📥 Building & Running

Prerequisites

# Check Rust installation
rustc --version  # Should be 1.60+
rustup update    # Update to latest

Build for Development

cd c:\Users\Soumalya\Desktop\programming\github_repos\hyprbrowser
cargo build

Output: target/debug/hyprbrowser.exe (~50MB) Time: ~2-5 minutes on first build

Build for Production

cargo build --release

Output: target/release/hyprbrowser.exe (~3MB) Time: ~5-15 minutes (includes optimizations)

Run the Application

# Method 1: From cargo
cargo run

# Method 2: From binary
.\target\release\hyprbrowser.exe

# Method 3: Debug
.\target\debug\hyprbrowser.exe

Troubleshooting

Issue: "error: package tauri does not have feature window-blur"

Status: ✅ FIXED (uses window-all instead)

Issue: Long first-time build

Reason: Downloading ~100 crate dependencies
Solution: Normal, first build takes 5-15 minutes

Issue: WebView2 not found (Windows)

Solution: Install from https://developer.microsoft.com/en-us/microsoft-edge/webview2/

Issue: font.ttf not loading

Verify: File exists at dist/font.ttf
Check: CSS @font-face declaration in index.html

Issue: icon.ico not appearing

Verify: File exists at assets/icon.ico
Check: tauri.conf.json references correct path
