JSPM Resource Bundles
This repo demonstrates loading external files on-demand using JSPM/SystemJS. In this specific example, I'm loading language resource bundles from an external CDN.
Although conceptually, the process isn't a complex one, it's taken me some time to figure out how to achieve this.
With SystemJS Builder, externally mapped resources always seemed to be needed to be in-lined into the production bundle. In a use case such of loading the possibility of dozens of large language resource bundles, this would be a problem.
