Blueprint

This project is built on top of FakerJS and its main goal is to provide a schema-driven data generation in a very similar way we use schemas in NoSQL databases (one in particular comes to mind, maybe? 👀).

import { Blueprint as Bp } from '@cicerotcv/blueprint'

// you can describe schemas
const dateSchema = Bp.date
  .between("2000-01-01", "2022-12-31")
  .transform((date) => date.toISOString());

const idSchema = Bp.datatype.uuid();

const emailSchema = Bp.internet.email()

// join them together in a ObjectSchema
const userSchema = Bp.object({
  id: idSchema,
  createdAt: dateSchema,
  email: emailSchema,
});

// create an array of items of same kind
const userCollection = Bp.array({
  minLength: 1,
  maxLength: 4,
  schema: userSchema,
});

// and run .compile() to generate all the items
console.log(userCollection.compile());
