Rule ID #

SF-0134

Impact #

Directly importing css and javascript files without using static resources increases load times.

Remediation #

Use static resources to serve JavaScript files, as well as images, CSS, and other non-changing files. JavaScript and other assets served this way benefit from the caching and content distribution network (CDN) built into Salesforce.
