Faker is a PHP library that generates fake data for you
Faker is a Python package that generates fake data for you.
A data mapper for Node.js and PostgreSQL.
Quick Overview
generatedata is an open-source tool for generating custom, realistic test data for various purposes such as database population, software testing, and data analysis. It provides a user-friendly web interface and a powerful API for creating large volumes of mock data in multiple formats, including CSV, JSON, and SQL.
Pros
- Highly customizable with support for numerous data types and export formats
- User-friendly web interface for easy data generation without coding
- Extensible architecture allowing for custom plugins and data types
- Multi-language support for generating localized data
Cons
- Setup process can be complex for self-hosting
- Limited documentation for advanced features and customization
- Performance may degrade with very large datasets
- Some data types may require additional configuration or plugins
Code Examples
- Using the API to generate data:
const GenerateData = require('generatedata');
const config = {
numRows: 100,
rows: [
{ type: 'names', options: { gender: 'male' } },
{ type: 'email' },
{ type: 'age', options: { min: 18, max: 65 } }
],
export: { type: 'JSON' }
};
GenerateData.generate(config)
.then(data => console.log(data))
.catch(error => console.error(error));
- Creating a custom data type plugin:
const CustomDataType = {
name: 'customType',
generate: (options) => {
// Custom logic to generate data
return 'Generated Value';
},
getOptions: () => ({
// Define options for the data type
})
};
GenerateData.registerDataType(CustomDataType);
- Exporting data to SQL format:
const sqlConfig = {
numRows: 50,
rows: [
{ type: 'autoIncrement', options: { col: 'id' } },
{ type: 'names' },
{ type: 'email' }
],
export: {
type: 'SQL',
options: {
tableName: 'users',
databaseType: 'MySQL'
}
}
};
GenerateData.generate(sqlConfig)
.then(sqlData => console.log(sqlData))
.catch(error => console.error(error));
Getting Started
-
Install generatedata:
npm install generatedata
-
Import and use in your project:
const GenerateData = require('generatedata'); const config = { numRows: 10, rows: [ { type: 'names' }, { type: 'email' } ], export: { type: 'JSON' } }; GenerateData.generate(config) .then(data => console.log(data)) .catch(error => console.error(error));
-
Run the code to generate sample data.
Competitor Comparisons
Faker is a PHP library that generates fake data for you
Pros of Faker
- More extensive library of data types and locales
- Easier to integrate into existing PHP projects
- Better documentation and community support
Cons of Faker
- Limited to PHP language
- Less customizable data generation options
- No built-in GUI for quick data generation
Code Comparison
Faker:
$faker = Faker\Factory::create();
echo $faker->name;
echo $faker->email;
echo $faker->text;
generatedata:
import { init, generate } from 'generatedata';
const data = await generate({
numRows: 10,
rows: [{ type: 'names' }, { type: 'email' }]
});
Summary
Faker is a popular PHP library for generating fake data, offering a wide range of data types and locales. It's easy to integrate into existing PHP projects and has excellent documentation. However, it's limited to PHP and lacks a GUI for quick data generation.
generatedata, on the other hand, is a more versatile tool that supports multiple programming languages and offers a web-based interface for generating data. It provides more customization options but may have a steeper learning curve for simple use cases.
Choose Faker for PHP-specific projects with straightforward data generation needs, and generatedata for multi-language support or when you need a GUI for data creation.
Faker is a Python package that generates fake data for you.
Pros of Faker
- More extensive library with a wider range of data types and providers
- Better support for internationalization and localization
- Actively maintained with frequent updates and contributions
Cons of Faker
- Requires more setup and configuration for complex data generation
- Less intuitive for non-programmers or those unfamiliar with Python
- May be overkill for simple data generation tasks
Code Comparison
Faker:
from faker import Faker
fake = Faker()
print(fake.name())
print(fake.email())
print(fake.address())
Generatedata:
const generatedata = require('generatedata');
const data = generatedata.generate({
numRows: 1,
rows: [
{ type: 'Names' },
{ type: 'Email' },
{ type: 'Street Address' }
]
});
console.log(data);
Both libraries offer ways to generate fake data, but Faker provides a more straightforward API for individual data types, while Generatedata focuses on generating structured datasets. Faker is more flexible for programmatic use, while Generatedata may be easier for creating larger datasets with specific structures.
A data mapper for Node.js and PostgreSQL.
Pros of massive-js
- Focused on database operations, providing a robust ORM for PostgreSQL
- Supports advanced PostgreSQL features like JSON operations and full-text search
- More suitable for production-grade applications with complex data requirements
Cons of massive-js
- Limited to PostgreSQL, while generatedata supports multiple database types
- Steeper learning curve compared to generatedata's user-friendly interface
- Lacks built-in data generation capabilities, which is generatedata's primary function
Code Comparison
massive-js:
const massive = require('massive');
const db = await massive({
host: 'localhost',
port: 5432,
database: 'mydb',
user: 'myuser',
password: 'mypassword'
});
generatedata:
const generatedata = require('generatedata');
const data = generatedata.generate({
numRows: 100,
dataType: 'names',
country: 'US'
});
Summary
While massive-js is a powerful ORM for PostgreSQL, generatedata is specifically designed for generating mock data across various database types. massive-js is better suited for complex database operations in production environments, whereas generatedata excels in creating test data quickly and easily. The choice between the two depends on the specific needs of your project: database management and querying (massive-js) or mock data generation (generatedata).

generatedata.com
This is the repo for the downloadable version of generatedata.com. The script is essentially an engine to generate any sort of random data in any format. It currently comes with 30 or so Data Types (types of data it generates), 12 Export Types (formats for the data, like CSV, SQL, JSON), plus around 32 data sets for specific countries (city names, regions etc). But more importantly it can be extended in any way you want. Check out the developer documentation for more information on that.
Programmatic generation
The current major version of the script is 4.x, which was a big change over earlier releases. Earlier versions were written in PHP and MYSQL and 3.x offered a REST API to let you generate the data programmatically rather than via an API. While this is still planned for 4.x it's not currently offered, and the plan it to tackle that after making the script available as an npm package - which we feel will be a more convenient way to programmatically generate data over the more agnostic REST approach.
Requirements
- Docker
- node
- nvm
