Browserify javascript bundler plugin.      Examples:          Simple example::              IEVVTASKS_BUILDSTATIC_APPS = ievvbuildstatic.config.Apps(                 ievvbuildstatic.config.App(                     appname='demoapp',                     version='1.0.0',                     plugins=[                         ievvbuildstatic.browserify_jsbuild.Plugin(                             sourcefile='app.js',                             destinationfile='app.js',                         ),                     ]                 )             )          Custom source folder example::              IEVVTASKS_BUILDSTATIC_APPS = ievvbuildstatic.config.Apps(                 ievvbuildstatic.config.App(                     appname='demoapp',                     version='1.0.0',                     plugins=[                         ievvbuildstatic.browserify_jsbuild.Plugin(                             sourcefolder=os.path.join('scripts', 'javascript', 'api'),                             sourcefile='api.js',                             destinationfile='api.js',                         ),                     ]                 )             ) Parameters:             sourcefile: The source file relative to ``sourcefolder``.             destinationfile: Path to destination file relative to ``destinationfolder``.             sourcefolder: The folder where ``sourcefiles`` is located relative to                 the source folder of the :class:`~ievv_opensource.utils.ievvbuild.config.App`.                 Defaults to ``scripts/javascript``.             destinationfolder: The folder where ``destinationfile`` is located relative to                 the destination folder of the :class:`~ievv_opensource.utils.ievvbuild.config.App`.                 Defaults to ``scripts/``.             extra_watchfolders: List of extra folders to watch for changes.                 Relative to the source folder of the                 :class:`~ievv_opensource.utils.ievvbuild.config.App`.             **kwargs: Kwargs for :class:`ievv_opensource.utils.ievvbuildstatic.pluginbase.Plugin`. Installs the ``browserify`` NPM package.          The package is installed with no version specified, so you         probably want to freeze the version using the         :class:`ievv_opensource.utils.ievvbuildstatic.npminstall.Plugin` plugin. Get extra browserify args.          Override this in subclasses to add transforms and such. Make browserify args list.          Adds the following in the listed order:          - ``-d`` if the ``sourcemap`` kwarg is ``True``.         - the source file.         - ``-d <destination file path>``.         - whatever :meth:`.get_browserify_extra_args` returns.          Should normally not be extended. Extend :meth:`.get_browserify_extra_args`         instead. Called at the start of run(), after the initial command start logmessage,         but before any other code is executed.          Does nothing by default, but subclasses can hook in         configuration code here if they need to generate config         files, perform validation of file structure, etc. We only watch the folder where the javascript is located,         so this returns the absolute path of the ``sourcefolder``. Returns a list of the extensions to watch for in watch mode.          Defaults to ``['js']``.          Unless you have complex needs, it is probably easier to override         this than overriding         :meth:`~ievv_opensource.utils.ievvbuildstatic.pluginbase.Plugin.get_watch_regexes`.
