Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Quick Start

import { Synthik } from '@synthik/sdk';

const synthik = new Synthik({
  privateKey: 'YOUR_PRIVATE_KEY',
  network: 'calibration', // or 'mainnet'

  // Add AI model API keys for dataset generation
  apiKeys: {
    openai: 'YOUR_OPENAI_API_KEY', // For GPT models
    google: 'YOUR_GOOGLE_API_KEY', // For Gemini models
  },

  storage: {
    provider: 'mock', // Use 'ipfs' or 'filecoin' for production
  },
});

// Generate a dataset using AI
const models = synthik.getAvailableModels();
const dataset = await synthik.generateDataset(
  {
    name: 'My E-commerce Dataset',
    description: 'Synthetic e-commerce data',
    rows: 1000,
    schema: [
      { name: 'order_id', type: 'string', description: 'Order ID' },
      { name: 'customer_name', type: 'string', description: 'Customer name' },
      { name: 'price', type: 'number', description: 'Price in USD' },
      // ... more fields
    ],
  },
  models[0]
);

console.log(`Generated dataset: ${dataset.id}`);

AI Dataset Generation

The SDK supports generating synthetic datasets using OpenAI GPT and Google Gemini models. Simply provide your API keys and define your schema.

Getting Started with AI Generation

// 1. Check available models
const models = synthik.getAvailableModels();
console.log(
  'Available models:',
  models.map((m) => m.name)
);

// 2. Generate a preview first (10 rows)
const preview = await synthik.generatePreview(config, models[0]);
console.log('Preview data:', preview);

// 3. Generate the full dataset
const dataset = await synthik.generateDataset(config, models[0], {
  onProgress: (progress, message) => {
    console.log(`${Math.round(progress)}%: ${message}`);
  },
});

Supported AI Models

| Provider | Model | Cost/Token | Max Tokens | Best For | | -------- | ---------------- | ---------- | ---------- | ------------------------------- | | OpenAI | GPT-4o Mini | $0.00015 | 16,000 | Fast, cost-effective generation | | OpenAI | GPT-4o | $0.0025 | 128,000 | High-quality, complex datasets | | Google | Gemini 1.5 Flash | $0.00007 | 32,768 | Ultra-fast generation | | Google | Gemini 1.5 Pro | $0.00125 | 32,768 | Best quality, complex schemas |

Schema Definition

const ecommerceSchema: SchemaField[] = [
  {
    name: 'order_id',
    type: 'string',
    description: 'Unique order identifier',
    constraints: {
      required: true,
      unique: true,
      pattern: '^ORD-[0-9]{8}$', // Regex pattern
    },
  },
  {
    name: 'customer_email',
    type: 'string',
    description: 'Customer email address',
    constraints: {
      required: true,
      pattern: '^[\\w\\._%+-]+@[\\w\\.-]+\\.[A-Za-z]{2,}$',
    },
  },
  {
    name: 'price',
    type: 'number',
    description: 'Product price in USD',
    constraints: {
      required: true,
      min: 1.0,
      max: 10000.0,
    },
  },
  {
    name: 'category',
    type: 'string',
    description: 'Product category',
    constraints: {
      required: true,
      enum: ['Electronics', 'Clothing', 'Books', 'Home', 'Sports'],
    },
  },
  {
    name: 'order_date',
    type: 'date',
    description: 'When the order was placed',
    constraints: { required: true },
  },
];

      constraints: { required: true, min: 50, max: 100000 },
    },
  ],
  quality: 'high',
  visibility: 'private',
};

Financial Dataset

  name: 'Banking Transactions',
  description: 'Synthetic banking transaction data',
  rows: 5000,
  schema: [
    {
      name: 'transaction_id',
      type: 'string',
      description: 'Unique transaction identifier',
      constraints: { required: true, unique: true },
    },
    {
      name: 'account_number',
      type: 'string',
      description: 'Bank account number (masked)',
      constraints: { required: true, pattern: '^****[0-9]{4}$' },
    },
    {
      name: 'transaction_type',
      type: 'string',
      description: 'Type of transaction',
      constraints: {
        required: true,
        enum: ['deposit', 'withdrawal', 'transfer', 'payment', 'fee'],
      },
    },
    {
      name: 'amount',
      type: 'number',
      description: 'Transaction amount in USD',
      constraints: { required: true, min: 0.01, max: 1000000 },
    },
  ],
  quality: 'balanced',
};

Generation Quality Levels

  • fast: Optimized for speed, simpler patterns
  • balanced: Good balance of quality and speed (recommended)
  • high: Maximum quality, more complex relationships

Export and Use Generated Data

// Generate the dataset
const dataset = await synthik.generateDataset(config, model);

// Download the raw data
const data = await synthik.storage.downloadJSON(dataset.dataCid);

// Export in different formats
const csvBlob = synthik.datasets.exportData(data, 'csv');
const jsonBlob = synthik.datasets.exportData(data, 'json');

// Create download links (browser)
const csvUrl = URL.createObjectURL(csvBlob);
const downloadLink = document.createElement('a');
downloadLink.href = csvUrl;
downloadLink.download = 'synthetic-data.csv';
downloadLink.click();

Cost Estimation

// Estimate generation cost before running
const estimatedTokens = config.rows * config.schema.length * 50; // Rough estimate
const estimatedCost = estimatedTokens * model.capabilities.costPerToken;

console.log(`Estimated cost: $${estimatedCost.toFixed(4)}`);
console.log(`Estimated tokens: ${estimatedTokens.toLocaleString()}`);

Best Practices for AI Generation

  1. Start Small: Always generate a preview first
  2. Schema Design: Be specific in field descriptions
  3. Use Constraints: Leverage min/max, patterns, and enums
  4. Quality vs Speed: Choose appropriate quality level
  5. Cost Management: Monitor token usage for large datasets
  6. Privacy First: Use anonymization for sensitive data types
