Building CodeNomad Binaries

This guide explains how to build distributable binaries for CodeNomad.

Prerequisites

• Bun - Package manager and runtime
• Node.js - For electron-builder
• Electron Builder - Installed via devDependencies

Quick Start

All commands now run inside the workspace packages. From the repo root you can target the Electron app package directly:

npm run build --workspace @neuralnomads/codenomad-electron-app

Build for Current Platform (macOS default)

bun run build:binaries

This builds for macOS (Universal - Intel + Apple Silicon) by default.

Platform-Specific Builds

macOS

# Universal (Intel + Apple Silicon) - Recommended
bun run build:mac

# Intel only (x64)
bun run build:mac-x64

# Apple Silicon only (ARM64)
bun run build:mac-arm64

Output formats: .dmg, .zip

Windows

# x64 (64-bit Intel/AMD)
bun run build:win

# ARM64 (Windows on ARM)
bun run build:win-arm64

Output formats: .exe (NSIS installer), .zip

Linux

# x64 (64-bit)
bun run build:linux

# ARM64
bun run build:linux-arm64

Output formats: .AppImage, .deb, .tar.gz

Build All Platforms

bun run build:all

⚠️ Note: Cross-platform builds may have limitations. Build on the target platform for best results.

Build Process

The build script performs these steps:

1. Build @neuralnomads/codenomad → Produces the CLI dist/ bundle (also rebuilds the UI assets it serves)
2. Compile TypeScript + bundle with Vite → Electron main, preload, and renderer output in dist/
3. Package with electron-builder → Platform-specific binaries

Output

Binaries are generated in the release/ directory:

release/
├── CodeNomad-0.1.0-mac-universal.dmg
├── CodeNomad-0.1.0-mac-universal.zip
├── CodeNomad-0.1.0-win-x64.exe
├── CodeNomad-0.1.0-linux-x64.AppImage
└── ...

File Naming Convention

CodeNomad-{version}-{os}-{arch}.{ext}

• version: From package.json (e.g., 0.1.0)
• os: mac, win, linux
• arch: x64, arm64, universal
• ext: dmg, zip, exe, AppImage, deb, tar.gz

Platform Requirements

macOS

• Build on: macOS 10.13+
• Run on: macOS 10.13+
• Code signing: Optional (recommended for distribution)

Windows

• Build on: Windows 10+, macOS, or Linux
• Run on: Windows 10+
• Code signing: Optional (recommended for distribution)

Linux

• Build on: Any platform
• Run on: Ubuntu 18.04+, Debian 10+, Fedora 32+, Arch
• Dependencies: Varies by distro

Troubleshooting

Build fails on macOS

# Install Xcode Command Line Tools
xcode-select --install

Build fails on Linux

# Install dependencies (Debian/Ubuntu)
sudo apt-get install -y rpm

# Install dependencies (Fedora)
sudo dnf install -y rpm-build

"electron-builder not found"

# Install dependencies
bun install

Build is slow

• Use platform-specific builds instead of build:all
• Close other applications to free up resources
• Use SSD for faster I/O

Development vs Production

Development:

bun run dev           # Hot reload, no packaging

Production:

bun run build:binaries # Full build + packaging

CI/CD Integration

Example GitHub Actions workflow:

name: Build Binaries

on:
  push:
    tags:
      - "v*"

jobs:
  build-mac:
    runs-on: macos-latest
    steps:
      - uses: actions/checkout@v3
      - uses: oven-sh/setup-bun@v1
      - run: bun install
      - run: bun run build:mac

  build-win:
    runs-on: windows-latest
    steps:
      - uses: actions/checkout@v3
      - uses: oven-sh/setup-bun@v1
      - run: bun install
      - run: bun run build:win

  build-linux:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: oven-sh/setup-bun@v1
      - run: bun install
      - run: bun run build:linux

Advanced Configuration

Edit package.json → build section to customize:

• App icon
• Code signing
• Installer options
• File associations
• Auto-update settings

See electron-builder docs for details.

Brand Assets

• images/CodeNomad-Icon.png — primary asset for in-app logo placements and the 1024×1024 master icon used to generate packaged app icons

To update the binaries:

1. Run node scripts/generate-icons.js images/CodeNomad-Icon.png electron/resources to round the corners and emit fresh icon.icns, icon.ico, and icon.png files.
2. (Optional) Pass --radius to tweak the corner curvature or --name to change the filename prefix.
3. If you prefer manual control, export images/CodeNomad-Icon.png with your tool of choice and place the generated files in electron/resources/.

Clean Build

Remove previous builds:

rm -rf release/ dist/
bun run build:binaries

FAQ

Q: Can I build for Windows on macOS?
A: Yes, but native binaries (e.g., DMG) require the target OS.

Q: How large are the binaries?
A: Approximately 100-150 MB (includes Electron runtime).

Q: Do I need code signing?
A: Not required, but recommended for public distribution to avoid security warnings.

Q: How do I update the version?
A: Update version in package.json, then rebuild.
