Show me how do you call Nano ID?

from nanoid.

import { customAlphabet } from 'nanoid'
nanoid = customAlphabet('1234567890abcdef', 10)
model.id = this.nanoid() //=> "4f90d13a42"

from nanoid.

Why it is this?

from nanoid.

I am unable to use const in front nanoid when declaring. This is how I am using it in my project. nanoid version (3.0.0)

import { customAlphabet } from 'nanoid';

@Injectable()
export class ProductOptionGroupService {
  nanoid = customAlphabet(process.env.NANOID_GEN, 8);
  constructor(
    @InjectModel(ProductGroupOptions)
    private productModel: typeof ProductGroupOptions,
  ) {}

  async create(adminId: string, dto: CreateProductOptGrpDto) {
    const product = await this.productModel.create({
      adminId,
      name: dto.name,
      createdb: adminId,
      code: this.nanoid(),
    });
    return product;
  }
}

from nanoid.

More likely that process.env.NANOID_GEN is empty.

Error tells that alphabet is undefined.

Yeah. It worked. Thanks alot. I forgot to add NANOID_GEN to the env
