::: warning Experimental The Linux platform is experimental. See Developing for Linux. :::

A release build packs the app into a .tar.gz archive that users can extract and run, or install for the current user with the included install script:

ns build linux --release

The archive is written to platforms/linux/<ProjectName>/dist/<ProjectName>.tar.gz, and the folder it was created from to platforms/linux/<ProjectName>/dist/<ProjectName>/.

The app id names the app's desktop entry (<app id>.desktop), its icon and its install folder, and GTK uses it to match the app's windows to the desktop entry. It defaults to your app id (id, or linux.id) and must be a reverse DNS name, for example org.nativescript.MyApp.

The version shown in the app's AppStream metadata is the version of your package.json.

Replace App_Resources/Linux/icon.png (512×512) or add an icon.svg, and update app.desktop and app.metainfo.xml with your app's name, categories, summary and description. See App_Resources › Linux.

Each build targets a single architecture, the architecture of the build machine by default. Use --arch to choose x64 or arm64:

ns build linux --release --arch arm64

Apps with native code are compiled by the build machine's C compiler, so build them on a machine of the target architecture.

Release packages run on glibc based distributions with glibc 2.28 or newer and GTK 4. Libraries your native code links to must be installed on the user's machine too.

MyApp/
├─ MyApp                     # the app executable
├─ app.nsbundle              # the app's JavaScript and assets
├─ app.nsbundle.unpacked/    # files kept outside of the bundle (fonts by default)
├─ metadata-x86_64.bin       # C API metadata
├─ metadata/                 # metadata of the app's and plugins' native code

└─ install.sh

By default, the app's files are packed into a single read-only app.nsbundle, and the executable is locked to it:

• the bundle's integrity is checked against a hash stored in the executable
• the executable only loads the app from the bundle
• the debugger, command line flags and environment variable overrides are turned off

These settings are configurable. Files that need to stay real files (fonts by default) are listed in linux.bundleUnpack.

To encrypt the bundle with a key embedded in the executable, enable linux.sourceProtect or build with --source-protect:

ns build linux --release --source-protect

A new key is generated for every build. To use your own, pass --source-protect-key-hex <key> or set the NS_LINUX_BUNDLE_KEY environment variable.

Users extract the archive and run install.sh:

tar -xzf MyApp.tar.gz
./MyApp/install.sh

The script installs the app for the current user, without root privileges:

• the app is copied to ~/.local/share/<app id>/
• the desktop entry is written to ~/.local/share/applications/<app id>.desktop, so the app shows up in the desktop's app launcher
• the icons are copied to ~/.local/share/icons/

To uninstall the app, remove those files.

The app can also be run without installing it, by running the executable in the extracted folder.

The CLI doesn't produce AppImage, Flatpak, Snap, .deb or .rpm packages yet. The release folder (platforms/linux/<ProjectName>/dist/<ProjectName>/) contains everything the app needs, including an AppStream metainfo.xml and a desktop entry, and can be used as the input for those packaging tools.
