NodeGui

All Contributors JS Party #96 Build and Test status Discuss on GitHub

Build performant, native and cross-platform desktop applications with Node.js and CSS like styling.🚀

NodeGUI is powered by Qt6 💚 which makes it CPU and memory efficient as compared to other chromium based solutions like Electron.

If you are looking for React based version, check out: React NodeGUI.

If you are looking for Vue based version, check out: Vue NodeGUI.

If you are looking for Svelte based version, check out: Svelte NodeGUI

How does it look?

Code Examples

https://github.com/nodegui/examples

Features

  • 🧬 Cross platform. Works on major Linux flavours, Windows, and MacOS.
  • 📉 Low CPU and memory footprint. Current CPU stays at 0% on idle and memory usage is under 20MB for a Hello World program.
  • 💅 Styling with CSS (includes actual cascading). Also has full support for Flexbox layout (thanks to Yoga).
  • ✅ Complete Nodejs API support (Currently runs on Node v16.x - and is easily upgradable). Hence has access to all Nodejs compatible NPM modules.
  • 🎪 Native widget event listener support. Supports all events available from Qt / NodeJs.
  • 💸 Can be used for Commercial applications.
  • 🕵️‍♂️ Good Devtools support.
  • 📚 Good documentation and website.
  • 🧙‍♂️ Good documentation for contributors.
  • 🦹🏻‍♀️ Good support for dark mode (Thanks to Qt).
  • 🏅First class Typescript support. (Works on regular JS projects too 😉).

Getting Started

Installation

To install latest stable release:

npm install @nodegui/nodegui

To install the latest version available on master branch:

npm install https://github.com/nodegui/nodegui/releases/download/v0.0.0-latest-master/nodegui-master.tgz

or a shorter version:

npm i http://master-release.nodegui.org

If the installation fails to download the Qt binaries, a mirror can be used by setting the following environment variable and running the install command again:

QT_LINK_MIRROR=<alternative domain> # eg. QT_LINK_MIRROR=https://qt-mirror.dannhauer.de

npm install @nodegui/nodegui

Building from source

This section is useful for those wanting to work on NodeGui itself.

Required tooling

NodeGui requires CMake and Compilation Tools as it is a wrapper for a native C++ widget toolkit QT. Detailed instructions here: https://www.sitepoint.com/build-native-desktop-gif-searcher-app-using-nodegui/

TL;DR:

MacOS

brew install cmake
brew install make

Windows

https://cmake.org/download/

Linux (Debian/Ubuntu)

sudo apt-get install pkg-config build-essential
sudo apt-get install cmake make
sudo apt-get install mesa-common-dev libglu1-mesa-dev

Linux (Fedora/RHEL/CentOS)

sudo dnf groupinstall "Development Tools" "Development Libraries"
sudo dnf groupinstall "C Development Tools and Libraries"
sudo dnf install mesa-libGL mesa-libGL-devel

Building

Once you have cloned this git repository, run this to build:

npm install
npm run build

The last step will takes some time to run as it builds the C++ binaries at the core of NodeGui.

Using your own custom Qt installation (Optional)

Compiling Qt from source

You will need to download and install Qt from source since there are no binaries from Qt for M1 yet.

(https://www.reddit.com/r/QtFramework/comments/ll58wg/how_to_build_qt_creator_for_macos_arm64_a_guide/)

git clone git://code.qt.io/qt/qt5.git
cd qt5
git checkout 5.15

./init-repository --module-subset=essential -f
git submodule init qtsvg
git submodule update qtsvg

cd ..
mkdir qt5-5.15-macOS-release
cd qt5-5.15-macOS-release

../qt5/configure -release QMAKE_APPLE_DEVICE_ARCHS=arm64 -opensource -confirm-license -nomake examples -nomake tests -skip qt3d -skip webengine -skip qtactiveqt -skip qtcanvas3d  -skip qtdeclarative -skip qtdatavis3d -skip qtdoc -skip qtgamepad -skip qtcharts -skip qtgraphicaleffects -skip qtlocation  -skip qtpurchasing -skip qtquickcontrols -skip qtquickcontrols2 -skip qtremoteobjects -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtserialport -skip qtspeech -skip qtvirtualkeyboard -skip qtscript

make -j15

make install

This should install Qt into something like this /usr/local/Qt-5.15.3 (your directory can change. This will be displayed when running make)

Pointing nodegui to use your custom Qt installation

Now just set export QT_INSTALL_DIR=<your qt path> . In the above example it would look something like this export QT_INSTALL_DIR=/usr/local/Qt-5.15.3. Add this in your .zshrc or .bashrc so that you dont need to repeat this process again.

Now just rm -rf node_modules and do npm install again.

The logs should say something like CustomQt detected at <your qt path>. Hence, skipping Mini Qt installation.

Running example programs

A number of small programs to show different parts of the Qt API are in src/examples. They can be run directly with:

npm run qode dist/examples/modelview_1_readonly.js

Updating docs

npm run docs

then followed by:

cd website && GIT_USER=<your_git_username> yarn deploy
