This is a simple proof of concept, exemplifying a way to perform pre fetching on demand of mapped states html templates.

Created a mechanism that loads the template when the 'ui-sref' directive is present. Through the value assigned to ui-sref, the state's settings are retrieved and the html loading done, this can be seen in src/ui-sref.decorator.js

Some things that can be improved:

• Does not load template when directive is disabled.
• Multiple requests to load the same template at the same time. See load method in TemplateLoader service, one option would be to check if the template is already being loaded.
• Only prefetching when the application is idle, thus ensuring that the main requisites are not impaired due to lack of resources.

To run, any http server can be used:

cd src && python -m SimpleHTTPServer

Open the browser debug and check the requests.
