Building with webpack

If you are creating your own app.js and not using the provided bundled one, the source will need to be compiled using webpack.

Before building create an isolated bootstrap css file to not polute the container application with boostrap styles.

node node_modules/hslayers-ng/scripts/bootstrap-isolate.js

Example webpack configuration files are provided at https://github.com/hslayers/examples/tree/webpack/full

        $scope.hsl_path = config.hsl_path; //Get this from hslayers.js file
        /* Core component is responsible for bootstrapping the application and managing top level interface such as panels and toolbar */
        $scope.Core = Core;

        /* We can listen to event emited by components such as layer manager and hide a layer which was added by code or by user for example*/

        /* To hide certain panels even if they are loaded as a dependency to other component use panelEnabled function */
        Core.panelEnabled('compositions', false);
        Core.panelEnabled('permalink', false);

    }

To build execute in terminal:

webpack --config webpack.dev.conf --progress
