Optimizers

A collection of minimal, dependency-free, performance-focused utilities for improving and compressing code or data in modern web and edge environments.

Overview

Optimizers provides safe, auditable modules designed to make code smaller and faster without unsafe parsing or heavy dependencies. Each tool focuses on a single responsibility and runs without build steps or runtime polyfills.

Available modules:

• is-dataset-minify — High-performance dataset optimizer for JSON, JSONL, and CSV.
  

• is-google-tag — Optimizes Google Tag for async, non-blocking, privacy-safe loading.
  

• is-html-minify — Safe HTML minifier that removes comments and collapses whitespace while preserving <pre>, <textarea>, <script>, and <style> content.
  

• is-minify — Safe, dependency-free JavaScript and CSS minifier for browser and Node.
  

• is-prompt-minify — Compact large language model (LLM) prompts by removing redundancy, extra whitespace, and repeated phrases without altering meaning.
  

• is-strip-ansi — Removes ANSI escape sequences (color codes, control characters) from strings safely.
  

All helpers are designed for use in:

• Browsers (ESM)
• Node.js / Deno / Bun
• Edge runtimes (Cloudflare Workers, Vercel Edge, etc.)

Each module has its own README.md, tests, and can be imported individually.

🔗 Live Demos (GitHub Pages)

You can try each validator interactively in your browser:

• Dataset Optimizer Test
• Google Tag Demo
• html Minification Demo
• JS/CSS Minification Demo
• Prompt Minify Demo
• Strip ANSI Demo

Each page loads its respective module and allows interactive validation.

Install

npm i @yvancg/optimizers

or per-module packages when published

API Guarantees

• No eval or dynamic code.
• No untrusted regular expressions.
• Deterministic output with consistent whitespace and comment removal.

Design Principles

1. Safety first: Never execute or interpret arbitrary code during optimization.
2. No dependencies: All logic is pure ESM JavaScript.
3. Performance: Runs in O(n) time on typical input.
4. Portability: Works the same in browser, Node, and edge runtimes.
5. Transparency: Fully open-source, easy to audit.

Example Usage

import { optimizeDataset } from './is-dataset/dataset.js';
import { optimizeGTag } from './is-google-tag/gtag.js';
import { minifyHTML }   from './is-html-minify/html.js';
import { minifyJS, minifyCSS } from './is-minify/minify.js';
import { promptMinify } from './is-prompt-minify/prompt.js';
import { stripAnsi } from './is-strip-ansi/strip.js';

console.log(generateDataset({ count: 3, format: 'jsonl', seed: 'demo' }));
// → '{"id":"...","text":"Lorem ipsum ..."}'

console.log(
  optimizeDataset(
    '[{"id":1,"Text":"  Hello   world  "},{"id":1,"Text":"Hello world"}]',
    { format: 'json', keyCase: 'snake', dropDuplicateRows: true }
  )
);
// → '[{"id":1,"text":"Hello world"}]'

console.log(optimizeGTag('<script src="https://www.googletagmanager.com/gtag/js?id=G-TEST"></script>'));
// → optimized, async, privacy-safe version of the tag

console.log(minifyHTML(`
  <!-- comment -->
  <div class="box">
    <p> Hello   world </p>
    <pre> keep   this   </pre>
    <script> const x =  1 + 2 </script>
  </div>
`));
// → '<div class="box"><p>Hello world</p><pre> keep   this   </pre><script> const x =  1 + 2 </script></div>'

console.log(minifyJS('function x () { return 1 + 2 ; }'));
// → 'function x(){return 1+2;}'

console.log(minifyCSS('body { color : red ; }'));
// → 'body{color:red;}'

console.log(promptMinify('You are a helpful helpful AI assistant. Please please respond clearly clearly.'));
// → 'You are a helpful AI assistant. Please respond clearly.'

console.log(stripAnsi('\u001B[31mError:\u001B[0m invalid token'));
// → 'Error: invalid token'

Security Notes

• No dynamic code execution or new Function() calls.
• All regexes are tested for ReDoS safety.
• Produces deterministic minified output safe for sandboxed environments.

Contributing

Pull requests for additional safe validators (e.g., IBAN, domain names, etc.) are welcome. Please maintain the following rules:

• Pure functions only (no side effects)
• No external dependencies
• 100% test coverage for new logic
• TypeScript or plain ESM JavaScript
