Jatin K MalikandGitHub 0d9c488d82 fix: optimize PageSpeed Insights performance (#115)
* fix: optimize PageSpeed Insights performance

This commit addresses several PageSpeed Insights issues to improve
the performance score from 56 to a target of 90+.

Changes:
- Add SWC config to output modern ES2022 JavaScript, eliminating
  unnecessary polyfills (~12 KiB savings)
- Convert vocalinux.png to WebP format (17KB vs 207KB - 92% reduction)
- Add OptimizedImage component with WebP/PNG fallback support
- Add _headers file for proper static asset caching (1 year cache
  for immutable assets)
- Configure Next.js with optimizePackageImports for framer-motion
  and lucide-react
- Fix heading hierarchy issue (Quick Install h3 -> h2)
- Add console.log removal in production builds

Expected improvements:
- Image delivery: ~41 KiB savings
- Legacy JavaScript: ~12 KiB savings
- Cache lifetime: 754 KiB proper caching
- Accessibility score: 98 -> 100 (heading order fix)

* test: add coverage for PageSpeed optimization

Add comprehensive test suite for PageSpeed Insights optimization changes:

- WebP image loading tests (optimized-image.tsx)
- next/image component configuration tests (next.config.js)
- _headers file generation and cache header tests
- Lazy loading behavior tests

Includes:
- Jest configuration with TypeScript support
- React Testing Library setup
- 54 test cases covering all PageSpeed optimization features
- Build verification

All tests pass: npm run test
Build passes: npm run build

Vocalinux Users

A seamless free open-source private voice dictation system for Linux, comparable to the built-in solutions on macOS and Windows.

🎉 Alpha Release!

We're excited to share Vocalinux with the community. Try it out and let us know what you think!


✨ Features

  • 🎤 Double-tap Ctrl to start/stop voice dictation
  • ⚡ Real-time transcription with minimal latency
  • 🌎 Universal compatibility across all Linux applications
  • 🔒 Offline operation for privacy and reliability (with VOSK)
  • 🤖 Optional Whisper AI support for enhanced accuracy
  • 🎨 System tray integration with visual status indicators
  • 🔊 Audio feedback for recording status
  • ⚙️ Graphical settings dialog for easy configuration

🚀 Quick Install

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash -s -- --tag=v0.4.1-alpha

Note

: Installs v0.4.1-alpha. For the most recent version, check GitHub Releases.

This will:

  • Clone the repository to ~/.local/share/vocalinux-install
  • Install all system dependencies
  • Set up a virtual environment in ~/.local/share/vocalinux/venv
  • Install both VOSK and Whisper AI speech engines:
    • VOSK: installs the vosk Python package from PyPI
    • Whisper: installs the openai-whisper package from PyPI, which also pulls in PyTorch (the ML framework Whisper requires)
  • Create a symlink at ~/.local/bin/vocalinux
  • Download the default Whisper tiny speech model (~75MB)

⏱️ Note: Installation takes ~5-10 minutes due to Whisper AI dependencies (PyTorch with CUDA support, ~2.3GB).

Whisper with CPU-only PyTorch (no NVIDIA GPU needed):

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash -s -- --tag=v0.4.1-alpha --whisper-cpu

This installs Whisper with CPU-only PyTorch (~200MB instead of ~2.3GB). Works great for systems without NVIDIA GPU.

For low-RAM systems (8GB or less) - VOSK only:

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash -s -- --tag=v0.4.1-alpha --no-whisper

This skips Whisper installation entirely and configures VOSK as the default engine.

Alternative: Install from Source

# Clone the repository
git clone https://github.com/jatinkrmalik/vocalinux.git
cd vocalinux

# Run the installer (will prompt for Whisper)
./install.sh

# Or with Whisper support
./install.sh --with-whisper

The installer handles everything: system dependencies, Python environment, speech models, and desktop integration.

After Installation

# If ~/.local/bin is in your PATH (recommended):
vocalinux

# Or activate the virtual environment first:
source ~/.local/bin/activate-vocalinux.sh
vocalinux

# Or run directly:
~/.local/share/vocalinux/venv/bin/vocalinux

Or launch it from your application menu!

Uninstall

# If installed via curl:
curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/uninstall.sh | bash

# If installed from source:
./uninstall.sh

📋 Requirements

  • OS: Ubuntu 22.04+ (other Linux distros may work)
  • Python: 3.8 or newer
  • Display: X11 or Wayland
  • Hardware: Microphone for voice input
