node-gtk lets you build native GTK apps on linux, macOS and windows with full ESM, TypeScript and CSS hot-reload support. Prebuilt binaries are available for Node.js versions 22, 24 and 26.

Usage

The create tool generates a complete, ready-to-run GTK/Adwaita project, so you can start building immediately after installing GTK4:

npx node-gtk create <your-app>

Also see our hello world, web browser or system monitor examples.

Installing

There are two steps:

1. Install node-gtk itself (done by the create tool)
2. Install the native libraries you use (see examples per platform below)

Linux

# archlinux
pacman -S gtk4 libadwaita

# fedora
dnf install gtk4 libadwaita

# ubuntu
# Already installed :)

macOS

brew install gtk4 libadwaita adwaita-icon-theme

Windows

# Already installed :)

[!NOTE] Windows doesn't have the dependencies we need in a package manager, therefore node-gtk ships prebuilt versions of GTK 4 / Adwaita, so npm install node-gtk is all you need if your dependency is in our list of prebuilt libraries.

Other notes

node-gtk is a gobject-introspection library for nodejs. It makes it possible to use any introspected C library, such as GTK, usable. It is similar in essence to GJS or PyGObject.
