The general class of errors are 404s for scripts (not found), network timeouts or errors in the scripts that are loaded. RequireJS has a few tools to deal with them: require-specific errbacks, a "paths" array config, and a global requirejs.onError. The error object passed to errbacks and the global requirejs.onError function will usually contain two custom properties: requireType: A string value with a general classification, like "timeout", "nodefine", "scripterror". requireModules: an array of module names/URLs that timed out. If you get an error with a requireModules, it probably means other modules that depend on the modules in that requireModules array are not defined.
