Schema-Rand

schema-rand is a lightweight Node.js package for generating random mock data based on a given schema. It’s designed to simplify the process of creating test data for development and testing purposes.

Features

• 🛠️ Easy to Use: Define a schema and get random data in seconds.
• 🎲 Randomized Values: Generates random numbers, strings, booleans, and arrays.
• 🔄 Supports Nested Schemas: Handles deeply nested objects.
• 🚀 Lightweight: Simple and focused on testing needs.

Installation

Install the package via npm:

npm install schema-rand

example

const GetRand = require("schema-rand");

const schema = {
  id: "number",
  name: "string",
  isActive: "boolean",
  profile: {
    bio: "string",
    age: "number",
    address: {
      city: "string",
      zip: "number",
    },
  },
  tags: ["string"],
};

const result = GetRand(schema);

console.log("Size of Schema:", result.size);
console.log("Random Data:", result.randomValues);

output

Size of Schema: 7
Random Data: {
  id: 42,
  name: "abc123",
  isActive: true,
  profile: {
    bio: "xyz456",
    age: 29,
    address: {
      city: "qwe789",
      zip: 65
    }
  },
  tags: ["lmn101"]
}

How it works ?

Define a schema with key-value pairs. The values should be the expected data type (number, string, boolean, array, or object). Pass the schema to the GetRand function. Receive an object with randomly generated data matching the schema structure.

Limitations

Not suitable for production use. Does not validate schemas or ensure strict typing. Limited to basic types (number, string, boolean, array, object).
