aux4/faker

Generate fake data for testing, mocking APIs, and populating databases.

aux4/faker leverages the Faker.js library to generate realistic fake data. It provides two main commands: fake value for generating individual values and fake object for generating or transforming JSON objects with fake data.

Installation

aux4 aux4 pkger install aux4/faker

Quick Start

Generate a fake email:

> aux4 fake value internet --type email

john.doe@example.com

Generate a fake person object:

> aux4 fake object --config person

{
  "firstName": "Maria",
  "lastName": "Johnson",
  "email": "maria.johnson@hotmail.com"
}

Commands

aux4 fake value

Generate individual fake values.

aux4 fake value <category> --type <type> [options]

Options:

--lang - Locale for generated data (default: en_US)
--type - Faker type within the category (e.g., firstName, email)
--count - Generate exactly N values (returns JSON array)
--min - Minimum number of values to generate
--max - Maximum number of values to generate
--arg - Arguments for the faker method (can be repeated)

aux4 fake object

Generate fake objects or transform existing JSON with fake data.

aux4 fake list

List faker categories and types.

aux4 fake list [category] [--type <type>]

Options:

category - Faker category (e.g., person, internet). If omitted, lists all categories.
--type - Filter by specific type (e.g., firstName, email)

aux4 fake object --config <name> [options]

Options:

--lang - Locale for generated data (default: en_US)
--config - Name of the mapping configuration in config.yaml
--count - Generate exactly N objects (returns JSON array)
--min - Minimum number of objects to generate
--max - Maximum number of objects to generate

Examples

Generate Single Values

Generate a first name:

> aux4 fake value person --type firstName

Michael

Generate a UUID:

> aux4 fake value string --type uuid

f47ac10b-58cc-4372-a567-0e02b2c3d479

Generate a random integer between 1 and 100:

> aux4 fake value number --type int --arg min=1 --arg max=100

Generate Multiple Values

Generate 3 email addresses:

> aux4 fake value internet --type email --count 3

["alex.smith@gmail.com", "sarah.jones@yahoo.com", "mike.wilson@hotmail.com"]

Generate between 2 and 5 random words:

> aux4 fake value lorem --type word --min 2 --max 5

["dolor", "ipsum", "amet"]

Passing Arguments to Value

Use --arg to pass arguments to faker methods. Arguments can be positional or named.

Positional argument

For methods that accept a single value:

> aux4 fake value person --type firstName --arg male

James

Named arguments

For methods with multiple options, use key=value format:

> aux4 fake value number --type int --arg min=1 --arg max=10

> aux4 fake value string --type alpha --arg length=8 --arg casing=upper

Generate Objects

Create a config.yaml file with your mapping definitions:

config:
  person:
    mapping:
      firstName:
        fake: person firstName
      lastName:
        fake: person lastName
      email:
        fake: internet email

Generate a person object:

> aux4 fake object --config person

{
  "firstName": "Emma",
  "lastName": "Davis",
  "email": "emma.davis@example.org"
}

Generate 3 person objects:

> aux4 fake object --config person --count 3

[
  { "firstName": "James", "lastName": "Brown", "email": "james.brown@gmail.com" },
  { "firstName": "Olivia", "lastName": "Miller", "email": "olivia.miller@yahoo.com" },
  { "firstName": "William", "lastName": "Taylor", "email": "william.taylor@hotmail.com" }
]

Transform Existing JSON

You can pipe existing JSON data and add fake fields to it. Original fields are preserved.

config:
  addEmail:
    mapping:
      email:
        fake: internet email

Transform a single object

> echo '{"id":1,"name":"John"}' | aux4 fake object --config addEmail

{
  "id": 1,
  "name": "John",
  "email": "john.doe@example.com"
}

Transform an array of objects

> echo '[{"id":1},{"id":2},{"id":3}]' | aux4 fake object --config addEmail

[
  { "id": 1, "email": "alex@gmail.com" },
  { "id": 2, "email": "sarah@yahoo.com" },
  { "id": 3, "email": "mike@hotmail.com" }
]

Transform NDJSON (newline-delimited JSON)

> printf '{"id":1}\n{"id":2}\n{"id":3}\n' | aux4 fake object --config addEmail

{"id":1,"email":"john@example.com"}
{"id":2,"email":"jane@example.org"}
{"id":3,"email":"bob@example.net"}

Mapping Formats

There are two formats for defining fake data in mappings.

String format (simple)

firstName:
  fake: person firstName

Object format (with arguments)

age:
  fake:
    category: number
    type: int
    args:
      min: 18
      max: 65

Arguments in Mappings

Pass arguments to faker methods using the args property.

Named arguments (as object)

config:
  user:
    mapping:
      age:
        fake:
          category: number
          type: int
          args:
            min: 18
            max: 65

> aux4 fake object --config user

{
  "age": 34
}

Array arguments

For methods like arrayElement that take an array as the first argument:

config:
  status:
    mapping:
      status:
        fake:
          category: helpers
          type: arrayElement
          args:
            - - pending
              - active
              - completed

> aux4 fake object --config status

{
  "status": "active"
}

Field References

Reference other fields in the same object using the @ prefix:

config:
  person:
    mapping:
      sex:
        fake:
          category: helpers
          type: arrayElement
          args:
            - - male
              - female
      firstName:
        fake:
          category: person
          type: firstName
          args:
            sex: "@sex"

> aux4 fake object --config person

{
  "sex": "female",
  "firstName": "Sophia"
}

References also work when transforming existing data - they can reference fields from the input:

> echo '{"sex":"male"}' | aux4 fake object --config person

{
  "sex": "male",
  "firstName": "James"
}

Nested Objects

Generate nested object structures:

config:
  user:
    mapping:
      name:
        fake: person fullName
      address:
        mapping:
          street:
            fake: location streetAddress
          city:
            fake: location city
          country:
            fake: location country

> aux4 fake object --config user

{
  "name": "John Smith",
  "address": {
    "street": "123 Main St",
    "city": "Boston",
    "country": "United States"
  }
}

Locale Support

Generate data in different locales:

> aux4 fake value person --type firstName --lang pt_BR

João

> aux4 fake value person --type firstName --lang de

Hans

> aux4 fake value person --type firstName --lang ja

太郎

Configuration

aux4/faker uses aux4/config to load mapping configurations. Create a config.yaml file with your mappings:

config:
  <name>:
    mapping:
      <field>:
        fake: <category> <type>

Reference a config by name using --config <name>.

Complete Example

Create a complete user dataset:

config.yaml:

config:
  fullUser:
    mapping:
      id:
        fake: string uuid
      firstName:
        fake: person firstName
      lastName:
        fake: person lastName
      email:
        fake: internet email
      age:
        fake:
          category: number
          type: int
          args:
            min: 18
            max: 80
      isActive:
        fake: datatype boolean
      joinedAt:
        fake: date past
      address:
        mapping:
          street:
            fake: location streetAddress
          city:
            fake: location city
          zipCode:
            fake: location zipCode

Generate 2 users:

> aux4 fake object --config fullUser --count 2

[
  {
    "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
    "firstName": "Emily",
    "lastName": "Johnson",
    "email": "emily.johnson@example.com",
    "age": 28,
    "isActive": true,
    "joinedAt": "2024-03-15T10:30:00.000Z",
    "address": {
      "street": "456 Oak Avenue",
      "city": "San Francisco",
      "zipCode": "94102"
    }
  },
  {
    "id": "b2c3d4e5-f6a7-8901-bcde-f23456789012",
    "firstName": "Michael",
    "lastName": "Williams",
    "email": "michael.williams@example.org",
    "age": 45,
    "isActive": false,
    "joinedAt": "2023-11-20T15:45:00.000Z",
    "address": {
      "street": "789 Pine Street",
      "city": "New York",
      "zipCode": "10001"
    }
  }
]
