To achieve code instrumentation, a tool called grunt-plato was used to analyze the javascript used to develop the application.

An example report can be seen here

Instrumentation for server-side javascript was split from the front-end javascript. The base directory for these generated reports is:

.reports/plato

To generate instrumentation reports, run:

$ grunt plato

Output:

UI Reports Location: .reports/plato/ui

Server Reports Location: .reports/plato/server
