How to give {{application.path}} in custom component?

Content

Hi 

I am using custom component 'mfe-file-picker' where I need to give the image path as {{application.path}} so that if migrated to new version then also it should take application path instead of hardcoding the src image path.

PFB the HTML

 <img slot="startIcon" data-bind="attr: { src: droparea}"/>

PFB the JS

 self.properties = context.properties;
 self.fullPath = self.properties.applicationPath;
 self.droparea = ko.observable('');

self.droparea(self.fullPath + 'resources/images/dropArea_arrow_ena.png');

I hope that the question is clear that instead of hardcoding like

"<img slot="startIcon" :src="../../webApps/csp/resources/images/dropArea_arrow_ena.png">"
