swift-optimizer

A platform-specific code optimization engine for JavaScript/TypeScript with native binary support.

swift-optimizer automatically detects your system's OS and CPU architecture, then downloads and manages the appropriate pre-compiled optimization binary during installation. This enables system-specific performance tuning and code optimization operations.

Similar to: esbuild (optimization), Puppeteer (binary management), Playwright (platform detection)

Features

• ✅ Automatic Platform Detection - Detects OS, CPU architecture, Node version
• ✅ Platform-Specific Binaries - Windows (x64, arm64), macOS (x64, arm64), Linux (x64, arm64, ia32)
• ✅ Postinstall Binary Management - Automatically installs correct binary during npm install
• ✅ Checksum Verification - Validates binary integrity using SHA256
• ✅ Manifest Tracking - Records installation metadata and platform info
• ✅ Fallback Support - Graceful degradation if binary unavailable
• ✅ TypeScript Support - Full type definitions included
• ✅ Cross-Platform - Works on Windows, macOS, and Linux

Installation

Prerequisites

• Node.js 14+ (LTS recommended)
• npm (included with Node.js)

Setup

npm install swift-optimizer

During installation, swift-optimizer will:

1. Detect your platform and architecture
2. Verify Node.js and OS compatibility
3. Download the appropriate platform-specific binary
4. Verify binary integrity with SHA256
5. Create installation manifest

Usage

Basic Setup

import { createOptimizer } from 'swift-optimizer';

const optimizer = createOptimizer();
const status = optimizer.getStatus();

Platform Information

import { BinaryLocator } from 'swift-optimizer';

const locator = new BinaryLocator();
const info = locator.getPlatformInfo();

Code Optimization

import { Optimizer } from 'swift-optimizer';

const optimizer = new Optimizer();
const optimized = optimizer.optimize(code, { level: 3 });

Detailed Report

const optimizer = createOptimizer();
const report = optimizer.getReport();

Supported Platforms

API Reference

BinaryLocator

class BinaryLocator {
  platform: string;              
  arch: string;                  
  binaryName: string;           
  binaryPath: string;            

  isBinaryAvailable(): boolean;
  getPlatformInfo(): Record<string, any>;
  getManifest(): Record<string, any> | null;
}

Optimizer

class Optimizer {
  getStatus(): { ready: boolean; platform: string; architecture: string; binaryFound: boolean };
  initialize(): void;
  optimize(code: string, options?: { level?: number; target?: string }): string;
  getReport(): Record<string, any>;
}

Troubleshooting

If you see "swift-optimizer binary not found", try:

npm install swift-optimizer
