A suite of Angular libraries that helps you build secure, browser-integrated applications with a clean developer experience.

Advanced regular expression security and ReDoS prevention

🌐 Documentation: https://gaspar1992.github.io/angular-helpers/docs/security

🎯 What it solves:

• ReDoS (Regular Expression Denial of Service) attacks caused by malicious or expensive patterns.
• Safe validation of complex regular expressions without blocking your app.
• Controlled regex execution with timeout and security analysis.

✨ Key features:

• 🛡️ ReDoS prevention with automatic risky pattern checks.
• ⚡ Web Worker execution to avoid blocking the main thread.
• 🕐 Configurable timeout to limit expensive regex operations.
• 📊 Risk analysis with complexity metrics and recommendations.
• 🏗️ Builder pattern for fluent secure-regex configuration.

💡 Example usage:

// Safe regex validation for user input
const result = await securityService.testRegex(userInput, text, {
  timeout: 5000,
  safeMode: true,
});

// Builder pattern for complex patterns
const { pattern, security } = RegexSecurityService.builder()
  .pattern('\\d+')
  .timeout(3000)
  .safeMode()
  .build();

📥 Installation:

pnpm add @angular-helpers/security

Unified and safe browser API access with permissions and robust error handling

🌐 Documentation: https://gaspar1992.github.io/angular-helpers/docs/browser-web-apis

🎯 What it solves:

• API fragmentation across browsers.
• Permission complexity for sensitive browser features.
• Compatibility checks that usually require repetitive boilerplate.
• Inconsistent error handling across web APIs.

✨ Key features:

• 📸 Camera access and stream control.
• 🗺️ Geolocation with watch support and typed errors.
• 🔔 Notifications with permission-aware behavior.
• 📋 Clipboard utilities.
• 🎥 Media Devices enumeration and media access.
• 🔐 Centralized permission utilities.
• ✅ Device/browser API wrappers with fallback checks.
• ⚡ Signal Fn primitives — 14 zero-boilerplate reactive inject functions (injectPageVisibility, injectResizeObserver, injectIntersectionObserver, injectNetworkInformation, injectScreenOrientation, injectMutationObserver, injectPerformanceObserver, injectIdleDetector, injectGamepad, injectClipboard, injectGeolocation, injectBattery, injectWakeLock, injectEyeDropper) with automatic cleanup and viewChild signal support.
• 🔒 Web Locks — Cross-tab resource coordination.
• 💾 Storage Manager — Storage quotas and persistence.
• 📦 Compression Streams — Gzip/deflate compression.

📥 Installation:

pnpm add @angular-helpers/browser-web-apis

Angular HTTP over Web Workers — off-main-thread HTTP pipelines

🌐 Documentation: https://gaspar1992.github.io/angular-helpers/docs/worker-http

🎯 What it solves:

• Main-thread blocking from heavy HTTP payloads and serialization.
• Request signing complexity with WebCrypto HMAC.
• Serialization overhead with pluggable format support.

✨ Key features:

• 🔀 Off-main-thread HTTP pipelines via Web Workers.
• 🔌 Typed RPC bridge for structured worker communication.
• 🔐 WebCrypto HMAC request signing.
• 📦 Pluggable serializers (TOON, seroval, auto-detect).
• 📡 Telemetry hooks for APM / metrics integration.
• 🌍 SSR + hydration — automatic fallback with transfer cache support.
• 🛠️ ng add schematic for zero-config setup.

📥 Installation:

pnpm add @angular-helpers/worker-http

A modern Angular wrapper for OpenLayers with modular architecture and standalone components

🌐 Documentation: https://gaspar1992.github.io/angular-helpers/docs/openlayers

🎯 What it solves:

• Imperative OpenLayers API — wraps it in declarative Angular components.
• Bundle bloat — modular sub-entry points import only what you need.
• Military mapping — ellipses, sectors, NATO symbology out of the box.

✨ Key features:

• 🗺️ Standalone components for maps, layers, controls, interactions, and overlays.
• 📡 Signals integration — native Angular signals for reactive state.
• 🎯 Modular loading — core, layers, controls, interactions, overlays, military sub-entries.
• 🪖 Military features — ellipses, sectors, donuts, MIL-STD-2525 symbols via milsymbol.
• 💬 Popups & tooltips — declarative and programmatic overlay API.
• ⏱️ Time-series playback — 60FPS animation timing loop running off-zone via requestAnimationFrame and a premium <ol-timeline> control panel.

📥 Installation:

pnpm add @angular-helpers/openlayers ol

• Unified APIs for common browser capabilities.
• Strict TypeScript support and better autocomplete.
• Practical examples and ready-to-use patterns.
• End-to-end browser test coverage in CI.

• ReDoS prevention tools for regex-heavy flows.
• Permission-aware wrappers for sensitive APIs.
• Worker-based isolation for expensive operations.
• Predictable error handling paths.

• Built for modern Angular versions and patterns.
• Browser-focused utilities tested with Playwright.
• Actively maintained workflows and test harnesses.
