    QML Browserify

    Browserify for QML


    npm install -g qml-browserify


    Bundle a js file: qml-browserify -i index.js -o bundle.js

    Bundle all dependencies in a module: qml-browserify -o bundle.js

    Bundle and print to the console: qml-browserify -i index.js

    Bundle without global variable: qml-browserify --globals

    Bundle with Timer pollyfill (see below for setup): qml-browserify --timer

    Bundle with Promise pollyfill: qml-browserify --promise


    After bundling, import the bundled js file into your qml with something similar to import 'bundle.js' as Bundle. If you bundled a file you can use Bundle.modules as what you exported from your file (this could be a object, function, etc, depending on what you export). If you bundled your dependencies you can use Bundle.modules and an object containing all the dependencies.

    For a complete example, check out the example program in the example directory.

    Using the Timer pollyfill

    In order to use the Timer pollyfill you have to use a qml Timer component and call Bundle.setupTimeout() with the id of that Timer. This pollyfill is very limited and should be used with caution! For example:

    Timer {
      id: timer
      property var callback: function() {}
      interval: 500
      running: false
      repeat: false
      onTriggered: {
    Component.onCompleted: {

    Promise pollyfill

    The Promise pollyfill used by qml-browserify is Promise by taylorhakes
