Get Started


npm install neft -g
neft create MyApp
cd MyApp
neft run node browser --watch

... and play with MyApp/views/index.html;

or alternatively:

  • neft run ios --watch,
  • neft run android --watch.


To install Neft make sure you have installed Node.js in version 4.0.0 or newer. Node is an open-source JavaScript runtime environment. See installation instruction for Linux distributions, type brew install node under OSX or choco install nodejs.install under Windows. For more informations see

Then you can easily install Neft on your machine by typing npm install neft -g in your terminal.

npm is the package manager for JavaScript installed by default in Node.js.

Now you can type neft and see the help page.

Creating app

Neft application is a folder with standardized structure and package.json file.

It's recommended to create application folder by typing neft create MyAppName.

This command creates folder (e.g. MyAppName) with main view (views/index.html) and meta-data package.json file.

Running app

Each time you change the code of your application, you need to build the bundle. You can do this by typing neft build browser. In place of browser provide a platform you want to support. You can choose from node, browser, ios and android.

By typing, for instance, neft run ios you will automatically build and run the application.

If you want to run your application in a browser (neft run browser), make sure you firstly run node server (neft run node) which serves all needed files for the browser.

Server hostname and port are defined in the package.json file. It's localhost:3000 by default.

WebGL renderer

By default, Neft uses the HTML renderer in a browser.

If you want to use the WebGL renderer you can:

  • change the config.type to game in package.json,
  • use /neft-type=game/ URI (e.g. http://localhost:3000/neft-type=game/).

Text mode

If you want to disable the renderer in a browser and see how Google see your page, you can:

  • change the config.type to text in package.json,
  • use /neft-type=text/ URI (e.g. http://localhost:3000/neft-type=text/).

Production mode

When you are ready to publish your app, build client bundles using the --release flag.

neft run node --release

In the release mode, code is minified and all assertions are removed.

Local configuration file

In your application folder, you can find local.json file.

This file is used to configure your local environment. It's ignored by Git (see .gitignore file in your application folder).


To build APK and run your application on Android device, you need to specify where, on your machine Android SDK is placed. See android.sdkDir in your local.json file.

Watching on changes

To speed up coding, you can automatically rebuild the bundle each time you change something. Type neft build android --watch or whatever platform you want to support.

Application run in native environment will automatically restart.

To make it works, you will need to specify in your local.json file. We recommend to use your machine IP address.

Changing static files or custom native code requires you to rerun your application on a device manually.
