| 1 | +# Quick Mock Data Generator |
| 2 | + |
| 3 | +Need test data quickly? This lightweight utility helps you generate realistic mock data in seconds. Choose from common properties like names, emails, and dates, **or define your own generators**. Perfect for prototypes, tests, and demos where you need meaningful data fast. |
| 4 | + |
| 5 | +Built on top of `@faker-js/faker`, it provides a simpler interface while maintaining type safety and full TypeScript support. |
| 6 | + |
| 7 | +Key features: |
| 8 | +- 🚀 Quick property selection from common data types |
| 9 | +- 🎯 Generate exactly what you need, nothing more |
| 10 | +- 📦 Zero configuration required |
| 11 | +- 🔍 Full TypeScript support with autocompletion |
| 12 | + |
| 13 | +## Installation |
| 14 | + |
| 15 | +### Using Deno |
| 16 | + |
| 17 | +```sh |
| 18 | +deno add @functions/mock |
| 19 | +``` |
| 20 | + |
| 21 | +### Using npm / pnpm / or others |
| 22 | + |
| 23 | +```sh |
| 24 | +npx jsr add @functions/mock |
| 25 | +pnpm dlx jsr add @functions/mock |
| 26 | +yarn dlx jsr add @functions/mock |
| 27 | +bunx jsr add @functions/mock |
| 28 | +``` |
| 29 | + |
| 30 | +## Usage |
| 31 | + |
| 32 | +### Generate Mock Data with Specific Properties |
| 33 | + |
| 34 | +The `getMocksWith` function allows you to pick from a predefined set of common properties (like name, email, age, avatar, etc.) and quickly generate objects containing just those properties. Perfect for creating test data with exactly what you need in a fast way: |
| 35 | + |
| 36 | +This basically returns a function that will create mock data based on a list of predefined properties. |
| 37 | + |
| 38 | + |
| 39 | +```typescript |
| 40 | +import { getMocksWith } from "@functions/mock"; |
| 41 | + |
| 42 | +// Autosuggestion will let you pick the properties you want in your mock objects |
| 43 | +const createRandomUsers = getMocksWith(['name', 'age', 'email']); |
| 44 | + |
| 45 | +// Generate 3 users with only those properties |
| 46 | +const users = createRandomUsers(3); |
| 47 | +``` |
| 48 | + |
| 49 | +### Generate Mock Data from a Generator |
| 50 | + |
| 51 | +The `getMocksFromGenerator` function preserves the types of your generator functions: |
| 52 | + |
| 53 | +```typescript |
| 54 | +import { getMocksFromGenerator } from "@functions/mock"; |
| 55 | +import { faker } from "@faker-js/faker"; |
| 56 | + |
| 57 | +const yourGenerator = { |
| 58 | + id: faker.string.uuid, |
| 59 | + name: faker.person.firstName, |
| 60 | + age: () => faker.number.int({ min: 18, max: 99 }), |
| 61 | +}; |
| 62 | + |
| 63 | +const createRandomObjects = getMocksFromGenerator(yourGenerator); |
| 64 | +// TypeScript infers exact return types from your generator functions |
| 65 | +const objects = createRandomObjects(5); |
| 66 | +// objects is typed as Array<{ id: string; name: string; age: number }> |
| 67 | +``` |
| 68 | + |
| 69 | + |
| 70 | + |
| 71 | +### `getMocksFromGenerator` |
| 72 | + |
| 73 | +Type-safe generator that creates mock data from a predefined generator. |
| 74 | + |
| 75 | +**Parameters:** |
| 76 | +- `gen`: An object where keys are property names and values are functions that generate the property values. Types are automatically inferred from your generator functions. |
| 77 | + |
| 78 | +**Returns:** |
| 79 | +- A strongly-typed function that generates an array of mock objects with exact property types. |
