private usersService: UsersService) {}

  @Query(() => [User])
  async getUsers(@Args('pagination') pagination: PaginationInput) {
    const { skip, take } = pagination;
    return this.usersService.getUsers(skip, take);
  }
}
