Bedford Module Coding - A Short Course

The Short course, taught by Trevor Bedford & Sarah Cobey, examines the importance of using safeObject and SafeClass implementations. The Permissions model is also covered. The Permissions model requires the use of import maps. The interfaces must use SafeObject and SafeClass implementations.

Import maps should be used for Permissions Model

Import maps can be used to manage permissions in an app that is scalable. Instead of manually creating lists, import maps automatically populate lists of groups and users by analyzing their origin and destinations. Developers and Bedford car diagnostics administrators will find it much easier to manage permissions. However import maps have limitations.

Import maps are integrated into HTML documents using the script type="importmap" tag. This tag must be placed before any script type="moduletag" in a document. This ensures that the import map is processed prior to the module resolution process. At present, only one import map can be loaded per document. However, the future plans call for removing this restriction.

Interfaces should be using SafeObject or SafeClass implementations

Interfaces used for Bedford module coding should make use of SafeObject or SafeClass implementation. Although this may seem confusing, it is intended to provide security assurances. In particular, Bedford Module Coding interfaces should utilize a secure interface to avoid capability or information spillage.
